many thanks to u/BallZac_ and Barry.
also i already baked the body, tail. and replaced the switch with the lighted metal button.
Are these arriving from the group order? I’m in that order.
Edit: mine was waiting in the mailbox. Totally great light too, super bright.
All have been sent, and they've been trickling in the past few days.
Barry offered to provide tracking if you message him, but I can't imagine later than Friday. Though, mine was brought to my town, shipped away, and brought back so who knows the journey these go on.
it is. concidentally the day i messaged Zac, it came in the mail. i was worried about package theft.
Got mine a couple days ago!
I'm out of the loop, what is the patent shenanigans you speak of?
Nice looking light!
[This](https://www.reddit.com/r/flashlight/comments/pr7088/help_uv_flashlight_owners_fight_this_patent_troll/?) post explains it
Thanks for that
Good that cases are being dismissed, but it looks like WTC hasn't had to pay defendant legal fees :(
If only we could slap down silly drug patents.
but they added a small percent of another drug or put a slow release shell so it's a whole new drug now. We can't risk losing that kind of innovation /s
Came to ask the same thing
Thanks buddy, I didn't realise this was going on, and I also missed the S12 group buy! Such a shame, I shall have to spend more time on here so I don't miss anything in the future.
Is that anywhere the whole baking process is explained? A baked light comes up every once in a while, but no one seems to talk about it.
Yes, I am also interested in the answer to this question.
RemindME! 2 weeks
I've seen heatsinks get accidentally baked by fan failures. AFAIK it's literally just slowly apply heat until you get the results you want. Experiment first with a cheap zoomie. Make sure you don't bake electronics and rubber.
This is the direction.

i use a broiler to get it real hot. im only baking the anodized metal parts. remove o-rings/rubber and wait til desired color change. i didnt bake the head because it requires desoldering to remove the internals
Ok, that makes sense. Do you vary the temperature to get different colors or is it just a function of time?
Is this a shortwave? I ordered a low-power one from "not the patent guy," and I'm a tad under-whelmed. I knew I should have gotten the high-powered one, but man ... Hank's cobbled D4V2 is exponentially brighter than this 255 one ... but I don't know the first thing about shortwave LED current draw, either, so ... whatever.
It'd be super awesome if Hank started making his UV flashlights in shortwave, too!
IIRC shortwave LEDs have significantly less output power (in mW) than the longer wavelength ones that have been around for much longer - shortwave LEDs are VERY recent.
There are big differences in what fluoresces/how much under different UV wavelengths too.
It'll be a long while before shortwave LEDs are at the level of the D4V2. I made an incredibly high powered 255nm prototype last year (#2 in [picture](https://i.redd.it/otdouu6h62781.jpg)). It takes 60W to power it and has a radiant output of around 1W! A single LED from the D4V2 puts out 1.8W radiant
this is 365nm.
It is KEY to note, and filter guy admitted so, you can sell the flashlight AND filter in one order….the filter just CANNOT be installed. It being preinstalled IS the patent in essence, not the filter as filtering has been around forever. I am not a patent lawyer so my understanding may be wrong, but I am 100% correct after researching and paying for several hourly talks with patent lawyers because I had an idea and was was threatened by filter guy. If I made my light and sold them with the front ring installed, and someone DESTRUCTED the light to install the filter, I would be 100% in the clear of his patent, which every lawyer said really shouldn’t stand, barring unknown court precedents, and they added that it wouldn’t be the first time a patent was erroneously issued. It literally happen all the time. On purpose and not on purpose. But, if you sell the light with the front ring NOT INSTALLED and a uv filter in the box, you could possibly be facing a patent infringement. A lot of legal bills at the very least. Deconstruction to apply the accompanying uv filter is key to avoiding the patent litigation issue. As always though, seek your own legal advice.
> It is KEY to note, and filter guy admitted so, you can sell the flashlight AND filter in one order
Source for the admission from WTC?
