The Brightest Keychain Flashlight (300 Lumens)

by Justin Thomas •

In A Nutshell

  • The brightest keychain flashlight is the Titan Plus by Surefire. It produces 300 lumens on its highest setting. It costs about $90. However, it is 3.375″ long — almost too long for a keychain (see photo below).
  • The brightest compact keychain flashlight is the ThruNite Ti3. It costs about $36.

The Brightest Keychain Flashlight: Titan Plus

I received this flashlight, and it’s very bright and solidly constructed. However, it is larger and heavier than I expected. I am going keep the ThruNite Ti3 (see below) on my regular keychain. I’ll use the Titan Plus when I go on longer excursions.

All Surefire flashlight are designed and built in the USA, although some components are still sourced outside the US. Surefire says:

We do import a few components – most notably, the finest light emitting diodes (LEDs) from top-notch manufacturers outside the country – to incorporate into our products. All of that said, we do rely on as many American-made parts and components as possible, and the assembly of these components is done under our watchful eye in the U.S. to ensure optimal quality.

The Titan Plus is available from Amazon for about $90.

The Brightest Keychain Light Under $50

The Brightest Keychain Light Under $20: Thrunite Ti3

The brightest keychain flashlight for under $50 is the ThruNite Ti3 which shines with 120 lumens in its highest mode. This is a very small light — it’s only 2.76 inches (70mm) in length. It’s body is a titanium alloy, and at 0.56 ounces (16 grams) it is also one the lightest keychain lights.

The ThruNite Ti3 uses just one AAA battery, and costs about $36. It’s fully IPX-8 waterproof — it can be submerged up to 2 meters.

Here is the ThruNite Ti3 in action on its highest mode:

Personally, it’s all the light I need to travel through the forest at night.

One negative for me — when the Ti3 is first turned on, it starts in “firefly” mode (.5 lumens), and it requires a couple of more twists to get it to”medium” mode (12 lumens). However, if you keep the light off between 2 to 10 seconds and then turn it on, the light will turn on in the last mode accessed, thankfully.

The ThruNite Ti3 is available at Amazon for around $36.
