Cooper Lighting Metalux 24CGTS-L3C3 Back-Lit Selectable LED Panel Light, 21W

The Cooper Lighting Metalux 24CGTS-L3C3 is a back-lit LED panel light engineered for commercial ceiling installations that call for flexible light output and color temperature at the job site. Operating on a universal 120-277-Volt input, this 21-Watt fixture delivers up to 3100 lumens with 80 CRI color rendering, giving installers field-selectable CCT options of 3500K, 4000K, or 5000K to match project requirements without stocking multiple SKUs. The selectable lumen and CCT design of this Metalux™ panel simplifies inventory management for electrical contractors and facility managers alike.

Key Features

  • Selectable Color Temperature: Field-adjustable between 3500K, 4000K, and 5000K to match a range of lighting design needs on a single fixture.
  • Light Output: Delivers up to 3100 lumens at 21-Watts, providing efficient illumination for offices, retail, and general commercial spaces.
  • Universal Voltage: 120 - 277-Volt input allows installation across standard commercial electrical systems without additional transformers.
  • Color Rendering: 80 CRI ensures accurate, true-to-life color rendering for occupied commercial interiors.
  • Back-Lit LED Design: Distributes light evenly across the panel surface for a uniform, glare-reduced appearance in drop-ceiling applications.
  • Selectable Lumen Output: Adjustable lumen packages allow one fixture to serve multiple lighting level requirements, reducing SKU complexity for distributors and contractors.

Cooper Lighting 24CGTS-L3C3 – Frequently Asked Questions

1) Will the Cooper Metalux 24CGTS-L3C3 LED panel run on 277V, or do I need a separate driver for it?
No extra transformer or driver is needed. The Metalux 24CGTS-L3C3 panel has a universal input rated 120-277V, so the same fixture works on 120V tenant circuits and on 277V commercial lighting branch circuits. That is what lets a contractor carry one fixture across buildings with different distribution voltages.
2) How do you set the color temperature on the Metalux 24CGTS selectable panel?
Color temperature is selected in the field, not ordered. The 24CGTS-L3C3 is switch-selectable between 3500K, 4000K and 5000K, so one panel covers a warm-neutral office look, a neutral white, and a cooler daylight tone. Set it to match the existing fixtures in the space before you lift it into the grid.
3) Is 3100 lumens at 21 watts enough for a general office ceiling?
The 24CGTS-L3C3 delivers up to 3100 lumens drawing 21W, which is the usual output band for general ambient lighting in offices, retail floors and classrooms laid out on a drop-ceiling grid. It is an ambient panel, not a task or high-bay fixture, so for warehouse or high-ceiling work you want a higher-output product instead. The panel is also selectable on lumen output, so the same fixture can be dialed to serve a lower light level where the design calls for it.
4) What is the difference between a back-lit LED panel like this Metalux and an edge-lit panel?
Back-lit panels put the LEDs behind the diffuser across the whole face, which spreads output evenly over the panel surface and softens the glare you get from a bright edge-lit light guide. The 24CGTS-L3C3 is the back-lit type and is intended for drop-ceiling grid installations. Edge-lit panels are generally thinner, so if your plenum depth is the constraint rather than appearance, that is the type to look at.
5) Is 80 CRI good enough for retail, or do I need 90 CRI?
The 24CGTS-L3C3 is an 80 CRI fixture, which is the standard rendering level for offices, corridors, classrooms and general retail sales floors. If you are lighting merchandise where color accuracy sells the product (apparel, cosmetics, paint, food display) or a healthcare exam space, specify a 90+ CRI panel instead.
6) Can I standardize a whole building on one Cooper panel instead of stocking several CCTs?
That is the point of the selectable design. Because CCT is field-set among 3500K, 4000K and 5000K and the lumen output is selectable too, a facility can stock the single 24CGTS-L3C3 and still match offices, corridors and back-of-house that were originally built with different color temperatures. The 120-277V input removes the second stocking variable.
7) What is the exact part number to order this Cooper Metalux selectable panel?
Order it as Cooper Lighting Metalux 24CGTS-L3C3. That one catalog number covers the 21W, 3100 lumen, 80 CRI, 120-277V back-lit panel with the 3500K/4000K/5000K selectable setting, so there is no finish or voltage suffix to add on the order.
