why mainly green tho?
nothing wrong with green, but the lazers in space (ibiza) are multi coloured, and the best ive seen
tho all you need in a club is a lazer, uv and strobes, knob the rest off

Agreed lol.
Why green... simple.... Its cheap (relatively) ...LOL
I have 5 lasers ranging from 150 milliwatts upto 8 watts .
Just the lasers alone cost around £15000 (some second hand)
This doesnt include the scanners, computers or cooling equipment.
The software is all my own work so thats saved around £2000.
To acheive multicolours you need an expensive multi diode array laser source and then it has to be big enough for the venue.
Just this component alone as a 4 watt power output would be around £12k+
