Which laser for which venue? This mainly depends on the desired application of the laser system: beam show, aerial effects graphics projections indoor outdoor, etc. Power and scanners (see „3. Scan Speed“) are decisive factors. For mobile DJs, home use and private parties, small bars etc., show laser systems with a total output power of up to 500mW are well suitable in most cases. Lasers in a power range of ~500mW to ~1,500mW are good for small clubs and discos, ~1,500mW to ~5,000mW suit large nightclubs, discos and mid-sized events. Lasers with 5,000mW and up are used at large in- and outdoor events, festivals, concerts etc.
