Nope. The lamp is barely on. No smell or discoloration of any kind. HVAC tape is amazing. I suppose if I turned the dimmer up full-blast we
might have problems. We trust the tape on the furnaces of our homes, at much higher temps, so... 75 watt IR bulb dimmed down to almost nothing. Enough to bump up the ambient 5* or so. Come spring I'll be putting the lamp away. It's just for these few cold New Hampshire months. Lou has been under it for a month, now. He's doing fantastic!
