I am very new to this forum as well as my experience with lasers. I recently went to a concert and saw someone with 3 lasers (red, green, and UV he was calling it). The beams on these lasers were extremely bright, on the green and red you could see the beam through the air. He also had caps on the laser and was able to light up the ENTIRE ceiling of a circus sized tent they had at one of the side shows. I asked the guy about them and he told me he was selling all 3 brand new in the package for $150. I did a quick internet search and came up with what I am pretty sure he had.
I am looking to get a laser that has a very intense beam as well as the ability to light up a ceiling like that. Are these good lasers? or is there something that has an advantage over the ones in the link? I am looking to spend not much more than 30 bucks for each one. I would like to start with green and red, than possibly get a uv or maybe different colors. Once again please point me in the right direction of a laser that you think fits what I am looking for. Thanks.
