The study — which evaluated not only the use but also the manufacturing, transport, and disposal of LED, CFL, and incandescent lamps throughout each product lifecycle — found that LEDs have less negative environmental impacts than incandescent bulbs and a slight edge over CFLs. In general, lamp models in the study had levels of federally-regulated elements below most state landfill restrictions. Components in the lamps that exceeded thresholds were the screw bases, drivers, ballasts, and wires or filaments.
The existing CFL lamp also offers an important alternative. The days when they were heavy, ugly and pricey have long gone. Colour variations are also available and increasing numbers can also be dimmed.
Well known brands offer the best all round quality. They are ideal for areas where lighting is left on for longer periods such as halls, landings and porches.
However a number of concerns still exist regarding CFLs. These lamps contain minute amounts of mercury, which is needed to create light in an efficient way. Despite the fact that the mercury used would fit on the tip of a ballpoint pen, there is a justified worry about this mercury being disposed of in the ground. However, mercury is also omitted in the atmosphere from the power system, and the mercury contained in lamps need to be weighed against that emitted from power plants.
Studies show that indirectly the additional energy usage of incandescent bulbs is responsible for more mercury entering the environment than that is contained in a CFL. Both these factors favour the CFL. Huge savings can thus be made in the way we are lighting our offices, roads, shops and factories. It would be a real shame, if we let our nostalgia for a century-old, inefficient bulb, obscure the need to switch to more energy efficient technologies.
Why we need to get rid of incandescent bulbs. Recording and presentations from seminar now on-line. Paris 16 May This energy increases utility costs and is responsible for creating higher levels of greenhouse gas emissions. The energy saved by replacing all incandescent bulbs with LED technology equals the electricity used by 24 million American homes!
The U. A section of EISA established new efficiency standards for light bulbs. Many incandescent and halogen bulbs commonly used by consumers today do not meet the requirements of this act. These include A-style Edison-style 40, 60, 75, and watt incandescent bulbs and halogen PAR lamps greater than 40 watts, which were phased out from to Now that most household incandescent bulbs have been phased out, what will you do for your next lighting choice? In the end, the choice is yours.
You may replace each dead bulb with a CFL. LEDs, however, often offer compelling financial and environmental reasons to make the switch.
Furthermore, with the cost of many LED bulbs swiftly dropping and with the suite of rebate programs now popping up across the country, LED bulbs are more incentivized than ever before. If you are curious about how much you could save by switching to energy efficient bulbs, please review the calculations and table below.
