Bear with me.
My online photo site is done at the moment, dammit.
The pics prob arent to helpful as the light is suspended above my tanks at the mo.
Will include a pic of anothe singler fixture that i have yet to set up.
The lights have had a 3 metre extention cord wired to it as they dint have a cord.
Disclaimer
I suggest you get someone who know what they are doing to do this as electricity can be lethal.
I scrounged around some local electrictians to find some old stye steel reflectors, although you could make one out of wood or something.
Pics will follow once picturetrail.com sorts itself out
