How to choose energy-saving, sustainable LED street lights for public areas?

We have listed some crucial factors that you should consider when purchasing LED street lights.

1. LED Driver

An LED driver is an electrical device that regulates power to an LED or a string of LEDs. It is a crucial piece to an LED circuit and to operate without one will result in system failure.

The quality of the driver impacts on the service life of the luminaire.

A lot of LED manufacturers are using self-developed LED drivers instead of brands like Meanwell. Be sure to check out the quality of the drivers used.

Typically, lighting fixtures with Meanwell driver has a 5-year warranty. Those that with lower quality drivers has only 2-year warranty.

2. Design and Construction

Poor construction will hinder the performance of LED streetlights. Unlike the interior lights, outdoor LED lights are subject to natural conditions. A broken glass could allow the water into the LED chip. Poor quality waterproof gasket and rusty body could also damage the LED street lights.

Therefore, you should choose street lights with:

  • thick tempered glass to offer sufficient protection
  • power coating to protect the light from harsh weather
  • die-cast aluminum body so that it wouldn’t rust easily and has superior heat dissipation

3. Lumens and Efficacy

With plain words, lumens indicate the brightness of the LED lights. You will need to make sure the lights give enough brightness of the area where they’re installed.

Luminous efficacy is a measure of how well a light source produces visible light. It is the ratio of luminous flux to power, measured in lumens per watt in the International System of Units (SI).

Our streetlight typically has a luminous efficacy of 150lm/w. That means if the light is 150w, then it gives out 22500 lumens.

4. Color Temperature (CCT)

CCT is defined in degrees Kelvin. A warm light is around 2700K , neutral white is around 4000K, and cool white is 5000K or higher.

When choosing the color temperature, we aim to balance the different viewpoints, environmental and safety concerns.

Therefore, we recommend 3000K for most residential roads and in parks and 4000K for street lighting on main roads to maximize driver and pedestrian safety.

Smart controls is a great addiction to the street light to dim lighting off-peak.
