Curious about the DM1.12 lumens/cd figure for the SBT90.2 throw LED as well for SST-20 flood LEDs - back-of-the-napkin figures are fine.
Has Hank announced any plans to make a 5050 MCPCB for D4SV2?
XM-L footprint (5050) LED’s are huge. I doubt there would be enough space to use them as aux LED’s.
The new drivers being worked on are for KR1/KR4. He hasn’t announced any new drivers for other lights yet.
Looks like xhp50.3 hi is that long-awaited step up in performance among flashlight leds… That’s why I’m asking. Project like d4s with 4x xhp would be a real rocket. If it can even be run on a single 26650. 
Any idea when other D4Sv2 colors besides cyan will be back in stock?
It’s about 128kcd, 4500lm for the SBT90.2 LED on turbo mode.
Beamshots!!!!
Looks awesome! What driver is that using? I assume it’s a boost driver? How many amps will that draw from the battery, and what max lumens and candela can we expect?
Hank, so happy to see a GT-FC40 KR1 ! is this running the same driver that the xhp35 HI will use? I didn't think that was possible due to Vf differences.
A GT FC-40 K1 would be amazing too!
Now we need FC40 in DM11 and B35 in KR1…
Can’t be anything else since the the LED is rated 12-14V and input is a single cell.
Hi Hank, this is a wonderful development. Will it be possible to get GT-FC40 in a KR4 as a mule?
What’s the throw on this?! Could you do a beamshot next to another kr1, or a regular kr4, or a dm11 with b35am? Thanks!
Wow, that was unexpected. Any plans for other high-voltage emitters in the KR1?
He’s confirmed that B35AM and XHP35-HI are coming soon as well.
Is there any more voltage emitter than FC40?
No reason to think 5050 LEDs fit under the optics…
Got the D4SV2 B35AM 2700K today . It’s the most rosy 2700K that i own ( sst-20, 219b, e21a, lh351d, xpl-hi 8A and 8D ) .
XHP 35 HI stock quantity is quite low, it will be put as on option on the site, if you need it, please send us an email for the customs build.
