FAQ
What is the difference between beam, spot, and wash moving heads?
Beam heads produce tight, high‑intensity shafts; spot heads add gobos and framing for pattern projection; wash heads deliver soft, wide color fields. CR‑TEC Moving Head series covers hybrid solutions combining all three effects.
How to choose IP‑rated outdoor stage lights?
For permanent outdoor installations, prioritize fixtures with IP65 or higher rating, anti‑corrosion treatment and thermal‑control features. CR‑TEC Proto / Rapto series provide IP65 protection rating.
What DMX protocols should a professional fixture support?
At minimum, DMX512/RDM is required. Large‑scale network‑based systems need Art‑Net / sACN compatibility. The full CR‑TEC product line supports DMX512/RDM.
What certifications matter for exporting stage lights to EU/US?
CE + RoHS certifications are required for the EU market; ETL/cETL certifications are needed for the US market. CR‑TEC holds CE, RoHS, ETL certifications and complies with ISO 9001:2015 quality‑management system.
