[Review] MANKER E01 (Nichia 219, 1x AAA)

The manufacturer states Nichia 219C. Even though this spec might not be fully true, in the remainder of the review i am going to employ this spec’ed detail when referring to the emitter.

LED: Nichia 219
Battery: 1x AAA
Modes: 4 (Low-Med-High-Strobe)
Switch: Twisty
Date: March 2016

The Manker E01 is a simple and small flashlight from this new manufacturer, which it looks like we’re talking about a lot lately. Like any self-respecting brand, Manker now offers an “introductory” small and inexpensive flashlight, intended for everyday use or key ring. It is available in various colors. This flashlight is also marketed under the brand Astrolux, which can lead to some misunderstandings.

The product presentation is very similar to what we have seen in other flashlights from this manufacturer, with a small cardboard box in which we find the flashlight accompanied a spare o-ring and a small split-ring for the keychain. It also includes an user manual in two languages (Chinese-English).

The exterior design of this flashlight is quite original, because of its rounded shapes and slight oversizing gives it a very own distinctive aspect.

It is machined in anodized aluminum with very nice matte finish, and has some very well-defined and easy to read engravings thanks to the high contrast obtained between the black background and white graphic. In addition to the brand and model, we have an indication with the correct polarity of the battery as well as another indication of the mode of use, all very basic.

The head of the flashlight has substantially larger diameter than the rest of it, and has a generous strip of knurling which greatly facilitates the grip of the head to make use of the twisty. The bezel is flat, with generously rounded edges.

The optics of this small Manker is composed by a OP reflector and Nichia 219 LED with neutral tint, properly centered, and all topped off with an AR coated glass lens.

The walls of the flashlight, especially in its connection between the head and body have a very generous thick. The driver disk is covered by a foam ring, which prevents the typical battery rattle when the flashlight is off, and in addition it also works as a mechanical protection system against wrongly installed battery (reverse polarity).

The threads are anodized, and arrive well bathed in lubricant from factory, as well as the o-ring. Twisty action is quite smooth.

The tube design is quite peculiar as it has “two volumes” but maintains a smooth design, with smooth curves at both ends. Tail design, also rounded, has a large hole to put the split ring. Machining surrounding it has some sharp angles. Of course, with a design so rounded the tailstand of this flashlight is stable at all.

Dimensions and very similar to the average in this type of flashlights weight.

The E01 has a fairly simple user interface, common with many other popular AAA flashlights.

  • On and off: This small Manker E01 turns on and off by screwing or unscrewing of the head. With fully screwed head flashlight turns on, with head slightly unscrewed flashlight turns off.
  • Changing Modes: To switch between modes we have to make a momentary off, to turn it on again in the successive 2 seconds. The order is ascending: L-> M-> H.
  • Memory: E01 has no memory mode, so after ~10 seconds from off it always starts on default Low mode.
  • Hidden strobe mode: To access the stroboscopic mode we must perform a sequence of six on / off (L-> M-> H-> L> M> H> Strobe).

The three modes of this E01 are separated by great distances. In the user manual referred to as Low mode as Firefly, that with such sub-lumen mode like this that name would have been more appropriate. The Med mode, with 7LM is much more usable, and with maximum output mode we found a small discrepancy between measured by the sphere and specified by the manufacturer.


Performance in Hight mode with AAA Eneloop is quite discreet, with a smooth curve in which most of the time we move between 70 and 80LM.

Compared to other flashlights AAA, this E01 is not particularly outstanding nor maximum output nor for runtime. Click here for a view the image in higher resolution.

In this new feature for my reviews I will analyze the efficiency of each flashlight in a fairly simple way. Taking advantage of the data obtained in the previous runtime vs output test, we can make an estimate of the efficiency in lm·h, which will give us a value equivalent to the area that the line of each flashlight delineates between the X and Y axis of a graph as the one from previous section of this review. Given that all compared flashlights have been tested under the same conditions, using a battery of the same model and the same measuring instrument, we get the following result:

(More details of how this calculation was made here)

We can see in this bar comparison chart how well each of the tested flashlights performs (in a given mode) in the task of converting the battery power into accumulated luminous flux. As expected, the flashlights with a lower regulated output mode, or with drastic stepdown such the E99Ti scores better lm·h results in such test as emitter efficiency is better in that lower output ranges.
In this particular case, the Manker E01 scores a fairly poor result, just above the old and outdated Tank007 E09.

