When sourcing a laser show system, the most critical technical factor is the Laser Power (measured in Watts or mW) and the Scanner Speed (measured in Kpps - Kilo-points per second). For indoor venues, 1W to 5W systems are usually sufficient, while outdoor landmarks or large stadiums require 10W to 50W+. Ensure the scanner speed is at least 30kpps @ 8° to prevent flickering in complex graphics. Additionally, look for RGB color balance (e.g., 1:1:2 ratio for Red, Green, and Blue) to ensure a pure white beam and vibrant secondary colors.
