The New York Times disclosed that The Home Depot will sell a 40W LED bulb online for less than $20. This will be the first attempt by LED technology for inexpensive home light sources. The light bulb "Ecosmart" is produced by Lighting Sciences Group and is expected to be available in September. Although the unit price is still high compared to incandescent lamps, the long service life has made LED light sources enter the field of public home applications.
Lighting Science Group said that their adjustable brightness A19 bulbs consume 8W and output brightness from 435 lumens to 570 lumens. Most of the comments on this light bulb have been very good so far, indicating that the brightness is moderate, but there is also a bad review that the light bulb has exploded after being bought back.

In addition to power saving, LED bulbs can be used for at least 20 years and contain no mercury, and many incandescent lamps contain mercury. Some LED manufacturers offer recycling services. In addition, as a cold light source, the application of LEDs in air conditioning systems will reduce the overall load.
Another light source manufacturer, Osram Sylvania, said he plans to launch a 60W LED light source next month. The price has not been determined. The Lighting Science Group will also introduce a 60W LED light source, and the actual energy consumption will be only 9W. Other manufacturers, including Philips and General Electric, are also entering the field of LED residential light sources.
