Just after some opinions on Metal Halide vs Halogen and fluorescent lighting
for outdoor use...
I am after the most energy efficient lamp that is practical to illuminate a
patio area, a 500w halogen does the job well, but is 500w, obviously.
I am not bothered if there is a few minute warm up time, as I won't be using
it for PIR activation, just general use when having a BBQ etc.
My options seem to be, stay with a standard 500w halogen, go for a
fluorescent like this

Or a metal halide unit
like this 70w one

or this 150w one

What is the average lamp life of these units, and the approximate halogen
equivalent light output?
Thanks!
