LUMI believes new products are key to any business growth, therefore we announce many new products throughout the year. You can subscribe to LUMI email updates which will provide you with information on the latest models along with tips and pointers that will improve product sales. In addition, your LUMI sales representative will provide you with specific detailed product information suited to your business needs on a direct basis.

LUMI was established in 2005, R&D and production growth quickly followed. Though some of our facilities are mature, they are regularly evaluated for improvement and upgrades of processes, equipment and material handling. We also operate new facilities that specialize in the manufacture of emerging markets, including monitor arms, ergonomic furniture and accessories. In addition, LUMI strictly follows changes in environmental and labor law to ensure our facilities are operating ethically, legally and morally to our workers and the communities we are part of.

As an example, our largest factory is capable of producing over 10 million TV mounts a year and currently has over 600 employees. During non-busy periods, LUMI factories normally operate within a 60-70% capacity. It's important to understand that due to seasonal trends and situations that impact production demand (such as the recent pandemic), customers should always maintain close contact with their LUMI sales professional in order to identify any trends that will impact business and the delivery of the product.

Other than for on-going testing and sampling needs, LUMI manufactures products on demand and does not maintain an inventory of products. We also maintain raw materials based on existing and projected needs. Purchase orders from our customers trigger raw materials placement and then are entered into the production calendar, and everything is allocated from packaging to labor requirements. LUMI's customized ERP system tracks the flow of every order to ensure the fastest and most accurate production as possible. Once the production process is complete, the delivery of the products is arranged based on the customer's requirements.

Like any quality manufacturer, LUMI recognizes that quality people produce quality products. However, the realities of limited available labor and the importance of training and rewarding staff are areas that LUMI allocates a great deal of time and energy to. In China, it is common for 30% of factory workers not to return after the Chinese New Year break. This is normally due to family or other obligations that the worker(s) have and is not an indication of poor treatment or other negatives. This is a cultural phenomenon that every Chinese factory must manage. LUMI constantly works to both train and reward workers for their achievements. Our Human Resources area pays close attention to staffing needs and invests in on-going training to ensure we have the best and the most satisfying workforce in the industry.

Yes! All of our factories meet strict standards and are audited frequently. We are certified by ISO 9001, ISO 14001, FSC, Sedex, BSCI and other well-known auditing agencies. We own a complete audit profile that includes detailed information required by our customers to perform a factory audit. Our intent is to provide the most thorough, detailed information in order to enhance the confidence of our customers. In addition, LUMI factories carry the necessary worldwide certifications that our customers require to sell products in each of their respective markets.

LUMI HQ and LUMI factories are both ISO rated or operating to ISO principles and guidelines. You can contact us anytime for further information and clarification about how we operate and to what standards.

From a national and local perspective, China has been advancing Labor and Green laws to protect workers and the environment with the goal of positioning China as the global leader in both of these areas. LUMI maintains close ties with government regulators in order to join the effort in achieving this goal.

BSCI is the most notable auditor of Business Social Compliance of factories in China. LUMI has successfully been audited by BSCI and other certified auditing agencies. In addition to following audit recommendations, LUMI has established its own guidelines for ensuring sustainability in the area of social compliance issues.

Generally speaking, the majority of LUMI products (TV and AV mounting devices, ergonomic furniture, carts and accessories) are not required to carry the CE Mark in order to be sold in the European market. This is due to the fact that CE Directive BS EN 292 does not apply to non-powered equipment such as LUMI products. Since our products can only be used to position devices where the operator provides all moving force (meaning that the motion of the product will stop immediately when the operator ceases to apply force to the product) our products do not fall under the definition of machinery as defined in BS EN 292. Electric or Electronic devices (or hybrid products that combine both mechanical/electronic design) are normally required to carry the CE Mark and therefore are tested for compliance under CE guidelines.

Yes, many of LUMI's products carry the TÜV GS Certification Mark. Contact your LUMI Representative for specific model details.

Yes, many of LUMI's products carry the UL Certification Mark. UL is a global leader in safety certifications and the UL MARK is the most accepted Certification Mark in the United States. LUMI is one of the few manufacturers that operate an in-house UL Witness Test Data Lab. This allows us to perform safety testing on-premises for designs that we are creating for the general market and for our OEM/ODM customers. Having the ability to pre-test provides our customers with the confidence in knowing the product being developed meets quality standards prior to applying for formal certification. Contact your LUMI Representative for specific model details.

