They sell PVC rain gutter in 10 foot lengths for about $5 a section in
most big box stores. It comes in White or Brown. They also sell Left
and Right end caps, which merely snap onto the PVC rain gutter. PVC
rain gutter can be cut easy with a fine tooth blade (hack saw works
great) or even pair of snips, or score with knife and
snap...........anyway you do it, its just plain easay to work with.
YOu can buy el cheapo shop lights (typical 48" long 40watt 2 lamp
fixtures) for $10 to 15 at most big box stores as well, but they lack
a decent reflector and side sheilds, plus they are metal so are prone
to rust etc, and do not lend themselves to being modified very well.
However, using PVC gutter and end caps (a left and right) its easy to
gut a typical shop light assembly and install it in a piece of PVC
gutter which is cut to length to fit bulbs plus sockets as well as
fit on the tanks top frame..........its PVC and its non conductive so
its much safer overall than a metal fixture is.........You can buy
good reflectors that fit inside these PVC gutters and it merely wedges
inside or can be held in place with double faced
tape..............Gutters can be had in widths of 4" or 5 inches and
even a 4" wide can easily be made to hold 2 typcial florescent
tubes............A small muffin (Pancake) fan can be added if
additional cooling is necessary, and these can be bought at Radio
shack or any computer supply place for a few bucks.......they come in
AC or DC voltages so pick one that suits yuor situation the best. They
do make a difference in keeping a light cooler and that helps with
prolonging bulb life and not adding latent heat to a tank............
