As I know automotive HID lamp overdriven to 50W puts out 5300 lumens, but I can't find anywhere how many lumens has same lamp underdriven to 25W...

Do you know?

Cheers,

Approx. possible range 1700 to 2000 lumens. 25 watts underdriven using a 35 watt standard bulb will result in a less than normal life span. 28-30 watts will give better bulb life results.