In order to evaluate and certify products, UL and TÜV use product samples in their test processes. While both UL and TÜV maintain their own extensive test facilities, a select number of their customers (such as LUMI) qualify to utilize their own in-house test facilities and equipment. Through these Witness Test Data Programs product evaluation can be conducted at LUMI headquarters under the supervision of UL and TÜV personnel. LUMI's standard laboratory has officially acquired UL and TÜV lab certification and employs our internal test lab in the evaluation of products. The laboratory, physical resources, equipment, personnel and procedures that LUMI adopts are equivalent to the processes and equipment used in UL and TÜV's own test laboratories.

LUMI believes in being a responsible manufacturer as it relates to the environment. Our Corporate GREEN initiative promotes the use and recycling of raw materials including rubber and steel products. Our factory obtained BSCI Certification and all of the products we produce meet the major international environmental directives such as RoHS and RoHS 2 (Restriction of Hazardous Substances in Electrical and Electronic Equipment).

Yes. In general, LUMI mounts are tested to hold 3 or 4 times the stated load capacity. In order to assure absolute safety in actual use, we strictly limit the rated capacity of our products.

LUMI takes product safety very seriously. LUMI has assessed that some of its products contain one or more substances found on the Prop 65 Substance List, therefore warnings may be required. Although Prop 65 only applies in the state of California USA, LUMI sells to customers located around the world and in markets each with their own requirements. Therefore, LUMI will work to assist customers that may be required to address the labeling and notification requirements of Prop 65. For further information about Prop 65, please visit http://www.p65warnings.ca.gov/ .

LUMI factories use standard Incoming Quality Control (IQC) as the process of controlling the quality of materials and parts for manufacturing a product before production begins. With incoming inspection, LUMI controls quality even before conducting a first article inspection or during production inspection.

LUMI uses industry-standard IPQC (in-process quality control) processes. These are checks that are carried out before the manufacturing process is completed. The function of in-process controls is monitoring and if necessary adaption of the manufacturing process in order to comply with the specifications.

Again, LUMI uses industry-standard QC protocols for QC. 1st finished products coming off the line are inspected based on product specification and functional ability. Any corrective action that needs to take place is performed. As 30% of the production is completed, they are checked for quality and production status along with the monitoring of any corrective action. Packing does not begin until there is a check of all labeling and packing methods prior to beginning the final process. These elements are the basics for a final QC, however, LUMI customers can work with our QC team to develop customized quality processes based on their requirements.

Absolutely! For safety and certification, we maintain close relationships with test labs in China. This allows us to supplement our internal test data with outside professional testing resources as well.

The sample lead time for most standard products is within one week. Production samples are available approximately 45 days after the receipt of the order. Full production orders can vary, please contact us for specific product lead times.

Depending on the item, LUMI offers free or reduced cost for most samples. Contact your LUMI Representative for assistance.

Common carriers are used most often to ship samples. If you are already purchasing from LUMI and have an order in process, samples of new products can be shipped along with your standard products. Contact us for details.

It is the responsibility of the importer to cover costs associated with the import of goods. Therefore, LUMI cannot address these costs.

Yes, each individual packaging contains an English installation manual. The customized manual is also available with an MOQ of 1000 pieces.

Most LUMI products are packaged in Gift Boxes. We also provide the following packaging for certain products: Brown Box, White Box, Clam Shell, Blister Card, PET Folded Box, and Poly Bag. Besides, customized packaging is also available. We have professional design staff to create the packaging and support materials you need to be a leader as you market and sell our products. We work closely with our customers to understand and create designs according to their specific requirements.

All LUMI products carry a Limited Warranty against manufacturing defects in materials and workmanship. Please refer to the LUMI  Warranty for further information or contact your LUMI Representative for further details.

