In 2010, incandescents were 68% of the bulbs installed in U.S. homes. By 2016, that number had declined to 6%.To get more news about led headlight kits, you can visit iengniek official website.
That change has shaken up the industry in a good way. Mark Rea, professor at the Lighting Research Center at Rensselaer Polytechnic Institute, tells Here & Now's Jeremy Hobson that the benefits of LED lights "really make it kind of a slam dunk for a transformation in the way light sources are sold."
He says those benefits include how many lumens per watt LED lights provide, long-lasting capabilities, ease of control, their glow and the ability to have multiple color options.I think there are two touted benefits. One is how many lumens per watt you get out of it. So an incandescent lamp might be 12 to 15 lumens per watt, and depending on the LED you might get 100 lumens per watt. So that's a big jump. And the other is longer life. That depends on the application, but generally speaking incandescent lamp might last, say, six months in your home. These can last up to 10 years. So those are really big differences but there are other benefits that people don't talk so much about. They're easy to control. So you can do some fancy stuff with them whether you put them on a bridge or you want to have a disco. There's no filtering that you have to do. It will directly emit the wavelengths you want so you can have a red one or a blue one or a white one."
"People hate change. That's the first thing. I don't think anybody anticipated what a disruptive technology [this] was really going to be. For 100 years, we've had just a handful of major manufacturers and they pretty well set the standards [and] the policy. And the reason was it was very expensive to try to be in that business. It took a huge capital expense that no one wanted to commit to, to say produce fluorescent lamps or incandescent lamps. With LEDs, they're cheap and anybody can be a lighting manufacturer now. So it's really brought down ... these major players that really set the tone for lighting for literally 100 years. That all changed with LED."
"Incandescent would be outlawed and halogen would also. They can't reach that level. That number was picked primarily to still allow for fluorescent lamps, which are very common still in commercial and some residential applications.
"I don't know if legislation will be needed. If you're getting 100 lumens per watt as opposed to 45 lumens per watt probably the marketplace will just switch naturally, but I can't predict that."
"No. The point I want to make is that they're better than incandescent, from a color [perspective] and the glow and the perception of the light is better now than any of those technologies up to this point."
"I can't think of anything more important! ... We've done studies here, not those market surveys, but laboratory studies and gone to fields and given the choice, people prefer LED to incandescent. That means that people will more readily adopt that technology. And I think that particularly for home and restaurant, the mood that lighting can create makes a big difference in terms of sales. Not specific to LEDs but a fluorescent bulb in a high end restaurant just isn't going to cut it. That's just not going to work."
