Of your light causes the substrate to be that hot you need to find a way to keep heat in without using the bulb at full strength. Covering 1/3 or 3/4 of your screen top will help to hold heat and humidity in so your bulb doesn't have to be up so high. Do you use a lamp with a dimmer switch? If not you should. You can adjust the amount of light and heat prduced by the bulb. Also when using lights I always recommend using some kind of plant cover for shade and security. I've never had my substrate be hot to the touch while using heat lamps.
The bulb is a 60 watt. I know this is a bit over the maximum but it was the only one I could find at the pet shop, and without it the enclosure is dangerously cool. I weighed out the pros and cons. As soon as I find a 50 watt I'll use that. I use a full spectrum blue bulb during the day and a red bulb at night. It does have a dimmer. The substrate wasn't hot. It was just warm. I don't know how far the heat penetrated.