There are a few options for you when it comes to shipping products from LUMI (China) to your facility:
1. D.I.Y.  –  Manage Your Own Freight for Full Control
New to novice-level importers typically choose this freight management process. The pro to this option is that all you have to do is instruct LUMI to ship cargo as CIF "Port of Destination" or DAP "Your facility Address".
2. Work with a Freight Forwarder
This is the most convenient option for companies that purchase from LUMI. Companies also tend to prefer the idea of working with a freight forwarder that's based on their home turf for extra peace of mind, more transparency, and faster communication. Using a freight forwarder may increase your overall cost when importing products into your locations.
· FOB (Freight on Board)
This is the most popular method for importers/buyers of LUMI. We are responsible for transporting goods from their place of origin and having the goods loaded onto the vessel at the container port. Once loaded onto the China shipping container, the risk of loss or damage transfers from LUMI to the importer/buyer. From this point on, the importer is responsible for all insurance and transportation costs. It will also be the importer's responsibility to ensure goods clear customs. This method is known to be one of the cheapest ways to ship from China to the USA.
· CIF (Cost Insurance Freight)
LUMI is responsible for the transportation of goods from the place of origin to the port of destination. LUMI is also responsible for purchasing insurance on behalf of the importer/buyer. However, once loaded onto the vessel, the importer/buyer will assume any risk of damaged or lost goods and will need to file an insurance claim in such a case.
· CFR (Cost and Freight)
LUMI is responsible for the transportation of goods to the port of destination along with all associated costs. Liability is transferred to the importer/buyer once goods are placed on board the vessel. The importer/buyer is responsible for payment of port handling costs at the port of destination and land or rail transportation to the destination warehouse.
· OTHER
Contact your LUMI Representative should you require any other type of delivery requirements.

Yes, LUMI is here to help you. Contact your LUMI Representative if you need any assistance or have specific requirements. You can also find additional information on the US Customs website by clicking HERE.

Yes, LUMI ships both FCL and LCL for our customers. These are the two basic options given when importing products from overseas. Your official quote will contain information on the number of units required to fill most container sizes. However, the general rule of thumb is that if you purchase about 10 or more pallets of product, FCL (Full Container Load) is the best choice. FCL is the most cost-effective container choice and is calculated by the cost per volume metric and unit weight. Full containers come in 20 ft, 40 ft, and 40 ft high (HC or HQ) variations. For businesses importing smaller volumes of goods, LCL (Less than Container Load) is the alternative solution. LCL is shared container freight where several buyers store their goods in a single container. Although LCL is a great option for the smallest businesses, the downside is the cost is higher per volumetric. There are normally other fees associated with shipping LCL and LUMI can help you understand the process should you be shipping LCL.

IMPORTANT NOTE: Due to recent circumstances in the shipping and logistics industry, the lead time for moving products from China to anywhere in the world has been increased 2 and 3 fold in both cost and lead times. Please plan your purchases well in advance of your need. Contact your LUMI Representative for details.

Normally, the time it takes to ship from China to the United States may vary slightly depending on the destination port. West coast cities such as Los Angeles, Oakland, and Portland have an approximate lead time of 20 days. East coast cities such as Miami, Jacksonville, Baltimore and New Jersey have lead times of approximately 30 days. It's doesn't happen often, but there may be a scenario where there's an issue with a container ship after it has left the port of origin. In a cumbersome situation such as this, another 10 – 15 days may need to be added to the lead time. NOTE: It is in these cases that a freight forwarder can be quite helpful.

Yes, we can! LUMI listens to our customers. Over time, we've heard the many frustrations that our customers have when dealing with other suppliers. Knowing that many LUMI customers purchase products outside of LUMI's core product areas - we created LUMI Vida.

VESA holes or VESA hole patterns refer to the configuration of the four mounting holes on the back of a flat panel TV or computer monitor. For example, in a 100 x 200 mm VESA pattern, the screw holes are arranged in a rectangle of 100 x 200 mm apart.


LUMI complies with a set of standards set by the VESA Association known as the Flat Display Mounting Interface (FDMI) or Mounting Interface Standard (MIS). This makes it easy to choose a mount that can accommodate and safely hold your display.

All LUMI mounting solutions are VESA compliant and carry the Official VESA Mounting Compliant Seal. Being VESA compliant indicates that our mounts are engineered in accordance with the Flat Display Mounting Interface (FDMI) Standard also known as the Mounting Interface Standard (MIS) as developed by the VESA Organization. The VESA standard defines the dimensions of a display's four-hole attachment interface and the screws used to fit those holes. It also dictates the placement of the hole pattern found on the back of the display. VESA standard hole pattern mounts have the exact hole patterns of the TV already built into them. 


