Re: GU10 Energy efficient replacements

["Kevin" <kw1816@xxxxxxxxxxx>]

Thanks for all the responses - I bought a selection of both dimmable
and non dimming SMD's to try out. Will report back on how I find them. I've
got over 50 GU10's so it may take a while to replace them all :-0

Cheers

choice a bit overwhelming so I'd like to try out a couple of different
types (e.g. LED or CFL)to see which work for us. Dimming would be nice but
it's not required for most of our rooms. They're for recessed fittings so
must be the same physical size as a normal GU10.
