The Case for LED Lighting: Low Energy Use (Low Carbon Emissions), Longer Life (Less Maintenance), No Mecury (Hazardous Waste), Low Heat (Fire Safety and Innovation)
The Light given off by a particular wattage Incandescent Bulb has been the defacto standard for discussing lighting. When more energy efficient lighting has emerged, more light is provided by the same wattage. The wattage is important because it is the amount of electricity the lamp uses.
As Lighting Tubes were the innovation brought about by Fluorescent Technology and direct replacement Compact Fluorescent Lamps followed later so, it has been with LED Lighting.
LED Christmas Lights, torches and strip lighting has been well established by the time direct replacement LED Bulbs and Tubes have been developed.
Mid 2011, the US introduced a new Lighting Labelling Standard
Under the new rule, the back of each package of light bulbs will have a "Lighting Facts" label modeled after the "Nutrition Facts" label that is currently on food packages. The Lighting Facts label will provide information about:
* energy cost;
* the bulb’s life expectancy;
* light appearance (for example, if the bulb provides “warm” or “cool” light);
* wattage (the amount of energy the bulb uses); and
* whether the bulb contains mercury. - http://www.ftc.gov/opa/2010/06/lightbulbs.shtm
Lumens let you buy the amount of light you want. So when buying your new bulbs, think lumens, not watts.
The brightness, or lumen levels, of the lights in your home may vary widely, so here's a rule of thumb:
* To replace a 100-watt incandescent bulb, look for a bulb that gives you about 1600 lumens. If you want something dimmer, go for less lumens; if you prefer brighter light, look for more lumens.
* Replace a 75W bulb with an energy-saving bulb that gives you about 1100 lumens
* Replace a 60W bulb with an energy-saving bulb that gives you about 800 lumens
* Replace a 40W bulb with an energy-saving bulb that gives you about 450 lumens. - http://www.energysavers.gov/your_home/lighting_daylighting/index.cfm/mytopic=11976
Comparative Lamp Technology Lifetime
manufacturers have begun using the L70 language, stating that their white LEDs "are projected" to have lumen maintenance of greater than 70% on average after 50,000 hours when used in accordance with published guidelines.
|Light Source||Range of Typical Rated Life (hours)* (varies by specific lamp type)||Estimated Useful Life L70|
|High-Power White LED||35,000-50,000|
