2.professional HID street light manufacturer
3.low cost compare to LED street light
Features:
1. High light efficiency and energy saving.
Best Light efficacy for 114lm/w, one 45W cosmo system can replace the common 70W HPS street lamp.Separate electronic ballast, less than half size and weight of the traditonal magnetic ballast. The optional choose for the design of the reflector and lighting fixture, with more better efficacy.Excellent ratio for the discharge tube diameter with the lenth (A. R. ), stable light output.The light source can remains 80% brightness luminous maintenance and reduce only 10% lighting efficacy after using 3 years. And the Cosmo electronic ballast can last 60000hours, only 5% working efficacy reduced in the end of the lifetime.Compare to the sodium street lamp, it can withstand at least 5% voltage fluctuation, and with stable and constant light output. But the sodium street lamp can only withstand 3% voltage fluctuation and unstable light out put.
With more distance of light distribution scale than the sodium street lamp.
Also cosmo street lamp can use thinner diameter wire and less control box than the sodium street lamp...The nature white light can create a comfortable and attractive night, and safe driving night for drivers, making the communication between people to people in the night more comfortable.Its price is 50% of the LED street lamp, and do not need to change the lighting fixture after the ending of the lifetime, good light distribution in the road, no brightness decay after consume many long time.
