With the continuous advancement of technology, the types and performance of outdoor street lights have been significantly improved. Especially in terms of energy efficiency and light efficiency, modern street lights are better than ever before. So, what are the most efficient outdoor street lights on the market? What are their characteristics and applicable scenarios? This article will give you a detailed introduction to several of the most efficient types of street lights currently available, and compare their core parameters in a table form.
1. LED street lights
LED (light-emitting diode) street lights have become one of the most popular choices on the market today due to their high light efficiency, long life and low energy consumption. They can provide powerful lighting effects while saving a lot of energy.
Core features:
* Light efficiency: 100-150 lumens/watt
* Lifespan: 50,000 to 100,000 hours
* Applicable scenarios: urban roads, parking lots, communities, industrial areas

2. Solar Street Lights
Solar street lights use solar panels to convert sunlight into electrical energy, store it in batteries, and provide power for LED lights at night. This type of street light is particularly suitable for areas without power grid coverage, and is environmentally friendly and energy-saving.
Core features:
* Light efficiency: 80-120 lumens/watt
* Lifespan: 20-25 years for solar panels, 3-5 years for batteries, 50,000 hours for LED lamps
* Applicable scenarios: rural roads, remote areas, parks, and industrial parks
