yeah if you get the correct temp from it.if not then higher the basking branch a little or if its too hot then higher the bulb.failing that you may need to get a lower wattage.halogens do give off more heat than an incandescent bulb tho.how do you cope without a thermostat.i couldnt be without one.im using just a 40w spot bulb and thats on a dimming stat.that gets above 35c without being plugged into a stat.i couldnt be without it and run the risk of burning my boy.
