This practical workshop lamp works great. The wide LED array on the front panel can illuminate the work area well, while the LED light casts a rather narrow light cone at the top as Taschemlampe. The lamp requires three AA batteries and works with three AA NiMH batteries! Even with almost empty batteries with a total voltage of only 3V, the LEDs even with nearly full strength. Nice if there was this lamp in a version with a 3.7V-Li-Ion battery.
