A small EDC flashlight that you can carry around. I put a small aluminum carabiner on the included strap so that the flashlight can be attached to a backpack loop, a backpack pocket key holder, etc. I usually use the lowest or second lowest light output. Red is also good if you wake up at night and go drinking, etc. so you don't wake up others with the light. Red light preserves your night vision - I often use this if I wake up at night.
Please note that the key lock can be turned on by pressing the switch for a long time, which results in: white light - red light - flashes 2 times, which means the key lock is on and the light does not turn on, e.g. in a pocket. The key lock is turned off when you press it long enough that the white light turns on.
I have bought 3 of these. both for myself and for family members.

Really handy for car keys. Lightweight, super good light and easy to use and charge. I recommend it, it's comparable to even bigger lamps.

"A great" small and efficient lamp. Gets a little hot but not too much.

Very high quality and bright. The downside is that the metal shell is cold outside in the winter if you use it without gloves.
