EVW bulb

[tballphoto]

what is the correct Lampe ASA code EVW 82 volt 250 watt quartz halogen lamp in dichroic reflector?

"common" ones are running 13-18$ each, the OFFICIAL Beseler EVW replacement bulb runs 115.00$ with a 3 week waiting peroid.. and something called the ESJ bulb that is supposedly the same thing but for only 25$.

im running on what is supposed to be the second replacement bulb the previous owner put in my dual dichro s and id like to get some replacements because I have a feeling its on the end of its life,

EVW is correct.
There are lots of alternative manufacturers. The more reliable and longer lasting ones tend to be more expensive.

Buy extras.

The official Beseler bulb isn't any better. I've stockpiled a few vintage GE bulbs new old stock.
One other thing, keep the terminals clean. I always check the lamp with a multi meter.
If an university instructor has a Beseler manual, with a part number, sends a request to the purchasing department, purchasing orders using the Beseler number $$$$$.
It's OK by me keeps, Beseler healthy
