Memory: Yes
LED Type: 1 x XP-E2  (Cool, Pure White)

Product Link: http://www.tinydeal.com/fenix-e40-220-lumen-waterproof-flashlight-px2aqv8-p-67780.html

 


Pros:

Annodization is flawless

Color match between the polymer battery tube and aluminum head is good.

Perfect pure white tint in the upgraded XP-E2 emitter.

AR Lens and a flawless reflector

Square, lubed polymer threads are smoother than some aluminum threads. 

Instantaneous mode memory

Well designed battery holder 

No visible/audible PWM

 

Cons: 

Noticeable Rattle in large tailcap switch

Multiple coronas in beam

 

 

The UI:

The larger tailcap clicky switch allows for momentary on with a half press (no click) and constant on with a full press (click).

The smaller switch controls mode changing from Low to medium to high. Press and hold for 1 second to enter strobe mode which consists of a repeating fast strobe for 2 seconds then medium strobe for 2 seconds. 

 

 

Runtime Test:

Fairly straightforward test. I have the light indoors with little air movement (air conditioned test area). Measured the output and the temperature over the course of about 3 hours. 

Ambient temp: 76*F

4x Eneloop Pro (Rested 1.36v)

 

Cells measured .93v at the end of the test. 

Quite a nice driver in the E40. There is about a 5% overall output drop over the first ~170minutes due mostly to thermal sag.

 

 

Pictures:


The E40 arrived in the normal padded envelope. Inside the envelope was the flashlight in retail packaging.

 

 

Included in the packaging was a nice lanyard, replacement tailcap boot, an extra O-ring, and the E40 manual.

 

 

You'll notice a superb finish throughout the flashlight. I could find no faults even during my fine-tooth-comb inspection. No sharp edges. No machining marks, scratches, chips or defects under the anno. Really well done.

 

The only thing I could pick out was perhaps a slightly shinier finish to the polymer battery tube compared to the finish on the aluminum head.


Very impressed by these threads. I was a bit worried it might have the issues the starry light AA light has, but thankfully it does not. The square, lubed threads are perfectly molded and thread into the head better than a LOT of the aluminum threads I've handled. No issues with play or seating here. The O-ring is spot on as well.

 

The battery holder is very well made. Raised thicker contact areas should prove much longer lasting than the budget version (like the SRK). The batteries are lightly snapped in place. The holder has a groove on one side that makes it so the holder can only be inserted in the battery tube the correct way. The switches are integrated into the battery carrier.

 

Here's a look at the switch caps.

 

 

Mini Breakdown of the head:


The underside is what I thought to be just a contact plate...

 

... but it is actually a bit more than that. It's a really odd design choice. As far as I can tell the only real thermal management from the emitter is a thin layer of metal (the gold part) on top of the pcb contact plate.

 

This is what the pcb/emitter deal is screwed onto. A 3mm thick contact plate with some thermal paste between the two surfaces.

 

Here's the AR lens, pink hue.

 

Perfectly centered XP-E2.

 

 

Beamshots:

 

Here you can see the multiple coronas. If you look very close you can see the spill outside of the Hotspot and double corona. In order to show what the multiple coronas looks like in person I had to drop the exposure way down which essentially eliminated the spill, but in person the actual beam has a rather large spill. Note that this double corona is really only noticeable while white wall hunting within ~7 feet.

 

E40 at 50 yards. Low - Medium - High

 

Solarforce L2i (3AAA), Fenix E40, Mini-A60, Tangsfire C8, Jacob A60.

 

Here I wanted to show similar emitters. XP-E2 is a bit of a rarity in my collection, but I do have several XR-E lights. I included the XML2 C8 in order to show a really common light. It's definitely not a fair comparison considering the XML2 is being driven at about 4amps by an 18650 cell.

You can see the E40 has a wider beam compared to the very throwy A60, which I have a love/hate feeling about. The Jacob A60 is really cool for an inexpensive super throwy light, but the beam is really unusable imo. I have to use a wider light to see exactly what the A60 is aiming at.

 

 

Conclusion:

The Fenix E40 uses an XP-E2 and has a fairly throwy beam, but the hotspot is big enough that it is very usable. I've taken it out into the fields and backyard for the last few days. Its peak usable distance is roughly in the 75-100 yard area. It does a very good job of illuminating a wide enough area in my backyard (80 yards) that I can keep track of the dog's movements no matter where they go, and I can rapidly find them if I happen to get distracted for a bit.

 

It does everything I look for in a light of this size with the added bonus of using very common, easily sourced AA cells. High quality and great performer, 5 out of 5.

Thanks for the review.

I did not realise that the E40 uses a xpe2, the usual choice in this size light is xpg or xml. I like it, it makes for an unexpected thrower Smile

I like 4AA lights.

And I've been considering this one, as well as the LD41. 

Thanks for the review.

I’m guessing no or you would have pictured it but do you happen to have a starry light SA-22 you could picture it next to or compare it to?

