The technical specifications of street lights can vary based on factors such as the type of street light, its intended application, and regional standards. However, here are some common technical specifications for traditional high-pressure sodium (HPS) and light-emitting diode (LED) street lights:

 

Type of Light Source:

HPS (High-Pressure Sodium): Common in older installations, emits a yellow-orange light.

LED (Light-Emitting Diode): Energy-efficient and increasingly popular, with options for different color temperatures.

 

Luminous Flux:

Measured in lumens (lm), this indicates the total amount of light emitted by the source.

Higher lumens generally mean a brighter light.

 

Wattage:

Indicates the power consumption of the street light.

For LED lights, lower wattages can often produce the same or higher lumens compared to traditional HPS lights.

 

Color Temperature (for LED lights):

Measured in Kelvin (K), it represents the color appearance of the light.

Warmer temperatures (e.g., 2700K) appear more yellow, while cooler temperatures (e.g., 5000K) appear more bluish-white.

 

CRI (Color Rendering Index):

A measure of a light source's ability to reveal the true colors of objects compared to an ideal light source.

Expressed as a value between 0 and 100, with higher values indicating better color rendering.

 

IP Rating (Ingress Protection):

Indicates the level of protection against dust and water.

Common IP ratings for outdoor lights are IP65 or higher.

 

Operating Voltage:

Specifies the range of electrical voltage within which the street light operates.

 

Power Factor:

Describes the efficiency of power usage in the lighting system.

A power factor close to 1 indicates efficient power utilization.

 

Mounting Options:

Specifies the types of mounts available for installation (e.g., pole-mounted, wall-mounted).

 

Material and Construction:

Indicates the materials used in the construction of the street light, including housing, lens, and other components.

 

Operating Temperature Range:

Specifies the temperature range within which the street light can operate effectively.

 

Control and Dimming Options:

Some modern street lights offer smart features, allowing for remote monitoring, control, and dimming based on conditions or time of day.

It's important to consult with local authorities and adhere to regional standards and regulations when selecting and installing street lights. Additionally, advancements in technology may lead to changes in specifications, especially with the adoption of smart lighting solutions and energy-efficient technologies.
