The Ingo Maurer B.Bulb is a portable table lamp with a rechargeable battery. The lamp can be recharged with the supplied USB-C cable and then operated wirelessly. The lamp can be switched and continuously dimmed via a push button dimmer under the lamp base. Briefly pressing the dimmer switches the table lamp on or off. Pressing it longer dims the light. With a memory function, the last set light intensity is saved and automatically set again the next time the lamp is switched on. When dimming the light colour of the integrated LED changes to a warmer tone due to the dim-to-warm technology. The colour temperature changes from 2,700 Kelvin extra warm white to 1,800 Kelvin extra warm white. The B.Bulb is based on the world-famous 1966 design of the Bulb and emits its light evenly and glare-free in all directions.
