Fuzzylogic, I really appreciate your insight! It is configured! One other observation I have is that when I’m measuring current draw from a NiMH, the current is >2.5A but with a Li-ion 14500 (Sanyo or Windyfire), the max current is ~.95A. this all seems backward! Given the warm tint and floody nature of the beam, it’s hard to tell & I question if I’m getting within 100 lumens of the spec’ed 800 lm with Li-ion (???). Can anyone explain this current read ‘reversal’?

Broodmaster,
I was doing some researching into Li-Ion battery safety (i’m pretty new to this stuff), and was worried about my Sanyo UR14500P being used in the E11 (the Sanyo I discovered is ICR (per Sanyo data sheet), the least safe kind and is not good for higher than 3A constant usage (per Mountain Electronics where I bought them from.)).

Long story short, there’s a review of the E11 on the German site TLF where the power consumption was tested and NiMh was twice that of 14500
http://www.taschenlampen-forum.de/threads/manker-e11-review-1xaa-power-e...

Also there’s this review of the Utorch UT01 which is a clone of the E11 so it should have the same specs, and at high setting, the NiMh was 4.2-3.3 amps and the 14500’s was at 2.01-1.9 amps (the Sanyo is safe, phew).

I’m know next to nothing about Li-Ion batteries so I trust these review by people who know better. I believe it has to do with the fact that the 14500’s have a higher voltage than the NiMH.

Hope that helps a little.

Wow! I was looking for something on the modes of this light but you really did the research! I like this light even more now!
I compared my DQG Tiny 26650 II high mode with high on this light and it did look brighter than the Tiny. At least I know it’s above 500 lm. From some of the posts I’ve read about quality issues with Manker, I wouldn’t be surprised that the output isn’t what is stated. But, comparing ‘Chinese lumens to Chinese lumens’ I think I’ve been able to assess the light’s performance.
The way I understand Li-ion capabilities, if the battery can’t push a high current flow out, you just get a slightly dimmer output. I’ve tested all my laptop pack pulls with the Tiny so I label them based on their max current drain and match with the appropriate light… XP-G2, XM-L, etc.

Just doing some checking of flashlight performance of various lights, in particular the light beam angles. I've found what appears to be a discrepancy in published values of maximum Lumen and/or maximum Candela for the Manker E11!?

 

Light beam angles are usually calculated using the Lumen and Candela published values, but can be calculated based on Lumen and beam throw values also.

 

For the Manker E11 -

using NiMH AA battery > 400 Lumens, 1500 Candelas, calculated light beam angle = 33.5°

using 14500 battery > 800 Lumens, 2500 Candelas, calculated light beam angle = 36.7°

 

That is a substantial discrepancy in light beam angle! Beam angles do not change due to different battery/cell chemistry being used.

The calculations were triple checked, so the discrepancy MUST be due to inaccurate published data (Lumens and/or Candelas).

 

If Manker representative reads this, maybe Manker can provide the correct maximum Lumen and Candela values for both the NiMH and the 14500 cells?

Probably just rounding to the nearest 100 for nice round numbers.

No response from Manker (yet)!?

Yes, the published data is most likely to be "rounded" (up) to make the values look better. But the rounding seems to be a little too generous, perhaps?

 

Just received a Manker E11 NW (Neutral White) light (courtesy of HK Equipment).

First thing I noticed was how small the light is compared to my iTP SA1 lights! Smaller than I expected.

Without reading the user guide/manual I was able to use the light intuitively, which is good!!

 

Not so good, initially, was the light didn't respond on occasion when the light switch was pressed! But fortunately that switch issue seems to have "gone away" after using the switch/light for awhile. This had me worried for a bit as I'm aware that E11 copies/clones such as the Utorch UT01 and the Lumintop EDC05 lights often have switch related issues. And as far as I'm aware there are/were no reported switch related issues with the E11 light.

 

The light beam is fairly smooth with a slight yellowy tint. So this is strictly not really a "neutral" white light, but not far off it.

 

Overall fairly pleased with this light so far. The only slight concern could be unintentional activation when carried in the pocket (or where ever) as the light button can be pressed fairly easily. There is no electronic "lock out", the only way to lock it out is to unscrew the tail cap a bit before carrying the light.

"The light beam is fairly smooth with a slight yellowy tint. So this is strictly not really a "neutral" white light, but not far off it."

This was my first XP-L light and it has the warmest tint of all my lights. For me, preferable for use up close. It is quickly attached to a cap for headlight use.

I carry this light every day and I almost forget about it but it performs when I need it.
