Start to look into LED lighting and quickly it becomes obvious that one type of LED will not suit all situations. After a while, you get sophisticated enough to take colour-rendering index (CRI) and colour temperature into account, and even then you are only about halfway down the check list. A little colour science There is no scientific definition of white light because, like beauty, white is in the eye of the beholder. However, everybody agrees that daylight is white, or at least a type of white, and daylight comes from the sun - a ball of gas with a surface temp...

Research has found LEDs are comparable not only in brightness to the old incandescents, but much more efficient than even compact fluorescent lights. LEDs are also built to last 15 years, compared to five years for CFLs and one for incandescents. "The LEDs are costly now, but the price is dropping very rapidly. So we have a very bright and cool and thrifty future," Chu says. Supporters say saving $10 to $11 a year in energy costs more than makes up for the initial outlay. Analysts expect LEDs to drop to $20 a bulb within two years, which is about wh...

Four different vendors are providing LED, or LEDs, for the city to test on the south side of the Claude Allouez Bridge. The energy-efficient lights cut energy usage in half and last two to four times longer than the traditional metal halide lamps. City workers could begin taking down the test LEDs as early as next week as the three-month trial comes to an end. But officials are taking notice of the advantages they provide and hope to replace the entire bridge with LED technology by 2012, assistant city engineer Karen Heyrman said. The traditional light fixtures on...

Lunera is borrowing a page from California's fast-growing rooftop solar industry. On Thursday, it plans to unveil a lease-to-purchase program that lets commercial building owners retrofit their lighting for no money down. The lease is believed to be the first in the commercial lighting sector. Lunera offers a five-year lease-to-purchase agreement with fixed monthly payments. The tenant or building owner owns the lighting fixtures, which means they, not Lunera, reap the benefits of tax depreciation. Lunera sees a strong market for its lease in cities along the East and We...
