Thanks for the beautiful pics & review!
After the third hailstorm, I made some use of the hail collected today.
Manker U21, Manker U11, Predator V2.5, 47 quark 123^2
I added the images at the first post.
Here with similar form factor single 26650 reflector throwers:
The compact size, to me, is a big advantage. The reflector I.D. is very close, maybe 1 mm shy of an HD2010, to it's right.
Sweet pics Budda,looks neat on the hail. I wish Manker would offer a BLF discount for us,I would definitely buy it.
My thought too.
If only Manker offers BLF discount, I would jump into it.
Pity there’s also no direct access to Turbo
Btw, nice written review @Budda and plenty of nice pics too :+1:
Thanks guys.
Your feedback is very important to me.
@Bombay: I have not forgot you. I’ll make another runtime graph to answer precisely to your question.
ok, thanks guy
BOMBAY, while I did the test you asked, I got very different results from my runtime graph above: the stepdown is very very low.
The Turbo curve I get now is completely different from the one I got before. I checked the data log from that old test, and I can’t find any error.
However, I tested the first 10 minutes of runtime at turbo 3 times with 2 different cells and got the same results… This can’t be wrong.
After the stepdown at turbo, the output is still much higher than the one high level.
And, coming to your answer: yes, you can. Just switch off and back on the light.
However, as you can see in the last graphic, what you gain is around 10% of output. Such a small gain at 1000+ lumens is something very hard to notice by eye, while the light will have a lot more heat to handle.
The main post has been corrected and updated.
thanks for the great review and graphs. Run Time looks very good with + 1250lumen and 18650 battery, I have cold hands, act as a good heat sink :). I like this type of flashlight, now I use mostly eagle eye x6r xp-l hi, sometimes blf d80 but I think that I have to buy my first Manker light
I have and like very much the Fenix PD40 and this Manker U21 will be a nice addition for a light with more throw.
For you BLF guys, nothing really new is said in this video, but you can still admire the light moving in my hands while I delight you with my english.
Thank you again for both the review and the YouTube video; you impressed me with your excellent English speaking ability.
I really like the interface of it. I like all the designs of manker lights.
So I am waiting for the NW version. 
Hope they will release it soon. I found I’d less than $60 under hkequipment eBay . You can get even lower price with the help of M4D M4X.
BTW Nice review buddy.
Gteat review,i know a few old time modders who dont luke the xhp 35s, and believe to be inefficient, but those apecs are hars to beat in a light that’s hardly longer than a standard C8 . And to be honest i have fried more than that in emittwrs and drivers just in the last week.So heck woth I may regret it in a couple of months but i couldnt help myself and pulled the trigger on it and wuth reviews like this one you guys arent helping my addiction ,lol thanks for yhe great review.
How about runtime with the 26650?
HI Buddah thanks for the great job and graphs ,no i like it but ialso know some well respected mebers dont really care for the xhp,me iam a sucker and i love the idea of such a compact thrower i aslo May God and my wife forgive me spent money i dont have for a Acebeam k70,just because of the ridiculous amount of tbrow these lights have !
Thanks for the updated runtime @Budda
Thanks for support Manker and hkequipment, but our web or eBay cannot offer discount for Manker. Also, our U21 listing for BUY IT NOW (no best offer option). Thanks
My Manker U21 arrived yesterday, I am very pleased with this light.
Thats great to hear sidecross ,o just hot a recording from DHL my U21 and k70 should be delivered on the 14th
