Was your old bulb ceramic? Or a black light bulb? I used to use infra red. If the wattage is the same it shouldnt be too terribly different though, in my experience ceramic put out slightly less heat. Though if your heat pad gives the warm side an ambient of 94 i sould NOT add a heat lamp. A light bulb for day time maybe. But not additional heat. The baski g area (the warmest spot) should be around 89-91 degrees.

Just my 2 cents, but I would reccomend either using an additional thermometer to be sure about your temps or invest in a heat gun(theyre like 100 dollers at home depot). Heat pads keep himidity better and provide belly warmpth which aids in digestion, bit there is the possibility that it can overheat to a dangerous level if unregulated, whixh would result in burns or death for your little guy.

I use heat lamps myself, and a 100 wat ceramic heat lamp I leave on all the time keepz my temps at 90 degrees consistantly by itself. (though in some tanks I have to adjust the lamps distance from the screen using command strips to get the exact number I want) IT works for me anyway..
