This is the tool preferred by astronomers at the Palomar Observatory that combines the unmatched brightness of a green laser pointer with a high-intensity flashlight.

The 532nm green laser pointer is 20x brighter than lesser red laser pointers and provides an unmistakable beam of light that appears to reach the stars--ideal for identifying distant objects, whether a constellation or a mountain summit.

The device also has three white LEDs for bright, direct light, and a red LED for ambient light capable of three levels of brightness, so you won't disturb fellow star gazers or a driver while you consult a map.
