Tying grow lights to a shelf....

(I thought I posted this but maybe I'm just losing it)

I am about to buy some grow lights, either T5 tek lights w/4 lights, 2 warm & 2 cool, or New Wave T5 tek lights w/4 lights, 2 warm & 2 cool. looking at info from here: http://www.homeharvest.com/teklighthighoutputfluorescents.htm and an email from here: http://www.4hydroponics.com/lighting/HighOutputFluorescents.asp the only difference is the fancy black outer housing on the Tek Light, and the new wave cost less.

I think I remember seeing a picture on another forum of light setup with such a light tied to a homedepot like metal shelf. That made me want to buy a shelf from HD and attach the light myself rather than spend several hundered on a grow shelf.

My question is, did I see what I think I saw--someone has tied their lights to a shelf? Has anyone tried this?

Thanks,

Maureen

BTW, Growco http://www.4hydroponics.com/ has free shipping all the time on lights.
