The pulse size has increased to 8 mm on a 100 watt bulb. Is the tube going bad?
Perhaps, but the result depends on how you measure the beam and what size it was before this happened.
This discussion describes how to measure the beam’s shape and what that means:
Some photos of the targets will help us look over your shoulder and see what you see.
No doubt about it: that tube is defunct.

Thank you very much. Can i use a 150 watt power supply on a 100 watt bulb that peaks at 120
Yes, provided you tune the tube properly to not overcurrent it
The 150 W supply will apply a higher firing voltage to the tube than it should and, as @Colin points out, will require adjustment to prevent applying too much current.
Although your power supply and tube will surely be different, this table (from an Amazon listing) gives some idea of the voltages and currents involved:
as long as i keep under the max amps it should work correct
You will also want to match the voltage settings to your tube. Best to compare what your LPS is capable of (find the model number) and what the tube requires (from the spec sheet)
New 100 watt power suply, new reci 90 watt bulb, new redi controlar, this is my pulse what is wrong?
Far too much power on the paper!
Set the duration and power of the manual pulses in the controller. The details depend on which controller it has, but this is the process on my machine:
After you throttle the beam power down to leave just a scorch on the paper, it should look like a nice round disk with a darker center and lighter perimeter. Show us what it does …
