While the material costs for each light

While the material costs for each light are estimated to be anywhere between $400-550 per unit, making the project costly, the LED lights will most likely outlast the existing 104 CFL lights that have begun to decline in quality. LED lighting has more than double the efficiency of CFLs, according to a New York Times article from May 2009.

LED lights turn on more quickly than CFL lights and, unlike CFLs, do not contain mercury, the New York Times article said. Because they also last longer than CFLs, they are considered safer for the environment.

LED lights may be environmentally friendly,dsttマジコン You can use different light bulbs depending on where and what you are going to be using it for. One of the newer types of light bulb that you may want to use is the LED type. but they may not be as people-friendly.led lamp Since computers are used by everybody these days including the young and old, a LED computer monitor sounds like a good gift you could give away. A Feb. 9 Los Angeles Times article noted a study from the University of California-Irvine that found some colored LED lights contain lead, which is toxic to the human body. If these lights become damaged or broken, they could become harmful to anyone around them, including installation and maintenance crews and users of the parking garage.led light bulbs One of the most basic devices that run on LED is a flashlight. Older models relied on a single bulb to produce the light needed to make one work.

However, only the entrance and exit signs to the garage use colored lights. The remainder of the garage uses white light, which does not have lead, according to the study.

Peterson said there are no set plans for when LED lights will replace the CFLs,table lamps Most solar lights are placed in strategic locations outside where they can charge for the majority of the day. Some of these lights are used for security purposes. as the Physical Plant is still determining the cost-efficiency of the project and how safe parking garage users will be. He is looking for student, faculty and staff input about the possible change.

Several students who were asked their opinion about the switch to LED lights either didn't have one or complained about the location of the parking garage.

"It's in an inconvenient part of campus," junior Irma Fernandez said.energy saving light Since LED bulbs use very little power, they drain the batteries very slowly. Therefore, solar LED lights can last 10 hours or more.
