Material: The light-emitting diode is made of PET + copper, which combines the heat endurance of PET and the excellent conductivity of copper, improving the overall performance and durability of the LED light-emitting diode. Flexible Scope of Application: Suitable for various occasions such as indicator lights and lights to meet the needs of different electronic products. Narrow Beam Angle: With a beam angle of 30°, it provides accuracy light pointing to ensure clear and visible indications. Convenient Installation: The lead length is about 20 cm/7.9 inches, the red wire is connected to the positive pole, and the black wire is connected to the negative pole. The wiring is simple and easy to install. Wide Application: The diameter of the LED lamp bead is only about 3mm/0.1in, which is suitable for remote control cars, boats, industry, cameras, toys and other fields.
