What Makes Soraa Lamps Different? Why is Overall Beam Pattern Important? There are three components of the beam angle in directional lamps: center beam candle power (CBCP), field, and spill. CBCP and field are what lighting designers consider as usable lumens. Lumens falling outside this area are called “spill.” Designers try to eliminate spill by using baffles, lenses and other accessories. Many LED directional lamps only concentrate on CBCP, and produce minimal light in the field, so they miss a key component of good lighting design. Others have a significant amount of spill, so even if they have lumens in this area, these lumens are not considered usable. Most lamps have irregular beam patterns with many artifacts and poor centerto-edge color consistency. So when choosing an LED MR16 lamp, it’s important to evaluate all the features of usable light, including CBCP, field, beam shape, and color over angle. Only Soraa’s LED MR16 lamp delivers a perfect circular beam, with the right amount CBCP and field, minimal spill, soft transitions and high center-to-edge color consistency. What’s the Difference Between NEC Low Voltage Class 1 and Class 2 Systems and Why is This Distinction Important? The National Electric Code (NEC) defines and determines safety requirements for these systems. In terms of 12VAC lighting, NEC Class 2 low voltage systems are defined as systems using transformers that are 60W or less. These Class 2 systems have less stringent safety requirements than other systems. UL defines the transformer safety standards under UL1310: Class 2 Power Units. NEC Class 1 low voltage systems are over 60W in 12VAC and have more stringent safety requirements. UL defines the transformer safety standards under UL1012: Power Units Other Than Class 2. Many LED MR16 lamps state that they are only for use in Class 2 systems. Using a Class 2 lamp with a power unit other than Class 2 violates UL and creates a potential safety issue. Some LED MR16 lamp manufacturers say nothing about which UL transformers are suitable for use with their lamp, so it is unclear if they are UL tested for use with UL1012 transformers in Class 1 low voltage systems, or only rated for Class 2 applications with UL1310 transformers. Soraa’s LED MR16 lamp is the ONLY UL listed lamp that is specifically listed for use with both UL1012 and UL1310 Power Units in Class 1 and 2 low voltage systems. What Other Requirements Are Important? LED lamps legally must comply with FCC requirements, CFR 47 Part 15 and Part 18. Some LED lamps may not comply with this requirement and may be subject to FCC sanctions, including fines and recalls. Soraa’s LED MR16 lamp complies with all FCC requirements, as tested by an independent certified laboratory. Halogen beam (top) shows uneven pattern and spill. Bottom image (rendered from IES file) shows approximately 35% wasted lumens projecting from top of lamp. Beam from Soraa lamp (top) shows even pattern and minimal spill. Bottom image (rendered from IES file) shows a clean, efficient beam pattern.
The Soraa Team Founded in 2008 in Goleta, California by a team of pioneering professors from the worlds of engineering and semiconductors, Soraa is the world’s leading developer of solid-state lighting technology built on pure gallium nitride substrates, commonly referred to as GaN on GaN. Soraa’s investors include Khosla Ventures, NEA, and NGEN Partners. Professor Shuji Nakamura, founder Professor Nakamura may have single-handedly changed the technological face of the world. His discovery of p-type doping in Gallium Nitride (GaN) and development of blue, green, and white light emitting diodes (LEDs) and blue laser diodes (LDs) has enabled energy efficient, solid-state lighting used in displays, medicine, and the next generation of Blu-Ray optical storage. Now, Dr. Nakamura’s inventions are poised to replace Thomas Edison’s light bulb and save the world billions of dollars in energy costs. Dr. Steven P. DenBaars, founder Professor of Materials and Co-Director of the Solid-State Lighting Center at the University of California Santa Barbara, ranked number one in the nation by the National Research Council, Dr. Steven P. Den- Baars’ interest in growth of GaN based semiconductors and their application to Blue LEDs, lasers and high power electronic devices lead to the first US university demonstration of a Blue GaN laser diode and more than seven patents pending on GaN growth and processing. Professor Jim Speck, founder Materials Department Chair at U.C. Santa Barbara, ranked number one in the nation by the National Research Council, Professor Speck has worked extensively on the materials science of GaN and related alloys. He received the Quantum Device Award from the International Symposium on Compound Semiconductors in 2007, was named an inaugural MRS Fellow in 2008, received the JJAP Best Paper Award in 2008, became an APS Fellow in 2009, and received the IEEE Photonics Society Aron Kressel Award for his work on nonpolar and semipolar GaN-based materials and devices. Eric Kim, CEO Kim rocketed to fame in the IT world when Samsung appointed him to reinvigorate marketing in 1999. At the time, Samsung was mostly a second-tier brand known for cheap electronics. As Global CMO/ EVP New Business Development, he transformed Samsung into a premium consumer brand. Not long after, Kim moved to Intel as SVP/ GM for the Digital Home Group, delivering next-generation SoC (System-on-a-Chip) for web-enabled SmartTVs. Mike Krames, CTO With 20 years of laser diode and LED R&D experience, Mike is a former Executive VP at Philips Lumileds, where he formed and ran the Advanced Laboratories and its research on III-nitride epitaxy, LED device technology, and luminescent materials. He spearheaded many key solid-state lighting advancements, including flip-chip and thin-film flip-chip technologies, photonic crystal LEDs, ceramic phosphors, and advancing understanding of the “droop” mechanism in InGaN-GaN LEDs. A senior member of IEEE, he has published over 70 papers and has over 100 patents in the solid-state lighting field. Frank Steranka, SVP Engineering Dr. Steranka joined Soraa in June of 2010 and has been in the LED business since 1984. With Hewlett Packard’s Optoelectronics Division, he worked on the successful commercialization of a wide variety of LED products based upon the AlGaAs, AlInGaP, and InGaN materials systems. In 1999, he joined the Agilent-Philips Lumileds Lighting joint venture where he served in many roles including Executive Vice President of R&D and CTO. With a Ph.D. in Physics from the University of Illinois at Urbana-Champaign, Frank has participated in or led the release to market of over 200 LED products.. Neal Woods, SVP World Wide Operations Mr. Woods joined Soraa in July, 2011 and has held a variety of executive manufacturing engineering and manufacturing operations roles at Texas Instruments, Apple Computer, 3Com, and Cisco Systems. He most recently served as Senior Vice President of Operations for Hewlett-Packard’s Imaging & Printing Group. While at HP, he had ownership for IPG’s supply chain, which shipped both high volume and high complex products with annual revenues in excess of $25B. He received his B.S.E.E. degree from Kansas State University.
