Good to hear from someone who has over a decade of experience with these products! Thank you for sharing and for checking out the video 👍

Thank you and thanks for watching!

I ran into the same issue with heat and I also just stick with AAAs for this model. Thank you for your testing surrounding the i3E. Your idea to swap components was smart! It’s a mystery indeed but hopefully these videos help in some way.

Nice! Yeah those i1R2s are fantastic! I too like Olight as a company.

I think the issue you had is why they now come with a double o-ring, more to protect against head loss than added water resistance. One tip I read about for the old ones is to use a wrap of plumber's PFTE tape around the threads to keep the head from vibrating loose over time. If you asked for a new head, they might send you one...or just pick one up when they are giving them away for free [$5 shipping if you don't spend $49 on purchases to get free shipping].

Oh wow, that’s impressive!

Indeed! Handy and hardly takes up any space.

Yes, they are responsive and helpful.

Nice! Good to know. I hadn’t tried that yet. That’s another reason the i3E rocks in my book!

@@PardonMyEnglish most definitely, did you know olight sells a pocket clip that snaps on to the rear of the body? I plan on getting one soon cause I'd rather keep mine in my pocket than on my keys

I had no idea!

Nice! The Royal blue i3Es look really good. Yes, I love when Olight gives a free light during their frequent sales/promotions. Feels great to get a quality light included!

@Pardon My English Thanks! Yes I thought that it was a good torch, but to then read someone else who also thinks they are great too is a bonus! 🙂

Wow! That’s awesome to hear!

Sweet! I obviously have a problem with them rolling around 😂

Yeah, it’s an impressive combo.

@MrPsiman thanks for this tip but will it cause heating or other issues ? Please suggest good rechargeable Lithium ion battery

Haha, thanks! I think you’ll enjoy it. I’ve had one on my keys for a while now since making this video. I officially prefer it over the other options (which are also great, in my opinion).

@@PardonMyEnglish I have a stream light polytac for edc, but I like the idea of a small keychain light. It’s more likely to be used on the fly. I don’t always need 600 lumens. Around the house I keep a couple stream light dualies, NiMH batteries so I can recharge, and the energizer ultimate lithium batteries stockpiled for emergencies. I bought one decent flashlight and oddly became addicted. Perhaps I should just smoke drugs it may be cheaper.

Haha, yes it’s funny/surprising how addictive flashlights can be.

Good observation!

Thanks! Glow in the dark is a good idea but I just put a little paint (nail polish) in the grooves of mine.

Sweet, the Regal Blue looks really nice. And good theory about the contacts. Please let me know if those rechargeable AAAs work well for you!

Good theory since I don't see any electronics in the tube to explain the difference. If one looks at the tube the only non-anodized part, to provide contact, is the very end of the tube which is bare, and touches a little ring around the electronics in the head. This as opposed to many flashlights that have a bit more bare area towards the end of the threads. So I suppose that might make battery size/length a critical factor. I have had great luck with hybrid [eneloop or Ikea Ladda] batteries, so for me it is not an issue. I avoid using alkaleaks if at all possible.

Nice! Good to know. I need to look into other options such as the EDC01. I know those LiFePo4 batteries also last for thousands of cycles, so great option.

