Question about InFocus Replacement Lamp Projector Lamp For X1 Projector&Screenplay 4800 [ SP-LAMP-009
The Infocus X1 projector gives an indication that the "lamp is not firing after 5 attempts". Before I spend the money on a new lamp, can I check the Ohms of the lamp (I get infinite ohms) or can I check the voltage to the lamp (approx. 129VAC at the connector) to confirm that it is the lamp? It is alot of money to buy the lamp if the unit is at fault. In other words, is there a way I can confirm it is a lamp fault, or, could it just be the projector itself?
1. Projector lamps use customized ballasts that ignite the lamp
by charging it with a higher voltage in the ignition phase and then
dropping down to a lower running voltage once the circuit is created.
2. Projector lamps CANNOT be tested with an AMP or OHM meter. Projector lamps function by igniting ultra-high pressurized mercury vapor across an ARC tube. At the point where the mercury vapor resides there is no conductive electrical material and therefore testing a projector lamp with an AMP or OHM will not work.

Projector lamps can be tested using automotive HID(xenon) ballast although it won't tell you much because even if it lights up it doesn't mean that projector is capable to ignite it also. Old lamps require much higher voltage to ignite and draws more current.
