The 15" Slim Flush Mount is a 0.65 in deep ceiling fixture with five colour temperatures and three wattages, both set at install. One SKU covers 24W, 28W and 32W.
Output runs 2,100 to 2,800 lm at CRI above 90. Pick 2700K, 3000K, 3500K, 4000K or 5000K on the fixture itself.
cETLus listed for damp locations, 2.5kV surge protection built in, 50,000 hours rated, five-year warranty.
How big should a flush mount ceiling light be?
Add the room's length and width in feet, then use that total in inches as the fixture diameter. A 15 in fixture suits a space near 7 by 8 ft on that rule.
Commercial jobs work backwards from light levels instead. This one puts 2,100 to 2,800 lm through a 120 degree beam from a housing 0.65 in deep, so it clears low ceilings, sloped ceilings and corridors with no plenum depth to give up.
What is the brightest flush mount ceiling light?
At this size, brightness depends on two switches, not one. The wattage selector sets 24W, 28W or 32W. The colour selector changes output again.
Votatec's photometry (EVERFINE lab, tested 2025-12-01) measures the 32W step at 2,377 lm at 2700K and 2,871 lm at 3500K. That's a 494 lm swing on the same fixture at the same wattage. Warm settings cost light. Spec the colour temperature before you count fixtures.
Will it fit the box you already have?
It needs a compartment of Ø15" by 0.65". Nothing above the ceiling.
The supplied plate mounts to a standard electrical outlet box with the two screws in the carton, driven fully home. Wire white to white and black to black, using the three wire nuts supplied or a push-in Quick Connector. The fixture then rotates and pushes onto the plate, with no screws through the trim. It mounts horizontally or vertically and runs from -20°C to 40°C.
Why CRI 90 costs you lumens per watt
High-CRI phosphor converts less of the same wattage into visible light. That's the trade for colour that holds up in retail displays, exam rooms and finished residential work, where the CRI 80 baseline flattens reds.
