Review: Nitecore EA4 (4AA)

Nitecore EA4 (NW)


(click any image for extra large version)

Summary

Battery: 4 x AA
Switch: Side
Modes: 8 (Ultra Low, Low, Medium, High, Turbo, Strobe, SOS, Beacon)
LED Type: Cree XM-L U2
Lens: Glass
Tailstands: Yes
Price Paid: $59
From: hkequipment.net

Pros:

  • Uses AA batteries
  • Throws far
  • Tailstands well
  • Neutral white (also a con?)
  • Anti reflective glass lens
  • LED perfectly centred
  • Good quality build and finish
  • Hidden flash modes

Cons:

  • UI not very good (in my opinion)
  • Bezel not flush with head
  • Rattle inside head
  • Tint appears green around hotspot and light purple in the spill (on a white wall)

Whats in the box:

  • EA4 flashlight
  • Holster
  • 1 x o-ring
  • 1 x Nitecore branded lanyard
  • 1 x English and Chinese user manual

Quality and Design:
The overall quality and design is very nice. It is built very solid, the look and feel is about as premium as it gets. Flawless HAIII anodising, square threads, 1 piece design, mineral glass with anti reflective coating etc.

But I also have a few complaints, the first thing I noticed (below) is the bezel isn’t flush with the head. I doubt it is part of the design but many other people report the same. When it is empty and you give it a light shake you can hear something rattle towards the head, when batteries are inserted the rattle is duller but still there. And lastly there is a thin clear round disc/ring between the lens and bezel, on one side it stick out enough to cast a shadow on the bezel. I will include pictures of that later.

User Interface:
The user interface leaves a lot to be desired, I understand the concept but it is a lot more complexed than it really needs to be. 1 click, 1 half click, 2 clicks in 1 second, hold down for 1 second, to access different modes and functions. Some people might see this as a pro but I see it as a con. It has a lock out mode that I quite like and although people complain the low isnt low enough I find it to be very good, any lower isn’t really useful to me at all but if you were using it for close up work about a foot from your face on something white then I might see it being a problem.

Light Output
I would have to say the output itself is very good, very bright and a very nice hotspot. So far (until tonight) I have only used it in my dark room and done some white wall comparisons. Unfortunately the comparisons don’t turn out and the PA40W and EA4 look near identical though the camera at a similar output setting. But with my naked eye they look a lot different.

The hotspot of the EA4 (NW) is slight creamy but close to pure white, surrounding the hotspot is a light green flare that quickly blends out to a very light purple, something you would expect from the spill of a cool white LED.

Other
It is relatively easy to hold but not so great, because of the switch positon you find you hand half way back on it. With large hands its only 2 fingers and a thumb holding it and the body barely reaches 1/4 way down of my palm. If i was to hold it with a good grip my hand would be covering the head (not good for heat management) but turning on and off I would need to shuffle it around in my hand each time.

Sizing comparison below from left to right:
Nitecore EA4, Romisen RC-G2 III, Thrunite T10, Thrunite Ti, Nitecore T2

Below you can see the reflectors, while the heads are nearly identical in size the EA4 appears to have a slightly larger and deeper reflector.

Beamshots:

My phone wasn’t able to pick up anything at all so my sister in-law offered to take some shots for me. It was set to “Star Mode” and thats about all I know. While it was very bright its not quite as bright as it appears in the pictures.

Below pic: The trees that the beams are focused on are about 75 meters away, the trees in the background are about 100 meters away. Although the trees in the background appear to be a silhouette you could see the colour and detail with the naked eye. The image quality also seems somewhat degraded since converted but the quality is slightly better when enlarged (clicked on)

Below pic: The beams are focused on the tree in the background, just short of 100m away, although the pic is deciving making it appear to be right behind the shed but its not even in the property.

I will try to take some more beamshots on the weekend at further distances.

Lastly:
I think I was pretty fair describing the flaws, the beam didn’t even bother me until I started comparing it to my other lights.
Photos are taken with a cheap phone.
If I have any incorrect info don’t hesitate to let me know.

Yeah mine says that too, Ill change it to U2. Thanks.
I have a few packs of Sanyo Harmolattice too, Ill try the later but I don’t think it will change anything.

Hi ezarc, thanks for the review!

As a side note, I don’t think there are U2 NW emitters!
So it will probably be a T6 NW

Correct me if I’m wrong

Its 7:50PM now and still light. It should be dark by about 8:30-9PM and Ill go for a drive and take some beamshots.

Also some of the threads and plastic ring that I was talking about and if anything else comes to mind.

Hmm, I had “XM-L T6 (unconfirmed)” written but it does indicate its a warm U2 on the bottom of the box as well.

Maybe Ill ask Nitecore, I didn’t think they were made either because I have never seen them offered before.

Hank Wang says its a T6 3C. All the boxes say U2 on them. I think you’ll see a sticker covering that on newer batches.

How many lumens ultra-low has?
I think it wasnt advertised at first that this light has ultra low, no?

Thanks for the pictures ezarc. Is there that much difference between the two different lights in actuallity? You must have a very understanding sister in law.

The “ultra low” is 65 lumens, its what Nitecore call it in the manual.

And yeah there is quit a big difference in light output, the PA40 puts out enough light to see pretty much anything in viewing distance.

I prefer PA40 but I’ll try to make myself use the EA4 more and maybe Ill warm up to it a little more.

It feels like the EA4 is made for baby hands (my hand takes up just about the whole handle of the PA40) and thats probably the biggest reason I prefer the PA40 over it, but it does pack a lot of punch for its size.

Star mode is like nite mode. I can’t tell the shutter speed on those because there is no info.

Can it run on on four NiZn cells, or on two LiFePo4 with 2 dummy cells, or a single 14500 with 3 dummy cells?

It sure it will run on 4 NiZn cells fine.

Whit the other batteries you are asking about I don’t think it it would but I could be wrong, its not something I would consider trying.

If it runs on 4xAA it will work just fine on 2xLiFePO4 cells.

Couldn't two LiFePo4 cells be to much? I.e. with a 7135 driver it will run fine off 4 AAs, but two LiFePo4s would kill it. (Since they're 3.4 fully charged)
