LFI's 20th anniversary spotlighted two spectacular keynote luncheons during the Daylighting Institute and the LIGHTFAIR Institute. Ed Begley Jr. spoke on Sunday, May 3 and James Turrell on Monday, May 4. Topics addressed during each luncheon included sustainability and light as art and inspiration. Both luncheons individually attracted a packed house of attendees.
Evluma developed the new wide optic version of the 40W Clearlight as a companion to its existing narrow optic, or lambertian luminaire. Both luminaries are designed for use in 50-175W Mercury Vapor (MV), or 70-150W High Pressure Sodium (HPS) mogul base, dusk-till-dawn fixtures. With peak intensity vertical angle of 0o, the narrow optic Clearlight is recommended for areas over doorways or loading docks where more light is required directly under the fixture. The wide optic is recommended for parking lots and roadways, anywhere lighting design dictates an even wash of light, says the company.
The Clearlight contains no mercury, and is dark-sky friendly with full cut off; the highest percentage of lamp lumens falling in the 0o-60o zone for both models. With an overall projected life-time well beyond an L70 of 70,000 hours, the Clearlight requires very little maintenance compared to legacy HPS and MV, according to the company. Evluma distributors are currently taking orders for the new Clearlight 40W Wide Optic LED luminaries with stock available mid-August, 2009.
LED light engine manufacturer, today announced a five-year (or 35,000-hour, whichever comes first) warranty on their complete line of LED Universal Light Engine(TM) products. These light engines provide full plug-and-play functionality, making it simple for designers to incorporate solid-state lighting into a wide variety of existing and new luminaires. OptoElectronix Universal Light Engines include the LED, a thermal network, optics, the electronic driving system for the LEDs, and a range of control functions. The warranty is effective as of August 1, 2009.
