Hello,
We have 3W xenon flashlamps which flash once every 800ms
The flash looks to be quite long, but in fact the tube current flows literally for just ~200us for each flash.
Recently, we doubled the trigger voltage (making it correspond to that required by the tube) and the light output appears to have gone down by 40%.
However, i suspect that its our light measuring equipment.
The higher trigger voltage, i believe is making the flash of higher current , but shorter lasting, and i believe our light measuring equipment misses the shorter duration flash.....and gives a low reading.
What equipment do you recomend for measuring the light output in our case here?
I do not have access to the darkroom till the engineer gets back and thats two weeks, -so i cannot even say what equipment we have.
