There have been great strides in the development of the LED technology over the years. They have become more durable, cheaper to produce and much more versatile. Conversely, the older types of lighting, namely the incandescent lights have pretty much reached their zenith years ago and could not be perfected any further.
So, what happens when you combine the fledgling technology of solar lighting with the efficiency of the LED type of lighting? You get amazing results and revolutionary results in both conservation of energy and cutting the costs of maintenance. Take the example of solar LED parking lot lights that are cropping up all through the USA. The solar collectors store energy in the batteries which is then used to power the LEDs during the night. All without being attached to the central electricity grid. This is possible due to the clear advantages of the LEDs over the other types of lighting.
