[May 8] Olight I3 UV "Free" i.e. $10

What do you mean? Referring to the twist operation?

You see a lot of false positives using it around the house.

I love my little blue i3s.

UV lights just aren’t for me, I guess?

Chris

Haha, now I get it.

Better to know than not, right?

Hey… I’m not adverse to masturbation, but I’m not doing it all over my place.

I also don’t currently have any pet scorpions and looking at paper money with the i3UV gets old after 30 seconds.

Chris

I was thinking more in terms of outside the house, like hotels, which always creep me out wondering…

I can see why UV can be an auxiliary LED on other flashlights. It’s definitely not a priority and I’m not willing to pay much for it.

Bear in mind that sensitive persons need to wear UV glasses when using such flashlights in their homes/hotel rooms. A lot of light gets reflected and can hurt the eyes. Feels like snow blindness.

For me I use them to load up the glow on my fishing jigs/flashers. Works very well. 395nm is good enough although I do also use 365nm for curing windshield ding resin. I use it to attach tritium onto stuff as well since it dries optically clear. A 395nm wouldn’t work well for curing purposes. My other UV is the Convoy S2 UV using LG 365UV and ZWB filter 18650 battery. My box of squid jigs light up like a Christmas tree!

I would add that sensitive persons should not use these lights in hotels (etc) at all.
It will keep you awake at night, puzzling “how did that footprint get on the ceiling”.
Kitchen, shower, and toilets will be pretty clean. It’s the places you expect the least that ….

Thanks for the heads up.
Ordered one free i3 UV light just now.
Shipping was $5 for me, in the US.

OK, I have a couple of the I3 UV lights on the way, looking forward to some fun night time explorations in the yard with my son. I will defiantly make sure I hide them if we visit a hotel to shield him from long term emotional damage :slight_smile:

Now I just need some recommendations for a good set of 395nm UV blocking safety glasses, preferably that can be worn over glasses.

Hi, thanks for the heads up. I see a lot of people mentioning eye protection. While I don’t plan on shining this in my eyes is it really powerful enough to need PPE?

Absolutely, yes. There are geocachers that take pictures from illuminated objects so they don’t have to stare at them for longer. So, even outside where reflections are a minor problem sensitive persons have problems.

Another Olight for 5 five bux (almost bought the C-note Worrier, but
You can get a cupla nice budget lights for more Lumens).

same… my wallet is not very happy with you… lol

UV is dangerous, but I wear glasses… they block UV

I bought the UV light so I can make trits glow when I take a photo during the day

I already know that the 395 UV is not effective to show the red line on USA $100… but I did not buy a tiny aaa UV to test currency… nor do I plan to get that close to a scorpion… if I did I would buy a serious UV light, instead of a (dangerous) toy…

I bet people will turn the light on and look at it to see if its working… can you say, burned retina? Just dont use UV without eye protection…

gotta love “free”… (my wallet says $5 is not free)… lol

more info about serious use 365 UV lights here

Convoy makes a good 18650 model.
Jetbeam makes a good AAA model

I didn’t need it but figured it would be fun for trits and glow. $10 “free”.

In the end I placed an order too.

I have a “blacklight” CFL bulb of unknown wavelength and yes the light from it is quite disorienting. It practically never gets used, and even when turned on it’s never for long.

I don’t know the transmission rate or wavelength cutoff for UV protection in eyeglasses. Lately they sell lenses with blue light blocking polymers, maybe in the range of 420nm.

For PPE, something like the Uvex Skyper with SCT Orange would be an option. It might fit over some eyeglasses and seems to have a cutoff at 540nm. It seems popular with people who want to block blue light from electronic displays and is affordable. https://www.amazon.ca/Uvex-S1933X-Eyewear-SCT-Orange-Anti-Fog/dp/B000USRG90

My Uvex Blaze 3 came with three sets of glasses (rainbow polarized, yellow, and clear), all with sufficient UV protection. I use them for running (polarized) and when working with UV light (clear) and I never noticed impairment due to the light. See if you find them at least with the clear glasses option. But I guess all brand glasses labeled “100% UV protection” will do.

Seems reinbow/polarized is hard to find in the US/CA, but grey is available:

“–100% protection against ultraviolet rays. -mirror lens technology. -soft padding. polarized lenses that prevent unwanted reflections. -includes carrying case. lenses included:-lens reflex smoke polarized (polavision) (s3). -transparent lens (s0). -orange lens (s1). ”

Thanks phouton, I was looking at some of the Uvex safety glasses. The form factor looks good and I am hoping to find some that are clear. I was thinking of Uvex (Honeywell) or 3M mainly as brands that would have done accurate testing and manufacturing.

My glasses also have a UV coating but I can’t really confirm how well they will block the UV and also if the coating may have deteriorated or scratched off in places. A dedicated set of UV glasses seems like a good option for me.

I have a couple friends who work in UV environments and will ask them for advice. If I find anything at a good price I will pass it along.

Polycarbonate lenses block 100 percent UV

my Jetbeam UV light
unprotected, polycarbonate, Laser Retinologist provided UV blockers

using UV to find the warm LEDs in a bulk bin of Quark heads

Unheard Maybe some of the clear options make more sense for most people. I wish the transmission spectrum or at least cutoff wavelength would be mentioned more prominently. I found a few mentions of these for Uvex Skyper with SCT Orange which is why I mentioned it.

Ilumenati When your order arrives you can qualitatively test the 395nm transmission through your glasses. (Not by point into your eyes obviously :sunglasses: )

jon_slider Nice pics! Interesting that the 365nm UV LED still emits a fair bit of visible light. It would be nice to see the same lighting conditions with and without the polycarbonate glasses filter, though I wonder what can be concluded without a spectrometer. Could try with fluorescent material in the background. Curious why you got a 395nm UV if you already have a 365nm.
