Quick question… what’s the most powerful high end UVC flashlight and where can I buy it? I heard that the Astrolux MF01S-UVC is good (although perhaps not the most powerful) but I can’t seem to find it for sale anywhere
And for safety… are safety glasses good enough for indoor use? Going to try to blast some mold
Bro, just go to aliexpress and get some of those 38W or 55W with chinese tubes, cheap and good. Fashion some reflector with some aluminum foil or something, it shd be possible with how these gadgets are designed. There are some setups that can do 100W-200W in china, not expensive, just bulky.
So is there a reason why you’d need a portable UVC flashlight? I believe the Mateminco 18S is among the most powerful out there already, and the output i believe still does not compare with a 38W chinese tube, though up close it might more more focused. ie higher candela, but small spot, so if you are gonna be treating say a bathroom or heck even just part of it like the bathtub, good luck.
Any plastic safety glasses or normal prescription glasses is sufficient for UV-C and UV-B wavelengths, it will block. I know this from my reptile hobby.
It is UV-A that is more difficult to block comparatively, but still easy to cut that out.
But seriously, with mold and UVC, only the surface would be treated. You cannot use things like bleach or sodium percabonate? Same surface treatment action and much cheaper/faster too.
I see that you digged up and posted on the Astrolux MF01S thread. Just look at the emitter power, 3.6W input (i believe) and 54mW UVC output. Albeit it’d be pretty focused.
That 54mW output should be believable. Take a look at some UVC LEDs here.
1W input yields 10-15mW UVC

Philips states that around 35% of conversion takes place in its Philips low pressure mercury tubes. So for a 50W, we are talking about at least 15 watts easy, or 15000mW.
Even for a chinese tube (much cheaper on places like Taobao), even at just 20% is gonna be pretty decent UVC output, just ramp up the power.
During 2020 early COVID era, i saw that on TB they were selling things like 100W, 200W, even 500W-1000W setups, with LiFePO4 packs and then some enterprising fella / seller would also use some robotic vaccum cleaner logic/components in it and wah lah….ask tens of thousands for such a setup and big companies would snap it up.
I also saw some portable metal halide type of gadget (few hundred watts bulb, iirc 400W) and they were asking for like 1k for it.

Thanks so much for the advice my friends! I did some reading and it sounds like they generate ozone so I need to figure out a venting plan (: (it’s a basement office with very little air flow)
I’m thinking it would be nice to run a UVC light like once a week for 30 minutes (while I’m not in there obviously)
I’m not skilled enough to build something myself 
The reasons a flashlight occurred to me are 1) it would be cool to zap a hotel room when traveling and 2) who doesn’t want an excuse to get another flashlight?!
Not all of them put out ozone. The advantage of ozone is it gets into places the light can’t see. I got two 15 watt ones from coospider a few years ago. One that puts out ozone and one that doesn’t.
That’s interesting… Amazon reviews on different lights (an unreliable source of information) imply that the presence or absence of ozone is the way to tell a “real” UVC light from a fake one
Big Clive gives us a way to test if a light is really producing UVC. Since there are so many fakes out there.
Get yourself a green banana.
All the Best,
Jeff
The coospider without ozone are currently 253.7 NM. Those with ozone are 185 NM. 254 is the sweet spot as in the most kill potential for living things. I did the banana test with the non ozone bulb a few years ago, I think I left it for more like an hour with checks every 15 minutes, but I put it about 2 ft away from the banana. I’ll have to do the test again with both bulbs.
Use this
The tubes that output both 185nm and 254.3nm generate ozone and also germicidal uvc.
The tubes that output only 254.3nm are germicidal, but do not generate ozone.
Something to do with the type of quartz, which filters the 185nm.
This is great information. Too bad my 365nm UV beast doesn’t kill mold
i would not depend on any UV-C light to kill germs reliably and dependably
[they could hide in shadows, or the power or duration of the light might not be long enough]
in spite of the fact that UV-C is very harsh looking light
On the CBS Evening News yesterday, they were talking about some new type of UV light that kills stuff like Covid-19, but it's safe for human skin and eyes.
The lights are kinda expensive, but they might be in hospitals, airports, and other places in the near future.
Each light is about $200

Wouldn’t it suck b*lls to be a germaphobe right now? I’m the person who eats the chocolate chip cookie that falls on the floor. I just wanna zap some mold.
see i would expect mold to be even LESS afraid than covid or any germ
mold be like ‘light, what light?’
The “Chuck Norris” strain of mold?
That one is the 222nm tech. Actually nothing special about that, only issue is that they gotta make enough of them in the first place so that the prices come down. And also with enough R&D so that we have cheap and good emission sources.
ps. Actually that’s been talked about in 2020 coz of COVID, the stuff has been around even before that.
Just check youtube, there are videos with timestamps. If not timestamps then check the comment dates. :partying_face:
Wow for $200 I’d get them all over the house and let them run when I’m not home
