I bought 3 Bowens Esprit Gemini 750+ flash heads last year & very satisfied with them, but Ive been recently looking at getting spare flash tube for them, but all I can findon line is info on models up to 400 which quote tube no 2030 or 2032 (from memory) can anyone tell me what is the replacement for the 750.
Also can anyone explain how the same replacement can be used for different wattages ie 200/400.

There are different ways to put multiple wattages through bulbs.
One is too have multiple filaments or multiple gas chambers (neon/argon etc.. not that other thing) in the bulb.
If you only fire one filament/chamber, you get that amount of light.
Things like this you would see multiple contact points on the bulbs and equipment.

More commonly, having a potentiometer or rheostat to control how much power goes through the bulb.

Most bulbs that would do 400w as a fixed wattage could also do 200 watts, they would just be half as bright. (and possibly last twice as long and generate a lot less heat.)

Good luck finding bulbs!
