Designed to replace a 100-watt halogen PAR38, the 24-watt Osram Sylvania PAR38 LED prototype lasts ten times longer (see Table), with a rated life of 25,000 hours. The LED lamp has a color temperature of 3,000K and a color rendering index (CRI) of 92.
The company says that the development sets a new lighting-industry record for PAR38 lamps of any type, including LED, HID and halogen technologies. Applications for PAR38 lamps include down lighting and spot lighting in residential and commercial spaces.
The new 24-watt PAR38 LED lamp prototype was developed by Osram Sylvania’s SSL advanced engineering team in Massachusetts. Led by Shawn Zhang, director of advanced engineering, the team is developing future generations of LED lamps 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 Zhang. “This allows the end users to utilize superior quality light at lower ownership cost for a longer time.”
