Q: Can I control each of the 4 lights independently?

A: Yes. Each fixture has its own DMX address. You assign unique starting addresses (e.g., 1, 17, 33, 49 in 16-channel mode) and your DMX console or software can control color, intensity, strobe, and effects per fixture independently. In master-slave mode, one unit acts as the controller and the other three mirror its output — useful for quick setups without a console.

Q: What is the advantage of RGBW over standard RGB?

A: RGB-only fixtures create white by mixing red, green, and blue at full intensity — the result is typically a cool, slightly purple-tinted white (~7000K) that looks unnatural on skin and fabrics. RGBW adds a dedicated warm-white diode, giving you a true white channel that can be tuned from warm (3000K) to cool (6500K) without sacrificing color saturation. For wedding photography, video production, or any application where white light quality matters, RGBW is the professional standard.

Q: How loud are the cooling fans?

A: The fans are rated below 35dB at 1 meter — roughly the noise floor of a quiet office. They are inaudible in any venue with music playing, and quiet enough for theater and worship applications where ambient noise is a concern. The aluminum housing dissipates much of the heat passively, so the fans only ramp up under sustained full-white operation.

Q: Does this require a dedicated DMX controller or can I use software?

A: Both options work. Any hardware DMX console (GrandMA, Avolites, etc.) connects via standard 3-pin XLR. For software control, a USB-to-DMX interface (like ENTTEC DMX USB Pro or similar) paired with FreeStyler, QLC+, or Lightkey on a laptop gives you full scene programming. The fixtures also support auto-run and sound-active modes with no external control at all.

Q: What is the expected LED lifespan?

A: The 8W diodes are rated for 50,000+ hours at full output — equivalent to 5.7 years of continuous 24/7 operation, or decades of typical event-production duty cycles. The active cooling and regulated power supply are designed to maintain lumen output within 10% of spec across the entire rated lifespan.

Q: Can these be used outdoors?

A: These fixtures are rated IP20 — indoor use only. For outdoor events, they should be placed under cover (stage roof, tent, truss canopy). The aluminum housing tolerates humidity and temperature swings well, but direct rain or standing water exposure will damage the internal electronics. For permanent outdoor installations, use IP65-rated fixtures.

Q: How many of these would I need for a 200-person wedding reception?

A: This quad pack alone covers a 30′×20′ area with even wash — sufficient for most wedding dance floors and head-table uplighting. For larger venues or if you need separate color zones (dance floor + dining area), a second quad pack adds full coverage. The 25° beam angle means fixtures placed 12–15 feet from the target surface produce a 5–7 foot diameter wash circle at usable intensity.

Q: What warranty and support is included?

A: Each fixture is covered by a 12-month manufacturer warranty against defects in materials and workmanship. U'King provides replacement parts and technical support for DMX configuration and troubleshooting. All fixtures carry CE, FCC, and RoHS certifications for international compliance.
