The Truth Behind LED Lighting
LED Lamps for New and Retro-fit Applications
Why Choose LED lamps?
There are many things to consider: energy efficiency, lamp life, color/temperature, disposal, and dimming. LED lamp efficiency: All LED lamps are not created equal. There are some basic facts to review before purchasing a LED lamp or fixture. The basic reason to switch to LED is for energy savings and longer lamp life. For a lamp to be considered energy efficient it should be rated at 40-lumens per watt or higher, this is called efficacy. Most high quality LED fixtures today are rated at 50-65 lumens per watt compared to an incandescent rated at 10-35 lumens per watt. The average lamp life of an LED is 35,000 -60,000 hours compared to incandescent rated at 2,000 hours. LED lamps do not use mercury like some other energy efficient lamps so there no hazardous waste when behind disposed.
Color Temperature and Rendering
Color temperature and color rendering is one of the main reasons people have not switched to LED lamps. Most people prefer the lower color temperature of incandescent lighting rated at 2700K – 3100K. LED lamps have changed over the past year and now it can be difficult to tell the difference between the color temperature of incandescent lamps and LED lamps. Be aware that typically the lower the LED color temperature the less energy efficient the lamp.
Below is a chart that is supplied with most quality lighting fixtures or lamps. It is always good to compare the color accuracy, color temperature, and most important lumens per watt. Since the main reason for upgrading to an LED lamp is energy efficiency the lumens per watt is the most important fact. We would recommend you find a lamp rated at 60 lumens per watt or higher, 80 CRI or higher, and a 2700-3100K color temperature.
