H17F - programmable driver with full thermal regulation

Is there any plans to develop the same driver without the FET/DD option?
The PID is the main feature that makes it stand out from most drivers but this is not available in a standard linear driver.

Ultimately, would this driver be safe to use on a single Nichia 219C R9050 in a 1 x 18650 build. I am reading that the Nichia 219C should not be run on DD as it can easily overheat.

Thanks

Grrrr, I just got up from my night shift nap. This one i actually knew.

We use to goof around with it in the old IRC cjat rooms using different open source chat clients.

Oh well... early bird gets the worm.

Congrats.

When can I purchase?

5LMAO see how asleep I still am. This was long done. Lol

I wouldn't use it on a single 219C with a good high drain battery battery, even though it doesn't have as low of resistance as a normal FET driver so you can get away with a bit more. Since the modes are fully programmable, you can turn down the highest mode to whatever you want, or disable the FET entirely (I would still keep it on, but just turn it down one mode level from the top).

Any plans for maybe a 20mm?

That's completely up to DrJones. I wouldn't mind seeing a few different diameter options.

Yeah me too.

How well would this driver work with an XHP50/70 or would it work at all?

Was this question answered? I normaly prefer a L-M-H setup and want to access the higher modes quickly bydouble or triple tapping from off.

How do you programm the double-tap mode? Can you disable it? I do not find any information in the description…

When programming the brightness it cycles through the modes, right? So you can accidently go into direct drive, I think. What happens to the LED if the battery allows very high amperages?

Thanks for your help!

It’s a medium fast double tap. Yes. You can go into by accident when changing modes fast.

When programming it ramps up from minimum so you can avoid direct drive. The problem is that I think double tap and maybe the last mode are at max. I wish Dr Jones would limit the stock max modes. I was programming with a single 219B and (silly me) a high current cell. Nothing blew up but the LED would go blue after a few seconds.

Thanks, Gunga!
So I have to reconsider, whether the H17F is right for me. Would be great, if you could disable the double-tap mode in the config menu.

After programming it’s fine (no LED blue) but double tap mode can be a bit annoying. You get used to it though.

I love the double tap Turbo feature, Normal people can use the light and never enter or know (Turbo) is there :wink: , it is only the Professional Flashlight experts that get annoyed when fast clicking! :smiley: Or forget to get out of Turbo when shutting it off, next turn on BAM! :person_facepalming:

Double tap can not be disabled, but you can set it to any brightness level you want. And yes, it is fairly easy to accidentally access it.

I use the double tap to always go to moonlight mode. I try to have ML on every light that I build and it is nice not to have to go past a mode that makes so little light you cannot tell it is on, but at night I can double tap a know that it will not blind me the next time I turn it on!

I would like to echo the hope for the H17f in other sizes as well. I would love to see it in 20mm.

I LOVE the double-tap feature on this driver.

It’s what makes this my absolute favorite clicky switch driver. The shortcut to turbo works really well.

It would be my favorite if it could reverse modes. But, given all that is programmable on it… I bet there is not room in the firmware for the mode reversing bits. I do find myself using the triple down style often for this feature. But having the ability to set every brightness level is awesome.

Are you talking about acending vs descending order? H/M/L instead of L/M/H?
If that is what you are talking about you can do that with this driver.

No, I am talking long press to go down to the next mode.

Ah I see what you’re saying. Yeah that would be a nice feature to have for these drivers.