The Nichia 219 is undoubtedly the hottest point of this Manker, since it is difficult to see such emitter in a mass produced flashlight.

The projection is very good with a medium-large hotspot well faded with spill with no artifacts or darker areas in the area surrounding the corona.

Although the Nichia LED is slightly behind at maximum output or efficiency versus CREE alternatives, such the XP-G2, the Japanese manufacturer Nichia emitter offers a higher CRI (Color Rendering Index), so it is able to reproduce illuminated colors in a more reliable way or closer as sunlight would do.

Camera WB: Daylight

Although the flashlight has no special charm beyond the employ of a “gourmet” emitter, I must admit that for the price this is an excellent alternative for those looking for a neutral or high CRI flashlight simple, inexpensive and different from the rest in aesthetic design.

Negatives: The E01 is a slightly over-sized flashlight, with a head that is somewhat larger in diameter and perhaps wasted space. The performance and efficiency of its High mode is poor compared with other similar single AAA flashlights. The spacing of the modes is a bit quirky, and the default activation mode may be too low for most situations.

Positives: Undoubtedly the attractive price of this AAA flashlight is a good point, because it allows us to ponder its acquisition unceremoniously. The chosen LED emitter is in my opinion another plus for Manker, because it offers us a great CRI, hard to find in mass produced flashlights and much less at this price.

Manker E01 provided by manufacturer for review.

Thanks for the great review. The comparisons are useful.

That’s a pity that they made the body too chubby…I guess I’ll have to swap the emitter of my I3S for a Nichia.
Anyway, it looks sturdy and that’s cool to see some 219C in mass products !

I’m sorry to disappoint you, but that’s no 219C.

Soooo what is it ?

NICHIA NVSW219C-R9050 LED according to user manual :???:

Most probably 219B-V1 R9050, not sure about the tint, if it’s quite warm, it’s probably sw40.

In fact, there’s no need to be disappointed, the 219B-V1 is great and offers much better CRI than 219C at this point. Most people overlook it and think it’s 219B, but 219B-V1 is more efficient than 219B and has even better CRI than 219A.

If it was a 219C you’d see some black parts on it. Also there is no R9050 variant of the 219C at this point.

Again, if you were after highest CRI Nichia, you got the right one. But I’m really starting to have problems taking Manker for serious.

So the NICHIA NVSW219C-R9050 LED and 90CRI statements in user manual/manufacturer website is wrong?

90CRI is true. 219C is definitely not true.

If I’m correct on the tint being around 4000K than the LED would be:

NVSL219B-V1 R9050 sw40

Thanks. Next time I contact manufacturer I’ll ask about this matter and share their reply. :wink:

no problem. Again, if you want really high CRI, than this LED is one of the best choices. The 219C?, not really.

Look for the little black triangle in one of the four corners of the LED — that identifies it as the “b” emitter
You can see that in the pictures from Manker, and look it up various places that show images:
219a (four sides and one corner marked), 219b (one corner marked): https://budgetlightforum.com/t/-/27806

and 219c (no corners marked).

Nobody knows what they’re selling.

Great review.

Is this the exact same light as the Astrolux A01 (Nichia 219B), just with different lettering?

It’s no 219B and no 219A, it’s the 219B-V1.

Look at this thread, comment #174, #178, #179, ( #182 ), #204, and the actual proof was #205, where the image is gone. But it showed a 100% proof. I wonder why it’s gone now…

It seems to me a nicer shape and finish than most AAA size lights. It might even be second to the SS-5039 (which has little else in its favor).
The 219C does not necessarily give it lower output than it would have with an XP-G. Unlike a regulating driver, a boost driver will put out more charge at the lower voltage. It is even more efficient with a smaller difference between the input and output voltages and will put out more energy with the Nichia’s lower forward voltage. The fact that the measured efficiency is low is probably due to a less expensive driver or stray losses.
A third generation Osram Oslon Square might have done even better. https://budgetlightforum.com/t/-/38479 Its forward voltage at low current is even better than that of the Nichia.

This review says the Manker has an AR lens. I don’t see that in my Astrolux.

The Astrolux (orange) I got a few days ago does seem to have an AR coating on t he lens.
Nothing special, just a thin film of something slightly colored, not like what you’d expect on a camera lens or binoculars, but it’s not plain glass

Moonlight mode mafia strikes again!!!
Very good job UPz, thank you very much.

The UPz for the efficiency estimates :slight_smile:


Yes, I agree. With such small battery capacity, this is a very helpful chart.
