My husband (an electrician) just put 8 recessed lights in the kitchen with a dimmer "switch." When I dim the lights real low, 2 go all the way out while the others stay "on." What is the problem? Thanks for your "help."

Different lamps? This would be my guess.

They are all CFLs (dimmable)from the same box

I have seen many dimmable CFLs have different low thresholds.
Many simple go off. They are not like incandescent lamps we are so familiar with.
