How cold is it in the room you have the tank in? My 75 watt infrared bulb lights my 20 gallon long tank just fine on the medium dial setting. The room the tank sits in is heated by a space heater to 75-80 degrees (compared to below 70 in the rest of the house) so it's pretty easy to get the tank temps right.
