Titanium 18650?

Firelight2 · 2019-06-27T18:17:34.000Z

FW3A in titanium should hopefully be released soon. That will probably be the best one to get.

You can contact Rey through here(username ReyLight) or on Instagram(https://www.instagram.com/reylight_lan). Pretty sure he has some titanium Dawn 2.1s available.

Are you looking for a multi-emitter light with an e-switch/ramping UI?

I know there are some Titanium/copper Emisar D4’s out there, but you’ll have a hard time finding a new one (especially on a budget). I believe the FW3A will have a Ti version too. Either of these will run off an 18650, and you can get an 18350 tube for the D4.

Between these, the FW3A (actually an FW3T) would be the easiest to source if they are indeed making one. Emisar might make more Ti D4’s at some point because they just released the D4v2.

I'm not actually aware of any fully-titanium 18650 lights.

The Emisar D4Ti was available for a while. It had all titanium except for a copper head.

Amutorch has, I think two or more models with titanium bodies (AT40 and X9), but to my knowledge both have aluminum heads. I feel like I remember another of their lights using the titanium tube from the AT40 with a different head, but I haven't tried to go figure it out.

BlueSwordM · 2019-06-27T19:09:31.000Z

Yeah.

Fully titanium lights would not be a good head.

Since titanium has lower thermal conductivity than aluminium and lower mass per volume than aluminium, it has very poor thermal characteristics.

You’d probably kill the LED on turbo mode without you even feeling it.

I have a fully titanium 18650 light I got from CN Quality Goods years ago. I don’t remember the brand name.

It’s quite small. Looks like a slightly longer DQG Tiny 18650, made entirely out of titanium and with knurling on the head but not the body tube. I plan to mod it someday since unlike the DQG it does not use an integrated driver/star.

fogus · 2019-06-27T20:37:37.000Z

I’d be perfectly fine with a copper head. I do NOT want heat issues. I want slim and durable. Not too pokey (comfy in pocket). Knurling or no knurling. Trit inserts preferred.

I don’t want aluminum though. I have several good aluminum lights, but for my EDC, I want to spring for titanium.

I would like the initial turn on mode to be moonlight, or at least programmable to moonlight.

I’m interested in building my own, but I’ve never done that for a flashlight. I’ve done a lightsaber before though, so that’s somewhat similar, I think.

The Mechforce looked perfect until I realized it was only an 18350. And then there’s the heat issue, but it says it’s on a copper PCB and has a “radiator”, so maybe that’ll help? But I want the more substantial 18650 feel in my hand.

I really do want to be confident that I won’t burn the light out. Whatever protection is available to prevent that: I want it.

Firelight2 · 2019-06-27T20:55:11.000Z

For what you’re looking for I think your best option is to wait for the titanium FW3A. It hit’s all the bases:

copper head with rest of the light titanium
shortcut to moonlight for initial turn-on.
up to 2800 lumens output
Very small and compact for an 18650 light with a great UI.
Looks gorgeous.

It’s not out yet, but I’m keeping fingers crossed that hopefully it’s available in a month or two. Here’s one of the pictures that was posted in the FW3A thread of the prototype:

That looks great besides the copper section, maybe if the knurling on the tail was copper it would look better.

fogus · 2019-06-27T22:09:52.000Z

That looks fantastic as far as specs. I’d prefer a stone washed appearance, but that’s just me.

What do you think the trit options are?

The FW3A has no built-in trit slots on the outside of the body. However, it can use a Carclo 10507 optic, and I know that Neal is selling such optics with 3 trits pre-installed for $30 each.

Some people have also modded the tailcaps in their aluminum FW3As to add room for a trit. That’s probably the only other place to put one.

If bezel trits aren’t bright enough for you, Lexel has prototyped an aux led board. When installed, you get a colorful glow behind the bezel when the light is off from 12 tiny colored LEDs. These are typically much brighter than any trit.

The copper section is the head. It’s a single piece that contains the shelf for the star (the board with the LEDs on it), and the driver.

Titanium is a relatively poor conductor of heat. It’s common for titanium hot-rod lights like this one to use copper for the section with the star on it for just this reason. Copper is an excellent conductor of heat and helps remove the heat from the LEDs.

The FW3A is quite a small light for producing around 3,000 lumens. It is 25mm wide at the head and 92mm long. It’s one of the most compact available 18650 lights.

BOO5TED · 2019-06-27T22:21:01.000Z

I get that, it just looks out of place with that being the only copper part of the light. Rear tail section or possibly a copper pocket clip would make it more visually appealing to me.

fogus · 2019-06-27T22:29:48.000Z

That LED idea sounds cool. As long as it doesn’t run down the battery too quickly and isn’t so bright I can’t sleep at night… Do you have a link to it? How can I learn more?

emarkd · 2019-06-27T23:21:29.000Z

There are titanium lights out there with copper heads (for heat) and matching copper tail (for looks). Here’s one of mine, a FocusWorks Eryx F1.

I also have the ReyLight Dawn already mentioned, solid titanium. Its a great light, but it does not shed heat well. In fact one fateful evening I wasn’t paying close enough attention to how hot the head was getting that it melted its own polycarb optic. Luckily its a $2 part…

That’s not to discourage you from the ReyLight, its a great flashlight. But it does require some careful handling. Its not one I’d hand to my kids…

BOO5TED · 2019-06-27T23:26:44.000Z

I’ve wanted a Dawn for a while but interested in the new Gemini coming out more.

fogus · 2019-06-28T01:16:00.000Z

I’m going to have a hard time justifying going much over $300, but I’m glad to see options above that.

For the FW3A, what price range should I expect?

Waiting a few months is no big deal for this purchase. I’m looking for a light that really hits everything I’m lacking in the S41S, so I’m willing to wait for that.

AIRAYLAND TC8 Titanium XP-G3 18650 Flashlights

Just saw this and thought it looked pretty cool… [image] … [image] 18650 powered, XP-G3, metal “1288” tail switch, USB charging, Titanium. Must have been a lower price recently, when google’d it still shows ” US$31.50” Here’s some more eye candy: [image] [image] [image] I don’t know much about XP-G3 though. Better than XP-G2 I suppose?

fogus · 2019-06-28T01:41:16.000Z

The price on that makes me a tad nervous. I’d expect to pay at least $150, but I won’t say no to keeping my money. Not a huge fan of the design. I’ll be watching to see what people say about reliability for this one.

I searched for this but did not find it.

Also, that FocusWorks Eryx F1 looks fantastic. A bit out of my price range. I’d take a simpler stone washed exterior to save money if possible (hoping to keep below US$300).
