Hookah coals burn too hot. What to do?

Yeaux asked: Everytime i use my hookah ( 14in Mya brand )
the coals seem to be burning a little too hot.
Ive tried Golden Coals (natural quick light),
SIlver Coals (quick light)
King Coal (Large quick lights)
and 3 Kings (quick light)
and they all burn too hot, and end up burning the tobacco within 5 minutes of the bowl [...]
