XHP-35

Click on the data sheet PDF link

Scroll to bottom pages 36 & 37 have pictures if you look close you’ll see it.

Aha! You’re right! I had never scrolled down the Datasheet yet. The pictures at the top of the Datasheet don’t show any lines at all, no matter how closely you look at them. Interesting that on the XHP35, there is phosphor coating all the die area. The XHP50 and XHP70, I think, have gaps in the phosphor between the individual dies.

I can imagine a 2XAA light, modded to use one of these, with 4X14250 cells powering it in Direct Drive! Or, a 4XAAA light, using 10440’s. Anything larger would be capable of driving a XHP50 or XHP70, so it wouldn’t make sense to have one of these in a larger light.

Another possibility is using set ups that use 4-18650’s to run say 3 XM-L’s in series to now run 3 XHP-35’s in parallel. Now we’d get less current through switches, springs and wires but have better wattage. Tiny Monsters from Nitecore and G, S, M series from Eagletac.

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…

Taken from the datasheet and enlarged 50%. :wink:

But no 6v option? Major bummer

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.

Small 2S 18650 with 4x 18350’s or 16340’s in series. Something like a Convoy S2 with an extension tube.

Or 4x 10440 like this or this or this

I know, it’s doable. But I’m not comfortable with that many cells in series. That also puts you at almost 17v fully charged.

I bet the LED could handle the 17V as it is 4 die array.

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’m thinking something like this:

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?

That second one looks perfect!

4x 10180 in a 2x AAA tube light (mini maglite for example)

That would be cool! Runtime would suck in a big way, but still….

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.

An EE X6 w/extension tube and 35mm Ledil Cute-4 optics. :wink: Quad XHP-35, that should garner some attention!

Okay, so how much ya sellin’ those for, Dale? :wink:

Dale did you make your extension tube yourself? I think I would like the X6 proportions much better if the tube was longer
