    Smile Olight i3E EOS 6 Colors (Luxeon TX, 1xAAA) Review







    I remember Olight produced their i3 EOS of i-series lights under their own name in 2011. They released the i3S EOS after that. The I3E EOS is the latest 1xAAA keychain light. Six colors (Black, Green, Purple, Blue, Red, Silver) are available for this model.

    Packaging is a small card with features & specifications printed on the front and back. Included in the blister pack is the light with a small split-ring (attached) and GreenMax AAA alkaline battery.
    .
    .
    Manufacturer Specifications from user manual :
    • Using a high performance Philips LUXEON TX LED which has a lifespan of 60,000 hours
    • Paired with high quality PMMA TIR lens delivering a homogeneous beam
    • Maximum output of 90 lumens (colors), 120 lumens (silver only)
    • Powered by a single AAA Alkaline battery
    • Aircraft-grade aluminum body with anti-scratch Milspec type-III anodizing (colors)
    • Easily connects to a keychain or lanyard through a key ring on the lights tail cap
    • Available in bight silver, black, red, blue, green and purple
    • Waterproof IPX8
    • Head diameter×Length : 0.55in×2.38in


    .
    .










    The green color was chosen as a sample for review. The finish is good with no flaws on my sample. There is no knurling. Instead, the light has grooves along the length of the head and body tube. The light has no tail switch (i.e., twisty-style light). On-Off switching single-handed is not easy. The lettering is clear and sharp on my sample.
    .
    .


    The light has 2 parts. The pocket clip is not supplied, but there is a groove-looking clip attachment part at the end of the body.
    .
    .


    The head has a clean looking cylindrical design with grooves. There is a circuit board in the head. The light has no reverse polarity protection function to protect from incorrect battery installation (i.e., you should be careful when inserting battery into the body tube).
    .
    .




    The light comes with a PMMA (Poly Methyl MethAcrylate or Acrylic Glass ) TIR lens and uses a Philips Luxeon TX emitter. Centering is not perfect on my sample, but acceptable (i.e., it doesn't influence the beam quality in real life).
    .
    .


    There are grooves along the length of the head and body tube. Grip is not as grippy as actual knurling would be. I hope OLight could supply the pocket clip, as it not only does help with grip, but also serves as an anti-roll device. There's nothing to stop rolling. If you use the light with a key, you don't need to worry about that, of course. The wall thickness of the body is 0.9mm, it is not so thick for the class.
    .
    .


    The screw threads are square-cut of good quality. It seems threads were not well lubricated. But, screw threads action is smooth with no cross-threading or squeaking on my sample.
    .
    .


    The i3E EOS has a built-in split-ring attachment point on the tail end, and come with an included split-ring, which means it prevent tailstanding. The light has a simple spring at the bottom of the body tube that can be manually removed.
    .
    .
    User Interface

    The UI is quite simple, as the light is a single-stage light.
    Twist the head tight against the body to activate the light, loosen to turn off.

    There is no strobe or SOS mode.
    .

    .
    .
    Measured Dimensions

    .
    .


    The i3E EOS is quite compact in size for the class. It's fairly good size for keychain light. Overall build quality is very high.
    .
    .
    PWM


    The light shows no sign of PWM. I notice there is no buzzing sound.
    .
    .
    Runtime


    The runtime to fall to 10% of its initial output from 30 seconds after the point the light is first turned on (i.e., based on ANSI FL-1) for Max. is as follows :

    The light on Eneloops maintains perfectly flat regulation for an extended period, followed by a dropping off. As expected, Eneloop AAA (900mAh) gives you the longest runtime. Note that 10440 li-ion is not officially supported.
    Alkaline AAAs show also a excellent regulation before dropping off.

    Overall output-runtime efficiency seems very good, as expect for a current-controlled light.
    .
    .
    Beamshot

    1. White door beamshot (about 50cm from the white door) on max. output on 1xPanasonic Eneloop AAA (750mAh)
    - ISO125, F/8.0, 1/25sec, Auto white balance


    .
    .
    - ISO125, F/8.0, 1/100sec, Auto white balance


    .
    .
    - ISO125, F/8.0, 1/800sec, Auto white balance


    .
    .
    - ISO125, F/8.0, 1/2000sec, Auto white balance



    Thanks to TIR optics, beam pattern is the focused hot spot for throw with minimal side spill (i.e., not flood light). The light shows reasonably good beam quality. The overall tint is slightly close to cool white.
    .

