Somebidy on reddit said that Hank told him that boost drivers are taller for 1mm and in current D1 design it is not possible suggesting only 3V options can be done.
A 21700 battery and tube with threads will not fit within the existing space allowed in D4V2’s, DW4’s, DT8’s, and D1’s head. To fir a 21700 battery, the heads would need to be redesigned or the tube would need to be extended necked down at the head end and have a PCB & spring added to take up the extra space, similar to K1’s body tube. I would be happy with either solution but due to their complexity, I doubt either will happen.
absolutely! I have updated all of my D1 and D1s with the 7.5amp Linear drivers and they're great. No FET needed, they push osrams, sft40 and xpl-hi really nicely!
Man, I had such a hard time letting my D1 go last year. I’d love to see an updated version. I’ve been asking for a D4 sized single emitter light for years.
D1 if offered with a boost driver, 519A 4000-4500k in green is on my list. Hopefully Hank brings back the original Emisar green.
On another note, I have a boost driver D4 with a lighted switch. I noticed that when ramping the switch brightness goes from low to high. In Anduril that used to correspond to cutover points from regulation to FET, but what does it mean on a boost driver?
Ah, rats, maybe I was thinking of a buck/boost like what Skilhunt or Zebralight does? Or are they just CC like Hanks newer non 7135 based drivers? I sort of lost track of driver understanding when the newer regulated drivers came out.
The current 3V drivers are linear+FET , but with discrete component instead of 7135 chips, higher regulated current and no PWM, and boost : 2A12V for most configurations and 3.6A6V for B35AM.
Zebralight used to have buck-boost drivers but now they use buck for 3V LEDs.
