Re: Re: LED lighting for garden

["Paul Gordon" <paul_gordon@xxxxxxx>]

One novel thought occurs to me (also from watching too much Home Front) -
If
you are seriously considering using LED's, then have you thought of using
fibre-optic as an alternative?

You could have a light source indoors, and then run either single or
bundles
of fibre to wherever you want a point of light. - I would guess that the
light level would be comparable to LED's? - you're obviously not going to
get great illumination from either, so I'm guessing that it's more for
effect...

Then you wouldn't have to run any electrickery outside at all, and you
could
change the light colour at anytime by changing the light source... Whereas
once you'd fitted LED's you'd be stuck with whatever colour they were....
