Direct answerProfessional stage lighting quality control runs in three stages: 100% incoming component inspection, a 24-hour aging test on every unit, and optical axis calibration before shipping.
The Three QC Stages
Stage 1 - Incoming inspection
All components including Nichia diodes, Osram LEDs, galvanometers and power supplies are individually tested, and rejects are quarantined before production.
Stage 2 - 24-hour aging test
Every unit runs continuously under load to test thermal stability, color consistency and electronic reliability, catching early-life failures before shipping.
Stage 3 - Optical axis calibration
Alignment to 0.01mm precision with galvanometer calibration for beam positioning and RGB color restoration verification.
Additional Quality Measures
- IP54 and IP65 waterproof potting with salt spray testing
- High-low temperature testing for extreme climate performance
- Third-party certifications including CE, RoHS, FCC and FDA
- Full traceability with no OEM outsourcing
This layered process keeps decay rates low and stability high in demanding live event environments.
