ANOTHER 2nd channel video

Note that one of the newer developments of LED lighting for video production is the use of "remote phosphor" LED lights. The LED's are UV, and the UV light hits a phosphor that converts that UV to visible spectrum. Bonus is that the phosphor is similar to the phosphor used in flo[u]rescent lighting. Also bonus is you get much more full-spectrum than what was produce-able from a cluster of monochromatic (RGBWetc) LED's directly illuminating the scene. Also bonus is that it's not a lot of little light sources giving weird shadows, it's a larger phosphor-driven light tube or whatever throwing more even lighting.

I don't generally caption videos for the 2nd channel. Without a script it's pretty time-consuming, so unless it's meant to tie-in with a main channel video, it's up to auto-generated captions, I'm afraid.

Technology Connections

Hiya! How long does it usually take you to caption your videos? I've noticed your recent ones have no captions. :(

This video from Applied Science seems strangely relevant fo how recently it was posted https://youtu.be/vDsjHQPjMVI

Congratulations, you got a UV (mini) flashlight, a UV test card, and they even threw in some stylish prop glasses! Hopefully you can find a use for all those things (other than the advertised use :-) ). Ewen

I suspected that too, but I visited their website and the company offers prescription versions of the lenses.

The clear glasses block UV-A. The LED emits UV-A. The card responds to UV-A. The product isn't a hoax, it's just misbranded, possibly for Chinese to English translation reasons. Mystery solved!

I'll just throw this out there; some flavors of the lenovo yoga laptops have oled displays. Starting around 800 used, they're not financially realistic for everyone, although they're good laptops in their own right and, well, they exist. I've yet to see a consumer level oled standalone display. Oled + darkmode will cut blue light to virtually nil.

Can u go outside and use the sun to shine through glassed to a white paper with both?thx for video

Seeing your YT in the background makes me want to ask: do you have any suggestions of YTers to follow other than yourself? Obviously techmoan, LGR, vwestlife, bigclive, etc. - any others?

I'd be a little careful here. While I agree that I think this is a borderline scam, you do show the company name on the test card. They may push back regarding your negative comments

It’s just a black light LED. Nothing inherently dangerous about it until you get more powerful diodes.

Sean Hearrell

That's a good suggestion. I don't trust them full stop but with this sort of product (that I'm already skeptical of from the start) I don't have a clue what might be worthy of praise.

Technology Connections

I think I heard you say that Amazon reviews are something you trust. You may want to run the product page through fakespot.com

I will certainly do so if it does not improve, however I only experience symptoms when I've spent 4+ hours in front of a backlit screen (and honestly it's not very bad). It doesn't help that increasingly I'm using enormous screens that fill an inordinate amount of my visual field because they're just better for doing a lot of my work.

Don't attempt to diagnose and treat your own eyestrain. Please see an optometrist and tell him/her your symptoms. If it's not garden variety presbyopia, whatever is going on you want to get it figured out now rather than later.

Blair Witch Connections!!! I can see the benefit of the glasses for holiday makers and equator dwellers if you want eye protection without making the world dull. However if they’re marketed specifically for monitor eye strain then they’ve either massively misunderstood or it’s a scam.

I have a a UV torch and it gives off a dull blue light like the UV fluorescent tubes at a disco. Indeed it fluorescence's when shining on white paper, cotton, etc. That one very likely has a blue LED in addition to UV. Try shinning on some bank notes to see if any hidden text/images light up. Most currency bank notes such as Euro notes have text or images that light up under UV light, but not under regular light.

What I think you've discovered here, other than a horribly misleading and mislabeled product, is that glass blocks some UV light. Based on my google searches of the last 5 minutes, most glass will block pretty much all UV-B and UV-C light, while allowing most UV-A. When you shined it through the glass light bulb, it was blocking some of the UV light. As for the glasses, as others have pointed out, they seem to have a UV blocking coating on them.

Wouldn't it be kind of dangerous to have a uv laser pointer? Feels like that shouldn't be something thrown into a glasses purchase to convince you they're working
