For the procurement of lampshade and lamp bead industry, it will often face the purchase of various brands. What are the tips for choosing such products? Let's take a look with High Lumen Street Light Housing suppliers.
1. Different brightness and different prices. The lampshade and lamp beads used in the lamps and lanterns should meet the laser class Ⅰ standard.
2. Antistatic Capability The lampshade with strong antistatic capability has a long life and is therefore expensive.
3. The lampshade and lamp beads with the same wavelength have the same color. If the color is the same, the price is high.
4. Leakage current lampshade lamp beads are unidirectional conductive luminous body. If there is reverse current, it is called leakage. Lampshade lamp beads with large leakage current have short life and low price.
5. The luminous angles of different lampshade and lamp beads are different. Special light angle, the price is higher. Such as full diffusion angle, the price is higher.
6. Lifetime is determined by light attenuation. Low light decay, long life, long life and high price.
7. Wafer size The size of the wafer is expressed by the side length. The quality of the large wafer is better than that of the small wafer. The price is proportional to the chip size.
