9. Proprietary Information Of Energy 2013 LED? Still dealing with high cost Efficacy is improving almost weekly, lm/watt continue to rise. – Physics say it could get to 260 lm/watt, then we have REAL energy savings. Creates a legacy problem Great for dimming. Relatively low environmental impact. Still dealing with BAD manufacturers and marketers.
