Go to Home Depot and get a couple "Y" splitter bulb sockets - about $2.50 each...then you can put them into a smaller socket that has a plug on it (usually found right next to the "Y" splitters on the store shelf). Plug into a medium to heavy duty extension cord and hang them above your grow area, then use a timer on the other end so you don't have to worry about keeping the light schedule yourself. You can get a decent timer for about $10 - be sure it has the three prong outlets on it so your extension cords will fit (some are only two prongs, like for a simple table lamp to plug into it). If you want to run all four lights off just one extension cord, you can get a work light for about $6.50 (the kind with the plastic cage that you can hang from your car hood when working under it). Remove the plastic bulb protector cage, and plug it right into your cord - the Depot sells a sturdy gray/orange one with an on/off switch and extra outlet on it, so you can piggyback a second pair of CFLs off there just by plugging them into that extra outlet. I've got that same setup going with four CFLs from one cord, and there have been no problems. I added a thin string to the second light pairing so that I can tie it off to the closet rod for better positioning and weight support. I'm lucky to have an unused closet to grow in, so I have the empty rod to use as a hanging place for lighting and whatever else is necessary. Sure makes it easy to adjust lighting positions...
