FAQ

Why Do Multiple Groups of Outdoor Landscape Lights Flash Out of Sync?

Two typical scenarios exist. For wired lamps, misconnected signal wires or excessive voltage drop during signal transmission cause desync. For wireless lamps, conflicting group channels or incomplete device pairing lead to unsynchronized flashing. Double-check positive and negative signal wiring, shorten signal transmission cables, and re-group wireless channels to realize synchronous light switching.

What Basic Certification Documents Are Required for Outdoor Lighting Products Exported Overseas?

General basic qualifications include product safety certificates, IP protection test reports and light source energy efficiency test reports. CE and ROHS documents are additionally required for European and American regions, while Southeast Asian markets mostly demand local voltage adaptation test certificates. Sort all test reports and nameplate parameter files before shipment to support customs inspection for overseas buyers.

How to Prevent Fading and Paint Peeling of Outdoor Lamp Housings Under Long-term Sun Exposure?

Select lamps with outdoor weather-resistant plastic spraying coating mixed with anti-UV materials. Avoid installation locations with all-day unobstructed sunlight. Regularly wipe dust and oil stains on housings with neutral clean water. Slightly faded lamps can be repainted with matching outdoor protective paint to slow aging damage.

How to Troubleshoot Failed Remote Control of Outdoor Lighting Intelligent Systems?

Step one, confirm stable power supply without power cuts or voltage fluctuations. Step two, check wireless signal distance between gateways and lamps, as excessive obstacles weaken transmission. Step three, restart the system gateway and re-pair devices. If wiring is intact yet control fails, contact manufacturers to inspect the hardware of control modules.

What Causes Uneven Light Spots on Walls After Installing Outdoor Wall & Pillar Lamps?

Three causes include offset light lenses leading to unbalanced beam angles, installation height and wall distance inconsistent with design parameters, and dust accumulated on housing reflective layers disrupting light refraction. Adjust lens positions, install lamps per product specifications, and regularly wipe internal reflective components to achieve even wall illumination.

How to Solve Short Battery Life of Solar LED Garden Lights on Cloudy Days With Insufficient Sunlight?

First clean dust covering solar panels to secure full daytime light absorption. Versions with large-capacity storage batteries can be chosen to boost energy storage limits. Install the lamps away from buildings and trees that block sunlight. Replace aging lithium batteries when capacity drops to restore standard nighttime lighting duration on cloudy days.

Which Components Affect the Luminous Attenuation Speed of LED Street Lights?

The core related components are light source chips, heat dissipation structures and driving power supplies. Low-quality chips accelerate luminous decay; insufficiently thick heat dissipation housings or blocked heat channels create high temperatures that age light sources rapidly; unstable current output from constant-current drivers causes long-term overload and shortens service life. Regular dust removal on heat sinks slows brightness loss.

How to Fix Partial Dark Sections of Christmas Festival Light Strings After Storage?

Cut off power first and check whether lamp bead solder joints are oxidized or wires break at bending points. Then inspect plug metal contacts for damp rust. Wipe off surface moisture before storage, arrange light strings without sharp bends, and store in dry ventilated space. Replace damaged single beads with matching specifications to restore full lighting if individual beads fail.

Can Light Art Installations Operate Stably Under Sub-zero Temperatures?

Standard light art installations work steadily between -10℃ and 45℃. Custom low-temperature drivers and cold-resistant wires are required for frigid regions. Ordinary units will face slow driver startup and cracked rigid wires in prolonged sub-zero conditions. Custom versions adopt anti-freeze silicone rubber parts to expand the applicable temperature range for outdoor winter exhibitions.

Why Do LED Landscape Lights Tend to Take In Water After Long-term Outdoor Use?

There are three main causes. First, sealing rings develop gaps after aging under long-term sunlight exposure. Second, there are excessive assembly gaps between lamp housing joints. Third, wiring ports lack proper waterproof sealing. Regularly check the integrity of rubber rings, select lamps with IP65 or higher protection rating, and wrap wiring joints with waterproof glue during installation to effectively prevent water ingress.
