For a tank thayt size I'd be tempted to use 2 430W Philips
Son-Agro. Ostesnibly a 400W Metal Halide (MH) bulb, but with a 30W
High Pressure Sodium (HPS) capsule insde as well to put out extra
red light - which MH is lousy at making, but is important
for happy (and colorful) plants.

Of you could go the el-cheapo route and use hardware store
"security" lights. two 150W mecury vapour (MV) and one 70W
HPS, you'd spend very little but more light tha you'd
probably ever need.

I don't know about anywhere else, but Costco here has
150W MV's for $38 CDN, and 70W HPS are around for about
$80 CDN. Thats with bulbs and ballasts, although you'd
probably want'need to take them apart and mount just 
the parts you need.
