No more than 5 inches away, try 3-4. And get a fan on them to blow the heat away

2-3 inches even without good ventilation, especially with only 23w cfls, just make sure the temp isn't above 90.

1-2 inches is best. If a CFL is 4 inches away instead of 1 inch away it is delivering only one-sixteenth the amount of light. If your plants got burned then they had to be touching the bulb, and that indeed is too close.
