1. Look at brightness. Generally, the brightness of LED lamp beads is different, and its price is different. Generally, the larger the brightness, the more expensive the price. The greater the brightness, the better the decorative performance. When buying, the LED lamp beads can be lit for a while to see how the brightness is.

2. Test anti -static ability. LEDs with strong anti -static capabilities are long, so the price is high. Usually, the anti -static electricity is more than 700V LED to be a real LED. It is not easy to burn out due to unstable voltage during use.

3. Light wavelength. It depends on whether the consistency of the light wavelength of the LED lamp beads meets the standards. The luminous color of the LED lamp beads with the same wavelength is consistent. If the color is consistent, the price is high. Therefore See if the light wavelength is the same.

4. Safety performance. The level of safety performance directly determines the long -term service life of LED lamp beads. The colloid of ordinary LED lamp beads is generally epoxy resin, and the market also has LED lamp beads with anti -ultraviolet and fireproof agent. The price is naturally more expensive. However, the safety performance of this LED lamp bead is generally high when used, especially when it is installed outdoors, you can use it with confidence.
