My monitor can get pretty close to my bulb and have never noticed any blistering on his back and I use a hotter bulb than that. Maybe it's the bulb you're using? I don't know I just haven't ever had a problem with blistering. He seems to know when he's getting warm, and when he's cold because he's always moving from basking spot to basking spot to regulate his temperature.
