Samples of the Philips 10-watt LED lamp were submitted in 2009 and have completed 18 months of field, lab and product testing. Performance requirements included an output in excess of 900 lm, and a useful lifetime of more than 25,000 hours.
Philips also says that the lamp “could arrive in stores as soon as early 2012.”
A more in-depth version of this story will be posted on the LEDs Magazine website very shortly.
![FIG. 1. The timeline of light sources relied upon by humans has evolved from one focused on the source of illumination for visual acuity alone to one that applies advanced research to evoke or inhibit certain responses from the non-visual system. The research will deliver new information to the solid-state lighting (SSL) industry for producing metrics that enable standards and best practices development for products and lighting designs.
