you can find them at home depot, or lowes...they usually are a clamp light with an aluminum hood. just take the hood off, and buy a 2-way splitter. and BAM! you got yourself a lil cfl double pumper
just about any hardware store has them, walmart has them. find someone wearing a vest and a nametag and make them figure it out if you really cant do it yourself. buy garage sale lamps for .50 cents and break them. seriously now, how many stoners does it take to screw in a light bulb?!?
those will work perfect and are pretty cheap. sorry if i came off as an asshole earlier, long day, better now. best of luck, check my journal and ask if i can help in any way! good luck!
