Frequently Asked Questions
What makes WS2811 COB LED strips different from regular COB?
The WS2811 IC allows the strip to be "addressable," meaning you can control the color and movement of light segments individually, creating dynamic "dream color" effects like chasing and flowing, which standard COB strips cannot do.
Can I cut the strip to a specific length?
Yes, the strip is cuttable every 50mm. This allows you to tailor the length precisely to your project requirements.
Do I need a special controller for this LED strip?
Yes, because it is an addressable RGBIC strip, you will need a WS2811-compatible pixel controller (Remote, Bluetooth, or WiFi) to manage the color effects.
Is the strip suitable for outdoor use?
We offer various waterproof ratings ranging from IP20 (indoor) to IP68 (fully waterproof). Please select the appropriate IP rating based on your installation environment.
What is the advantage of 720 LEDs/M density?
The high density ensures a completely seamless light output with no visible "dots" or dark spots, even when installed in shallow profiles or used for direct view lighting.
How long is the product warranty?
We offer a warranty period of 2 to 5 years depending on the specific model and application. During this time, we provide repair or replacement for any quality-related issues.
