Expensive EarthTalk: Are there health or environmental issues with LED lightbulbs, which may quickly replace compact fluorescents because the inexperienced-pleasant light bulb of choice? Indeed, energy-saving LED bulbs (mild emitting diode) lighting does seem to be the wave of the future proper now, given the mercury content and mild quality points with the present king-of-the-hill of inexperienced bulbs, the compact fluorescent (CFL). LEDs use considerably less vitality than even CFLs, and do not contain mercury. And so they are becoming economically aggressive with CFLs at the purpose of buy whereas yielding superior high quality lighting and energy bill financial savings down the road. However LEDs do have a darkish aspect. A examine published in late 2010 within the journal Environmental Science and Technology found that LEDs include lead, arsenic and a dozen other doubtlessly dangerous substances.
