Just bought 3 of these, 2 in 15w-1100 lumens and 1 in 25w-1800 lumens, non-dimmable ceiling fixtures. I installed one of the 15w to replace a similar fixture using 2 x 15w pin tube florescents. Much brighter, whiter light, looks nearly like the Solatube tube light we have in the same hallway. The 25w is going to replace a 20w x 4 florescent fixture, and the other 15w will replace another ceiling fixture.
