When I first started out as a concert lighting designer I had a lot of traditional par cans. The were inexpensive, put out a lot of light onto the stage, and got the job done. They also produced skin-searing heat, were bulky, took up space in my trailer, and sucked up electricity and wall outlets. I also had to be careful not to overload the dimmer packs. I slowly started to try out some early LED pars. They were rather disappointing because they were not very bright and were obviously no replacement for the power of the par. But as LED technology improved so did the LED pars. They became brighter and more affordable. I tried several brands of fixtures including generic discount lights. In the end I settled with the Chauvet line of LED pars. I found them to be reliable (even when dropped), their tech support was responsive even though I rarely needed it, and the lights were easy to program. Program? Yes-that is one of the BEST features about LED par cans. No more gels. No more color limits. Every LED par can change colors on the fly or by programming a few simple scenes into a DMX controller.
