This light features a excellent 270° lantern function with RGB, a main beam which delivers a good deal of light for a few seconds and everything is done in very good light quality that reminds me more of neutral than cold white. This considerable feature set is based on a lithium-ion cell in the AAA-format; the light maintains all functions with a lower output based on 1.5V AAA-Alkaline cell as well. The user interface is fitting for a keychain light and simple enough.