    2. 3.5m Indoor Beamshot on max. output on 1xPanasonic Eneloop AAA (750mAh)
    - ISO125, F/2.8, 1/10sec, Auto white balance

    Overall Impressions

    • Very high build quality
    • Fairly compact for this class of light (very good for a keychain light)
    • No anti-roll indentations on the body
    • Physical lockout function (i.e.,head)
    • No reverse polarity protection function
    • 10440 Li-ion is not supported
    • No pocket clip is included
    • Only one output mode
    • No flickering due to PWM and no buzzing sound (i.e., current-controlled circuit)
    • Output-runtime efficiency seems very good
    • Beam pattern is the focused hot spot with minimal spill
    • Overall beam tint is slightly close to cool white

    Thanks for your support and information. If he use 10440 Li-ion cells, he probably won't be able to to use other cells such as Ni-MH and Alkarine. It means he can only use 10440 cells in the light (i.e., the light is driven directly from 10440 due to the fried circuit).

    Thanks for the great review. I bought a couple of these from Goinggear a few weeks ago and really like them. I put one on my keychain and one on my wife's. I really like the single output for this use, too. This light is going to make a great gift option for many flashaholics to give to their friends and family.

    THANKS FOR THE REVIEW!

    I like the light. I got it on the 15th of DECEMBER. It is powerful, nice beam pattern,nice and compact.


    The problem I have been having is that it comes on inconsistently. Sometimes it activates, sometimes it will flicker, sometimes it won't come on until several head tightening attempts! Very frustrating! That started happening within a week. The last TWO DAYS IT SEEMS OK,,,,,,,,,,,,,,not sure what is going on!

    I have cleaned the light a few times to remove whatever dirt could build up in so short of a period of time.

    As long as it keeps working and will be durable...[7 miles/day walking my HUSKY W/ IT ATTACHED TO MY CARABINER!],,,I will be happy!

    Thanks for the review!

    This looks like a nice keychain light. But no low mode! With a single mode it would be better with ~20lm and much better runtime.

    Oh! It is good news for users and prospective buyers. Look like the light has much higher working voltage than expected.

    I'm sorry to hear that. I found my some Eneloops (HR-4UTG : 1'st generation, HR-4UTGB : 3'rd generation) don't work. But 4th generation (BK-4MCC) work just fine. I don't know why some cells don't work. It seems this issue is related to length (4UTG is very slightly longer than newer generation). I'm not sure. Hope yours keeps working well.

    Thanks,,,,,,,,,,,,mine is getting sporadic again! Your tip about different ENLOOP generations may be the reason.......Mine are HB-4UTGB 750mAh,,,,,,,,I guess that is the 3rd generation from what you posted.

    I would guess that the primary batteries[aaa alkaline] are shorter,have to check when I get home!

    Why does no one test lights with energizer ultimate lithium primaries but instead always insist on testing with alkalines?

    Cool Square cut threads


    • The screw threads are square-cut of good quality

  19. The square cut threads look fantastic. Everybody's looking for the square cut threads. Are they really just good quality or can we get some input on that?

    Sometimes I did with the batteries, but it's not easy to get it (or somewhat expensive).

    No, it's not. The light is good value for the money, in my view.

    If screws threads action is smooth with no cross-threading or with no peeling anodizing from their repeated twisting actions, we can say it's good quality. And that is case for all types of screw threads (triangular, trapezoidal, square cut). Also it's good for me to feel with minimum play on the screw threads.

    I've ordered five which should be with me on Thursday. I'll check they all operate correctly and check for consistency.
    For the record I'll have 4 black and one purple.

    Mine works flawless, used it last night for the trip to the car in a dark restaurant car park. Sure chucks out alot of light. Looking in the head of the light, there are two chips right on the edge of the outer contact ring my bet is the batt tube is shorting on one of those chips and causing you issues. Lets be honest theres not a lot of room for tolerances in this thing, and for ever thousand they get right cap gets the one that dosnt !

    That may be true! The strange thing is it took about 4 to 6 days before this started to happen.Now it is basically useless! It is just the law of averages,that is why it is important to have trust in the dealer! Illumns have NEVER failed me.

    It is a great little torch when it works!

    Illumns is sending me another one.That one should work fine!

    I think he is on to something! Although it is too early to tell, I believe that[ outer chips] is my issue. One of my chips- [12 O'clock chip in his photo below][sorry no pics of mine] seems to be further on the edge than it should be,further and slightly outside the edge of the contact ring which probably did cause it to short out.

    My light was completely tightened,,,,I loosened slightly and put pressure on the light, bending and pulling towards me w/ both my thumbs on either piece of the light! Somehow I did something[wore the edge of the chip a bit?!] and the last 20 or so activations have been successful!

    We will see what happens from here!


    Bottom Right pic. on his review,,,,the 12 o'clock chip on mine is NOT inside the CONTACT RING like his is. Mine is on the outside border and slightly outside of the ring.

    I agree. And I was just wondering to myself how much money the world would save if quality lights didn't come with batteries that informed consumers won't use in them. This Olight is $10 so probably a lot of people will be reluctant to use an almost $2 L92 in it, but what about $40 or $50 lights that come with no-name alkalines?
