How do I test my projector lamp?


May 8, 2016
Is there a way to test my lamp for a good lamp.
I have 3 lamps someone told me they work.
I do have a problem with my projector. The bulb doesnt light up.
It had problems before with no light up.
No visual defects on bulb.
Is there a way to test them all?
They are very expensive If I throw them out they could be worth $200 a peice. I could keep them if I repair my projector or it could be the bulb.
The projector powers up with all the fans running. Well the bulbs are important.
Please inform me on how to test these. bulbs
