Need to replace my laser tube and my power supply says 100 watts but the 100 watt tubes that I am looking at are about 57 inches long and mine is about 47 inches long which what I am finding is 80 watts. I am not really worried about the 80 to 100 watts as 80 would be fine for me but is
the 100 watt power supply ok to use on a 80 watt tube
Thanks
