Ideally more like 8 and 40 though, instead of 3 and 100.

Edit:

The actual lumen numbers really depend on the beam pattern… which, for a C01, is generally pretty floody since it’s a bare 5mm LED sticking out the front. So I’d suggest higher lumen numbers for this than I would for a throwy light.

OTOH, since it’s 1xAAA, big numbers won’t last long. I basically never use my BLF-348 because the battery life is way too short and it has no lower modes.

So, at a rough estimate, I’m thinking something around 5 to 10 lumens would be about right for most of my purposes. Maybe even slightly higher, depending on how floody it is. But I don’t really have much use for 3 or 100, since it’s too low and too high.

I’ll buy one or two (1 or 2) as is….. HL.

BUT…. LH is GREATLY PREFERRED. Thumbs Up (always start in Low NO memory mode)
With the LH config I’ll get several. (more than 2)

Make it 3 mode, 8 & 40 (as TK suggested) … then around 120 or so.
Just a wish / opinion…. Wink

If it was up to me (it isn’t), the modes would be HL but lower values:
20 lm High first, and 0.20 lm Low second

I wouldn’t buy either light. 3lm is useless to me, and I have no use for what would effectively be a single-mode 100lm light either.

It’s unfortunate, because I was looking forward to this light, but I need an LMH sequence along the lines of 15, 40, 100lm. I’d be fine with moonlight, 3, 15, 40, 100lm too, though – I don’t mind skipping to the mode I want.

Thanks for clearing that up for me. Wink

Last mode memory would be essential.

If 3 modes, then: 2.5 lm, 20 lm, 100 lm
If 4 modes, then: 0.8 lm, 6 lm, 35 lm, 100 lm

i have never seen what i want: even log-spaced levels

.3 1 3 10 30 100 300 1000 lumens
with a FAST way to switch them [like half taps go up]
and a way to go back {longer tap}
and no memory
and after 1000 lumens it starts back at .3

the BLF A6 ALMOST does it this way

Very low then high for me. It needs to have firefly mode, I can live with a lower high mode for a longer battery life

Something like: 0.05, 8, 24, 72

This is a 1xAAA twisty. It won’t get very bright, and it’s not very easy to “tap” for variable amounts of time like a reverse-clicky button, so it’s probably best to stick to only short and long intervals instead of short/med/long.

About log-spaced levels, that’s one of the options in the ramp calculator, but it’s not the default or recommended setting. Most research suggests a cube-root model instead of log. Here are a few “evenly spaced” ramps, using different curve types:

  • 0.30 / 24.9 / 88.9 / 192 / 335 / 517 / 739 / 1000 lm: Square
  • 0.30 / 8.03 / 37.1 / 102 / 216 / 394 / 651 / 1000 lm: Cube
  • 0.30 / 2.96 / 14.1 / 46.5 / 122 / 272 / 544 / 1000 lm: Fifth
  • 0.30 / 1.66 / 6.95 / 23.9 / 71.1 / 187 / 450 / 1000 lm: Ninth
  • 0.30 / 0.96 / 3.05 / 9.70 / 30.9 / 98.5 / 314 / 1000 lm: Log

IIRC, the blf-a6 used a cube-shaped ramp. On some newer lights with higher output, I’ve used a fifth or even a ninth, in order to put the lower modes closer together at the expense of high-end resolution. I don’t think I’ve ever actually used log in a production light though, because it tends to cluster the low end together a little too much.

“Ideally more like 8 and 40 though, instead of 3 and 100.”

+1 what TK said.

It’s a small back-up light. The 8 would hopefully be like the C01, with a bump to 40 as reserve without draining the battery.

(I completely missed the “PRO” development.)

Seeking the light.

The “pro” was already planned before the C01. When I asked Barry/Sofirn if they would make our Yuji 5mm twisty, they were directly interested because a small AAA twisty was already planned by Sofirn, just not one with a low output 5mm led. Still it was pretty awesome that they went for it Smile . So the C01S is the type that they originally wanted to make. I did advice on how they could set it apart from other AAA twisties (especially the cheap and very high quality Olight i3s and i3e), so that is why it has modes and a high CRI SST-20 led. And the Noir-tail of course Cool

I am in for LH. Buy Low sell high Ughh

I think I agree with the fellows, I would prefer 5-10 Low and 50-60 for High. Just my 2 cents.

I was not involved in which modes Sofirn has chosen but the stock 3lm-100lm is perfect for me.

H-L is only usable for keychain light for me.
For EDC-light I prefer L-(M)-H with a sublumen mode.

My guess is, the nghts in urban China are never dark enough to appreciate why some of us want low modes.

Shedding light on China’s dark-sky problem
By Zheng Jinran | China Daily | Updated: 2016-10-25

A recent survey suggests that for many people, a glimpse of the Milky Way or other parts of the visible galaxy is no longer possible as a result of the affects of artificial lighting.

The New Global Atlas of Light Pollution, published in the journal Science Advance, shows that 60 percent of people in Europe and almost 80 percent of North American residents are unable to see the Milky Way. More pertinently for China, it also shows that light pollution makes the nebula invisible to people who live in the areas around Beijing and Hong Kong.
