I have one of those Flukers digital humidity/temp gauges. I had it sitting right on top of a hide in one of my snake's cages, a full 18 inches below the heat light, and when I walked by the cage earlier it was reading 111 degrees! I immiediatly turned the lamp off, but I really find it hard to believe that it was that hot that far below the light. It is only a 75 watt bulb, for goodness sakes. I have no overheating problems when using a red heat bulb of the same wattage in the same cage with the same gauge in the same spot. I was thinking perhaps that because the gauge is black, it absorbs more of the heat and gives an innaccurate reading, given that it is one of the daylight type bulbs. Any thoughts?
