I got flashed tonight.

Thanks for posting this. I just got a good scare tonight: my Lincoln Viking 3350 started to occasionally shut off a second after striking an arc. After the 3rd time I figured it wasn't a fluke. I was worried I'd get the dreaded arc eye.

Kinda annoyed; its only about 3 months old and I'd guess less than 2 hours of total arc time. Reproduces on the bench out of the helmet:

You should send your video to the manufacturers/sales support email , they might just send you a new insert in the mail.

Right! Most plastics are not UV transparent; that's why CO2 lasers cut clear acrylic so nicely ;-)
My blue diode laser wont touch clear at all, but can do black and transparent orange. Transparent orange blocks blue, you see!

Yep, I did send the video to the case manager.

Prior to sending the video they already planned on sending a new lens once they confirmed its under warranty. Pretty good service so far!

A quick follow-up on my particular issue: I called to check on status after a week had passed by without any updates/shipping info/etc... I was then told that there was a 2-3 week back-order for the lens. I asked if they had complete helmets in stock which I could buy at a discount in the meantime since this was my only lid. They offered to send me the whole helmet instead of just the lens. Good customer service. Showed up 2-3 days after I called them.

But more importantly: the new lens showed the same behavior with the flashlight test on the bench. I dug a bit deeper: out of 7 LED flashlights, all caused the lens problem except for one of my MagLights (the lenses worked 100% of the time with this one flashlight). All the flashlights I tested with have COB LEDs so not sure what the difference would be. Anyway: LED flashlights probably aren't a good way to test lenses.

When using the sun (UV/IR) or a TV remote control (IR): the new AND old lens tested perfectly fine. I tried a few arcs with the old lens and the problem didn't reproduce yet. Weird. But I'll run the old lens for a bit to see if the problems I originally experienced was a fluke or not.

LEDs are not a continous spectrum. Sun and arc are. Lots of peaks add together to get sorta okay-ish. Your eyeballs arent that picky, but the sensor might be narrow band.

The sensors work by detecting heat, not visible light... Which is why the IR remote works effectively.

Another issue here is that some flashlights have smart controllers.
My Mag-Lite XL200 that is always on my belt has a circuit that actually pulses the LED faster than the eye can see.
They use it to get high LED current pulses for high light output while controlling heat, but also to help with battery life.
If I try to use it for additional lighting with cell-phone photos then the photos have light and dark bands thru-out.
