Yes...but with a few things to keep in mind. First don't position the bulb over where the matt is...you run the risk of overheating the matt (which can lead to a fire). Secondly I haven't used a bulb with a proportional thermostat but my guess is that typically incandscent bulbs don't last long when you run fluctuating power to them...so you can expect that the bulb won't last long. I still recommend you replace the bulb with a ceramic heater (does the same thing just no light and will work just fine with the Herpstat.Originally Posted by alilshadee
