Hmm , i will have to test it.
Edit: About 6.30 minutes . At the 3.30m mark , head is too hot to touch , and in about 3 minutes body is hot too .
Wow, that’s much better than I thought.
Interested as well depending on price. PM me.
Thanks!
Interested depending on price
You got mail. 
I did not receive PM, still interested depending on price.
How long will it run in turbo1 3300lm, before its too hot to hold?
Is Samsung INR18650-30Q 3.6V 3000mAh good to use with this flashlight or do you recommend protected GA batteries instead?
Post 336:
Sorry is this the 3.3k turbo, or the 10k turbo?
I’m going to assume it’s 3.3k…
No , it’s the “10k” turbo , but it isn’t real 10k , but around 7k ? - 8k ? in this version .
Oh, I assumed you meant 10k lumen turbo. 3,300 is kinda like “high” in my mind.
I’m pretty sure giorgoskok was saying the time at 10k lumen since that’s what’s really important.
From that time you can deduce that 3,300 lumen will be much longer than that.
Keep in mind this is only an early test model. The final product might be closer to a real 10k and heat up quicker. We won’t know until the next updated version is built and tested.
Hi, replied to PM with the price, please, put me in the list, interested to buy one
Damn really? That’s kind of disappointing. I was hoping for a real 10k.
Please PM me, freeme.
don’t try to be one step ahead 
Final version will have the advertised output . 
I would indeed want 7000lm-8000lm for 6.5 mins, rather than 10000lm for 1-2 mins.
I’m # 49 on the list. PM me please.
Why not both? 
This guy gets it
Take a look at the writing near the springs on the bottom. It says Manker, why even put the same light out in two brands. I.e. Utorch 02 vs Manker U21.
That said: interested depending on price
Freeme I still haven’t replied a PM yet mate
