Comarison Review: Olight I3 vs Olight I3S {A personal overview}

Olight is a flashlight manufacturer. They used to retail lights under both the Olight and the ITP brands.

Under the latter brand they had a highly regarded single cell AAA light flashlight called the ITP A3 EOS.

In the latter half of 2011 Olight merged the two brands. The ITP A3 EOS was modified and relaunched

as the Olight I3. The Olight I3 has the ability to tailstand which the ITP A3 EOS did not.

Latter versions of the ITP A3 EOS used the Cree XP-G R5 led. This was carried over to the Olight I3.


I bought the Original Olight I3 last summer after reading some fab reviews.

It's a super light but there were a couple of things that I didn't like. The new version is called the Olight I3S and this addresses the two things I felt could be improved (for me :)). There is an additional feature which I really like. There are other improvements which certainly add to the light but which I personally wasn't too bothered about.


What's in the box?

The Olight I3 comes in a clamshell plastic pack. A small split ring is attached to the bases of the light for attachment to a keyring. There is an instruction pamphlet, two spare 'O' rings, a Duracell AAA cell and a small hex key whose purpose is to allow you to remove the two hex bolts which secure the pocket clip in place.

The Olight I3S comes in a rather smart looking plastic box with a foam insert. There is an instruction pamphlet, two spare 'O' rings and a Duracell AAA cell. The Olight I3S also has an attached chain and lobster claw for easy keyring attachment. This is an excellent addition.

Here is a size comparison of the Olight I3, Olight I3S and a AAA cell.

(The I3S is slightly shorter than the I3)


And here are some pics of the inside bits of the two lights and the LED's.

(Olight I3S on the bottom & left).


In use

To turn the light on you just tighten the Head. To cycle through the modes you loosen the head and immediately re-tighten, continuing till the desired output is reached.

The I3 sequence is: low > med > high

The I3S sequence is: med > high > low > med > high > low > strobe

The principle changes that I'm aware of are:

  • A lobster claw keychain on the I3S (instead of the split ring on the I3)
  • A new LED The I3 has an XP-G R5 LED. The i3S has a CREE XP-G2 LED which increases the maximum output, from 70 to 80 lumens. I was surprised to see a noticeable difference, the I3S appearing significantly brighter.

I3S I3

These shots were taken from about 150cm from the wall.

The I3S in these pics looks creamy. It appears noticeably brighter than the I3 to my eyes.

  • Pocket Clips The pocket clip on the Olight I3 is retained by two hex screws and is not reversible.Various reviews criticised this, as the ITP A3 EOS pocket clip was reversible. The pocket clip on the Olight I3S is similar to the clip on the original ITP A3 EOS. It is a push-on/pull-off design. The pocket clip can be reversed and placed at the other end of the main body of the light. This gives you the ability to attach the I3S to a baseball cap, as an improvised head light.

The Olight I3S is on the left.

  • Strobe The I3S now has a strobe mode. To get to the strobe, go through the sequence: med>high>low>med>high>low>strobe by tightening and loosening the head for each mode change. If you don't want a strobe, it's sufficiently well hidden. If you do want a strobe, you've got one! Perfect! Personally I like the option :)
  • Lower 'low' output The I3 puts out 3 lumens. The I3S puts out 0.5 lumens. I really like this lower 'low' as it doesn't ruin night vision. I found the low on the I3 too bright so for me, this is a welcome improvement.
  • A better design for use with keyrings The I3 has a split ring which attaches to a fixing point in the main body, just above the base. This facilitated tail-standing, which was a shortcoming of the ITP A3 EOS. The problem with this feature is that the body of the I3 does not hang vertically but at an angle. This is a design shortcoming which should have been addressed prior to production. The I3S addresses this shortcoming with an elegant redesign which allows tail-standing without compromising carriage on a keyring.

I3 I3S



In Summary

A well thought through redesign.
If you preferred the higher low output of 3 lumen of the Olight I3, then this is still a good light. If the shortcomings of the Olight I3 bug you and the 0.5 lumen output of the Olight I3S meet your needs, then like me, I think you'll love the redesign!

Readers should note I'm very limited on flashlight knowledge or experience.

we have a new reviewer in town.

kicks J's butt!!

;)

:D

Is the higher output visible?
What about your experience with the triangular piece on the keychain?
Someone reported that he lost his i3s because this bend easyly open.

