Our body temperature is a lot warmer than the mat will be you can't tell by touching it. Heat mats all get up to around the same temperature, no matter how low or high the wattage is, higher wattage heat mats just tell you that it's bigger and therefore need more electricity to power it. However, some small heat mats with higher wattage than the normal ones are designed to get hotter. Trust me, if you put a digital thermometer on that mat you'll be shocked and if not then there's something wrong with the mat itself. I wasn't suggesting that it did, it's just in case you'd think that you wouldn't need d3 in your supplements but you would as they lamps aren't UVB ones. I'm also sure those canopies weren't designed for that heat lamp but the flat long ones and no higher than 25watts. Trust me, I know what I'm talking about, I've been in your situation and had many trial and errors
