Thanks Del, nice to see graphs and charts… for me though the power supply ruins it. Kind of irrelevant information as we actually use cells in a flashlight. I understand the need for testing and getting solid evidence of what can be expected on that level though, so it’s nice to see the graphs on it. It would definitely be nice to have been able to test like that during development stage, at this end of it though, I’m not sure what is being accomplished. Not meaning to trash your work, it’s invaluable, just meaning to discover the perspective of how to use it from here.
And yes, the light is really pretty nice… it took me a bit to like the physical nature of it, but the beam profile has always appealed to me.
Which is why I’ve played with the modification of the few I have.
I might chase my own tail from time to time, but I also probably have the smallest 4900 lumen light out there. Certainly one of the smallest…. and with a 2 cell 18650 tube, it’ll be a 6000+ lumen Il Monstro!
For those new to the game, the Cree XHP-50 is a 6V 4 die emitter, essentially 4 XP-G2 dies on one substrate. I have 4 of those in a D80. Essentially 16 XP-G2 dies in the D80 head with an Ledil CUTE-4 Optic… had to slice the domes to get em under the optic but it works, pretty well actually. The driver is one of Wights FET designs, the A17DD-S08 I believe, with a Zener mod to enable the use of the 2 18350 cells. Efest Purple IMR18350’s allow 13A current draw for 4896 lumens out the front, I tested a pair of 35A’s at 19.1A for 6037 lumens. So now I will endeavor to cut a 2 cell tube for this light and see how it holds up. I’ve also asked GearBest to coerce LuckySun into a run of 2 cell tubes, in case anyone might be interested in any sort of 6V mods to these D80’s. I’ll be sure to start an interest thread if I can get any positive response from Lucky Sun on that. Awaiting an answer…
For those needing visual stimuli…
I built this last April using 2 Warm White XHP-50’s and 2 Cool White XHP-50’s. I somehow ended up with those 4 sitting here loose and decided to give tint mixing a go. The output is still a warm white, but not nearly as warm as had I used 4 of those little orange beastie’s!
I know I posted about this a while back, but we now have a lot more of these lights in some pretty talented peoples hands… looking forward to hearing what some of y’all do with em.
When I hear something from GearBest or LuckySun, y’all’ll be the first to know. (double contractions, don’t ya just love the South? [that’s you all will , in case you’re wondering])
