Please remind how we performed Laser light show in the past: For a show, we had to prepare 1 to 3 laser beam guns with water cooler and high voltage supply. But now, time is changed and laser system is changed since 2000. We became to be free from such difficulties, saving money and time and effort by our Laser projectors. By our Diode Laser projectors, you can more spectacular show whit more projectors. For a dazzling show, more than 8 projectors are needed. Please keep your mind our price is very reasonable.
