Generally not. Choosing the correct (household incandescent) basking bulb is usually a matter of trial & error of wattage & distance (and sometimes bulb type). Some can get away with as low as a 40W. From experience, I started at 60W (which wasn't enough), then 75W then 100W. I settled on a 75W halogen flood (not spot) mounted at an angle to provide a gradient (range of temperatures). You want to heat the basking area, but not so close to the screen that you can't keep your hand on the screen; if you can't keep your hand there, the cham may get burned, so raise the light or try a lower wattage.do the t5s create sufficient heat for a basking spot
