Be aware though that just putting those led 'incandescent equivalent' bulbs into an existing refector and light fitting is considered to be very bad practice. It's a subject which has be discussed on here previously and I remember that Sean Walsh (of Odyssey Neoplan fame and all-round electrical guru) had very strong opinions on the legality and wisdom of the idea; basically the point is that those led bulbs don't project light in the same way that incandescent bulbs do, and that therefore putting them in a reflector designed for an incandescent bulb doesn't work.
I think we all know how reflectors work, but that doesn't chage the fact that a Christmas tree of leds stuck on a bayonet socket - no matter what angle they're pointing - simply doesn't replicate the single point source that is the filament of an incandescent bulb. I can't quote the specfic code or regulation concerned (as Sean was able to do), but to me it's very significant that the reputable brands such as those mentioned earlier don't have anything to do with the 'led bulb' market, despite the obviously massive potential it apparently offers
