I doubt it. I’m not sure, but I think the KR1 driver’s regulated circuit only goes down to 5A as the lowest turbo level. This is fine for the W1/W2 LED options, and for XP-L and SST-20… but Nichia 219B can’t really handle that much power. It’s rated for 1.5A and really should be kept at 3A or less. So Hank would need to make a lower-powered driver for it, or use special firmware which never goes above 50% or maybe 60% power.
For some lights, that’s worth doing… But in a thrower, 219B doesn’t really make much sense.
Yeah. I don’t know much about it, but it sounds interesting. I sent him a quick test firmware just to help verify if the driver works, and to check if I’ve got the right pinouts… but I haven’t heard any more details yet. Just some initial hardware-enablement type stuff.
Meanwhile, I’ve been enjoying a KR1 W1 in 18350 form. It’s small enough to lose in my purse until I need it, and throws way farther than such a small light seems like it should be capable of. I leave it in lockout mode, with a manual memory level set somewhere practical, so I can just pull it out and use 2H for momentary at a useful brightness. The beam is similar to an Emisar D1S, but the light itself is only a fraction of the size.
There will be B35AR variant, but since B35AR does not work with DTP, it can only be mildly driven,
the brightness won’t be that impressive comparing to the multiple LEDs flashlight.
Nice to hear that, I’m still deciding how much current to use for B35AR. What is the brightness when you drive it at 2A? And which optic/reflector for B35AR?
