I'm considering to invest in a couple of LED PAR cans. They have to be cheap, however the light output also have to be a good quality. I was looking the thomann website and they look cheap enough, but i dont know how the light output is.
Thomann's selection of LED PARcans
Also how is the beam? i know that for some cheap LED PAR cans the light beam/shape is different according to which LED's is turned on. me don't like

Do you guys have any suggestions? how about the STAIRVILLE LED PAR 64 10 MM BLACK RGB?
OBS: I want to use the par cans for:
* giving some color on stage
* light up trees
* uplight next to a wall
