Please explain your statement of 10s, is there a review/test showing a drop after 10s?
I see it has “Intelligent Temperature Control” So it will “automatically adjust the output of the flashlight based on current temperature registered in the flashlight to avoid overheating”
So this starts dimming after 10s? Do you know aprox. what it steps down to after 10s?
The run time on Turbo is 45min. (Mfg. specs.)
It’s not budget, but it’s the lowest price single cell pocketable xhp70 production light I know of.
(And the price is even less after BLF discount code of course)
Klarus G20……………xhp70 3000lm…….$98
Acebeam EC50…….xhp70 2500lm………$119
Nitecore TM03………xhp70 2800lm………$129
We need a coupon.
What is the difference between proprietary and normal ones ?
There is definitely one step missing between 650 and 3000.
I ask myself why.
I’m also skeptical about the runtime at that lumen output. If the Nitecore TM03 has a runtime of 45min at 1300lumens, there’s no way the Klarus can output 3000 for 45mins. I don’t think there’s a boost driver that would be efficient enough to reach that level and if it did, the amount of current it would use just to maintain 6v would drain even the highest mAh rated batteries very quickly. I’ll wait to see some reviews before I jump on this one.
After 45 min on turbo it will be melted.
What do you expect of this small light without cooling fins? I am pretty sure it will go into regulation very fast.
The proprietary battery means it is a battery that is specially made for and specifically dedicated to this flashlight, a normal 18650 battery will not operate the light properly.
This is what I dislike about Nitecore TM03.
Agreed, and thanks for pointing that out, somehow in my excitement I overlooked that fact. There needs to be a mode level of around 1200lm - 1400lm.
Out of any other cons this is the worst one, I also have to wonder what they were thinking. I’m not so excited for it now.
Haha, of course I was never expecting it to run 45 min. on turbo, 
I thought about not including that spec. in my reply so someone didn’t think I was. I only included it to inform of the Mfg. spec.
My main question was regarding sp5it’s reference to 10 seconds, although now I’m sure he was merely being sarcastic of the short turbo runtime. 
I fully understand (as everyone should) all of these small pocketable xhp70 lights are designed for only short bursts of turbo.
Guys, I suppose that UI and thermal management are similar to G30, this means that you turn on turbo mode and it will reduce current very slightly while light is getting hot, no steps at all.
…………………
Maybe not perfect, but I’m liking the mode levels better on the Acebeam EC50:
And the Acebeam EC50 has NW 5000k option , a big plus for me that isn’t an option for the other two pocket-able size xhp70 flashlights.
The size of the Acebeam is about the same as an Eagle Eye / BLF X6 but slightly longer (+10mm)
So it’s larger than the Klarus.
It’s compact size is what attracted me to the Klarus.
Yup. I saw the pre-release for this light and was excited at the offer until I saw that mode spacing. Then I wasn’t sure if it would require press to hold as the only option for access to turbo. If this was the case then it would be 100% no go. Good thing at least it can access turbo without holding but it is still ridiculous to have 3,000 lumens turbo and 650 lumens high mode. I’d say at least 1500 lumens for high and would settle for 1,000. Not sure about this light.
Also, Acebeam is soon to release the EC50 V2 which will be 3,000 lumens turbo.
What is the parasitic drain from each switch? - the electronic side switch and tail switch?
i got mine from bg for a very good price
WAFFLE REMOVED AS REQUESTED
i love it
for anyone who wants to know, here’s the dimensions
klarus battery 71.34mm long 26.55mm wide
battery tube 27.36mm wide (inside), 34.49-35.92mm at the base
total depth 81.38mm , depth to spring (uncompressed) 68.37mm
Warning
all the above where taken with a fairly expensive digital vernier, but due to differences in manufacturing may be subject to changes
I don’t think you re supposed to be posting the prices or the code. That’s part of the deal right?
And where it will stops?
On 900 lumens max. Except if use it in Yakutsk. There will be no lumens reduce on turbo, 3000 limens steady output.
Absolutely right.
But how many people even know what is efficiency and boost driver?
Everybody read only specs and cares about numbers.
I am wondering that nobody ask what is color temperature and CRI of led.
And finally, to buy flashlight without full info, review with beam shots and run time chart is to become rabbit for tests by your own will.
