How hot is a 50w heat lamp light bulb in Fahrenheit?

I use a 75 watt heat lamp in 36" habitat. at the end i use it on, it is about 80-82 degrees. it depends on how far away the bulb is and how the temp. is naturally. so don't place it close enough to get touched or burned by whatever your warming not burning. Hope this helps a bit. not a professional. Just experienced this much.