I have afew E40 lights and acouple of the LD41’s both good lights but i preffer the LD41 for it’s spill. E40 is a good car light for me living in a rural area a good thrower is useful. I have played with the idea of modding my E40’s with XML U2’s.

compares the LD40 vs LD41 but gives a fair idea of the beam patterns.

good outside beam shots right at the end of the video, the E40 colour is more like the LD41 than the LD40 in the video is the XP-G R4 neutral tint one.

I have another LD41 enroute at the moment got it off eBay

FENIX LD41 Outdoor LED Flashlight 520 lumens Cree XM-L U2 US $59.90

-Item number 111369346692 seller vladimirbest only 1 left Sad – now sold

FENIX E40 Outdoor LED Flashlight 220 lumens Cree XP-E R4 Item number 111376867607 Price: US $39.99
you want an LD40 better grab it quick as they are discontinued now, but the LD41 is better

Wow that’s a lot of quad AA lights wolf. Smile as far as the modding would go… I’m not a creative person I can’t begin to come up with a way to swap in an XM-L, but an XP-G2 would be easy as pie.

Unfortunately I don’t. Sad I almost went in on the BLF version, but something about it wasn’t ideal for me, I think it was the mode setup.

nothing wrong with plastic lighter and cheaper than aluminum, dropped the E40’s god knows how many times and it just keeps work and shows little wear and tear. As long as it looks ok and does the job i am good with plastic bodied lights also remember both are towards the lower end on cost. Both where about half the cost of the LD40 / LD41 /PA40.

JETBeam PA40 has a Carbon Fiber Reinforced Composite ( CFRP, CRP, CFRTP ) body and is about $70.

edit:

maybe wrong on the weight thing

According to the digital scales in the kitchen

ld41 183-grams
ld40 187-grams
E40 169-grams
D40A 167-grams

all without batteries add 120 grams for 4 x eneloops cells

Just for Cereal_killer some more Flashoholic porn :bigsmile:

My new LD41 just arrived so unpacked it and took some pictures with the E40 and the Starry.

Jerommel will be pleased to learn that the Fenix LD41 has an aluminum body Big Smile

Thanks for those shots. Which do to prefer between the three?

Between just the SA-22 and the LD40 which is the better value to give a muggle?

LD40 is now discontinued but you can find afew still on Ebay.

Between the LD40/41 and the SA-22, I would choose the LD40/41 because the interface is very simple and easy. One button selects your level and another is on/off/momentery.

Purely on money SA-22 wins, I bought mine as part of the group buy and like it, but the none flashohilic family members do, they try it once and put it aside. I would have bought a case full but none flashoholics seem not to like it saying the interface sucks and it feels to slender in hand.

While the Fenix lights they play with and like I have bought 4 LD41’s for the family and 3 x E40’s. The family likes the interface and how the lights feel in hand regardless of being metal or plastic.

For EDC my family carry the LD25 and E11 as backup.

The single LD40 i have was grabbed by my sister and she refuses to part with it even when i offered to swap for an LD41. I suspect more to piss me off than for any other reason.

Another possable option is the D40a, it has a similar 2 button interface just a different form factor.

I would avoid the Nitecore EA4, in my family it has been relegated to spares draw oblivion as well as the SA-22.

I will put in an FYI here the E40 is not supplied with a holster but the LD41 holster fits fine and can be bought for about £5/$8.
Also you can buy spare Battery Carriers for the LD41 for about £8.30/$14.10.

I use http://www.myfenix.co.uk/ :Disclaimer i am in no way connected with this company, there that should settle the PAW’s

LD41 Caddie fits the E40

Disclaimer while i have tried this i did not use the turbo setting for more than 30 seconds

If you have lost or damaged the battery caddie for your E40 i will point out that the LD41 battery caddie will fit and it will give you an extra level as the control circuit i built into the caddie. The E40 caddie will not fit the LD41 and the heads are not interchangable before anyone asks

Cree XM – L (U2) LED

Digitally regulated output maintains constant brightness

Low 5 Lumens runtime 160h
Medium 80 Lumens runtime 20h
High 190 Lumens runtime 7h 30min
Turbo 520 Lumens runtime 2h 10min
Strobe – 520 Lumens
SOS – 80 Lumens

Runtimes using 4 × 2500Mah Ni-MH battery
From experience using duracell/procell AA leads to piss poor runtimes and performance.
Using Non-rechargeable Lithium primary Batteries less than ideal but OK.

The LD41 will automatically enter into the High brightness level from the Turbo brightness level after a 30 – minute working time with the security setting. So the runtime of the Turbo brightness level is an accumulated time, not continuous.

The newest model is claiming 680 lumens with the same LED I am trying to find a caddie from the updated light to see it will push my older ones higher . as a cheap upgrade.

I am not connected to myfenix.co.uk except as a customer, best prices i have found for consumable fenix spares. If you know different please post a link.

Update emailed Fenix and they replied:

“Gen 1 520 lumen version had the semi transparent carrier and the newer 680 lumen Gen 2 model has a white carrier”

so i got the Gen 1 520 lumen bugger :_(