Great review. I’ve got an I3S in mail system being delivered. Can’t wait to play with it myself.

Great review! Now I’m more tempted to get Olight i3S!

But I felt that i3S has way too many modes. And having to cycle med > high > low, in order to get to low just totally killed the moonlight 0.5 lumens “improvement”. What’s a moonlight when you have to be blinded by bright light first?

+1
I also felt like moonlight mode should have been first.

Thanks for the great review! Time to upgrade the itp, I’m afraid.

Excellent review! Thank you for doing this for us. My only complaint is the chain on the new I3S. It is already broken. I had to put a different clip on the light Other than that, it is a very nice key chain light!


Yes the I3S is noticeably brighter on full beam. I was surprised as it's only a 10 lumen difference.
I'm guessing that the manufacturers supplied I3 output figures were exaggerated.
The triangle could bend and allow the I3S to become detached.
It's a small piece of metal. Though, if it held, then the chain could snap,
or the fixing point on the I3S. It's all relative as it's a small flashlight.
I don't have my I3S on my keyring, so I'll leave that for others to assess.

Given a choice I'd prefer moonlight mode first, or programmable.
But to be realistic, it's an inexpensive torch.
If I was the manufacturer, I'd have done the same set-up.
Imagine a random person being handed the flashlight, without instruction on operation.
They would likely figure that twisting the head turned it on.If it came on in 'Low' ,
they would assume that's all it did. By having it come on in medium, this random person gets a pretty usable medium mode light. Which is a good combination of light and cell longevity.
When I use the light, I cover the end, or shut my eyes, till I get to moonlight mode.
I personally don't find this a major issue.


Yep I guess you’re right. Having medium mode first, made it a better interface for those who wish to use this light “as per normal”, and at the same time having the moonlight option. But any random person who picks up this light wouldn’t have bought it for $20 if it comes on super low moonlight mode and thought that’s it! And the person who passed this random person the light would have told them about the modes…

Probably the percentage of users who seeks moonlight mode is just too little… Percentage of people who are flash-a-holics is already so low; even lower for flash-a-holics who would buy the light for the moonlight (like me)

Great side by side comparison :bigsmile: Highlights the improvements nicely.

Good job .

I like my ITP lights and as soon as I see this model go on sale , I will own one .

Thanks for the great review and nice photos. I have one on the way from Fasttech.

I have an ITP A3 in my pocket always & prefer the L-M-H mode order (second M-L-H). …but it looks like they have addressed every other issue with this light very well.

Most notable for me is the 4-5X run time at 20 lumen (10 Hours). This is a light for many who won’t carry anything larger and is all the flashlight many non-flashaholics will ever need. 20 lumen will get you down a trail in the dark and just enough for most close in tasks.

8-10 hour runtime means it can run on alkaline (low enough current draw) and even run for hours on a half dead AAA out of a remote. The A3 is a bit of a battery vampire too, but was hard to take seriously for the short runtimes.

It’s the one you send with your kid to college or put in Grandma’s purse.
It just might bump the A3 in my pocket.

Thanks for the great review and comparison, I like your review style! Awesome pictures and text headings/colors etc. Very easy and pleasant to read. I look forward to any more reviews of yours!

I was looking at the i3 at IlluminationSupply for $14.99 and didn’t know about the i3s until I found this review. Now I see the i3s at FT for $18.95 with discount (thanks LowLumen).

.
Looking at your beam shots the i3s seems to have a more bluish tint.

.
I like how snap-on clip of the i3s can be rotated to align with the attachment point of the key ring. This feature will enable me to have this attached to my keychain and clip the light inside of my pants pocket with my keychain/keys hanging on the outside.

Sounds like I’d need to swap out that weak triangle clasp and chain with something stronger.

I notice the Specs charts here show different battery types (std. AAA for the i3 vs eneloop for the i3s) makes me wonder if the specs/runtimes would be different if both were using the same battery type.

thanks for the review, I’ve never justified a light this small myself but I may have to get one for mrs gords. 8)

Very nice review! Frontpage’d and Sticky’d.

So does this mean that we’ll also be seeing an Olight I2S 1xAA refresh as well? I dig the super low mode mentioned here.

Yes… super review. Nice pics, too :slight_smile:

Thanks everyone.
My next scribbling will be the tiny Essential Gear Pico lite.

Thanks for the great review!
