The i5R EOS is the rechargeable version of i5T EOS, one of our most popular tail-switch EDC flashlights. It adopts a customized 1420mAh Li-ion battery with an integrated USB Type-C interface for charging. The high-performance LED, paired with a PMMA lens, produces a soft and balanced beam up to 350 lumens. Like the i5T EOS, it features a tail switch, aerospace grade aluminum alloy body, unique double helix knurling, and a two-way pocket clip. The i5R is the perfect upgrade with higher performance and a rechargeable design.


1. Q: What charger can be used for i5R?

A: The I5R uses the USBA-C charging cable (shared with the Open 2 charging cable)

2. Q: Is i5R compatible with other batteries? Will there be any effects?

A: The product is compatible with alkaline AA, Ni-MH AA, and lithium-ion AA batteries. When using these batteries, the maximum brightness may not reach 350Lm, which will not affect the use.

The I5R can only use batteries with a voltage of no more than 2.6V, so it cannot use 3.7V 14500 batteries.

3. Q: Are the batteries of i5R and I5T interchangeable?

A: i5R can use the battery of i5T, i5T cannot use the battery of i5R.Because the i5R battery has a higher voltage (2.7 volts instead of 1.5 volts) than the i5T, the led chipset will burn out on the i5T. The i5R can however run the AAA battery (If a bit dimmer).

4. Q: What is the material of i5R's body?

A: The i5R is made of AL6061-T6 aluminum alloy.

5. Q: My i5R becomes hot on high mode, is this normal?

A: Please don't worry, it is normal that the light will become hot on high mode, usually no more than 50°C. Besides, it will downshift automatically if it has stayed on high mode for more than 10 minutes, which ensured safety.

Handy EDC light. It’ll be getting carried daily

Color: Rose Red Gradient

I use my lights for #O-EDC and #Camping; I enjoy the #I5R and #I5TPlus for a more compact back pocket carry, and the #Baton is nicer for a belt carry. The #O-Pen is a great addition for a small flood style light, and the #Obulb is a camping favourite

I work in the Healthcare industry at one of our local hospitals. I have carried an Olight for the past four and a half years, on a daily basis I use my I5R (I5T) to quietly check in on patients and not disturb their rest and recovery by turning on the overhead lighting. My daily carry has made my job so much easier qnd made my patients so much more relaxed. My Olight has been such a overwhelming hit in my department that my husband and I have had to gift one to all my coworkers. #EDC

#i5R The i5R is the perfect light to keep in a perse or handbag. It’s bright enough to light up the path back to your car after dark and with the rechargeable battery it makes it perfect! The i5R is a great little flashlight!

As you can tell my favorite Olight has to be the i5t/r... They are super handy for everyday carry and seem to be finiding my pocket almost everyday. Love the size and all the different color options to compliment the loadout of the day. A very close second would be the Seeker Pro line for camping, and the Obulbs which get a lot of use with the kiddos. Thank Olight and Olight Team for the great products and service!!
