DANVERS, MA, March 10, 2011 – OSRAM SYLVANIA today announced a laboratory achievement of 1,650 lumens for a 24-watt PAR 38 LED bulb, resulting in unmatched light output, efficacy, and color rendering according to a recent test report from a CALiPER-certified testing facility. The development sets a new lighting industry record for PAR 38 bulbs of any type, including LED, HID and halogen technologies.
The new 24-watt PAR 38 LED bulb prototype was developed by OSRAM SYLVANIA’s solid state lighting (SSL) advanced engineering team in Massachusetts. Led by Dr. Shawn Zhang, the advanced engineering team is developing future generations of LED bulbs and products for commercialization into the marketplace.
“We are excited about our accomplishment of a high lumen level, high efficacy, and high color rendering without using active cooling”, said Dr. Shawn Zhang, director of advanced engineering. “This allows the end users to utilize superior quality light at lower ownership cost for a longer time”.
The 24-watt OSRAM SYLVANIA PAR 38 LED prototype is an industry breakthrough that can provide energy and maintenance savings. Designed to replace a 100-watt halogen PAR 38, the 24-watt LED prototype lasts ten times longer, with a rated life of 25,000 hours. The LED bulb has a color temperature of 3,000K and a color rendering index (CRI) of 92. Applications for PAR 38 bulbs include down lighting and spot lighting in residential and commercial spaces.
