Introduction to light, the configuration of the solar street lamps town

Light, top and bottom diameter should be much more appropriate? I think this problem has been plagued by many customers, while customers don't know these professional data parameters, but they are concerned about most is the price, and the size of diameter of high lamp directly decides the whole lamp price

the size of the up and down light, should have how old? I think this problem has been plagued by many customers. While customers don't understand these specialized data parameters, but they are concerned about most is the price, and will directly decide the calibre of the light, the lamps and lanterns of the overall price. Took a 27 meters high pole lamp, not light source equipment, many manufacturers offer in 25000 yuan, while other manufacturers offer more than 33000 yuan, 8000 yuan. What's the difference? Careful friends may have thought of, yes, this is caused by the size of the aperture. 27 m high lamp on the upper and lower diameter usually diameter is 260 mm, the diameter is 580 mm, weight is limited, but the specifications generally should not exceed 200 kilograms. 400 w high pressure sodium lamp, for example, the weight of the lamp is about 15 kg, the weight of the lamp panel usually is about 100 kg. Accordingly, the diameter of the light, only suitable for 6 lights. If you want to install more lights, you must increase the diameter of the opening up and down.
