Built to take a job site
The housing is steel in a clean white finish, closed by a polycarbonate frost lens that diffuses the 180 SMD 2835 diodes into one smooth luminous surface instead of visible dots. That frost lens is the reason this 1x4 LED troffer meets or exceeds DLC 5.1 glare criteria: staff working under it all day get comfortable light instead of a bright bar burning in the corner of their eye. Each fixture weighs 5.60 KG, and anti-seismic mounting clips are included in the box — a detail that matters on institutional and commercial jobs where the inspector will look for them.
Light quality and selectable output
Five colour temperatures are selectable on the fixture: 3500K, 4000K, 5000K, 5700K and 6500K. Five wattages are selectable too — 40, 30, 25, 20 and 15W — so the same product can light a quiet reception area or a production bench. At full output the fixture delivers 6,179 lumens with an efficiency of 126.36 lm/W and a maximum real power draw of 48.9 W. The CRI of 82.9 and 180° beam angle give broad, natural-looking coverage, and the LEDs are flicker-free, which is what you want over screens and in classrooms. L70 lumen maintenance is rated at 50,000 hours.
Electrical and installation
The universal 120-347V input at 50/60Hz is the big time-saver: the same troffer goes on a 120V residential circuit or a 347V commercial panel, so you stock one item instead of three. Internally the LED array runs at DC 120-140V and 0.27A. Power factor is 99.5 % and THD is 13 %, with 2KV surge protection both with and without MALT. Dimming is 0-10V DC, so pair it with a standard 0-10V wall control for meeting rooms, classrooms and multi-purpose spaces. There is no photocell and no occupancy sensor built in, so add external controls if the project calls for them. Installation is surface mount or suspended, and the operating temperature range is -20°C to 45°C, which covers unheated garages and shop spaces as well as conditioned interiors.

Applications and documentation
Think open-plan offices and private offices, school classrooms and staff rooms, dental and physiotherapy clinics, pharmacies and retail aisles, condo and apartment corridors, church halls, municipal garages, hair salons and finished basements. In a renovation, a row of these recessed troffer fixtures surface-mounted on a low basement ceiling replaces tired fluorescent strips with far less energy — LED technology cuts consumption dramatically compared to old fluorescent and halogen sources. On a commercial retrofit, the 120-347V input means one item code for the whole building. The IP20 rating keeps it indoors and dry: no wet locations, no exterior soffits. Full photometrics, the nomenclature table and packaging data are in the technical PDF available in the Documentation tab — worth downloading before you submit the fixture for approval.
