Re: Anyone moved to LED Lighting?

[John Perry <jpnews@xxxxxxxxxxxxxxxxxxx>]

I have tried a range of GU 10 LEDs.

16 LED units using 2W, and totally inadequate.

48 LED units imported from China; they had a greenish hue, but
inadequate brightness and too green/blue.

60 LED warm lights that give the right colour balance, but not really
bright enough. No failures in 2 years, we use some for background
lighting.

60 LED daylight units that are too white/bright. No failures in 2
years.

78 LED warm units, these are easily bright enough and equivalent to
20W halogens.  We use around 40 of these.

78 LED daylight units, again easily bright enough, but too white and
un-natural.

12 LED SMD warm; these are excellent, very bright and we use about 40
of these.  These are slightly brighter and whiter than the 78 LED warm
units.

12 LED SMD daylight; these are excellent, very bright and we use them
in the kitchen.

16 LED colour changing; we use these at Christmas time for fun.

No interference with X-10 so far, but I think they are killing the
signal between my wireless weather station and external sensors.

Sorry for the delay in replying.

The units barely get warm, and use less energy than CFLs as the CFLs
get hot.

All GU10s are in fire cowls, but covered with fibreglass with no
cut-outs as required for halogen.  If 50W halogen units are put in our
housings, we would have a serious fire risk.
