Over the past few years I have experimented with several types of LEDs for use as layout lighting in part of my basement that houses Aquia Landing and the Port of Los Angeles Layouts. These rooms have 12 recessed can lights in the ceiling. Note that the front room of the layout from Brooke to Falmouth has a built-in valance with tube florescent fixtures. If I could, I would get rid of all those lights.
Ultilitech Pro 120W BR 40 Floods. Lowes is the only store in my area that carries them.
These lights create a nice even flood of light. They are dimmable and only use 20W of power for 1400 lumens of light. They cost about $20 a pop, but should last a long time.
