Energy Star Certified Light Bulbs is a resource for finding and comparing Energy Star qualified lamps. A similar program in the United Kingdom (run by the Energy Saving Trust) was launched to identify lighting products that meet energy conservation and performance guidelines. [23] Ushio released the first LED filament lamp in 2008. [24]
The intent of the program is to reduce consumer concerns about efficient light bulbs due to variable quality of products. [83] Those CFLs with a recent Energy Star certification start in less than one second and do not flicker. Energy Star Light Bulbs for Consumers is a resource for finding and comparing Energy Star qualified lamps.
Luminous efficacy can be normalized by the maximum possible luminous efficacy to a dimensionless quantity called luminous efficiency.The distinction between efficacy and efficiency is not always carefully maintained in published sources, so it is not uncommon to see "efficiencies" expressed in lumens per watt, or "efficacies" expressed as a percentage.
EISA 2007 set new performance requirements for certain common light bulbs, requiring that these bulbs become approximately 25-30% more efficient than the light bulbs of 2008 by 2012–2014. Overall, the intent of this was to bring into the market more efficient light bulbs.
Available in numerous spot and flood beam spreads. Like all light bulbs, the number represents the diameter of the bulb in 1 ⁄ 8 of an inch. Therefore, a PAR 16 is 51 mm (2 in) in diameter, a PAR 20 is 64 mm (2.5 in) in diameter, PAR 30 is 95 mm (3.75 in) and a PAR 38 is 121 mm (4.75 in) in diameter. A package of four 60-watt light bulbs
The energy-saving T12 lamps are made to operate on ballasts designed for 40-watt F40T12 lamps, though some F40T12 ballasts are not be designed to operate these lamps, and can overheat if energy-saving lamps are used. Running an energy-saving T8 tube with a ballast for T12 will reduce lamp life and can increase energy consumption. [9]
