• Provide high visibility with superior brightness and uniform distribution
• Reduce maintenance and operational costs

High-Pressure Sodium (HPS) Street Lights

• Emit a yellow-orange glow with moderate energy efficiency
• Low color rendering index (CRI), making objects harder to distinguish
• Commonly used on highways and industrial roads

Metal Halide Street Lights

• Provide bright white light with better color accuracy than HPS lights
• Shorter lifespan and higher power consumption compared to LEDs
• Often used in urban streets and commercial districts

Fluorescent Street Lights

• Lower efficiency compared to LED or HPS lights
• Used in older residential areas or pedestrian pathways
• Phased out in many regions due to energy concerns

Solar Street Lights

• Use solar panels and rechargeable batteries for operation
• Reduce electricity costs and carbon footprint
• Ideal for remote areas without electrical infrastructure

Each type serves a specific purpose, and selecting the right one depends on factors like energy efficiency, brightness, and application.

LED Street Light Specifications and Benefits

LED street lights are quickly becoming the preferred lighting solution for urban roads, highways, and residential areas due to their superior efficiency, longevity, and environmental benefits.

Specifications of LED Street Lights

LED street lights are known for their advanced technology and efficient performance. Here are the key specifications you should consider when choosing LED street lights:

• Power Consumption: LED street lights typically range from 30W to 400W, depending on the lighting requirements of the area. They can provide the same brightness as traditional lights with significantly less power consumption.

• Lumen Output: Depending on the power rating, LED street lights can produce from 3,000 lumens to over 50,000 lumens. This ensures bright and even illumination across large areas.

• Luminous Efficiency: LED lights are highly efficient, providing up to 160 lumens per watt (lm/W). This means that for every watt of electricity consumed, the light output is significantly higher compared to traditional street lights like HPS or metal halide lamps.

• Color Temperature (CCT): LED street lights are available in a range of color temperatures, typically between 3,000K (warm white) and 6,500K (cool white). The most common color temperature for street lights is between 4,000K and 5,000K, offering a natural daylight-like illumination.

• Color Rendering Index (CRI): The CRI of LED street lights is usually higher than traditional street lighting, providing a more accurate color appearance. A CRI of 80 or higher is common, ensuring that objects are illuminated in a natural and clear manner.

• Lifespan: One of the most notable benefits of LED street lights is their long lifespan. High-quality LED street lights can last up to 50,000 hours, significantly reducing the frequency of maintenance and replacement.

• Ingress Protection (IP Rating): Most LED street lights are rated IP65 or higher, meaning they are fully protected against dust and water. This makes them ideal for outdoor environments where weather resistance is crucial.

• Voltage and Power Factor: LED street lights typically operate at 100-240V AC with a power factor of over 0.9, ensuring energy efficiency and compatibility with most electrical grids.

• Dimmability and Control Options: Many LED street lights offer dimming capabilities and can be controlled remotely via systems such as DALI or 0-10V dimming. This allows for better energy management and adaptive lighting based on traffic or time of day.

Benefits of LED Street Lights

Switching to LED street lights provides several key benefits for both the environment and cost-efficiency. Here are the primary advantages:

1. Energy Efficiency
