[Rhodes22-list] Environment

Joe,

I also use a coil spot outside - rigged to a light detector 
to illuminate the US flag and USMC colors.  It has lasted 
longer than any of the halogen types that I used to use, 
and draws less than half the power.  In that case, the slow 
warm-up is not a problem.  Incidentally, it functions even 
in sub-zero temperatures, which the average FL light cannot 
handle.

For the lights that are on motion detectors, I stuck with 
the halogens, as they are quick.  The shock effect helps
(a little) to keep the deer away from the azaleas.  So 
dies the concentrated human scent that I apply.
