It’s not the birthdays TL, it’s the mileage in between. We don’t need time travel, we need genetic rewind/replay.

I rewired the DBC-05 Triple XHP-50.2 with Turnigy 18ga leads. This was not easy, but I was hoping it’d be worth it. The previous leads were 20ga Teflon coated wires.

While I was at it I enabled moon mode so now I have 7 modes. Smile

I charged up my somewhat beat up Basen’s and got…

0.06A for 47.61 Lumens
0.15A for 147.66
0.47A for 431.94
1.41A for 1235.1
5.98A for 3881.25
12.07A for 7032
21.74A for 10,764

More amps, but a bit less output. Hmmmm.

So I tried a pair of Sony VTC6 right off the charger…

22.78A for 10,936.5 lumens

Then I charged up a brand new pair of LiitoKala 26650’s…

23.12A for 11,488.5 lumens after having my clamp meter on AC for a bit before I figured that one out…

So, again fresh, right off the charger, the LiitoKala’s…

Start 11,523 lumens
30 sec 10,660.5
60 sec 9,004.5 and the cells were down to 75%, the big chunk of copper was HOT!

Larry Niven wrote an anthology called The Long ARM of Gil Hamilton, mainly about what becomes euphemistically called organlegging (the bootlegging of organs). Set after transplant surgery(including the brain) is commonplace but before organ cloning becomes a viable option there’s a black market in organs(already true) and kidnapping for organs rather than ransom is the rule. In one of the tales our hero is hot on the trail of one such wealthy body snatcher. In another a young man convicted of speeding gets the death penalty with the state collecting his bits as compensation for all the trouble he has (or might yet) caused.

Maybe you could mount that light to a tripod and put a remote trigger on it and use it as a camera flash. Lol

That was a fun book. I enjoyed some of the ideas about how to use a phantom arm… like feeling / fixing things inside enclosed spaces, or when he was bound and unable to move at one point so he lured his captor close and reached into his chest to grab the guy’s heart.

Niven had a lot of fun books, and that wasn’t one of the more well-known ones, but it stood out since it was so different than the rest.

Kind of like Dale’s custom build here… it’s one of a kind. And if you’re not careful around it, it may well give someone a heart attack. Smile

Rethinking this one, I happen to have 3 of the XHP-70.2 N4 5700K in hand, mounted on SinkPAD’s. I checked how they would fit this reflector and found I have some white plastic cover pieces that would protect the substrate of the emitter and allow the dome only to show in the reflector. So, since the 20mm SinkPAD has to be ground down on one side, I’d have to remove these emitters from the MCPCB and do the grinding, then re-flow the emitters and mount them in the copper pill. Would it be worth it? Well, that’s the question of the day.

I recently rebuilt a friends SupFire M6, removing the 70’s I’d put in it earlier and swapping in the new 70.2’s. It now makes 13,558.5 lumens from 3 emitters. It uses a TK61 battery carrier with a custom tube made by MRsDNF, I didn’t pull the brass rods out of the carrier as I’ve done in the past, but maybe it’d do even more with 18ga wire there? At any rate, since my light here is a 2S tube I might see more lumens from a pair of Efest 20700 or the Sanyo NCR20700A.

Not a terrible amount of work, but is it worth it?

Ok, so I figured if I’m going to re-do this build I may as well address the reflector while I’m at it so I just ordered the other triple reflector that they listed after I got the one that’s in it. Also ordered 3 new XHP-70.2 emitters in P2 5700K tint. I’ll have to enlarge my reflector opening as this new one is 65.5mm diameter. It’s also taller, but that shouldn’t be a problem as my bezel has some shift room while maintaining fit and finish.
I went ahead and used DHL so perhaps it won’t be long getting these in. Wink

Edit: Also found and ordered a pair of iJoy 21700’s that are supposed to be capable of a 24A continuous discharge with a 40A pulse. We’ll see…

It’s an addiction, always looking for the ceiling. Sometimes I wish I could be more happy with a beautifully crafted light that performed decently and not always have to have “more”. There are a few lights in my collection that aren’t pushed to their limits, but it’s very few.

