I used the 66 LED units from Germany for my new kitchen downlights and quickly ditched them for the 7 watt CFL GU10 from Tesco. Reliabilty is a big issue when using several LED's in series. Manufacturers often quote the life of a single LED!
These are useful for mood lighting, pictures, decorative use etc.
My local Sainsbury (Wrexham) had a alot of lamps reduced by 75% including LED, 2 function (flourescent stick with integrated LED) etc so may be worth a look when out shopping in your local Sainsbury.
If yuu want to save electricty and have decent light levels, wait for Tesco to do the GU10 compact flourescents on BOGOF i.e. £2.49 each.
I did wonder whether some / all of the LEDs are in series. In which case reliability reduces by a factor equal to the number in series, but even then it could be better than Halogen.
I may try the compact flourecent GU10, has anyone tried a CFl replacement for MR16 12V fiting ?
Here is review of diff GU10's :
