Could you just add a potentiometer in series with the blub and then use it to vary the power going through the bulb?
I'm guessing here, but I've got a funny feeling that I've heard that bulbs have a higher voltage/current requirement when cold then when they are hot simply because the higher resistance when the coil is cold compared to when its hot... that could be why its not working with the lower power on the flash...
Also i'm not sure again... but i thought lowering the power of the flash just reduced the length of the flash, so exposing the sensor for a shorter period... could be wrong again though...