The mounting holes are in the back of a TV and the TV weight determines the exact mount that will fit a TV. LUMI suggests that the consumer determine the weight and mounting hole distance of their TV prior to selecting a suitable mount.

VESA Hole Patterns	Recommended TV Size
100×100	13''-27''
200×100	13''-32''
200×200	23''-42''
400×200	32''-55''
400×400	32''-55''
600×400	37''-70''
800×400	37''-70''
800×600	37''-70''

Brackets or arms refer to the mechanical supporting structures that hold a device in position or elevate monitors, TVs, soundbars and other displays. LUMI designs and manufactures a variety of brackets or arms that are normally part of another structure that performs the task of holding a device. These include monitor arms, TV mounts, speaker mounts and so on. By providing tilting functions, portrait to landscape rotation and other functions, an arm or bracket is an integral part of the overall mechanical design that helps users improve their working posture, obtain the best viewing position and other benefits of being able to position or move a device.

Take LUMI's LDT07-C036 as an example. An articulating arm gives your monitor full horizontal mobility. Articulating arms have multiple adjustable joints and can be pulled forward or pushed back, move up or down and swivel with ease. LUMI provides a variety of articulating arms with smooth mobility and great stability.

There are a variety of different types of TV mounts on the market from fixed to tilt and full-motion. Compared to fixed or tilt, full motion means the greatest range of movement. LUMI's full motion TV mounts provide the most versatility due to having multiple pivot joints, allowing you to move the TV against the wall, away from the wall, tilt it up or down and angle it from side to side. They are a great fit for either home or commercial installations.

A back plate or wall plate is a part of the TV wall mount. TV wall mounts are durable frames that make use of the mounting hole patterns on the back of the TV to grip and hold the TV in place, anchoring it into the wall. A back plate or wall plate is the plate that is attached to the wall prior to attaching the TV to the mount. Back plates or wall plates can be mounted on the wall with or without studs and on many different surface types.

Plumb and level are terms that are frequently used in the field of carpentry. Plumb means vertically flat, it's used to describe the up and down orientation, such as walls of a building. While level means horizontally, perfectly straight from side to side.

Wood studs are usually "two by four" or "two by six" by name. Typical dimensions of today's "two by four" wood stud are 1.5''×3.5'' (38 mm×89 mm). Studs are typically placed 16'' (406 mm) from each other's center but sometimes are placed 12'' (305 mm) or 24'' (610 mm) from each other's center.

Drywall is also known as sheetrock, consisting of a flat panel made of gypsum rock core (calcium sulfate dihydrate) sandwiched in between thick sheets special paper. Sheetrock is a specific brand of the drywall sheet. Drywall and Sheetrock are terms that are often used interchangeably.

In the US, the most common size of drywall is usually 48" (inches) and 1/2" (inch) thick and 8' (feet) length (54'') and 96'' wide are also used with varying lengths to fit different needs. If you need additional country-specific information you can also search online.

Tested 3X or Tested 4X is intuitive data to indicate the load-bearing performance of the product. It means the product's strength has been tested for a minimum of three or four times its stated load capacity.

Vertical or portrait mount is a vertically installed wall mount that is normally used in public areas or commercial applications to provide advertising, data and content that is both eye-catching and informative to attract potential customers. It usually features a tiltable design so the viewing angle can be adjusted flexibly that most patrons can see the display. Due to vertical mounts being primarily located in public areas, the potential for theft makes an anti-theft design a necessity, therefore most vertical portrait mounts incorporate security features.

A horizontal or landscape mount is a horizontally installed TV wall mount that is widely used in the residential environment. It usually features a tiltable design so that users can get the optimal viewing angle. Safety is a major consideration when designing a horizontal or landscape TV wall mount for use in homes, so most of these mounts feature automatic spring locks that allow the TV brackets to snap and lock into place, securing the TV on the wall plate for extra safety.

Allen key, also known as a Hex key, is a simple tool with a hexagonal (hex) head that fits various machine screws and set screws that have hexagonal-shaped recessed holes. Normally, both ends of an Allen key are hexagonal. Therefore, people can use either end to install or remove a hex fastener.

