The Einstein 750 is a part of Nebo's new line of head torches, named after the famous physicist Einstein!
The dual white LEDs output a bright beam of 750 lumens on the turbo output, which is designed as a boost setting, allowing 30 seconds output at a time in order to prevent the temperature of the torch becoming too high and thus protecting the LED. The high output is a constant setting of 250 lumens with a run-time of 5 hours, and mid, low and red outputs are also available.
Red light is useful for night reading, animal spotting, and preserving night vision, and the flashing red light is good for attracting attention, making it useful for in the car or on camping trips. A separate red LED sits in the middle of the white LEDs and can be directly accessed so that all-important night vision is not disturbed.
