Dear Klarus Fans,

Let's see how Klarus cool of klarus MI7, A colorful 1 AA flashlight with MAX 700 LUMENS.

It is probably the turbo output using a 14500 lithium ion cell. Not an AA.

The site says 330 lumen for 55 minutes on AA. Nice!

Klarus, a few questions please :)

How long can it maintain 330 lumens/700 lumens before stepping down or dimming? I assume a few minutes?
Does it accept protected 14500 batteries?
I don't see it for sale yet, can you please tell us when this will be for sale? :)

ledsupermall has them in stock 39.99 never ordered from them ? Gonna wait for others to get it in stock & possibly a better price, ready to buy a blue one.

I see a different store selling this on sale for $39.99 (regular $44.97). They don't have them in stock yet. I'm not sure if I'm allowed to mention the site selling it.

I really like the instant access to moonlight or high outputs so that I can avoid the strobe/SOS features (assuming they aren't hidden).

I've been looking at so many different AA lights recently and the Mi7 has so many great features that I'm tempted to buy one right away, rather than waiting to see a review. From what I've read so far, it sounds perfect. :D

I'd definitely buy one right away if there were a group buy. :whistle:

+1 for this answer. Also wold be interested to discover whether it has a "nub" on the POS contact or a flat disk...because I have a handful of 14500 cells without a button top and they won't work in three of my lights.

This light looks like something new! 700 lumens from a 14500 is great if that's accurate. 300+ from a AA is not bad either. [emoji106]

Very interested! :D

I think the ZL SC5 is still the brightest and darn near dimmest 1xAA on the market still even so something the size of a 1xAA light doing 70O lumens lithium ion or not is neat. I remember when 60 lumens was a pocket rocket

"Moonlight" is 5 lumens. The next mode is 90 lumens. I'll pass

Yea. That's not going to fly with me either. I could deal with the 5 lumen low but 90 for medium is too high. Not enough runtime etc if I needed to hike out using it. Also too much for many uses around the house. But that's just me.

700 lumens from a AA alkaline battery is extremely unlikely. I always look at the math. Since we are working with 1.5 volts, we are going to need a boost driver, and between the efficiency of the boost driver and the wattage required to drive an LED to 700 lumens we are looking at about 5 amps. I wish you luck in obtaining that from a AA sized Alkaline. It may be possible to get it from a NiCd or NiMh which have much lower internal impedance than alkalines. With the lower voltage it would required about 6 amps, so run time at that power level would be pretty short even ignoring the thermal issues. OTOH from an Li-Ion we are looking at about 2 amps. A hefty load for a 14500, but clearly within the capability of many cells, and then thermal considerations would probably be main limitation.

Vinh is getting 700 lumen from a AAA equivalent 10440 cell.
He simply operates in an alternate universe. ;)

Voltage is 4.2 so why not? Then again to what ends given the capacity of that battery. What are those 400 or so mAh? I can get 1000 lumens using a 16340 700 mAh out of a mountain electronics Drop-in running within 1/2 of a Solar Force L2M but to what effect? Dang fun though!!!!!

gunga, you reign supreme in so many ways... honestly, I could not count them all. But what you and all the other poet-warrior flashaholics are in fact after is certainly not a "moonlight" mode, but instead a firefly mode. Moonlight, by the numbers, the actual light intensity that comes from a full moon, is anywhere between 1 and 8 lumens per square meter. Last night's Strawberry moon was at least 8 lumens, if not 10. Abandon the poetry! Be linguistically and scientifically accurate instead! You want sublumens? Its a firefly mode, folks, not a moonlight mode. Thanks for putting up with my repetitive pedantry.

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! :)
