In other words Jeff, you use a bank of several low-wattage lights to have a large area to bask under (meaning the whole lizard can heat up - not just a section of his back). If the basking area is tiny vs. the size of the lizard and the cage is relatively cool, he can inadvertantly burn a small portion of his back trying to heat himself up. In nature, the sun does not heat up a tiny 6" area leaving the rest of the area 70*F. The lizards don't understand this and can burn themselves it seems.
