Ordered from the experience with my other LED (T 6) Flashlights equal the set consisting of lamp, two batteries and charger. The operation of the LED lamp with battery delivers higher luminous efficacy than with batteries. The bulb is small and handy and fits in every pocket of my work jacket. Indispensable for craftsmen, in my opinion. However: The lamp (or the battery) will be warm during continuous operation! For a point deduction. Otherwise: strong buy recommendation for all, in dark corners like the engine room, basement, etc. the "rumkrauchen" often times have to!
