The price of the product is around 1,700 yuan. As for installation costs, it depends on how many sets you have. Labor costs are calculated on a daily basis. For an 8 meter solar street light, you need to rent a crane. The crane is calculated on a daily basis. In terms of cost, if the quantity is relatively small, on average a set of several lamps will cost more. The normal installation cost is about 300 yuan per lamp, which is equivalent to approx. 2,000 yuan, excluding tax and freight. I hope this helps you. Smel Street Lights has the answer for you.
Edison wanted to invent the electric lamp. He has used over 6,000 materials and tested over 7,000 times. He did not give up after repeated failures and finally developed the bamboo silk electric lamp.
Everyone knows that the person who invented electric light was Edison. Who knows how much effort he put in?In the early 19th century, people used oil lamps, candles, etc. for light, but fires would occur if they weren't careful. In order to free humanity from the constraints of night, Edison was determined to manufacture electric lamps to bring light to humanity.
Edison invented electric light and conducted more than 1,500 experiments, but failed to find a suitable material for the electric light filament. After working tirelessly on 1,600 experiments with heat-resistant materials and more than 600 types of plant fibers, he created the first carbon filament light bulb, which could burn for 45 hours straight. Later, he continued to improve the production method based on this, and finally invented a bamboo filament bulb that could burn for 1,200 hours. It took 30 years.
