This is kind of exciting! 4 dies, packed very close together, might not exhibit the dark donut hole effect of it’s siblings, and factory domeless with high CRI? Wow!
Notice the dots are not lined up the same direction on the individual dies, but the line between the dies is very marginal…
Probably has something to do with the size of this thing. It’s XP size. Not to mention, the dies are crammed tight together. There probably just ain’t no room for the trickery it takes to get a dual voltage option.
I noticed the die lines running through it. I don’t think they will be visible when its running. I guess time will tell.
It should be simple enough to run one of these off a single Li-ion while still maintaining about 90% driver efficiency, in fact I think because of the nature of boost circuits it should be possible to maintain a higher average efficiency then AMC7135 drivers from 0.05A through to 2A (if Vf is not too high).
I would think it's going to take 4 cells, like in an SRK, but 4 in series, to get the voltage. Once this goes up over 1.5 amps, then you will be talking more like 13-14 volts, so I would think 4 cells and a buck driver would be better off than a boost driver. Buck is usually more efficient than boost and takes less amperage from the cells. Or at least 3 in series and a boost driver.
I could see SRK lights with four of these leds in parallel and four cells in series, or a Courui with a boost driver and 3 cells in series.
Yeah, but why would you want all that power going to a XHP-35, when you could easily power up at least a XHP-50 with that, and with high-drain cells, a XHP-70?
Sorry, the link messed up my quote block and I didn’t catch the error. Fixed it now. That was n10sivern that found those. I would love to have one with an XHP-35 in it. Run-time should be okay, as long as full-on Turbo mode was used sparingly. 0:)
Missing out on some ideas here. For the High Intensity version, that emitter is 2.4mm square. That’ll fit under 26.5mm TIR’s from Carclo, its input hole is 3.8mm. This next area I’m not sure about. But the input side from the Carclo 10511 family is 1.7mm so not certain what will happen to light from the outer area not under the hole. What I’m thinking as a good light build is a two cell light with a driver to bump up the voltage and yet fit into the P60 or C8 family of lights.
I have one with a Ledil Mirella and a single XHP-70 that does some 5500 lumens. The extension tube went to a Solarforce M7, took a little modification but it all works well together.
So yeah, what I was thinking, an extension tube would allow for what, 4 18350’s? Maybe 3 18500’s? (Although I have yet to find an 18500 that will put out like the shorter 18350 Purple) Then it’s just a matter of determining the driver, right? I’ve tried 12V triple XHP-70’s on 3 18650’s and they can’t do the forward voltage. But 4 parallel XHP-35’s with 4 18350’s, run through a Zener modified FET driver, that could be interesting…. the problem as I see it is that 1A max current thing, wonder what they can REALLY take?
Would this maybe do 8000 lumens? Don’t know, but if I can remember all this I’ll probably give it a go.
Edit: Have some of the HI XHP-35 on the way, y’all don’t let me forget why I ordered these ok?
Edit II: Ok, so these fit the XP footprint which means a triple would be easy to do in the X6 with a Noctigon 32mm mcpcb. I have copper heat sinks for this, and the Ledil Cute-3 optics, so all I need is for the emitters to come in and we’ll see what these puppies can do! (backorder on the XHP35 HI til Aug 5, they’ll probably ship a day or two quicker, we’ll see.)
Edit III: Looks like, from some extrapolation of the data sheets, we should expect something in the 4400 lumen area with a Vf around 12.6. Not stupendously outstanding but not at all shabby either.
