The 2007 energy law required manufacturers to produce bulbs that are more energy efficient than incandescent bulbs
. In 2012, bulbs in the 1490 lumen to 2600 lumen range--the equivalent of a 100-watt incandescent--cannot consume more than 72 watts. In 2013 and 2014, efficiency levels for less-bright Dell inspiron 9300 Battery bulbs go into effect.The Osram Sylvania-sponsored survey found that consumer awareness around the mandate has grown over the past year. Thirty-six percent of respondents said they were aware of the mandate, a 10 percent increase from last year.Over half of respondents have evaluated bulbs other than incandescents and 81 percent have heard of LEDs, with about 9 percent using them. After incandescents, CFLs are the most-used type of bulb, followed by halogens.Thirteen percent of respondents said they plan to hoard 100-watt incandescent bulbs and 28 percent expressed worry about losing these traditional bulbs.The trend toward more efficient lighting is stronger Dell inspiron 9400 Battery among business customers, according to a survey published in September by Osram Sylvania. Over 70 percent have evaluated efficient lighting and 73 percent said they are evaluating or plan to use LED lighting.Lighting manufacturers are embracing LED technology because it offers a promising path toward steady efficiency improvements. The light quality of general-purpose LEDs and brightness has gotten to the point where manufacturers can market them for many uses.Compared to EnergyStar-certified CFLs, LED bulbs are slightly more efficient when measured Dell inspiron b120 Battery on lumens per watt and are designed to last much longer--sometimes over 20 years.
