I love watching it stand up against a $400 light. 
These are orsm dedomed. Mine was lighting up a non reflective surface at over 600 meters according to Google earth. 4 of these would be amazing at 5 amps each.
thats what impresses me too, a $29 light with a few easy mods that can out-muscle lights in the Throwing class that costs 10 times as much.
Will be soon if all goes well, as its under construction now like below 
This one has a little more “out the front” Throw! I think the shocker would go well mounted on this!!! Better than the $7K SF HellCat/fire thingy.
EDIT: I was just going to post a pic, but I figured some of the Non US folks may not know what this thing really is. But this link sums it up. Even if guns aren’t your thing, this is amazing anti material device!!
Nice comparative beam shots. You have that baby singing. Looking forward to your monster eventually coming to life.
That gun is so awesome Ricflair. I want one.
one of my favourite guns. 8) built by a distant relative. :bigsmile:
Scale wise it may look a little more practical with a truck battery? 
It will likely need a ton of Amps to drive it, and hope 8 - 20R 18650’s can deliver.
What ever became of this project?
Its still going to be completed some day, though its been on hold for a long time. Its partly built and in a box, but placed it on hold once i heard about the XP-L HI coming out. I will continue work on it maybe over the winter.
C’mon, it’s been another 3 months already.
lol* i know. As soon as i can get some time i will work on this. its partially assembled, but got some more work work to do before i can fire it up for testing.
Thats an interesting project DBSAR, but what about heat sinking? Will you be mounting the back plate to aluminum pillars to make it part of the heat sink, or using only the existing heads to exchange all the heat? My 2 x 26650 DST mod overheats the host very quickly @5A, which makes it more of a 1-2 minute “wow light”.
Ive considered a 4-6 XHP35 HI/DST mod with remote cell pack, using long aluminum or copper pillars inside the hollow pills to connect the heads to the mounting plate via a press fit. Then adding a fan cooled CPU heat sink on the other side of the mounting plate to exchange the heat. I hate to make alterations to so many brand new DST’s that would not be reversible, so Im stalled at the head scratching stage. Any ideas?
I have some ideas on increasing the heat dissipation, (one being that back plate may be substituted with a 1/2” thick copper plate, then copper 5/8” rods extending through the DST’s large aluminum pills directly contacting the Noctigons and contacting the plate. Also adding a fan in the middle to help with cooling. Another idea is heat pipes to each DST pill. I even though of extreme cooling as in Computer CPU Liquid cooling, but that will add a lot more bulk & mass to the project light. As this build may end up using dedomed XP-G2s, the heat output will not be so great as using XM-L or XP-L emitters. Dedomed XP-G2’s on copper seem to be the best emitter so far to achieve the highest KCDs at 1-M. (as proven by the Deft-X.)
Those are all some great ideas. Then you wouldnt have to modify or sacrifice any of the stock host parts beyond the pills (which could be changed and reused with the hosts later… if you wanted). I have a large CPU cooler with 4 long heat pipes that might be able to be modified to fit inside copper rods pressed into the pills of 4 DST heads. It easily cools a 100W Bridgelux at max continuous power, so should do well for 4 x XHP35 @ 140W total. Ive also seen copper heat pipes sold separately. Your idea of dedomed XP-G2’s has me rethinking my build. While the XHP’s would wow a light meter, the jump between the two as viewed through human eyes wouldnt be quite as impressive. Then there are the power and cooling requirements of 75W for XP-G2 vs 140W for XHP35. Whichever route taken, I especially like the idea of being able to easily dial-in the optimum focus for each light head by twisting the threads. Optimizing the focus has always been the most frustrating part of concocting a dedomed thrower build for me.
Good stuff… and do-able! :bigsmile:
So far the dedomed XP-G2 beats everything else in sheer intensity in my tests. That photo above of the modded DST out throwing the mighty SR90 & BTU Super Shocker was done with a dedomed XM-L2, the XP-G2 produces a tighter even more intense hotspot when “dialed in” and focused. The reflector in a DST in my mind is the best ever designed to be able to focus a throw beam with an LED in a traditional reflector-based light. I wish the DST did not go out of production. Fortunately i managed to snag 7 of them when they went on clearance.
Surface brightness determines throw. I think it was Kenjii who used a large Trustfire SST90 host to create a +700kcd thrower using a dedomed XP-G2, so Im definitely a believer. I think the reflectors are sold separately at DX, but then you’d have to come up with a means of securing them in a custom head… which would mean much more work, and it wouldnt look as nice as the beautifully anodized DST parts. I agree, the DST was an amazing creation. I always laugh when considering other thrower hosts that come and go. They just cant compete. I was only able to snag one DST at HD but picked up 5 more on ebay.
I have over 50 x Defiant 3D 650’s… also an amazing powerhouse and host.
You have 50 of them? wow nearly a crate full.
Outstanding pics! That Shocker I measured at bout 500 kcd w/unprotected topped off 25R's but only at 5 meters. Output drops pretty crazy along with the cells, so maybe you are getting 350-450 kcd here, depending... Funny because it looks like it has no hot spot whatsoever compared to the DST. I still have 3 DST's, 2 unopened
