Amidst all the hubbub about tackling global warming and cultivating green energy, one
subject receives little coverage: streetlights. While an important public service,
streetlights are expensive to maintain and taken together, suck down a lot of energy. So
when a city like Los Angeles announces that it's converting 140,000 streetlights to
light emitting diodes or LEDs, and Pittsburgh states that it's considering doing the
same with 40,000 lights, it's time to take notice.
</p>
<p>
LEDs are gaining traction as a great alternative to traditional lighting because they
are relatively environmentally friendly, don't consume much electricity and have long
life spans. They last so long -- 14 years or more in some cases -- that they can be
considered "semi-permanent"
</p>
<p>
In the past, LED lights had been seen in devices like indicator lights in appliances,
calculators or in large sports scoreboards. But now, many large cities around the world
-- Los Angeles, San Francisco, Toronto and Tianjin, China, to name a few -- are now
switching to <a href="https://www.phoebuslight.com/led-street-light/">LED Street
Light</a>. Portugal is in the midst of a massive conversion program that is expected to
encompass all of its streetlights.

<strong>Advantage of LED Streetlights</strong>
</p>
<p>
Chief among the advantages of LEDs is that they have extremely long lives -- they
don't have filaments that can quickly burn out -- and they don't contain toxic
chemicals like mercury, unlike traditional high-pressure sodium lamps or mercury-vapor
lamps. An LED light can last 100,000 hours. These lights also have reduced maintenance
costs because of their long lives, and they give off less heat than other bulbs. Because
they last so long, LEDs are suitable for places where replacing light bulbs is expensive,
inconvenient or otherwise difficult.
</p>
<p>
LEDs are highly energy efficient. While compact fluorescent lamps (CFLs) recently
have been touted as the standard in green lighting, LEDs actually have double their
energy efficiency. They use 15 percent of the energy of an incandescent bulb while
generating more light per watt. LEDs produce 80 lumens per watt; traditional streetlights
can only muster 58 lumens per watt.
</p>
<p>
Because of their energy efficiency and long lifespan, LED <a
href="https://www.phoebuslight.com/led-street-light/module-street-light/">Module Street
Light</a> is advocated as a means for reducing carbon emissions. According to one
estimate, converting all American light fixtures to LEDs would halve the amount of energy
used for lighting in the country. By integrating solar panels, the lights can become
self-sufficient and even send excess energy back to the grid, with the adoption of so-
called "smart" energy grids.<br/>
</p>
<p>

</p>
<p>
<a href="https://www.phoebuslight.com/solar-street-light/">Solar Street Light</a>s
are powered by photovoltaic panels, meaning they produce clean and sustainable energy.
When choosing to rely on solar energy for public lighting projects, local authorities can
effectively reduce their energy consumption as well as their carbon footprint. By doing
so, they limit their environmental impact and play an active part in the energy
transition, in line with national and global energy policies.
</p>
<p>
But there’s more to it. Adopting solar lighting solutions helps preserve
biodiversity in areas that are the most sensitive to light pollution. Solar street
lighting systems adjust the intensity of the light over the course of the night through
the use of dynamic lighting profiles, making street <a
href="https://www.phoebuslight.com/lighting-pole/">Lighting Pole</a> more respectful of
living ecosystems – especially birds, whose migratory behaviour is strongly affected by
light pollution.
</p>
<p>
More generally, it’s important to consider the key role played by lighting in the
creation and flourishing of communities. Quality solar lighting offers citizens a better
experience of the city. It helps improve the readability of public space, thus making it
more accessible and welcoming. It acts as a driver of social cohesion, strengthening the
ties and interaction between individuals, while allowing them to carry on their social
and recreational activities throughout the evening.

<p>
Installing <a href="https://www.phoebuslight.com/solar-street-light/all-in-one-
solar-street-light/">All in One Solar Street Light</a>s provides an opportunity to extend
parks night-time opening hours or promote access to outdoor sports facilities. In
addition to encouraging people to visit public places after dark, it also improves their
safety. On rural roads or cycling paths, the presence of solar lighting solutions helps
promote better traffic flow and reduces accidents.
