Osram Sylvania and Lowe`s reveal light bulbs for Iris
The ULTRA iQ LED bulb is claimed to be the first with remote dimming capabilities designed for Lowe’s Iris home management system
North American lighting designer Osram Sylvania has united with Lowe’s to introduce SYLVANIA ULTRA iQ, as the first LED bulb designed to work with the Lowe’s Iris home management system.
SYLVANIA ULTRA iQ LED bulbs are flood lights that work with Iris to eliminate the need for conventional wall dimmers by allowing consumers to control lighting and set lighting scenes wirelessly from anywhere in the world with access to the internet.
Now available on
Lowes.com and in most Lowe’s locations, SYLVANIA ULTRA iQ bulbs offer superior dimming quality and wireless dimming controls that are compatible with smartphones, tablets, and the Iris system. SYLVANIA ULTRA iQ bulbs are easy to use and are up to 80 percent more efficient than traditional lighting.
“With ULTRA iQ and Iris, consumers can now remotely control their lighting through smart devices while saving on electricity costs,” says Ellen Sizemore, product portfolio manager LED lamps, Osram Sylvania. “These light bulbs are long lasting, energy saving options designed to easily integrate with the smart homes of today.”
SYLVANIA ULTRA iQ bulbs have a rated bulb life of 35,000 hours, which reduces maintenance and bulb replacement costs. In a typical home, with lights in use three hours a day, that 35,000 hours translates to nearly 32 years.
Using only 11 W, SYLVANIA ULTRA iQ LED bulbs are replacements for 65 W incandescent bulbs and feature integrated-wireless dimming control within the bulb. These ULTRA iQ bulbs are designed for optimum use in kitchens, family rooms, bedrooms, hallways and hard to reach areas in the home. The products contain no mercury, lead or other hazardous materials.
Iris, Lowe’s exclusive smart home solution, allows consumers to monitor and control virtually everything in the home anytime, anywhere. Iris offers consumers the ability to lock or unlock doors, change thermostats, turn on and off lights, set security alarms, monitor smoke and water detectors, and more - all from a single app controlled from a smartphone, tablet, or computer.
Iris is easy to set up; do-it-yourself installation typically
takes approximately one hour. Retail prices start at $179, with free basic service.
Lowe’s Companies, Inc. serves approximately fifteen million customers a week at more than 1,825 home improvement and hardware stores in the United States, Canada and Mexico.
Momentive extends manufacturing capacity of TaC
The expansion will help to enable next generation SiC epi tools and provide improved dimensional control for current GaN tools
Momentive Performance Materials Quartz Inc. (MPM) has increased and expanded its manufacturing capacity of tantalum carbide coatings (TaC) in response to the larger demand for SiC power devices and increased need for improved dimensional control for GaN LEDs.
With the expansion, MPM has the capability to produce up to 750 mm diameter parts, versus the 500 mm previous limitation. The diameter increase can help enable next generation SiC epi tools and can provide improved dimensional control for the current GaN tools now using alternate protective coatings.
MPM’s TaC is manufactured using a proprietary coating process, which yields excellent resistance to hot hydrogen during epitaxial processes. SiC coatings can start to decompose at 1200 to 1400oC, whereas TaC generally is stable to over 2000oC.
Additionally, the coatings can provide exceptional dimensional control and, therefore, a uniform and conformal coating, even on wafer pockets and complex shapes. TaC coatings are used in MOCVD tools for the production of GaN and SiC devices.
Seoul Semi, LEDLab and UC Davis unite in luminaire design competition
