I use anything and everything. I use flashlights, christmas tree lights, the little "spotlights" from the Michaels Christmas and Halloween Town villages, the little flexible neck LED lights that come with a laser pointer from Walmart or AM/PM's, the little lights that you stick in closets that are battery powered and you just push on them to turn them on, floral string lights from Michaels. Every light gives it's own qualities. Just buy a few small lights and see what kind of effects they give. As for big lights, I just use a regular lamp and different colored bulbs sometimes. I also have floodlights and a snake light from Black and decker.
