After reading an article from Daily AD covering two companies producing LED bulbs that mimic the warm light and filament look of an incandescent light bulb I started thinking about the advent of LED lighting. I use LED bulbs in my own home whenever possible because I like the color of the light better than compact fluorescents – but don’t ask me what the color, or the lumens, of the bulbs are because I don’t know! And what is a lumen anyway?
If you are curious about LED lighting as well, then the above slideshow is the HOUZZ Story for you. After reading What to Know About Switching to LED Lightbulbs I understand a little better what a lumen is (the short answer: it’s the amount of visible light given off by a bulb) and there’s a handy chart in both the article and slideshow above that compares incandescent watts to LED lumens.
There’s also a lengthy discussion about the color of light. The Correlated Color Temperature, or CCT, is the color of light emitted by a bulb. The Color Rendering Index, or CRI, is a measurement of how accurately a light source shows color rated on a scale from 0 to 100. Click through the slideshow to the chart that demonstrates how the CRI of lighting can change the look of skin tone. The higher the CRI, the more natural skin tone looks. The CRI deals with how authentic the colors appear in bulbs, whereas the CCT reports how blue or yellow light actually is. If you purchase LED bulbs that features the Energy Star logo on their packaging, those bulbs’ CRI will be 80 or above. Energy Star will not certify any LED bulb below 80 CRI. That takes some of the guessing game out of what to purchase since not all bulb manufacturers print this information on their labels.
Check out the What To Use And Where section for suggestions on light colors to use for ambient light sources, for dedicated reading sources and specialty lighting. Also did you know that LED lighting is better for wine storage? The bulbs emit little heat and the UV light emitted by fluorescents can be damaging to wines.
After reading What to Know About Switching to LED Lightbulbs several of my own questions were answered and I have a better understanding why I prefer LED bulbs. I hope this article helps demystify LED lighting for you as well.