@@PardonMyEnglish Well I tried the liFePo4 batteries after I found out my OPUS BT-C3100 true delta-V smart charger had a secret switch inside which allows you to set the terminal voltage to 3.7v which is terminal for LiFePo4 batteries. I dremeled out the area where the switch is so I don't have to take it apart to switch the terminal voltage, it has 3 settings 3.7, 4.2, 4.35. Gotta love it when the engineers put stuff in before the bean counters get a hold of a product and neuter it for "profitablilty". 🙂 I get about 5mins less run times and slightly less lumens than a 10440 but 2500 charges until 80% is a small price to pay. It's still 3 times brighter than using a NiMh or alkaline battery with way less heat than a 10440. For regular voltages I use EBL 1100 mAh NiMh batteries and those things rock. It has about %30 more of the mA of your standard alkaline battery and keeps it's voltage right until the end. If you click on my name I think I have a review on them and you can see the Opus in action. I also have a short video with all 3 batteries being used and their brightness levels and run times somewhere in there. Even buying the cheapest ass charger and a 4 pack of rechargeable batteries with pay for themselves many times over. I bought the Opus because I charge a lot of different stuff with different sizes from 10440's to 18650's and some of the funky 20350's, it handles it all and has programmable charging profiles and a battery repair function. I think it was about maybe $35 USD? Can't remember but it wasn't that much money, maybe it's a little more now but no more than $50 and you can charge anything that will fit in any standard flashlights. Open it up and look for the "secret switch" on the right hand side of the PCB board and dremel out a groove so you can stick a pen or pencil in there if you want to charge LIFePo4's. It probably doesn't charge te LiFePo4's perfectly as it doesn't have a specific LiFePo4 profile but they are almost identical and it works just fine LiFePo4's are very tough and resistant to overcharging. They can be safely charged to 4.2v but it's not recommended and may reduce the overall life of the battery but they don't explode like Li-ion or have a thermal runaway problem. You don't want to have a keychain flashlight's battery go into thermal runaway next to your twig and berries...to quote Egon from the Ghostbusters...it would be bad.

Nice mod! That’s probably over my head but I’ll definitely check out your videos. If I had to guess, I’d say LiFePo4 batteries will eventually take over in the flashlight/torch industry in the years to come. It’s a superior battery technology/chemistry. I think you’re ahead of the game, my friend!

@@PardonMyEnglish I'd have to agree with you especially on flashlights that have a non-exchangable internal battery. There are many perfectly good flashlights that end up in a landfill simply because the internal battery has worn out. But if you get 6 times the longevity with only a slight lumen and weight cost it, many of those flashlights would still trucking on today. Also LiFePo4's are extremely safe. You can pop them in a fire and they just melt. There are many You tube videos out there of what happens when a Li-ion battery hits thermal runaway and it's not pretty.

Nice! I think you’ll enjoy the combo! As far as the i3T Plus goes, I have not personally tried 2 10440s in it but others have and it doesn’t work unfortunately. Basically stacking the batteries doubles the voltage to 7.4v and it’s too much for the light.

@PardonMyEnglish oh wow that's sucks that beam would have been awesome!! Thanks for your feedback!!

Indeed. Interesting and strange that the bodies of the lights would differ. Thanks for watching!

@@PardonMyEnglish could be the material used as well. I wonder if they differ from batch to batch.

That’s a good theory. So far, I’ve got nothing. I’m baffled.

I was not aware of the change or those differences. I bet you’re right, something about the body must have been made the slightest bit longer to accommodate the extra ring, perhaps?

@@PardonMyEnglish I think you're right. I Just compared the i3uv to my new i3e and the threaded area on the new one is about 2mm longer.

Wow, 2mm is a big difference on a tiny light! That’s got to be the reason.

Good theory. I have some acetone so I could try dipping the body into it to remove some paint if that’s what it is. I’ll let you know if I have any luck.

It may well be just that. Others also mentioned that some i3E bodies have 1 O-ring, while others have 2.

@@PardonMyEnglish The new i3E models have 2 o-rings. I think that was because if you left the old model on a keychain for a long time without using it, the head could unscrew over time and fall off. Never happened to me, but I don't have it on a keychain. Just heard it second or third hand. I believe the double o-ring is to address this problem. Or maybe they just wanted it more waterproof. ;-) For those with an older model with one o-ring, carried on a key chain, someone said to wrap a piece of plumbers tape over the screw threads to tighten it up just enough that would be unlikely to happen.

Definitely a solid light!

Wow, interesting! Even on brand new lights?

Nice, I’ll check those out! There are so many cool options. I wish I could get them all sometimes, haha. But I already have more lights than I’ll probably need in my lifetime 😂

Good to know. Maybe the voltage is too low, perhaps?
