Toshiba Buys LED Maker GreenStar
In February 2012, Toshiba International Corporation entered into an agreement with San Antonio, Texas-based GreenStar to produce the LED luminaires and has since been marketing, selling and distributing the GreenStar products within the United States, Canada and the Caribbean. Toshiba Lighting & Technology Corporation is coordinating with Toshiba International Corporation to manage the relationship with GreenStar and will continue selling its products in North America.
GreenStar’s product designs include photometric controls for light distribution and light uniformity. Additionally, GreenStar’s roadway product includes a built-in photocell that has a rated life that exceeds the life of a conventional NEMA twist lock photocell by as much as three times, according to the company.
The GreenStar LEDs are direct replacements for conventional HID lighting, such as high-pressure sodium or metal halide.
LEDs are gaining steam in the marketplace and were a hot topic of discussion at the recent LightFair conference in Philadelphia.
According to Charlie Szoradi, CEO of Independence LED, there are three main factors to consider when thinking of an LED retrofit:
- run time,
- inefficiency of existing lights,
- cost of electricity.
Retrofitting streetlights to LEDs is another trend. New York City, for example, is replacing all its streetlights, about 300,000 bulbs, with LEDs and expects to complete the project by 2019, resulting in a 35 percent decrease in energy consumption for streetlights.
