Solar Street LightAlmost 17 years ago a community in the Caribbean purchased solar street lighting systems for areas around the neighborhood. Now they are purchasing additional lights to expand their current installation. Technology has changed a lot since the first light was installed. Here’s a comparison of the technology used then and now.

Solar LED Street Light Fixtures

The old style lights use compact fluorescent lamps while the new design uses LED fixtures. The cost of the new fixtures is a little higher than the old style Cobrahead fixtures; however, the overall savings from using LEDs will pay for the new fixture design quickly. LEDs use about 1/3rd the amount of power to provide the same lighting as CFL lamps and last over five times longer.

With higher efficiency lighting available through LED technology allows for lower power consumption. The old solar lights required a larger power system to light the streets from dusk to dawn. The lower power system also does not require as strong of a pole for hurricane resistance lowering overall system cost by as much as 10%.

Finally the new systems’ mounting system is a lot different. The new T-Top style mounting uses less resources, is easier to install, and provides less wind resistance than before which is great for hurricane prone areas. The fixture mounting is now a curved, tapered, upsweep bracket that is more architecturally pleasant compared to the old style straight pipe.

It is always nice to see how technology advances and changes over the years. After 17 years of service the new systems will fit in great providing the community additional security through LED street lights. What other lighting technology changes has happened in the last decade and a half?
