There is a lot going on with the Moon Rigel Pro Rechargeable front light when it comes to technology - a little bit too much, possibly, for some. It features &';Intelligent Operation&';, which means it can activate itself in the dark and turn off when there is no movement, and you can alter the brightness in each mode, too. Even the battery life is decent for such a small light, although I&';m not exactly blown away by the anti-dazzling lens.
