I have been a Firefighter for 26 years and have been to several structure fires where heat lamps were to blame.
If for some reason heat lamp is required I would aggee that finding a solid/permanent way to mount the lamp would be crucial. trusting the clamp would be a bad idea
Some people will put a screw in so the clamp cannot slide off.. like in this picture

If I had no other choice I would go a bit farther and find a way to attach the clamp to the board so that it could only be moved or removed with a screw driver
I have also heard that if you open your coop and a gust of super cold air hits the lamp the bulb can shatter.
I wonder if a
panel style heater like this one would work fit your needs. They can be free standing, mounted to the wall, or hung...
