This thing is pretty slick all-in-all... I know a couple UV-addicts over on Reddit who will be quite interested in it! Nice work as always! Love your camera work and the demonstrations!
Great seeing you here TK! I REALLY wanted to put Anduril on this. I even think I contacted you at one point for help. I tried 3 different manufacturers and none of them knew how to work with ATTINY chips. Even offered to have the firmware part written for them. They didn't have the equipment to flash it. Turns out Atmel isn't really used in China. They don't even have Chinese datasheets!
@@Raymond-Wu As is, I'm not sure I would have been able to help. Anduril would need major changes to work with 3 buttons, and I haven't been able to work much due to a broken spine. But it's really cool that you made a wide-spectrum UV light. It's like high CRI, but for the invisible spectrum. ❤
@@ToyKeeper Ah. Hope you have a smooth recovery! I don't remember who offhand but someone on BLF offered to refactor Anduril to work with 3 channels. I think wolfgirl if I remember correctly? Never got to use her help though unfortunately. Thanks for the compliments too! Feels great to cap a 3 year long project with a video like this 😀
It's awesome! I love searching for cool rocks. I'll have to get one of these. :) I found out about you and your product Raymond from your post on Evan's circle.=D
Wow, I'm quite amazed by these minerals, how they're glowing only in the specific uv wavelength. And you're presumably able to find these just laying there on the ground? That's cool, I might try to try this myself in the future, as a way to make night walks with flashlights more interesting 😁
@@tomallo99 FWOD creator here. You can definitely find rocks and minerals that fluoresce laying around. These reactions aren't something that people can look for without a specific uv frequency as you stated. There have been incidences where it was turned into concrete! Just look up "fluorescent concrete franklin nj". It's also very fun to get a good deal at gem and mineral shows because the piece they're selling doesn't look pretty in white light but gorgeous under uv. Many times the dealer didn't even know!
Sorry my pricing didn't meet your expectations. I always try to be on the bleeding edge of technology with my lights. For example, there's not a single mention of the 255nm LED I used anywhere on the internet outside of this review. It's not publicly available for sale yet but represents the latest improvements in 255nm tech. Costs $$$ though! I leave it to Chinese manufacturers to come up with something more affordable.
@@ericcarabetta1161 I appreciate the compliment! It's been 3 years in the making so it warms my heart knowing that other people think that. Makes the effort worth it! Even if you don't end up getting it for Christmas feel free to ask me any uv related questions.
Creator of the FWOD here. Most UV adhesives will do fine with just 365nm. However, there are some high end ones such as my favorite Loctite 349 Impruv that recommends a cure at 255nm (? can't remember exact wavelength) for full strength. Check the datasheet of whatever UV adhesive you're using
There is a less expensive mineral light on Amazon from Wondsunson that has three wavelengths (395, 365 and 254) for about 80 bucks. It does not have the UV-B 310 nm wavelength, however, and it's not as bright. It also has ZWB filters, so probably isn't as good as the dichroic lens. However, I can attest that it has very nice build quality, and does the job. It's USB-C rechargeable with a built-in 18650 battery. Even given all that, it still may be attractive to quite a lot of people at less than 1/4 the price.
Creator the the FWOD here. If it works it works! More power to you. Plus you'll have saved a lot of money. The light you're talking about is more of a gem inspection light - sharpie marker sized with shortwave and longwave emitters on opposite sides. You can't put both of them on a single specimen like I did in my prototype video linked in the description. Plus, as you can imagine, the LEDs used in that light are considerably weaker as well as the filter not being as good as you stated. The LEDs they're using cost ~$2-3 wholesale while mine are $20. For those that are considering the Wondsunson light I recommend getting it directly from China! You can save an additional $10-20 as the light is only $60-70 from other sites
@@fwiffo Yup, I never bother with the race to the bottom. Chinese manufacturers will beat me 10 out of 10 times. I like innovating in this space and thankfully I do have customers willing to support me to the point where I'm able to continue doing this! Even if you don't purchase a light feel free to reach out if you ever have any uv related questions
Do you plan to review the Lume driver from Hank? I got a boost driver in D4K and I like it but I could use more low and top end. I'm curious if it's worth doing a driver swap.
I'll throw out that chlorophyll glows under UV, so you can use UV to help find fresher groceries. Also, something's been bugging me. How dangerous is UV-A? I'd heard the warnings about B and C, and thought they also applied in a lesser fashion to A, but I don't really see warnings accompanying 365nm lights.
Creator of the FWOD here. Haven't heard of people using a uv light to find fresher groceries. I know people do photograph plants under uv lights as they all fluoresce in different ways like the minerals showcased in the video. I'm not immediately sure if that'd be beneficial over visual inspection in white light. As for UVA safety, it's most of the uv light that makes it to the surface of the Earth, albeit a potentially stronger source as the flashlight focuses the beam. Still follow the safety tips in the video!
@Raymond-Wu Awesome, thanks so much for the info! I often feel like newbie safety is forgotten about all too often in the flashlight hobby. You're awesome for being willing to answer those questions here in the comments. With the plants, I've found that some like cilantro often will glow at different levels of intensity at the store. That allows (at least in my mind 😁) the ability to see who's more alive among the bin.
@@OddBall1997UVC light has sterilization properties so you could disinfect the groceries too 😂 And UVB is used as a grow light. Not that this light was built with those purposes in mind!
@@Raymond-Wu Haha! I can almost see the old fashioned appliance ad: Tired of wilted greens and tasteless produce? The FWOD Grow-Fresh is here to revolutionize your kitchen. From growth to freshness to cleaning, this innovative light lets you grow fresh herbs and vegetables right on your countertop, all year round!
Interesting, I haven't heard of that use case. I know UV causes many flowers to flouresce in interesting patterns that are used to attract pollinating insects. Also yes just to add, a powerful UVA light still requires eye protection to use, even if it's not ionizing radiation like UVC.
I’m honestly amazed those tiny emitters can light up rocks feet away, I’ve seen some really shitty short wave/ long wave tube emitter black lights that can only be used for personal viewing or photography.
I tried ordering one, but the website keeps giving me errors for the shopping cart (because I keep all my cookies disabled), so I gave up on it, I'll buy it when it comes on Amazon.

Hi Ethan I wanna open a flashlight retail store here in my city whereas power outages happen 6-8 hours daily. Can you help me think about the name what should I give that is affiliate with 'lumen'. I don't want to use "lumencraft".
Creator of the FWOD here. The hobby of fluorescent minerals has always dealt with these uv wavelengths. Caution should always be exercised and Luxwad did a great job with that portion of the video. If you do decide to get a more affordable UVC light please reference the safety tips in this video!
The risks are somewhat overstated - the precautions in the video are sufficient. 10 minutes in the summer sun is much more dangerous than some occasional reflected UV-C exposure from a light like this. Which is why eye and skin protection is always recommended any time you are in the sun. The biggest risk is your 8-year-old thinking it's a regular flashlight, and staring into the thing wondering why it's not working. I wouldn't want to deal with a young child with welder's flash. However, it's a special-purpose device, not really a novelty light and not useful for most people.
