Compact keychain flashlight for everyday carry

The Coast KL10 is a pocket-sized LED light built for quick access on a key ring or bag clip. It delivers 100 lumens of fixed-beam flood lighting in a black aluminum body that weighs 0.8 ounces and measures 2.9 inches long. The twist-on activation keeps operation simple when you need light fast.

Twist-on operation with IP54 storm-proof seal

Rubber gaskets protect the internals to an IP54 rating, so rain or splashes will not stop the beam. A single AAA alkaline battery is included and slots in from the tail; the threads seal the compartment when tightened. Over-tightening can make the next opening stiff, so stop once resistance is felt.

100-lumen fixed flood beam reaches 36 meters

The non-adjustable flood pattern throws usable light to 36 meters for up to 40 minutes on the supplied cell. Buyers who need a focused spot beam, longer runtime or rechargeable power will need a different model. The fixed output suits close-range tasks and emergency signalling.

Questions about this item

How do I verify the 100-lumen fixed-beam flood is working after twisting it on?

Twist the head to activate the light; you should see a steady, even flood beam reaching about 36 metres and running for roughly 40 minutes on the included AAA alkaline battery.

What comes in the box and do I need to buy anything else to start using it?

The package contains the KL10 flashlight with a keychain ring already attached and one AAA alkaline battery installed, so no separate purchase is required.

Which version should I choose if I want the smallest aluminium model that still gives 100 lumens?

The KL10 is the only 100-lumen aluminium keychain light in this series, weighing 0.8 ounces at 2.9 inches long with an IP54 storm-proof build.
