Of course this is good news for everyone: from LED innovators (my research group) and customers (everyone). Some statistics I read in their press release were actually pretty interesting.
- Less than one-half of Americans (43%) have at least one LED bulb in their house, compared to China (80%), Russia (65%) and Sweden (61%) 
- Only one-third (34%) of Americans say LED lights provide similar lighting quality to incandescent bulbs, compared to China (77%) and Russia (61%) 
- More than 1/3 (34%) of people don’t know that LED bulbs use less energy 
- Only 27% of people know that these bulbs last 20 years 
- When told of LED savings, 86% of Americans say they’re interested in switching

Despite efforts from the US Department of Energy to inform consumers about the benefits of LED lighting, including standardized test procedures and packaging labels, or LED rebate programs, these surveys show that many Americans are still lack knowledge of the benefits and properties of LEDs.
I understand it takes time for technology to become mainstream, and the price of the products need to come down for sure. Assuming the price comes down to <$10 a bulb, what else needs to happen for more people to catch on to the benefits and modern advancements in LED products? Is this even an engineering problem anymore or is it a marketing problem?
