Q: How do LED fixtures impact light pollution?

Two factors have an impact to sky glow or light pollution , which are up-light and the lumen output (light level) of the fixture. To address the up light, the majority of the new LEDs are “cobra-head” fixtures and they have received the best ranking – a “zero” – when it comes to the amount of up-light they produce. ZGSM’s fixtures are “ Dark Sky ” friendly with zero up-light, which means less light pollution and/or sky glow as the light is directed downward. To address the lumen output, LEDs typically require approximately 47-58 per cent of the lumen output of the HPS light to achieve the same light levels on the pavement. This is due to the efficiency of the light source being able to direct the light where it needs to be versus the HPS light having a lot of wasted light and lack of control. By eliminating the up light and reducing the lumen output of the light source, the LED significantly reduces light pollution.

Question 1

What are the benefits of converting to LED technology?

Accepted Answer

More even and efficient distribution of light which is controlled and focused downward reducing light trespass and sky glow reduced energy consumption resulting in energy savings and reduced greenhouse gas emissions; and reduced outages and longer light life spans resulting in reduced maintenance costs.

Question 2

Why are municipalities switching to LEDs?

Accepted Answer

Municipalities around the world are switching to LED lights to save both money and energy. LED lights have approximately 50 per cent lower energy consumption compared to their HPS luminaire predecessors. HPS lights, most installed in the mid-1980s, are at the end of their useful lives and need replacement.

LEDs will provide better service reliability and lower maintenance costs. The new LEDs have a longer lifespan - about four times that of the bulbs we currently use. This translates into ongoing savings in maintenance costs as result of the extended maintenance cycle for bulb replacement. Less maintenance also means fewer service vehicle trips for repairs and as a result, reduced carbon emissions.

Question 4

Led Street Light 50 Watt Price

Accepted Answer

When it comes to LED lights street prices, the cost of installing a street light depends on the type of lighting and electricity. For example, if you install a 150W LED equivalent street light, you will need to spend at least $100 on the street light. The final cost per street light is between $3,500 and $8,000, depending on the style. If the project is a highway or bridge, the total cost of street lighting will increase by more than 20%.
