Whether or not you agree with the idea that LED light bulbs can save energy in residential settings because of their ridiculously high price tags, I'm a firm believer in their municipal applications. So, I read with interest that Dialight has updated its portfolio of lighting technology intended to help illuminate roadway and infrastructure signage.
The product, called StreetSense LED Roadway Sign Light, comes in two different versions. One is a 6,000-lumen, 70-watt (W) lamp that is used in multiples to light up signs larger than 14x14 feet. The other is a 4,000-lumen, 40W edition that is meant for smaller signs.
They weigh less than 20 pounds each and use approximately 30 percent less energy than previous-generation fixtures, according to Dialight's research.
The company also promises a much longer lamp life. Tests show that they maintain up to 70 percent of their lumen output after 60,000 hours, which means they don't have to be changed as often as their HID metal halide counterparts.
Said Roy Burton, Dialight Group chief executive, in the company's press release about the new fixtures: "Typical roadway sign lighting is costly to operate and a major drain on maintenance resources, not to mention the traffic headaches caused by the frequent bulb changes required of HID lighting fixtures. This new StreetSense LED fixture resolves all of those challenges, slashing operating and maintenance costs by nearly 75 percent compared to traditional 100-250W HID sources and freeing up precious manpower for other more important projects."
