Hey everyone,
The Massdrop Brass AAA Flashlight was a big hit, and information we gathered from member comments and drop data showed us there was a demand for an upgraded version, so we went back to the same manufacturer and partnered with them to deliver on what the community wanted. To check out the Brass AAA drop discussion - which includes a lot of comments from members who've recently received theirs - click here: https://www.massdrop.com/buy/massdrop-brass-aaa-pocket-flashlight/talk
For this Blue Titanium version of the Massdrop AAA Flashlight, you will see the same top-tier components and the same choice of CREE (brighter) or Nichia (warmer) LED. You will also be getting the same precision machining, tailcap with metal switch, and gold-plated pocket clip that is removable or reversible, and lume ring.
The big difference here is that we've used titanium for the body, so it's lighter and stronger. However, as anyone who has spent a few hours on CandlePowerForums or BudgetLightForum will know, titanium is not a great "heat sink" the way brass is - it is more of an insulator than conductor. That means heat can build up inside the body, overheating the circuitry and shortening the lifespan or even causing failure - to solve that potential issue, we've added a brass ring that dissipates heat, while still maintaining a waterproof seal.
Finally, titanium looks great...but anodized blue titanium looks even better, especially with the golden-colored clip and brass heat sink. The result is a super-handy, high-quality tool with an elevated aesthetic that looks just as good in slacks as in a jeans pocket or tool box.
You will find more information on the Description if you scroll down to the Specs, but we'll be around before and after the launch to answer any questions. Thanks for your interest, we hope you like this one just as much as the original or even more!

Neither titanium nor brass are particularly good materials for flashlights (don't conduct heat away well and there isn't enough mass to think about this as a heat sink) but sure do they look cool. Boring aluminum is better but plebian.
The tiny brass ring won't do squat to dissipate heat.
For occasional use all three will do fine.

Their discription is misleading, it's not so much a ring as it is an exposed pill. There is a brass disc that the led/heat sink pad, and driver are attached to. And the outer edge is exposed instead of making contact with the inner tube. And due to the fact the brass and TI versions of the tool use an electronic switch that contains a miniature battery that is not compatible with 10440 cells, heat buildup really isn't an issue. The copper lights are a great host for a 10440 build, the brass and TI are more suited to be left stock.

Come on Jonas, the brass ring is present on the original titanium lumintop tool. Don't try to sell it like a new feature that massdrop came up with. It's a cool flashlight, and you're offering it in anodized blue titanium. That's great. No need for the false claims.

No claims of reinventing the wheel here, just pointing out that a change from brass to titanium necessitated this feature.

His point is you changed from your second design back to the original design. And claim an original feature as a necessary design change on a new (not) design. Light does look nice though, and they are great functionally. Will probably buy a couple as gifts.

All good points, thanks for the post. I think "occasional use" perfectly describes the use case for this (or most) AAA lights. I've definitely held some monster lights hat get too hot to hold after a couple minutes on turbo mode, but I'd be surprised to see that happen here before the battery ran out. its worth testing, and I will try to make that happen ASAP. Thanks!

This is a good light. I have in copper, aluminum and titanium. I like the TI best but know it's limits. Thanks for making this happen.

I suspect you might be overestimating what being an MD exclusive entails. It is based on something that an unnamed OEM already had, the MD exclusive items might just be a color variation or a different LED choice compared to their normal production.

It's basically the same light. Especially if you are talking about heat dissipation. Massdrop brass on the left, Tool Ti next to it... this drop is basically a Tool Ti with different colors and different programming. All made by Lumintop.
(On that note, a Massdrop exclusive copper light with an electronic switch and a blue or different color pocket clip and/or power switch would be pretty cool.)

Thx for posting the pict.
To clarify to the others I didn't mean I had the unreleased MassDrop "exclusive" just that I had various versions of theLumintop Tool, including one in Ti (not blue anodized).

I'll admit that's pretty funny.
But you missed my point -- I didn't mean I had this "exclusive" (i.e., the blue one) just that I had basically the same light already in titanium (Lumintop Tool).

Levity relieves what my old friend Jerome (you remember him) used to call seriosity, which is what can happen when debaters become so invested in their point that they begin parting their hair around it. I was hep to what you were laying down, large father, but thought it would be safe to let you and the other two hundred people on this thread argue the niceties of exclusives. Shrieking of which, this apparent exclusive's nice.

You mentioned Titanium as an issue about being a heat insulator; does the brass ring actually mitigate or overcome the problem, or am I still at risk of overheating the circuitry?

Yes, that's precisely the purpose of the brass part - the circuit is mounted on it internally and the edges are exposed to 'sink' the heat away and outside the body. I would be very surprised to hear of any heat issues on this light given the AAA power and 110lm output.

NP, glad to help. I will throw a fresh battery in one and run it on High mode for an extended time to confirm and post the findings next week. Have to track down a laser thermometer first...

Good Day, On high mode, does this have a step down to a lower output setting after 3 minutes like the fenix e05? Thank You for the follow up information and your time. Barry Levitt

Hey @barry9 - No, these will run on H for as long as the battery lasts, which is over 40 minutes in my test with Duracell alkaline, which is even a bit longer than the 30 minutes claimed in the specs.

Okay, I ran the test on four sample units, and they all went from about 75* F (room temp) to 85* F within 5 minutes (measured just below the ring), and stayed at that level until the lights began to dim 30-35 minutes later. Hope that helps.

Brass is a great heat sink for flashlights. Of course copper is better.

Yes, copper (especially) and brass can make good heat sinks if there is a fair amount of mass -- but there just isn't enough in a AAA head to make a meaningful difference.
In the 'good old days' when LEDS were less efficient than they are today (therefore generating a lot more heat), pioneers like Wayne Johnson of Electrolumens used to mount the LED to a several ounce chunk of copper as a heat sink and then inserted that assembly inside an aluminum body with metal fins. The copper acted as the sink absorbing the heat generated by the LED. Aluminum, which is a far better conductor of heat, was used in the body and fins to then bring the heat away from the sink. The fins added surface area to promote cooling. It was an ingenious solution to the limitations of the time.
With a small AAA body the choice of materials isn't terribly important, though the exotic materials look really good.

It would be nice to get one of these offered in copper and one in black. I think a black coated brass would look awesome. clips in multiple colors like green red blue and on and on would also be a good drop

I hope in the future you will have one of these made in copper another in black, red, blue, orange, yellow and other colors with an aluminum body. I think they would all sell and not have the downsides of titanium.
