When you have no money for photographic equipment you have to make do with what you can. I help run the village photographic club and I have to think up ways to teach them how to make a good photograph. I made up this homemade studio with clip on lights and MDF boards sprayed black. I also have a homemade white deflector/diffuser. Here is the link to the picture of the studio and what I achieved.

White light balance is so good these days. I would say don't mix up low energy lights with ordinary light bulbs.
