YES, YOU ARE RIGHT!
Looks nice. This company sure knows how do marketing. I bet 9 out of 10 people would buy this light over the Zebralight SC52 just by look alone. Who here ordered the pink one already? I won't be one of them though. The mode spacings won't work for me. I need the first two modes to be around 1/30lm.

Hi Klarus
There are a few questions posted in this thread. If you have time could you please take a look at them? Thanks!

I guess those high lumen declarations in small form factor lights is not the best way to go. Just two examples: S1 Ti @ 480lm -- in a minute its heating curve is so steep that I switch it off manually being afraid to fry internals. Archer 1A v3 @ 200lm -- I barely feel its warming and can use to full extent.
Battery junction is where I've seen them.

I thought sub-lumen meant less than one lumen? I've seen that word on CPF when discussing moonlight/firefly levels. Am I using the wrong word? :thinking:

I looked this up at one point, and posted the info in a discussion elsewhere ....
For reference, full moonlight on a clear night might be about < 1 lux. Simplifying the math and conversion of units, I'd consider flashlight output of 1-3 lumens to be "moonlight" . A candle would also make about 1 lumen.
A firefly supposedly produces about 0.025 lumen, and flashlight outputs < 0.1 lumen are usually considered to be "firefly" modes.
Interestingly, moonless starlight with "airglow" is listed at 0.002 lux in Wikipedia.
I definitely agree that there is (and should be) a significant visual difference between "firefly" modes, and "moonlight" modes, as well as probably (to some degree at least) plain "low" output mode(s)
And yes, the term "sublumen" is indeed useful and appropriate for output of < 1 lumen.

Ouch, another almost perfect 1xAA. But as usual, something kills it like the 5>90 spacing. 1lm>50lm>300 would have been great. I like a sublumen, but can live with 1lm if pressed for 3 simple modes.

Yes, although I would prefer the medium more towards low ... such as 1 / 20 / 300 , or even 1 / 15 / 300
I've had a few of them and the quality is great. Never had any issue at all.

No one will because they do not make pink. The colors are black, red, and blue.

My previous question about this flashlight accepting protected batteries has been answered.
I just saw a recent post by Klarus titled "For MI7, 14500 li-ion battery, Klarus have". The battery is a protected button top.
So the flashlight itself has a lockout feature and over-discharge protection and it also accepts a protected 14500 battery. Awesome! :thumbsup:
I see this battery for sale on a site that offers the Mi7 (Mi7 is pre-sale and sold separately) but the store doesn't offer free shipping (expensive outside of USA).
Hopefully the other site that does offer free shipping for this light will soon have the battery in stock.
Expected shipping date for the Mi7 is July 9th (6 days from now).

You are really professional! Thanks, we learn a lot!
May I know why you choice this lumens and what situations will be used of that 1/20/300 or 1/15/300 lumens?

Ooh, that's a good point I had never considered.Interesting! I didn't know that. I thought "moonlight" and "firefly" were simply different ways to describe "very low lumen" output.
So "moonlight" is 1-8 lumens and "firefly" is sublumen level. Now it makes more sense!
Thanks for the information. It was very helpful!
