I have an Intellabeam 700 that seemed darker than the other. When I measured the power consumption it turned out that this unit only draws 3,5A (about 600W) at 220V - while the others normally are at 4,5A (around 800W)
I changed the MSR lamps but the behaviour stays the same. Does anybody have an idea what to look for? The power board has screw terminals, so danger of blown contacts is not that high, ... broken ballast, ignitor...? Or is there an undocumented "eco"-mode? :-)
