DIY electronic ballast for four 15W fluorescent lamps, just in case someone is interested... (I know, the lamps used in projectors are somewhat harder to drive)

Electronic ballast that drives four 15W fluorescent lamps (ideal for PCB UV exposure)

Can the wattage be changed in these electronic ballasts? I have a AC ballast (Spark Gap Ignition)? It is electronic. The wattage is 250. Can it be changed to 150 or less with some component changes or a pot in place of a sense resistor?
