A real case:
Recently Dave F. of Los Angeles, CA, purchased 177 LED bulbs for the common area of his 125 unit complex in Orange, TX.
He replaced 65 watt incandescent bulbs with 6 watt LED bulbs. This measured a savings of over 90% on his utility bill for the portion dedicated to lighting. This positive change [...]
The lumens or ‘brightness’ measure is an important one to look at. Incandescent and CFL bulbs shoot light in 270 degrees all around them. LEDs are built to shoot light in 15, 30, 45, 120, or 180 degrees depending on the bulb. The reason is because LEDs are directional lighting. They shoot light in the [...]
What to Look For in a Lightbulb
Although there are other options, including LEDs and halogen bulbs, when it comes to cost, availability, and savings, compact fluorescent bulbs (CFLs) still offer the best value for lighting. You can now find LEDs for around $20, while CFLs average from $2-$10.

There are many LED advantages for home and business use which makes it no surprise that so many people and businesses are now choosing LED lighting option for their needs. When you learn more about these advantages that are available, you will be able to make a decision about whether or not this is the [...]
More and more people are choosing to use LED lights today and for great reason. There are so many benefits to LED lights today that it just pays to make this choice instead of the alternatives that are on the market. Before you can make the choice about whether or not LED lights are right [...]
The history of LED lights leads right up to today when we can’t purchase an electronic device without seeing LED in the description. Years ago this was not the case. As recently as 1900 Electroluminescence hadn’t even been discovered. I’m sure that at the time, this was no great hardship for people, but nowadays it [...]
Studies suggest that a complete conversion to the lights could decrease carbon dioxide emissions from electric power use for lighting by up to 50 percent in just over 20 years; in the United States, lighting accounts for about 6 percent of all energy use. A recent report by McKinsey & Company cited conversion to LED [...]
LED technology is driving the future of lighting with the developments made in the efficacy of white LEDs in the past few years,
As white light is the main driver for general illumination, there is a particularly strong focus on improving the efficiency of white LEDs, which currently outperform tungsten halogen lamps with efficacies from 45-55lm.
Manufacturing [...]
The ‘white’ of white LEDs comes from the narrow-band blue naturally emitted by GaN LEDs, plus a broad spectrum yellow generated by a phosphor coating on the die which absorbs a proportion of the blue and converts it to yellow.
‘GaN’ die are actually InGaN heterostructures, which can produce operational wavelengths from green to ultra-violet by [...]
Are you still using incandescent light bulbs? As we all know that home lighting accounts for about 20% of the average home’s electricity bill. So switching to compact flourescent or LED bulbs will cut down your electricity bill.
Here are the pros and cons for LED:
LEDs LED technology allows for a large amount of light to [...]
