One novel thought occurs to me (also from watching too much Home Front) -
I=
f
you are seriously considering using LED's, then have you thought of
using=20
fibre-optic as an alternative?
You could have a light source indoors, and then run either single or
bundle=
s
of fibre to wherever you want a point of light. - I would guess that the=20
light level would be comparable to LED's? - you're obviously not going
to=20
get great illumination from either, so I'm guessing that it's more for=20
effect...
Then you wouldn't have to run any electrickery outside at all, and you
coul=
d
change the light colour at anytime by changing the light source... Whereas=
=20
once you'd fitted LED's you'd be stuck with whatever colour they were....
