DIY HOB lighting

I'm thinking about building a couple HOB lights for my tanks. One will be for my 10g and other for my 29g. The ballast for both will be mounted low and behind as a counterweight to hold the head a few inches above the open top. The 10g will get a M85 (70 watt) metal halide in a "stand light" head. The 29g will get a M59 (175 watt) metal halide in a "pole light" reflector as part of its head.

Main question: what material do you think would be best for this project? Cost very important, as is weight.

Gutter looks like it could be a good head for fluorescent or M98 (70 watt "yard lite") , but is too honkin' big for much else. However, I do have some 3/4" PVC I can try for the 10g light. I don't see it being stiff enough for the 29g light.

I also would like to enclose the top of the 29g's reflector.

3/4" ? I may not be following correctly? ? You're wanting to build a whole light hood with existing hardware? You could use 4+" pic and rip it in half the long way

That is a lot of wattage. Are you injecting CO2? What are your plans as far as plants ?

I am experimenting with growing plants, with no real long term plans except to see what grows. I also like HID lighting.

With that much wattage you may be growing algae. If you want an inexpensive solution: go to Lowes or Home Depot, get a clamp lamp for each tank, maybe 2 for the 29 gallon, and three 23Watt(100 watt equivalent), 6500K CFL bulbs.

I've seen those. I had a pair of 15 watt CFL's when I started but it still looked extremely dark. While I managed to modify the hood to accept a pair of 25 watt CFLs. However I've already started working on this project and am feeling froggy.

Also, where can I find CFLs in 8000K or 10000K above 20 watts?

Lowes or Home Depot ONLNE. Maybe Fleabay. For plants, I would go with 6500K.
