reptile lights?

[weaselslucks]

OK so i am cycling a 29 gallon 17 inch high tank.eventualy i want to have soft corals however, my money problems have made me rethink the light for now.I would like to put in LR from refferrock.com because it has a lot of life on the rock.i have a regular 18 w bulb in the hood I have now i can change that out with a coral grow one or something. I also have two reptile(looks like florecent) full spectrum 18 w (each)units.my question is could i get away with one of these light set ups and keep most of whats on the LR alive?if so which one. eventually i thought i could get the light and add a little mor LR to seed the tank if most of the things die.

oh one more thing should i add it while cycleing or will all the goodies on the rocks die from the large spikes?

thanks

When cycling the rock most goodies will die, but some will come back to life.
I don't know the rating of your lights, but I use flourecent lighting from home depot and they are rated at 5000k to 6700k on the packaging and rated at 20 - 40 watts and they do good in an aquarium. They are cheap at $5 a tube and gowth is good.
I use six 40 watts in a 120gal and everything flourishing!
