The 5050 is equipped with an internal IC, has a 12V/7mm board width, and offers a fine single-lamp single-control light and shadow effect. It is available in two types: rainproof and non-rainproof, and is compatible with both interior and exterior illuminated letters. Double-layer thickened copper sheet, resistant to bending, with reverse connection protection, anti-interference breakpoint continuation, multi-segment synchronization without color skipping.

3535 high-density LED beads with built-in IC, 12V, 6.5mm narrow board, single lamp single control with fine light and shadow, rainproof and non-rainproof versions available. Double-layer copper foil + signal anti-interference design, breakpoint continuation and stable synchronization, suitable for high-end and fine illuminated letter projects.

The 3535 lamp beads are equipped with an internal IC, 12V, 6.5mm narrow board, single lamp single control, and are available in rainproof and non-rainproof versions. The line has sufficient current carrying capacity and good heat dissipation. It can prevent reverse connection and signal interference. The damage of a single lamp does not affect the overall operation. It is suitable for various fine illuminated letters.

It adopts 5050 LED external IC, 12V, 10mm board width, 3 lights and 1 control. The rainproof model is suitable for outdoor storefronts. The double-layer thickened copper sheet is resistant to bending, equipped with reverse connection protection, strong anti-interference, no garbled characters when resuming transmission from breakpoints, and the engineering installation is stable and safe.
