LED Strip Lights: China Manufacturer Sourcing
1 resources tagged with "Strip Lights"
LED strip lights are one of China's highest-volume lighting exports, sold in 12V/24V flexible reels with SMD2835 or SMD5050 chips and IP ratings from IP20 (indoor, bare) to IP68 (fully encapsulated). The two specs that decide quality are LED density (LEDs per meter) and copper weight in the flexible PCB — thin copper causes voltage drop and visible dimming toward the end of a long run. CE/RoHS is standard for EU sales, but lumen consistency reel-to-reel is the real sourcing challenge.
When sourcing LED strip, confirm the PCB copper weight (commonly 2 oz on better strips) and the exact chip (SMD2835 vs 5050) and density, because these drive brightness and voltage drop. The common pitfall is buying on price per meter and getting underfed strips that dim noticeably over a 5 m run.

FAQ
What IP rating do I need for LED strip lights?
IP20 is fine indoors and dry; IP65 silicone coating handles splashes; IP67/IP68 encapsulation is for wet or submerged use. Match the rating to the install — over-specifying adds cost and stiffness.
Why do cheap LED strips dim toward the end?
Thin copper in the flexible PCB causes voltage drop along the run, so the far end gets less power and looks dimmer. Specify heavier copper (e.g. 2 oz) and inject power at both ends for long runs.
