Though LEDs may not generate heat to the extent of other light sources, they are very sensitive to heat, so equally, just as a well-designed light bulb might extend an LED's longevity, might a poorly designed one compromise it? "I think that many companies fall out of the Energy Star qualification process because of that, because they don't have sufficient thermal management which is one of our big advantages," Rosenfield said, alluding to the LQD liquid cooling system employed in Switch's bulbs.
"Also companies fall out because they don't have the full light distribution required. For example, with an 'A lamp,' you have to have, to get the full Energy Star standard, 170 degrees of radial flux or light distribution all around the product at generally the same intensity all the way around," he added.
To pass the Energy Star benchmarks, Rosenfield concludes, products must perform robustly as well as demonstrate long life. He also explained that the EPA will pick up Energy Star-certified products in the market place to ensure that their performance matches what was certified – that the products are what they're being sold as, effectively.
