I’m trying to find drivers that don’t use PWM. It looks like linear drivers do this. They somehow are able to output a stable reduced voltage current level to control the brightness of the LED. I’m not very familiar with this driver design but it makes sense and that there would be no flicker. Usually LEDs have a limited voltage range and if the voltage goes too low the LED simply turns off. So it’s really tricky getting moonlight and low levels.

Edit- This design seems to limit the current through the use of a linear regulator (adjustable current limitor). I’m still trying to understand it.

Just saw your comment about looking for non-PWM drivers. I’m not that familiar with drivers, but I generally test if each flashlight has PWM (my method is a bit crude — I shine the light through a small portable fan blades). I’m not sure how fast the fan blades spin, but for BLF A6 driver or Biscotti or Bistro or NarsilM or Anduril, I can still “see” the fast PWM pattern on lower brightness levels, using this method.

However on some flashlights I tested, I couldn’t “see” PWM, so I determine they have No PWM (or are faster than what I can observe by shining flashlight thru the spinning fan blade).

These are some flashlights I tested using my crude method above, and I can’t “see” PWM on all their brightness levels (lowest, medium to high levels):

AAA flashlights:
BLF/Astrolux A01 (Nichia 219B) (Manker driver)
Lumintop EDC01 (XP-G3)
Lumintop Tool AAA (XP-G2)
ZanFlare F3 (XP-G2)
NiteCore TIP CRI 2017 (Nichia 219C) (keychain light)

AA/14500:
BlitzWolf BW-ET1 (XPL-HD)

18650:
Eagle Eye X2R (XM-L2)
ZanFlare F1 (XPL-HD)
Convoy S2+ (SST40 “4-mode” driver)
Wuben LT35 (XP-L2)
Eagle Eye X6 (XPL-Hi)
Sofirn SP32A v2.0 (XP-L2)

21700:
Sofirn C8G (XHP35-Hi)
Sofirn SD05 (XHP50.2)

26650:
Sofirn SP33 (XHP50.2)

(I think there may are some more I failed to list above)

I have Acebeam t27,h30 and h40. They are non-PWM

[vik267777]

Any chance copper head will be produced?

[JasonWW]

I’m not looking for non-PWM drivers to study anymore. That’s old. Thanks anyway.

[morelightnow]

Are there any greens left?

Also, does anyone know what the input voltage range is?

[JasonWW]

@morelightnow

I’m not sure what you mean, but the driver runs on “6 volts”. So like 5.6v-8.4v.

You can still can order. [quote=morelightnow] Are there any greens left? [/quote]

[morelightnow]

Ok, thanks Jason. I was asking because I like to use LifePo4 batteries in my lights. I may just get some 30Q’s instead.

I got my MF01S today, awesome light. Anyone have tips for attaching the lanyard that came with it? Doesn’t seem that it should be that hard but I can’t get the ends to fit through the holes going from the inside out. I can get them through going from the outside in, but doing it that way would prevent it from tailstanding…
Also, this light is supposed to be red, and it is pink. Disappointed in the color.

[brenden23]

Interested in code for blue MF01F and diffuser!

Do you have a spare split ring lying around in your house?

Ordered mine , thank you. Any drawbacks anyone can think of using molicel 26a’s in this? Had good performance out of the couple I have. Figure I might run with more for this and the blf lantern.

[man_of_light]

Interested.

I would suggest you something like this: https://www.aliexpress.com/af/camera-screw-d%25252dring-release.html?SearchText=camera+screw+d%252dring+release
But please take one with the a screw which is as short as possible, because in the tripod screw hole is not much room.

I had several, but I guess they were all too big, because all I achieved was scratching the light trying to get them on. I ended up taking apart the strap that came with it, and cutting the ends at an angle before burning. EDIT: I was going to post a pic from imgur but can’t get it to work. Try this link

I am interested in a Blue MF01S 4000k or 5000k. The blue seems to be completely out of stock. Will more be added?

From August 2, 2019

Once they are gone, they are not making more.
