Impressed by the 12V Led in my office task light I wanted to upgrade the reading lights in our bedroom. I had previously fitted a couple of IKEA spot lights that take small Edison screw (SES) bulbs on the assumption that a small CFL would be fine given the proximity to the book.
However we always seemed to end up with main bedroom lights on as well, due to old age and failing eyesight.
Some time in Google failed to turn up a suitable direct fit LED so I finally took the plunge and ordered a couple of GU10 bulbs from Amazon and hacked a GU10 to SES adaptor (don't try this at home!) http://tr.im/BbB5
Very pleased with the result, much more efficient than CFLs I have tried. Beam angle is quite narrow and the wider version that costs a few quid more might have been better in this application.
I'm still sceptical of the approach of ceilings full of LED downlights as so often seen, eg BRE Innovation Park, but for local task and accent lighting I think LEDs have come of age. Can expect to see price drop and performance increase still further in next year or two but current offering seem to work well enough and the price isnt silly unless you insist on lighting your kitchen with an array of 20 down lighters (fit one T5).
Look forward to hearing of other's experience and recommendations now Philips and others have products available or about to be.
