Finally, a spot-on replacement!,

After trying many, many kinds of low energy bulbs, including multi-LED, single LED and fluorescent types, I've FINALLY found one that's perfect! Normally the LED ones suffer from either a lack of brightness and overly directional light beam (in the case of bulbs with many individual LEDs), or take too long to warm up (fluorescent) or are too off-white - either "warm white" (which is often more yellow than a halogen) or "cold white" which is too blueish, or they are too big for the socket.
These are different - they have one extra-bright LED and then - critically - a diffraction lens that spreads the light out evenly, so that you get an even better dispersion than with a traditional halogen. The pure white output is spot on and the first genuine pure white I've found. The bulb is identical size to a normal halogen.
They may be expensive but they are worth it - my kitchen is now full of them, and my energy consumption has been slashed from 210W to just 18W!
Finally I'm happy with LED bulbs!
Presence UK (a.k.a. Music & Laughter) have been great, swapping out a bulb when I mistakenly ordered a wrong one to try - very much recommend them (and no I'm not affiliated with them in any way, I just appreciate good service).
(And yes, this is the same review I did for the MR16 fitting version of the bulb, since I use both)
