Everyday Carry Light

The NICRON K11 is a rechargeable keychain flashlight weighing 16 grams and measuring 2.48 by 0.6 inches. It delivers up to 400 lumen from its main emitter and includes four distinct light types: white, warm, UV and red. The cylindrical plastic body carries an IPX4 water-resistance rating and one-metre impact resistance for daily carry.

Four Light Types & Recharge

Eight selectable modes cover low, medium, high and max white output plus dedicated warm, UV, red and red-flash settings. A built-in 300 mAh lithium-ion cell powers the light for up to 11 hours on the lowest mode. Charging status is shown by a switch indicator that glows red while charging and turns green when full.

Check Compatibility First

Verify that a keychain or clip attachment point suits your intended carry method on bags, clothing or keys. Confirm that IPX4 splash resistance matches the wet-weather exposure you expect. Ensure the maximum 400 lumen output and 11-hour low-mode runtime meet your brightness and duration needs before ordering.

Questions about this item

How long will the built-in 300 mAh battery last before it needs replacing?

The lithium-ion cell is rated for about 11 hours on low mode; recharge cycles will gradually reduce capacity, so plan on a new unit when run-time drops below your needs.

What stops the 400 lumen output from running continuously?

Heat buildup in the tiny 16 g body triggers thermal step-down after a short burst, so max brightness cannot be sustained.

Does the IPX4 rating mean the light stays cool during all-day use?

IPX4 only covers splash resistance; the plastic shell still gets warm during extended high-output runs, but normal mixed-mode use stays comfortable.
