1. Brightness: The brightness of the lighting is different and the price is different.

2. Anti -static capacity: Lighting with strong anti -static capabilities, long life, so the price is high. Lighting that is usually more than 700V with anti -static electricity can be used for lighting fixtures.

3. Wavelength: Lighting with the same wavelength, the same color, if the color is required, the price is high. Manufacturers without lighting springs are difficult to produce pure color products.

4. Leakage current: Lighting is a light -oriented lighting body. If there is a reverse current, it is called the light leakage, the leakage current is large, and the life span is short and the price is low.

5. Lighting angle: different lighting angles with different uses are different. The special lighting angle, the price is high. For example, the full -firing angle, the price is higher.

6. Life: The key to different quality is life, life is determined by light decay. Light failure, long life, long life, high price.

7. Lighting chip: The lighting body of the lighting is a chip, different chips, the price is very different.

8. The size of the chip: The size of the chip is represented by the side length. The quality of large chip lighting is better than that of small chips. Price is proportional to the size of the chip.

9. Collagen: The colloidity of ordinary lighting is generally epoxy resin, which is more expensive with light -resistant and fireproof lighting. High -quality outdoor lighting decoration should resist ultraviolet rays and fire prevention.