A nut driver is a tool for tightening nuts and bolts. It is similar in appearance to a screwdriver, consisting of a socket attached to a shaft and cylindrical handle. It's widespread, and it's especially useful in low-torque applications where accuracy and control are required.

There are three situations you should consider:
1. On wood, drywall, or sheetrock walls, you need to prepare:

2. On a brick, cement, stucco, concrete block, and stone walls, you need to prepare:

3. Into a wall without studs, you need to prepare:

M-rated screws are metric-sized hardware that is wildly used all over the world for general purposes. Unlike other screws that can be embedded in the wall directly, M-rated screws are usually used to connect components of products.

An anchor bolt is a fastener that consists of three fastening components: an expanding sleeve, a thread bolt, and a nut. The force generated by tightening the nut and bolt together forces the expanding area of the sleeve outwards, gripping the material the sheathing is embedded in. Due to the specific fastening system, it is suitable for connection between porous materials, such as brick, cement, stucco, concrete block, and stone.

Gas spring monitor arms – for the most effortless and smooth adjustment
Gas springs rely on a pressurized gas to store energy. The nitrogen is compressed in an enclosed cylinder and the output force of the gas spring depends on the amount of pressure applied over the gas chamber.

Mechanical spring/spring-assisted monitor arms – for long product lifetimes
Spring-assisted monitor arms are also called mechanical spring monitor arms. The function of height adjustment is achieved by mechanical springs, which are conventional coiled-metal springs. They rely on elastic deformation to store energy when compressed.

Mechanical/articulating monitor arms – for the most competitive cost
Mechanical monitor arm is another name for articulating monitor arm. They don't have springs in the arm assembly. Instead, the articulating joints allow the user to adjust the height, tilt, pivot and rotation of the monitor arm to reach a comfortable ergonomic position. It is the most affordable solution to provide flexible viewing adjustment.

		Gas Spring Monitor Arms	Spring-Assisted (Mechanical Spring) Monitor Arms	Mechanical (Articulating) Monitor Arms
Adjustment	Performance	Effortless and Smooth	Smooth	N/A
	Release Force	Slower and Controlled Release Force	Stronger Release Force
	Operation Noise	Very Quiet	Quiet
Arm Size		Oversized	Standard Size	Slim
Cost		Slightly Higher	Median Priced	Affordable
Life Span		Long Life	Very Long Life	Longest Life
Environment Friendliness		Should be Recycled	Recyclable	Easily Recyclable

There are literally hundreds of ergonomic monitor arms on the market. Of these, there are core differentiations that are clearly visible, like styling, height adjustment range and a number of monitors they'll hold, and then there are those differences that are invisible to the eye—the internal mechanisms. The most significant internal difference between different models is whether they are built using gas cylinders (a.k.a. gas strut, gas piston, or air cylinder) or metal springs (a.k.a. spring coils) to provide their counterbalance force.

Coil springs are used primarily because they are more economical, and have no parts to fail or seals to leak so they also have extreme longevity. This means their force will remain constant as the years go by. They're not as smooth or silent as gas cylinders, and they have a faster "kick back" (stronger release force). The counterbalance forces increase linearly as the spring coils are compressed (see graph below). The force rendered by a spring coil depends on its material, wire thickness, spring diameter, number of coils and length.

Gas cylinders are used primarily for their smooth and silent operation, but they cost a little more and have a moderate lifetime compared to springs. Gas cylinders have a slower "kick back" (controlled release force), and force increases exponentially as they are compressed. It takes less force to compress the system at the beginning of the stroke, at the end of the stroke it requires much more force (see graph below). The force rendered by a gas strut depends on its internal pressure.

Gas vs. Coil Spring "Kick Back" (Release Force)


Summary

Coil Springs	Gas Cylinders
More economical	Cost a little more
Extremely long product lifetimes	Moderate lifetime
Not as smooth or quiet in operation	Smooth, silent operation
Faster "kick back" (strong release force)	Slower "kick back"

A grommet hole is a hole in the desk surface that allows a monitor arm to be mounted to the desk. When not used for a monitor arm, many use the grommet hole to route cables through the tabletop.

