I would recommend you not try to calculate this, but rather measure it
directly. Use color-changing paint or crayon and measure the temperature
of the tube seals under those conditions. Start off with low power and
work up to the point where the tube manufacturer's maximum
recommendations are just barely met.
A calculation is only a guess because there are too many unknown
variables. The paint or crayon will tell you exactly what you want to know.
