2. Level, LED stream protection level A level 1 should not be lower than IP67; B-class products should not be lower than IP66; C-class should not be IP65.

3. Average life, the rated average life of the LED street light should not be less than 30000h.

4. Maximum temperature, LED street light rated maximum temperature Tc value should not be greater than 58 ° C.

5. Maximum heat sink temperature, the maximum heat sink temperature of each LED tube in the lamp should not be greater than 65 ° C.

6. Main light parameters

7. Anti-disturbance, surge inhibition performance (anti-lightning) voltage protection level should not be less than 2kV (line-line) and 4KV (line-ground).

6. Side of light distribution characteristics, part of the LED bulb in the lamps is extinguished or the light is dimming, the spot shape and the road surface illumination uniformity should not change significantly.
