Red is expencive that is why, so more overal power gets people excited and it doesn,t cost allot more. But power isn,t everything, the lower the divergence the higher the brightness so a projector with damn low divergence will get you more WOW and better graphics. People are obcessed with power these days since 90% are just beamwavers in a club. In the gas era you had superthight beams that looked like a real laser. Want to do things right then buy a quality low mrd projector with tec cooled modules. Ok you need to invest more but you will also have more satisfaction and you can offer your client an awesome graphic show aswell. He will remember that when he is needs a second show a month later so he hires you again instead of someone else.
