Youre absolutely fine with aluminum foil, you're not pushing massive HID's so no worries. If you cant burn your hands by proximity to your bulbs, theres no way the aluminum foil is going to be able to concentrate the light from your cfl into something so powerful it can burn your plants
I wish there were a way to squash this aluminum foil myth forever.
