Schneider Xenotar 150mm f2.8 Lens Question

[ColonelKurtz]

get a UV LED flashlight, you can clear it in a few weeks that way.

Any particular one you can recommend? Seems like it make sense to find one with lower lumens to not end up buying a ton of batteries... Guess I'll have to take a guess, unless you have some experience in this dept.

a ton of batteries...

Rechargeable batteries or a power supply

Why use a flashlight? IKEA sells an LED work light JANSJÖ that has been reported to put out enough UV to clear yellowed lenses. Plugs into the wall, inexpensive.

Jansjo it is... Tomorrow mid day when Ikea is empty lol. Now I'm thinking a UV LED reptile light will be the quickest way, as those bulbs emit very strong UV, made for reptiles and plant growth.

Also, if anyone has a lead on a push-on rear cap for this lens (63.5mm) please let me know... I don't see anything online anywhere... Thanks
UPDATE: Found.

Plus one for the JANSJÖ. I've used it on half a dozen yellow lenses, works great.
Puts out a lot of UV and almost no heat. Costs less than $20.

Or if you shoot black and white, just leave it.
