I think Walmart sells something similar, or you can always order them online. What you're looking for is a clamp on desk lamp, usually artist use them for drawings. You have to make sure your desk have ledges though.

What about LEDs? There some great affordable fixtures out.

another option is to use Walmart's clamp on lights. I bought 2, broke off the clamps, and used some old flat stock steel that I cut, bent to shape, drilled and installed on my sons 20h. I could have gone an inch lower to hide the "T" bracket but I wanted the tank and night stand flush with the wall.

You should do fine. The old rule was "3 watts per gallon" for high light. HC Cuba also loves lots of co2 too.

That is by far, the best looking CFL diy stand I seen. It's barely noticeable, very nice.

Sorry if I missed a similar post somewhere earlier in the post but I am setting up a 90 gallon with CO2 and would be interested in a similar setup. How many fixtures do you think I would need and what wattage for the bulbs to achieve med/high light? Thanks!

Thanks. Once I get some free time, I'm going to take it down and give it a nice coat of semi gloss black paint.

If you're wanting moderate to high light, I don't think this is the method that will get you there with this size tank.

Great topic. I just upgraded my lighting setup on my 90 gallon this weekend. I wanted a cheap alternative. So I went to home depot. Bought two of the white hanging light fixtures for 50 bucks each. Cut some pvc to make it look like a solid setup, painted it black and plugged in 2 100w 6500k 1450 lumen cfl bulbs. I hope I have enough light now.

This is going to be an extremely low light setup. I doubt that you will be able to grow much beyond directly below your fixtures. A 90gal tank is a DEEP tank, and the amount of light that reaches the bottom is very little. Especially when using spiral CFL bulbs; the shape of the bulbs themselves mean that much of the light output is lost in "restrike" rather than being directed down into the tank.

I hate to tell you this after the work you put into this really nice-looking setup, but you would have much more usable light with dual rows of T8 bulbs than with this design.

IMO, trying to light LARGE tanks with spiral flourescents is usually a waste of energy. Strips of flourescent bulbs provide much more usable light per watt and overall better light coverage throughout the tank.

You can use any appropriately rated fixture these bulbs will screw into. How efficient depends on the quality of reflector, mounting position, distance from object, etc
