I've just had a wierd problem.

I bought some cheap dimmable warm-white cfl's ("econutters" 20w, four for twenty quid).

but found a wierd problem, it blocked my infrared set-top box remote control! needless to say I'm back to an filament lamp for now!

has anyone else come across this and is so know of any dimmable cfls or led's that don't cause the problem?
