Review of Manker U21 - 18650/26650

nice review,enjoy it.

Very good review!

It seems, and this is good, that the UI is the same as the U11. So if you have a U11, here is the thrower to compliment it…

The price is not bad, considering the XHP35 and a boost driver, plus the nice looking finish and fit….

great review Budda!

molte grazie

Fenix PD40, by comparison, works with 26650/18650 battery, has an MTG2 at 1600 lumens. It comes with an holster, but is not rechargeable and there is no tint choiche… has an MSRP 100$ on some known chinese websites.

65$ seems to me a competitive price, as an MSRP

Great review! I like the flat runtime graphs. Regulated at 900lm is nice.

Tha KS for the review, kinda want to get this light when it becomes available in NW. As for measuring the charging current, Xtar makes a USB amp meter that you plug inline between the power source and cord.

Sounds really nice. But where is it available (maybe with a good deal)???

nice review, thanks
that design and finish look very nice!

Nice Review! I received one as well for review. May take me a couple more days, mine performs similar in output on a EFEST IMR 5200 cell.

Disappointing about the stepdown when the light is driven at spec. Also, no tactical momentary on-off feature. I hate press-and-hold UIs. But still, looks and sounds like an impressive light.

Thanks for the review. Would it be possible to pop the driver out to see if a resistor mod could be performed to increase current? Also, is the LED sitting on an “integrated pill?”

Thanks again,

On mine, the driver appears to be epoxied in, similar to a soft thermal epoxy you find under many MCPCB's. Notice in the OP picture, there's no driver retaining ring. When you remove the bezel, it gives access to a really nice 28 mm MCPCB that appears to be copper DTP, but not sure. But no easy access to the driver from the bezel end. So, possible way to pop out the driver is via the switch hole (like an SRK), but from past experience, you can risk damaging the driver by trying to force the driver out by breaking the seal of the epoxy.

For me, I might try drilling out a hole on the edge of the driver, and use leverage from a pry tool. Not sure how resistor mods work with a well regulated boost driver. Also the turbo stepdown cannot be disabled, most likely.

Thanks for the review. The clear pictures are a great help.

Thank you guys for the feedback.
Soon I should get my hands on a 26650 and update the graphic.

Wait new data base on 26650

Thanks for the review - is the tint really that greenish? Looks almost like those early Javelots with their dedomed XP-L´s …
Too bad for the harsh stepdown to 60% (after 2 minutes I suppose?) I hoped for a thrower without stepdown.

Cheers,
K.

Budda, as You clearly have access to both U11 and U21, why not make picture with both those lights for relative size comparison?

@Kusie
My eyes are very used to warm tints (almost all my lights are under 4000K).
I don’t know why the camera shows the beam a bit on the neutral side.
The tint is a CW, but not too cool.
The XP-L with greenish tint I believe are the one “custom dedomed”. The XP-L Hi and the XHP35 Hi are produced dedomed by CREE, and so the tint is fine.
A light without a stepdown is a light without a turbo mode. Turbo mode is something that you should use for a short period of time.
The turbo mode can differ from light to light, for a small AA battery may be 500 lumens and for a triple led copper light may be 3500 lumens, but the principle is the same: this mode will push the components to the limit, and for the sake of the light, this mode is limited.
My advice is: if you need a 100’000 Cd light, choose one that have this value at hi mode, not at turbo mode. Thus you will have the amount of throw you need with no stepdwon.

@Altonx
I will make pics, but the size are quite different.
I’ll throw in some other lights to compare, bigger than the U11.

turbo stepdown can be reset after the off-on switching ?

Thanks for the beautiful pics & review!
