What eventuated out of this?
An ideal LED for a C8 and single 18650?
Or more a realistic option for a TM16 with quad XHP35?
Perhaps the TM16 is more suited to XHP50-70?
I know of one light which can possibly benefit from this LED. The XHP35 can do some amazing things, just in rather unconventional situations. The hi-CRI at 5000-6000K is one thing that we often never have access to, but I’ve seen another side to this LED which I am quite interested in.
How many lights currently use a boost that we know of out there?
The TR-S700 is one that does use a boost circuit. It has an amazing hotspot for 7-LEDs. It is also beneficial as the cell count, whether using 1, 2, or 3, doesn’t really effect initial output in the S700. It is just about ready all of the time to get up and go.
SC600 Mk III - now available with XHP35 in both cool and neutral tints.
SC600W Mk3
SC63 - available for preorder in both cool and neutral tints. Supposed to ship at the end of the month. SC 63w
If Zebralight can get a sufficient supply of emitters they are also thinking of offering the above lights in 90 CRI XHP35. That would be pretty nice: A tiny SC63-sized light with 1100 lumen output of hi-CRI 5000K light.
The high-CRI Zebralights sound nice, but I worry about whether they’ve finally fixed their tinted lenses and if the emitters still make a Cree rainbow. It could turn out to be a much lower CRI than advertised, depending on details like that.
Now, if they used a dome-less emitter, that would help a lot. And an untinted lens.
Even more amazing is that they accomplished this with a comparatively small boost driver that scales up to 12V or more from a 4.2V cell. I hope they can maintain CC boost regulation down to the claimed 2.7V LVC. Very cool indeed!
You’ll probably have to use 4 18350’s in series to get the voltage to run the emitter. I don’t know of any boost driver to up the voltage of two 26650’s to meet the 12v requirement.
The LD-51 does that trick. Driver for XHP35 LD-51
I’m currently talking with gearbest about that driver.
It’s not a direct replacement, it’s 28mm instead of 20.
Any ideas about modes? How many and what percentage?
Good question? Did you look at KD photos showing different power modes… none of them make much sense, especially the last one showing 1.6A @ 14V clearly being displayed on a bench power supply.
