In the commercial market at least, lighting emitting diodes (LEDs) are gaining momentum as an alternative to incandescent and fluorescent technologies.
Even though the current marketshare of LEDs is pretty low, Pike Research predicts that the market share for solid-state LED lighting will reach 52 percent of the commercial lighting market by 2021. That is because the market research firm believes that costs for LED products will come down by 80 percent to 90 percent during that time period.
Said Pike Research analyst Eric Bloom:
"LEDs represent perhaps the most significant breakthrough of the last 130 years in lighting technology. The production of white LEDs, which began in the late 1990s, is starting to transform the lighting industry and the transition to this new technology is likely to occur very quickly. Rapidly-evolving technologies, such as semiconductors and software, are finding their way into the lighting market, catapulting this traditional, historically slow-moving industry into a new era of high technology."
Digital Lumens' latest technology includes integrated daylight harvesting.
One recent example of what Bloom is talking about was released in mid-November by Digital Lumens, a Boston-based developer of intelligent LED lighting systems. The company's latest 18,000- and 26,000-lumen LED lighting fixtures come integrated with sensors that enable daylight harvesting features that help adjust and balance output according to specific lighting conditions. The LightRules control system built into the fixtures helps provide for individual control over fixtures to accommodate the conditions in specific rooms or locations of an installation.
Digital Lumens has said that its technology helps customers provide the same light output at only 10 percent of the energy cost of traditional fixtures. Daylight harvesting can provide up to 50 percent additional energy savings, according to the company.
