Built with an integrated driver, the housing maintains a flush, unobtrusive aesthetic. This clever engineering allows the panel to transition beyond basic recessed installations to support multiple configurations—including a surface mount frame or a suspension kit—depending on your specific layout constraints.
🚀 Advanced Technical Performance & On-Site Flexibility
Multi-Wattage Power Selection
Eliminate ordering errors and accommodate varying ceiling heights on a single project. This 1×4 recessed LED light fixture features adjustable wattage switches that let you toggle between four power tiers:
20W / 25W / 30W / 35W Power Selection
High Luminous Efficacy: Delivering an impressive 120–125 lm/W, prioritizing severe energy savings and utility rebate qualification.
Total Lumens: Produces a powerful 4200–4375 lm at peak output, guaranteeing superior brightness and energy efficiency.
4-CCT Switchable White Technology
Achieve perfect color coordination across your entire floor plan. With a built-in switchable white CCT selector, you can adjust the color temperature right on the fixture prior to installation:
3000K (Warm White) – Ideal for reception desks, hospitality accents, and comfortable breakout areas.
3500K (Warm/Neutral White) – Popular for corporate corridors and balanced open offices.
4000K (Cool White) – Standard specification for high-focus task environments and conference rooms.

❓ Frequently Asked Questions
Q: Can this 1×4 recessed LED light fixture be wired into emergency backup systems?
A: Yes. The fixture features a universal 120V-277V integral architecture that easily pairs with a wide range of standard field-installed emergency battery backup drivers.
Q: What is the primary benefit of an edge-lit flat panel compared to a direct-lit troffer luminaire?
A: Edge-lit panels route light from the perimeter LEDs through a light guide plate, scattering the beam evenly across a frosted lens. This creates a completely shadowless, glare-free profile that prevents harsh screen reflections—perfect for computer-intensive office environments.
Q: How do I change the wattage or color temperature after buying?
A: There are physical dip-switches located securely on the back of the integrated driver housing. Simply flick the switches to your desired CCT or power setting before snapping the fixture into the ceiling grid.
