So yesterday, finally, a brand new Ushio UXL-75XE lamp arrived at my office. I wanted to test it on my Gen2 (G2-20) MB with use of the bulb adapters made by Parker VH and make a comparison beamshot between this lamp and the official "Ushio" MB lamp.
First of all, let's see the visual difference between the lamps: in the below picture you find all the lamps that you can currently use on your MB:

1) Older "ARC" lamp. Cylindrical arc tube, bad optical displacement.
2) Newer (current) "Ushio" lamp. Small round arc tube, better optical displacement. Peak Beam changed design from ARC to Ushio in the Gen3 lights, and asked Ushio to custom produce a lamp for them, based on the UXL-75XE.
3) Standard UXL-75XE lamp, with the Parker VH bulb adapters installed.
Notice how the round bulb in the UXL is much bigger than in the "Ushio" MB lamp!!!
Technically speaking, a bigger bulb like that would create even less arc displacement (better). That's why I wanted to test it on the MB and make a comparison test.
BUT:
I installed the UXL on my MB and... it light up once, then I shut it off, and it didn't light up ANYMORE...!!! It only makes a spark in the lamp base but that's it... does not work!!!!
Why???????
I am using, on the "Ushio" MB lamp, a 14,4 V battery pack (LiPo 4s), and it works fine... is it too much for the standard Ushio UXL-75XE lamp which is rated at 12,5 V?
Did I already "brake" the lamp?
Bottom line is: the UXL-75XE on my MB worked ONCE... now it does not. Any thoughts?
