Keychain Flashlights to Light the Way
Olight i3E EOS
The Olight i3E EOS is a compact, powerful keychain flashlight designed for everyday carry. It features a high-performance Philips LUXEON TX LED and a PMMA TIR lens, delivering bright, focused light that reaches a considerable distance. Powered by a single AAA battery, it offers an extended runtime. The twist-head activation ensures easy operation, while its anodized aluminum body provides impact resistance and waterproofing for durability in harsh conditions.
You get a maximum output of approximately 90 lumens. Its runtime with a single AAA battery is around 16 hours on the lowest setting. This combination of brightness and longevity makes it a reliable choice for everyday carry. The Olight i3E EOS is lightweight and small, ideal for keychain carry, emergency lighting, outdoor use, and everyday convenience.
The Two Sisters
Olight and Osight are sister brands belonging to the same parent company but operate independently. Olight focuses on mobile lighting products like flashlights and tactical lights, while Osight specializes in firearm aiming devices, particularly red dot sights. Osight officially began in 2021 in response to customer demand for high-quality, affordable optics, and it launched as a separate brand in 2025. So while they share a connection, they have distinct product lines and brand identities.
I got the Osight version of the Olight i3E EOS at SHOT Show 2025. It’s a compact, powerful keychain flashlight nearly identical to its sibling. A AAA battery powers it, and the twist-head activates it.
While this might be a promotional item, Osight might add it to its lineup, which covers everything from firearms to EDC keychain carry! Either way, it will light the way!
Thrunite Ti2
The Thrunite Ti2 is a compact, durable keychain flashlight designed for everyday carry. Made from aerospace-grade aluminum with a hard anodized finish, it offers excellent resistance to wear and corrosion. It features a CREE XTE LED, producing a bright, focused beam with a simple twist-head activation for easy operation. Powered by a single AAA battery, it delivers reliable performance with an impressive output of 120 lumens without needing onboard charging. If this doesn’t light the way, check your battery!
This flashlight is ideal for keychain carry, emergency lighting, and outdoor use, thanks to its shockproof and waterproof design. Its lightweight and small size make it convenient for daily use, ensuring you always have a dependable light source!
EDC Travel
This little gem has been on my EDC Griffin Pocket Tool EDC key fob for about three years and counting. It has been to several countries and has illuminated my backpack, airplane aisles, and the streets abroad while traveling. It is durable and doesn’t eat up your battery like a hungry hippo!
Streamlight Microstream
The Streamlight MicroStream is a compact, reliable pocket flashlight designed for everyday use. It features a C4 white LED that delivers 45 lumens of bright light with a 41-meter beam range. The two-way pocket clip allows for secure attachment to a pocket or a hat, providing hands-free lighting when needed. Powered by a single AAA battery, it runs for 2.25 hours, making it a convenient and efficient lighting tool for daily use.
Lighting Up Camp
This is my go-to light for camp and outdoor hikes. However, it’s a battery eater. I love the convenience of the push button, spot checker light when walking short distances, or answering nature’s nighttime call. It’s large but bright, reliable, and easy to feel in the dark. While it’s not as mini as the others, I won’t camp without it!
