Pro tip from the counter
The driver is a separate box on an 18.5 in lead that has to go up through the can opening and sit on the housing or ceiling. On shallow cans or tight plenums, check there is room for a 6.69 x 3.15 x 1.57 in box above the aperture before ordering a floor's worth.
Best for: hotel and office lobbies, corridors, retail and supermarket ceilings, schools, CFL downlight upgrades on 277 V circuits
