Function: 

The EA45S utilizes 2 electronic switches. One is the power on/off switch and the other is the mode switch.

 

From off:

Press and hold the mode switch for more than 1 second to access Turbo mode. 

Press and hold the power on/off switch for more than 1 second to access Moon mode.

Double tap the mode switch to access Strobe. While in strobe press either switch to turn off the light. 

Press the power on/off to turn on the light in the last used mode (strobe/sos/beacon will not be memorized).

 

From on:

Press and hold the mode switch to access Strobe. Press and hold the mode switch for more than 1 second to cycle through Beacon/SOS/Strobe. Press the power on/off switch to turn off the flashlight.

Press the mode switch to cycle between moon/low/medium/high/turbo modes. Press the power on/off switch to turn off the flashlight.

Press and hold both switches for more than 1 second to lockout the flashlight. Press and hold both switches for more than 1 second to disengage the lockout.

 

Data/Runtime:

I measured .08mA parasitic drain. So cells will be dead in about 1276 days, or down to 50% in 638 days on an Eneloop Pro 2450mAh cell.

 

All throw measurements are lux values taken at 7ft and calculated back to 1 meter (Rounded to the nearest hundred). Ceiling bounce numbers are just simple lux measurements of various lights to compare relative output.

 

 

Runtime Test on turbo:

Ambient Temp: 67°F
Minimal air movement, indoors.

 

 

 During this test there is no external heatsink (a hand or a fan) to pull away heat from the body of the flashlight. You can see how the design of the EA45S pulls heat from the led extremely fast. The heat is well distributed across the length flashlight. There may well be an advanced thermal regulation in the EA45S as the EA45S peaked at 121°F and stayed fairly consistently at 120°F; I need to do more testing to determine whether or not this is the case.

 

 

Pictures:

 The EA45S came in the typical retail box. It got a little squished during shipping.

 

Thankfully, the light was unharmed. It came with a decent little holster, a really nice little lanyard, a manual, and the warranty cards.

 

The holster has all your attachment needs. It's a little rough around the edges.

 

Some shots of the EA45S chillin' in the snow. The mode button has the 4 lines, and the power button has the power symbol. The rubber is slightly raised off the aluminum, and has a slight squish squish before engaging the switch.

 

 

The tailcap is an interesting thing. It's mostly red with maybe a slight hue of lightish red.

 

 The red disk twists to remove the tailcap. Nice double spring at both ends.

 

At the other end we find that nifty little XPL-HI LED that is mostly responsible for the very respectable throw in such a small form factor.

 

 

Comparisons:

 

Here I wanted to show the finish on the EA45S (Left). It looks like they used a different process or perhaps type of coating compared to the EC4S (Middle). For comparison an M170 on the right side. It's mostly just a difference in appearance as far as I can tell. I don't know if one is more durable than the other or not. There might be an ever so slight increase in grippability of the EA45S.

      

 

The EA45S next to it's little.. big.. stocky.. brother? Smile The EC4S utilizes 2x 18650 cells and a massive XHP-50 LED.

 

Apart from the finish, the switch is a bit different between the two. The EA45S switch sticks up a bit more and has some squish in the button before engaging.

 

The EA45S is thinner in both width and depth. It doesn't seem like much, but in hand the EA45S feels absolutely tiny compared to the EC4S. 

 

No threads in the EA45S tailcap.

 

Probably the biggest difference, the smaller XPL-HI LED in the EA45S vs the massive XHP-50 LED in the EC4S. This along with the cells each light devours, puts them in vastly different categories of flashlight. 

 

 

Some variety in the lineup.

From left to right: Thrunite TN4A, Convoy S2+, Convoy C8, Nitecore EC4S, XinTD X3, Nitecore EA45S, Convoy L4.

 

Here you can see just how much that XPL-HI LED makes a difference. The EA45S is much smaller than the XinTD X3 (XML2 LED), but has almost identical throw numbers.

 

Beamshots:

First up a comparison between the EA45S and the EC4S. The EC4S is very much a flood monster. The EA45S is pretty much the opposite as a pocket thrower+.

 

Next up is the Thrunite TN4A (XML2, 4AA), Nitecore EA45S (XPL-HI, 4AA), XinTD X3 (XML2, 18650), and the Convoy L4 (XML2, 2x 18650). Despite using AA batteries and being substantially smaller than the other flashlights, the EA45S really throws out there even among 18650 flashlights. It's also interesting to note that even though the EA45S, X3, and L4 have very different dimensions they have very similar beam profiles.

 

 

 Conclusion:

Simply put the Nitecore EA45S is a fantastic flashlight. Extremely well built and finished with incredible performance for its size. It's even more impressive to see this kind of performance on AA batteries. The fact that it can give great lithium ion flashlights twice the EA45S' size a run for their money is just awesome. Definite recommendation from me. cool

I’ve got first impressions after ~5 minutes of them messing with it.

My father was really impressed with the weight to output ratio. “Really lightweight” and was impressed that it put out that amount of light on AA cells. He’s used my EC4S before and he remembered most of the UI ie long press for moon/turbo.

