-Different types of laser pointer can show different colors of light, and the apparent brightness of a spot from a laser beam depends not only on the optical power of the laser and the reflectivity of the surface, but also on the chromatic response of the human eye. -The laser pointer can be used to highlight something of interest by projecting a small bright spot of colored light onto it. It can be used in different areas which include educational and business presentations, architecture, astronomy, camp and adventure, and entertainment etc. -100 to 300 ft. during the day and up to 1000 ft. at night. Up to 50 times more powerful than most other laser pointers. -Just Remove Disco Light Effect Cap From Pen To Get Straight Pointer Light For Presentation. -Powered by 2 x AAA batteries.
