I did not know it was so easy! I just cut the transformer off of this desk light and attached a cigarette lighter plug. The florescent light I bought on the internet and is made for 12-volt. I just ordered a 12-volt compact florescent light that only uses 11 watts. (Note the spliter). I will cut the end off a lamp and convert to 12-volt with another CL Plug from Radio Shack. What else can I do.
