Posted June 06, 2018 08:04:08 A new research study from the University of Victoria and the University at Albany suggests that a simple LED light system would not be a good solution to the problem of indoor lighting problems in homes.
The study, published in the journal PLOS ONE, examined indoor lighting and its impacts on the health and quality of life in the United States.
In the study, researchers found that the number of people living in an urban area was growing rapidly, and that indoor lighting had become a big problem.
Researchers found that about 1 in 4 Americans currently lived in an area where at least one light had to be switched on at least three times a day.
And many of those lights were emitting a greenish-yellow light, which is a common cause of indoor light pollution.
“If you were to turn on an LED light bulb and add a light switch to the light socket, you’re going to have more than three times the light output,” said Dr. Rebecca Farr, an assistant professor of environmental health and safety sciences in the College of Science and Engineering.
“And you’re not going to get that back, so the question is, why would you want to do that?”
To solve the problem, the researchers wanted to see if they could figure out a way to create a light that would generate enough light to power the LEDs inside the bulbs.
To do this, they used a series of LED bulbs with different wavelengths and a combination of LED lights that were all set to be turned on simultaneously.
“We designed the bulbs to produce a spectrum that was not too green or too red, so that when they were turned on they wouldn’t emit any light that was too green,” said Farr.
“But we didn’t want them to have too much light at the same time, so we set them to emit only the light that we needed for the LEDs.”
When they turned the lights on, the light intensity varied with the frequency of the LED light, so they could control how much of the spectrum they would get.
To test the light’s ability to generate enough power, they tested the lights in different locations, including in the back yard, in the hallway, and in a window.
They also compared the results of the LEDs to other light sources, such as fluorescent lights, which emit red light.
The researchers found, for the most part, that the LED lights generated more light than the fluorescent bulbs they were replacing.
“So the idea that you could replace all the fluorescent light bulbs with LED bulbs and have no problem producing enough light for the LED bulbs was pretty much the same thing as what we would do in the real world,” Farr said.
“It wasn’t really a problem.
In fact, the energy produced by the LED bulb was about twice as good as the light produced by fluorescent bulbs.”
However, the results did not indicate that LED lights were as efficient as fluorescent lighting.
Instead, the lights produced less light than other sources.
In fact, for most LED lights, the amount of light they produced was about 10 times the amount that the fluorescent bulb could generate.
This was true even for low-intensity LEDs, which are less efficient than higher-intensity bulbs, such that the energy required to light a bulb is about 1.5 times that of the energy generated by a low-amplifier bulb.
This means that if you replace a standard fluorescent light bulb with an LED bulb, the total energy output will be more than 10 times greater than the energy needed to light that bulb.
“I think it is pretty clear that LED lighting is a relatively inefficient way to light your home,” Farg said.
And while the results indicated that LED light bulbs were the least efficient, the research does not say that the bulbs were not worth replacing, just that they could be better.
“This doesn’t mean that LEDs are not going be an efficient alternative to fluorescent lighting, but I think the research shows that LED bulbs are not necessarily as efficient,” FARR said.
The next step for the researchers is to find a way for LED bulbs to be used in other places, such in places that don’t have a lot of people, such to replace inefficient fluorescent lights.
The research is also promising for other types of lighting, such LED lights for street lamps.
“When we replace a fluorescent bulb with a LED, we are basically replacing a light bulb that is more energy-intensive and has more noise and vibration, so this may be a better choice for many of the more remote locations where there are no people,” Fars said.
Farr is the lead author on the paper, which was published in PLOS One.
The results are based on a survey of 2,000 people in a variety of locations in North America and Europe.
