Waterproof Wall Washer Manufacturer 18 × 10W Waterproof Wall Wash Lights

Troubleshoot in 4 steps:

1. Power Supply: Confirm the input voltage matches AC 200V~240V/50~60Hz; check if the power cable is securely connected and the switch is on.

2. Cooling Period: Ensure the fixture has cooled for 20 minutes after previous use (mandatory cooling to prevent overheat damage).

3. DMX Signal: If in DMX mode, verify the controller is sending "Shutter On" (CH6: 252-255) and "Dimming" (CH7: 100-255) signals.

4. Internal Wiring: If above checks pass, contact after-sales to inspect internal connections (e.g., lamp holder, driver board) for loose or burned components.

All our lights adopt imported LED chips, with a service life of ≥ 50,000 hours under normal use (8 hours of daily use can last for 17 years). The replacement of lamp beads requires professional operation—due to the involvement of wire soldering and heat dissipation adaptation, unprofessional operation may cause short circuits or uneven light effects. You can contact the after-sales team for on-site replacement or repair-by-mail services.

Resolve overheating issues:

1. Environment Check: Ensure the operating temperature ≤60℃; move the fixture away from heat sources (e.g., stage heaters) and ensure 50cm clearance around the fan grille.

2. Fan Maintenance: Clean the fan and fan grille with compressed air (remove dust buildup); check if the fan runs when the fixture is powered on (replace fan if silent).

3. Protection Threshold: Enter "Settings → Temperature Protection" to adjust the threshold (default 60℃, max 80℃) if the environment requires higher operating temperatures.

Address the issue as follows:

1. Mechanical Check: Open the fixture (after power-off) to inspect if the X/Y axis belts are loose or broken; re-tighten or replace belts if needed.

2. Optical Coupling Calibration: Enter "Settings → Motor Calibration → X/Y Axis" to adjust the offset (-128~+127) or enable "Optical Coupling" (auto-corrects step loss).

3. Reset & Restart: Press "Menu → Reset → XY Reset" to reposition the axes; if no response, check the X/Y axis photoelectric switches (replace if "X/Y Hall Error" appears in the error menu).

Resolve with these checks:

1. DMX Address & Channels: Ensure the fixture’s starting address is correct (e.g., 34CH fixture 1: A001, fixture 2: A035) and the controller’s channel count ≥ total fixture channels.

2. Signal Wiring: Use shielded twisted-pair DMX cables (≤150m); install a 120Ω terminal resistor between pins 2-3 of the last fixture’s XLR connector.

3. Signal Amplification: For cable lengths >150m, add a DMX signal amplifier to avoid signal loss; separate DMX cables from high-voltage power cables (≥1m apart) to prevent interference.