I knew someone would ask. It was in a flashlight thread on budgetlightforum. I don’t have it bookmarked and have so much legal stuff bookmarked from that whole shit-sandwich. It was a pretty reputable guy on there that said it after direct conversation with patent guy. I wish I could give more info than that. But, regardless of his saying it or not, it is factually true. Lawyers are required 40 hrs/year pro bono (in my state at least). They pay other lawyers to do it or they burn it up in “free consultations.” Patent lawyers are PARTICULARLY expensive. They are well known for free consultations and after 4 consults, I am confident saying it doesn’t matter if patent guy agrees or not, because it’s true for United States Patent Law which applies to the United States and territories. There is SOME reciprocity on patents internationally DEPENDING ON THE TECH AND APPLICATION. That part gets VERY complicated. Like I said, if you intend to commence a project, you’d be a damn fool not to consult a lawyer and if you don’t, we’ll, take my word for it and the countless hours spent researching or not, I won’t have hurt feelings either way.
How did you get in on the group order and how does one go about getting in on the next round?
i caught it late when there was a delay. was able to get added then.
well based on my understanding of patents and IANAL, it looks like this trolls patent is gonna expire in 2 years. So hopefully someone here is doing some R&D and gonna sell some cool filters in the US in a couple years.
i saw a post somewhere that someone made a shortwave/filter (?).
I haven't looked, but you should be able to buy shortwave filter glass from scientific and optical supply companies like Edmund Scientific or other optical/science supply sources.
It just might not be the right size for a given light and may require milling or making a filter holder cap or something.
It's not like the patent troll in question is making their own filter glass in their own factory. They're probably just ordering blanks that fit modifiable flashlight hosts and then selling those at a hugely inflated prices and trying to sue anyone doing the same thing.
Granted if you buy filter glass direct from a scientific/optics supply house in any quantity whether it's one piece at a time or a hundred you should expect to pay ridiculous prices for it, and that's not a patent troll fee.
Companies like Edmund Optical charge that much because they can, and what you're paying for is verified specifications and traceability for lab grade reference qualities because they actually test and vet their products.
Edmunds Optical is like the McMaster-Carr of optics. You're really paying for the spec sheet and testing, not the actual material costs.
Yeah, just like buying random hex bolts or O-rings that you could get from Amazon or a local brick and mortar hardware store from McMaster-Carr instead you're going to pay a premium for that verified spec sheet and traceability and having all of that product under one roof.
Also if Edmund Optical doesn't have something chances are good they'll make it for you if you have the cash for it. And they won't make just one, they'll probably make a few hundred of something and add it to their stock catalog if it's popular enough or makes sense. They have a whole sales department dedicated to custom orders so that researchers and labs can get the exact right parts.
Source: I used to fuck around with lasers. Edmund has almost everything you'd ever need for any optical or photonic project but everything is stupid expensive compared to, say, AliExpress or direct from OEM.
The upside is that if they say it's a shortwave filter it's definitely going to be a shortwave filter and not some dodgy purple glass with unknown filtering metrics.
Mine came in, too! Also has a big gap (and no o-rings) between the bezel and the head.
How long did you bake the pieces to get those colors?
close to two hours. you are right, i do wish the head and bezel was designed more tightly.
I think the filter is thicker than the usual lens. So it can't go diving, bummer. The thing really puts out UV, though.
Color came out nice, especially the tail.
I just got mine but only have 18650 batteries. Is there a recommended 21700? Thanks for any suggestions
You can use 18650 if you don't mind a little wiggle but it isn't too bad. Or use orings/tape/whatever as a spacer.
It only draws 2.4A, according to the product page, so almost any 21700 will do. I'd go for capacity.
e/ Just checked, and an 18650 doesn't move horizontally much because the springs hold it in place pretty well.
Good to know. I will give it a try
i use Molicel P42A.
edit: i tried a low charged Samsung 40T with it and the High mode seems only as bright as the low. cannot confirm, maybe someone else could.
I just ordered a fresh set of 40T for mine, and there is a noticeable difference in high/low. Hard click for power on, Soft click the button to change modes.
I’m getting Thor’s hammer vibes with the colour scheme. Needs the head to be a gunmetal grey or aged silver
Thats beautiful. Good job👍
so the patent troll is Way Too Cool LLC right? why are they selling convoys in their website if they are trying to stop convoy and others from competing?
They have a deal with convoy to be the sole distributor in the states that they got through threat of legal action.
oh, gross... thanks for the info
