Soraa releases second-generation high-output LED-based MR16 lamps

April 17, 2013
Date Announced: 17 Apr 2013 Fremont, Calif. – April 17, 2013 – Removing barriers to the widespread adoption of LED lighting, Soraa announced today its new perfect spectrum SORAA VIVID 2 and PREMIUM 2 LED MR16 lamp lines—the first ultra-efficient replacements for 65-watt and 75-watt halogen lamps, available for both 12V and line voltages. A technological breakthrough made possible by Soraa’s recently announced world-record performance gallium-nitride on gallium-nitride (GaN on GaN™) LEDs, the new SORAA LED MR16 lamps deliver the industry’s highest light output, while rendering vivid colors, richer reds and whiter whites, transforming ordinary lighting in any space into extraordinarily vibrant, brilliant and energy efficient lighting. “The SORAA VIVID 2 and PREMIUM 2 lamp lines represent a tipping point in the widespread adoption of LED MR16 lamps—we now have 65-watt to 75-watt equivalent lamps that produce full visible spectrum light and consume 80% to 85% less energy,” said Soraa CEO Eric Kim. “And what’s amazing is that we have just scratched the surface in terms of performance gains from our GaN on GaN LED technology. Look out halogens—your days are numbered.” Most LED lamps available today are based on LEDs made by depositing GaN on foreign substrates like sapphire, silicon carbide or silicon. Consequently, these LEDs have high crystal defect densities that limit the amount of current densities they can handle, thereby limiting the amount of light they emit per unit area. These high defect densities also constrain the LEDs to much lower temperatures in order to operate reliably. Both these limitations are amplified when these LEDs are used in a small form factor like an MR16 lamp, which is frequently installed in constrained or enclosed fixtures, and is used in applications that require very high light output. The lamps that use these LEDs have to make compensating design choices like using multiple LED light sources to generate the required amount of light, and active cooling mechanisms to keep the LEDs within their operating temperature range. In contrast, the SORAA VIVID 2 and PREMIUM 2 lamps’ GaN on GaN LED technology leverages the 1000x lower crystal defect density advantage of the native substrate, thus emitting substantially more light and allowing reliable operation at much higher temperatures. This enables a very simple and robust MR16 lamp design that uses a single LED light source and a simple heatsink, while producing 65W to 75W halogen equivalent light output and operating reliably at lamp temperatures of up to 120°C, a requirement for use in the most constrained fixtures.“I believe the SORAA VIVID 2 and PREMIUM 2 lamp lines will have a profound effect on lighting design—smaller form factor, high output LED MR16 lamps will now replace larger lamp types like PARs,” added Kim.The SORAA VIVID 2 LED MR16 lamp has a CRI of 95 and R9 of 95 and is available in a complete suite of beam angles, color temperatures and lumen outputs; and the SORAA PREMIUM 2 LED MR16 lamp has a CRI of 80 and is available in multiple beam angles and color temperatures. Both MR16 lamps will soon be available for line voltage fixtures. The 100V E11 lamp will be available in May 2013 through Soraa’s Japanese distribution partner Ushio. The 120V GU10 lamp for the U.S. market will be available in July 2013, followed by the 230V GU10 lamp for international markets in September 2013. The 120V E26 lamp for PAR lamp fixtures will be available in the 4th quarter of 2014.Experience the SORAA VIVID 2 and PREMIUM 2 LED MR16 lamps at Soraa’s booth (#4047) at LIGHTFAIR INTERNATIONAL 2013 in Philadelphia, PA on April 23-25th.