There are two types of grommet holes: The larger one is normally 2" and used to pass the cable through as well as mount the arm in a grommet configuration. The second grommet hole is smaller and normally found on workstations (desktop converters) and used strictly to mount an arm to the device.

Grommet mount is a type of installation that allows the user to mount a monitor arm through a hole in the desk surface. Some desks come with a pre-drilled grommet hole that's suitable for this mounting solution. If not, the user will have to drill a through-hole in the desktop before installing the monitor arm. Grommet mounting is highly recommended for multiple screens and large-size screens because it provides increased durability and stability.

Clamp mounting is a type of monitor installation. With clamp mounting, a monitor arm can be attached to the edge of a desktop without any other tools. The desk should have enough depth for the proper installation of a clamp. It is the most popular choice by most people because it does not require a hole to be drilled into the desktop and is very easy to install.

Counterbalance is a feature of mounting solutions designed to provide a better user experience when the screen is being adjusted. With monitor arms or TV mounts that feature counterbalance, the screen can be easily moved and remain stationary at any desired position. The finger-tip adjustment allows for effortless maneuvering and a wide range of movement to adjust the screen's height and angle. There's no need to loosen or tighten parts.

A smart stand refers to a monitor or laptop stand with an integrated USB hub and multi-media ports. It is designed for convenient access to all devices at hand.

There are two ways to use the smart stand:
1. Connect the smart stand with a PC. In this way, the smart stand becomes a USB expansion of the computer. Data and audial signals can be accessed easily by plug in flash drives or headphones into the ports.
2. Connect the smart stand with the power and these ports can be used for charging devices.

Multimedia ports include USB ports, a headphone jack, and a microphone jack. They can be found on some of LUMI's products such as monitor stands and pro gaming monitor arms. With these ports, users can get easy access to power, data and audio signals without reaching the computer.

Cable management refers to a solution dealing with wiring and routing. In order to keep the workspace free from messy cords, LUMI provides organizing solutions for keeping those cords safe, functional and organized. Many products (monitor arms, workstations, and standing desks) have integrated cable management design. In addition, we also offer cable management accessories (such as cable box, cable tray, floor cable cover, cable management spine, and cable sleeve) that help users to create a neatly organized workspace.

Some monitor arms offer fingertip height adjustment so that the monitor can be positioned at any desired height when properly counterbalanced. However, when a monitor is attached to the arm for the first time, the arm may droop or rise by itself if the monitor is too heavy or too light. The tension gauge is for counterbalancing the arm to fit various monitor weights and the tension is shown on a weight indicator or tension indicator.

One additional question may be, how is the tension adjusted? A screw can be found on the arm for tension adjustment. With an Allen Key, users can easily tighten or loosen the screw until the monitor is perfectly balanced and firmly holding the weight of the monitor.

The built-in tension gauge allows the user to mount any screens within the weight capacity. When installing multiple monitors the tension indicator can be used to balance monitors by referencing the balance point when the same make/model of a monitor is used throughout the multi-monitor installation.

Rotation stop is a feature found in some monitor arms that will prevent the arm from over-rotating and entering adjacent space or bumping into walls. It provides a user-selectable 180° or 360° rotation range that prevents the arm from movement beyond the back edge of the workspace or hitting adjacent partitions - perfect for dual-monitor mounting needs, desks near walkways and cubicles that have limited space.

Definition: Product dimensions usually are the Length, Width and Height of a product. As for LUMI's monitor arms, the dimensions refer to the Width, Depth and Height of a product.

Measurement Standards: Dimensions are measured with the arms fully extended, the VESA plates facing forward and the Clamp Knob located on the base tightened. *If the monitor arm is with a pole, d=0 (the distance from the top of the Pole to the top of the Arm Collar of the suspended arm)
Width a: The straight-line distance from left to right. (Take the greater one between a1 and a2.)
Depth b: The straight-line distance from front to back.
Height c: The straight-line distance from top to bottom.

Indeed we do! In fact, LUMI has applied for and has successfully patented products within our product offering that includes intellectual ownership and rights for utility and design. In addition, we take the internal and external steps necessary to protect and defend our important Intellectual Property Ownership and Rights — and this effort extends to the OEM/ODM projects we work on for our customers.
