5000 hours? Not all that good. Half will be burned out in 3 years of
regular use (about 5 hours a day).

I've been considering both MR16 (GU5.3 12v) and MR11 (what pin for 6v?)
for various lighting fixtures in the home I'll be building. I may opt
for the smaller ones so I can select the illumination level by turning
selected lights on and off rather than dimming. My original idea was
to go with 6 volt 12 watt lights if those are available in MR11 or some
other kind of halogen form factor.

What I don't like about these lights is the pitch of the facet in the
reflector. I would like the pitch to be about 10 to 20 times smaller.
A frosted glass would, of course, help, too.
