150W-290W Mercury Short-Arc Xenonics XN-01 Mod
I'm proud to show my searchlight build!!
It's 200W 0.9 mercury burner inside, driven at 150W
Custom machined adapter, burner glued with cement(alebastr)
Using 150 C/00 ballast with 25kV ignition voltage.
Mosfet switch used to isolate negative wire, just to be sure that there is no current flow ( parasitic or whatever)
DC to DC converter, from 12V DC to 400V DC(actually 20kHZ 400V AC rectified with 1000V UF diode and 1000uF 400V cap)
Small dc to dc converter from 12 to 6V used to power up the optocoupler on the ballast, with the 1.2 kOm resistor.
