DBC-05 Triple XHP-50.2 Scratch Build !NOW XHP-70.2!

Thanks, it’s “growing” on me. :slight_smile: hahaha

It feels absolutely GREAT to see you building again and back in the game. I missed you and your talent!!! :star: TL

How much bigger is your 05 compared to an L6?.

The 05 has a 65mm triple reflector that’s 32mm deep, so overall it’s quite similar in size but much heavier due to the massive copper pill section.

I paid $40 for the largest diameter Te/Cu bar stock I could find, it was 3 lbs and a little when I started. The head, no bezel no reflector or emitters, just the bare head is 1.6 lbs now.

Also just completed DBC-06.7, a thrower that I didn’t draw up plans for just made on the fly at the lathe.

It’s really exciting to come back in after all the healing process and not only make a personal best thrower but rebuild this 05 for a personal best output, 2 in one week. Yeah, ecstatic about that! :smiley:

All of this is sooooo cool! :) Great thread and projects, really fascinating stuff! :)

WOW! Very impressive!!

For the record…

DBC-05 is a triple XHP-70.2 now, pulling 32.2A at the tail and making 18,940.5 lumens in Turbo at start up, 16,318.5 lumens at 30 seconds… this on a pair of iJoy 21700 3750mAh cells. Current draw is so high here I was forced to dig a premium Tofty switch out of an older build. :wink: I’m sure a lot of newer members don’t know what a Tofty switch is, we had a member here that was in Great Britain that had switches made to order using heavy copper sheet material for the electrical components and designed it in such a way that it could be disassembled and cleaned, rated at 15A it is capable of so much more. These were around $25 a switch if I remember correctly.

DBC-06.7 is a large thrower sporting a 97.5mm reflector and using a single 32650 cell. It has a de-domed XM-L2 in it that was de-domed by MaxToch for their Shooter series lights. With a throw of 815Kcd for 1.122 miles it’s pulling only 4.61A at the tail. The new gen XM-L2 keeps amperage lower while still doing a respectable job in the lumens department, making 1652.55 lumens in Turbo level (7 levels with reversing at the tail clicky)

Nice clean work Dale!! You can come & work in my shop an day! Clean design! TL

Thank you Dan, really appreciate that coming from a true lathemaster. :wink:

Like your work great job. How about telling us more about this new cool looking thrower.

This design makes me wonder… has anyone made a light where the reflector is a structural part of the body? Like, the reflector screws into the pill, its outside is exposed, and then the bezel threads directly onto the reflector? No outer shell between the pill and bezel, just the reflector holding the two together.

That’s how this one is made. The reflector had a nice thick belt around the lower third section, I threaded it and it goes into the adapter, which in turn threads onto the battery tube/head which is all one piece. Then I cut threads on the belt around the top section and made a bezel to screw down onto the reflector itself. That second inch or so is the reflector.

The emitter/MCPCB sits on a 35mm x 35mm threaded copper core that is flush with the top end of the tube/head, so the adapter allows for easy focus of the emitter to make it easy to try different emitters of varying types. The mid section that resembles a Courui D01 head, that’s the adapter section.

After that picture was taken I cut a bevel on the bezel that intersects the belt on the reflector and makes for better lines.

I’m not sure if your after a commercially built light or otherwise TK. As well as Dales this years OL comp light I’m building which you have commented on and last years OL comp light are both like what you describe.

Ah, that makes sense. I thought it looked like the reflector was exposed but I wasn’t quite sure.

The contest entry was something I was also wondering about, because I wasn’t sure which parts were finished and which parts still had more steps planned.

In any case, you both thought of it before I did, and it looks like it works well. :slight_smile:

I guess there are no technical difficulties to anodize the outer side of a reflector w/out harming the inner one?

There would be issues if anodizing, yes. Many of us that build a light with a lathe do not anodize at all. Built my first one 2 years ago and polished it, still the same today.

Update on DBC-05… I jumped on the early bird special and got 2 of the new Samsung 30T 21700 cells that HKJ tested as awesome. And Awesome they are! I now see 48.8A at start and 21,631 lumens out the front! At 30 seconds it’s down to 41.9A and 15,800 lumens. I stopped at 30 seconds because the wires (12ga Turnigy with gold plated banana plugs) were too hot to hold! And the big TeCu head, also blistering hot in a mere 30 seconds! Yowza!

This blows my mind, the amp draw is just ridiculously high but even though the 30T is only a 3000mAh cell the drop isn’t nearly as quick or as steep as I thought it’d be. Video here shows it on the lightbox, as filmed by Daniel. :wink: For those that want to watch the lumens my lightbox has a 0.345 multiplier to get actual lumens. The meter is in x100 mode so what you see on the meter gets two more zero’s on the end. :wink:

Before you get too excited about these cells, they were $18 each at IMRBatteries.com and no USPS shipping, I chose the cheapest which was FedEx and it was almost $12 extra making it way too close to $50 for 2 cells! Yeah, I’m insane. But 21,631 lumens in a light I built from scratch! :smiley: Crazy stuff, Maynard!
