I use a clip on light, but after speaking to my husband over the weekend about the problems I have in dimly lit places and my tent being too wobbly to attach the light to,(forcing me to clip to the top of the nearest door) he came up with a fabulous suggestion. He says that fluorescent lights dont throw shadows like other lights would. He is a builder and uses them for when he is plastering where he cant afford shadows affecting the final smoothness and finish of his work. Anyway, I was going to have a little look for a small striplight or a flourescent portble light and give it a try. The ones in the builders merchants are a bit pricey and look like they should be on a building site, but in the meantime I think I will try to tan in the customers kitchens as most kitchens have flourescent lights I think
