LED guardrail tube purchase: When purchasing a product, ask the parameters of the product, including the number of lamp beads, the material of the circuit board, where the lamp beads are produced, the brightness, the waterproof effect, etc.; whether there are spare parts, the quality is directly determined. Project recovery. In addition, when choosing the PC shell of the guardrail tube, you can choose the translucent outer tube, which has high brightness and obvious running water effect, which solves the problem that the transparent tube has no color mixing effect and the brightness of the milky white tube is not high enough.

              Selection of LED strips: When using LED strips for projects, try to use all-copper wires. All-copper wires are more durable than copper-clad aluminum wires and aluminum wires. The lamp beads use high-brightness ones. Some manufacturers specialize in low-end products. The products are of inferior quality and are often easily damaged. The brightness of the lamp beads is very low. In some cases, the lamp beads are produced with wafers, and the lamp strips will be dimmed for three or two months after being installed.

There are many products, so I won't explain them one by one here. The general principle is: cheap products are not good products, good products are not cheap, and mid-range products are fine.