My grandfather liked the output and really liked that it uses AA. He tends to like a simple UI. He ended up just using the power button and scrolling through modes with the mode button instead of using shortcut long presses from off. He did find the strobe mode and started laughing. Silly

It’s like the ‘giggle maker’ thread. Similar to how I react when I click on 1300lm in a tiny 14500 sized flashlight, or 4000something lumens in a BTU shocker. It’s just so awesome you can’t help but let out a chuckle/giggle/laugh.

It ended up being too bloody cold and windy yesterday to get in all the pictures, but I did take this. I thought it was neat (Perhaps I’m just easily amused Smile ). I found out it takes many variables to all come together to capture this as this was the 8th or so attempt after accidentally discovering it the first time I set it down on the railing.

It’s happening to a few pics on my end as well. I was kind of hoping I was just tired and seeing things… Having a bit of a rough transition to the new forum setup. Some things don’t seem to be working how I used to do them.

Edit: How about now? I went in and edited the code for each and every picture… it was adding some additional unwanted code automagically for some reason. It all looks normal on mobile and desktop for me now. (I took the first picture at an odd angle to try and add a little something. Makes it look really tall and obelisk-like… I might just replace it.)

Edit 2: I’m not seeing any distortion in the video on mobile (safari) or desktop (chrome/firefox). Could you maybe screenshot it?

Well I’m exhausted. Bunch more to add later. Beamshots were a no-go tonight, deplorable conditions.

Please give me a heads up if something isn’t showing up correctly for you. I had to do quite a bit differently this time around so I probably made some errors. Silly

Btw the price from the vendor is pretty fantastic… I’m waiting on a response as to whether or not MAP is an issue before I post any of those details.

I’d be interested in a PM Wink

PS: Have you tried measuring the parasitic drain at the tailcap, with it turned off ? This is where my EC4S is problematic.

PPS: You’re beamshots aren’t showing for me.


It’s on the to- done list Smile . I’m charging cells now; I’m hoping to get beamshots tonight.

From what I’ve read other users have measured something like 550 days for the parasitic drain to drop a cell to 50%.

Edit: I’m measuring .08mA parasitic drain. So about 1276 day to dead, or 638 days to 50% on an Eneloop Pro 2450mAh cell. Smile
Heading outside for beamshots.

Thank for the nice review and absolutely nice pictures Smile

I have this light from 3 month, is a great light, good throw for the size, like a lot the slim factor for a 4xAA power bank.

I have only few complains (the perfect light does not exist yet LOL )
- the grip is not so great even with hard anodizing (with the dry hands I “succeed” to drop form ~1 meter on a wood surface, but all ok)
- the led is not 100% perfect centered (but I didn’t see any bad effects)
- the ATR system enter to fast on turbo mode (just a little warm and immediately steps down Sad )

But like I said, overall is a great light, I love it Smile
Bellow few pics with mine

Great review!!! I’ve had one of these for a while now and it has become one of my favorite, most used lights. Pair it up with some Eneloops and it is just about the perfect package as far as I am concerned.
I think Nitecore hit a ‘Home Run’ with this one.

Re. “Press and hold both switches for more than 1 second to lockout the flashlight. Press and hold both switches for more than 1 second to disengage the lockout.”, does that mean that there is no parasitic drain when it is locked out, since this is not a “mechanical” lockout?

Hi,

I noticed that Kaidomain still lists the SD10 as “in-stock”:

http://www.kaidomain.com/p/S022428.Lumintop-SD10-Cree-XM-L2-T6-4-Mode-80...

Does anyone know if they actually still have these in stock and ready to ship?

I thought that the SD10 had been discontinued?

There is parasitic drain; the light is continuously monitoring to be unlocked while it is in lock mode.

Funny y’all should bring up “parasitic drain during lockout” concerning this light. I got curious about that too after reading about that little Nitecore key chain light thing.
I just started testing one of my EA45S’s back on 19 September 2016.
Here are the results so far.

  • Light Nitecore / EA45S
  • Batteries / Eneloop ‘PRO XX’ AA _ (HR-3UWX min 2400mAh / 11-05-EE) _ Batteries fully charged, rested over 24 hrs. then installed.

Date..9-19-2016……10-3-2016
Time..08:00…………16:10

  1. … 1.387v………..1.326v
  2. … 1.388v………..1.328v
  3. … 1.391v………..1.326v
  4. … 1.391v………..1.327v

My Eneloops are flat, light doesn’t turn on after a few days without using AT ALL! I have tried many sets of fully charged batteries, all dead within few days.
Is my light faulty?

Hmmm, how many days is “a few”? Something doesn’t sound exactly right with it for sure.
The post above yours is what mine measure after two weeks. I am gonna update that post every two weeks or so and see what happens.

Even for Nitecore parasitic drain, that sounds excessive. One tip to pass on: On many Nitecore lights, Once you put the cells in, turn it on for a second or two before putting it in lockout. Seems to cut down the drain considerably.

You don't really need a parachute to skydive. But you DO need one if you want to skydive twice!

That certainly sounds bad. I’ve heard of high parasitic drain with other models, but not the EA45S.

I rechecked mine with my new UT139C DMM, I’m seeing 96 microamps which is a little over a 1000 days to dead cells.

Yep. The same amount of parasitic drain as when the light is not locked out. The lockout just prevents the light from turning on accidentally.