Like the Emisar D1, I really liked it when I got it the other day, especially with the short tube. The combination of the fatter head and short tube was really neat, but I just had to put a 20700 tube on it and change the Mosfet and push push push. Am even entertaining putting an XHP-50.2 in it with 2 18350’s, but then I’d have to lose the driver and I’m really having fun with TK’s Anduril. See? Always wanting more, different, unique, and just never fully satisfied as a result. It’s taking a toll…

I probably learned to customize everything as a kid, my Dad always bought the cheapest stuff and it always broke, you had to figure out how to fix it just to do the job at hand. Now it’s kind of an obsession! Lol

An update to DBC-05….

I had initially designed this light with the 21700 cell to come out in mind, and now that I have a couple of iJoy 21700’s, figured I’d tweak the light to see if they really perform all that well. Smile

I pulled the XHP-50.2’s out, machined the head for a larger diameter and taller new triple reflector with better proportions in the individual reflector cups, put in new XHP-70.2 P2 3B 5000K emitters and got a surprise…. 32.2A at the tail! On the light box I got another surprise… the small Omten switch does not like 32 Amp loads! The plastic housing melted and stuck the switch in off position. lol

So I pulled a heavy duty Tofty switch from another light and rebuilt that lights tail switch assembly, installed the Tofty in DBC-05 where it’s really needed. And the surprises kept coming! A start lumens of 18,940.5 and at 30 seconds 16,318.5. Woohooo! Big Smile

My highest lumens to date and in a light I built from scratch, I’ll take it! Wink

Also cut some grip rings into the tube, helps aesthetically as well…

And a shot at the new reflector sitting over 70.2’s…

Ceiling bounce even in a big room is just insane! Even my Dad is hugely impressed, enough that he asked “You’re gonna mess around til you blow up one of those batteries, what then?” As I headed out to the shop to fit in the Tofty I sang “See you! See you on the other siiiide!” Wink

So, we’ve finally found the limit to those little Omtens. And Tofty has been out of business for a while, right? He was trying to sell his business many moons ago here, and I can’t remember if anyone actually took it up. I think you even made a comment that the Tofty switches weren’t really necessary, since the Omtens do so well…

EDIT: Oops, nope, it was Old Lumens that made the claim that tofty wasn’t necessary because the Omtens were good enough. Also, he wasn’t “selling his business” he was actually “giving away his project” to anyone who wanted to take up the mantle.

Well, the Omtens usually are good enough, but new tech and crazy builds are exceeding the limits apparently. The metal components inside a small Omten are very thin aluminum bits, they get so hot at high current the plastic box they’re in melts! The little spring inside was fine, but molten plastic flowed in around the switch components and locked it down. That was 30 seconds at 32.2Amps.

I almost stepped up to a large Omten, but figured the $25 Tofty was much more suited in this case. Thick gauge copper sheet makes the components and the switch can be disassembled for cleaning to maintaing a very good low resistance operation.

Amazing the Omten could hold it even that long! Shocked

I know, right? I tested amperage through the modes, got an initial output test, shined it around some then recharged the cells and did Turbo reading and left it on for a timed 30 seconds… when I shut it off the switch locked up in off position and wouldn’t return up, just simple locked in. I cut it apart to see exactly what happened and the black plastic was flowed in around it and between the plates, cementing it all together very effectively.

I’ve seen McClicky’s melt internal springs at under 10A, I’ve seen traces get blown on the switch board at under 15A, but I don’t recall ever seeing a switch melt down before unless there was a direct short in the circuit. I’ve got mini Omtens in lights pulling 18A and they’re working fine. I’ve got a large Omten on the tail PCB of my M6 that’s flowing 27A, so far so good. Just found the limits of the mini… lol

Thanks Dan, it’s an exhilarating experience. Big Smile

I’d been looking for 15,000 out of the 50.2’s, was a bit let down to “only” see 11,000+. Crazy how that works huh? So yeah, I was thinking the 70.2’s would surely do 15K, maybe 20K? Not at all disappointed with 18.9K.

Back to back, I’ve now done the most output and the most throw, with my DBC-06 making 815Kcd for 1.122 miles. Big Smile

Sure feels good after being out for so long…
