I haven’t seen anyone report on this LED, but I assume it is the flip chip version of the xhp35. I think there will be reduced interest in this version because it keeps the 12V which makes it hard to use, but changes to flip chip which makes it not as good for throwers. It (with 6.25mm^2 die area, measured for the first gen) fills the (not very necessary) niche between the XPL2 (4mm^2) and XHP50.2 (8mm^2). One positive is that since there are no bond wires it can be over-driven more than the first gen xhp35.
The upper limit for the first-gen XHP35 is surely due to the dies themselves?
Maybe bond wires contribute some…
Wonder how this would be to dedome? Or if Cree will release a HI version?
Like EasyB says, XPL or XHP50 are both more attractive options for most cases.
yh I don’t see the point of this. Hopefully Luminus come out with an SBT40 or something.
It’s announced since 2018
Yeah XHP35.2 HD has been available for a while, just haven’t seen it in any production flashlights.
I’m more interested in the driver in this light. Looks like it might be a single cell 20mm 12v 2A boost?
only 1700 lumens ?
1700lm from an XHP35 is about 15W (1.1A), which isn’t pushing it that hard.
15W boost from single cell, probably the common TPS61088 driver.
News update: XHP35 V1 is being discontinued, also V2 HI confirmed:

Has anyone found an in-stock supply of XHP35.2 HI in flux bins greater than D4? I hope to find E2 flux bins or greater in 5000-6500K to reflow into my stock GT. Crees data sheets appear to be dated and they are notorious for not listing all available variations. I’ll probably settle for a D4 if nothing turns up. Mouser has plenty in stock and they are easy to deal with.
Still no listings showing for XHP70D-H0 variations (XHP70.3 HI). Id love to try one in a GT with a TA driver, assuming high flux bins once available. Cree’s data sheet looks promising.
I’ll probably cross post this in a few other threads to see if anything turns up…
