LED bulbs appear poised to displace compact fluorescents (CFLs) as the king-of-the-hill of green bulbs, but a study published in late 2010 in the journal Environmental Science and Technology found that LEDs contain lead, arsenic and a dozen other potentially dangerous substances. (Thinkstock)

As the future gets dimmer for traditional incandescent light bulbs, and compact fluorescents (CFLs) fall out of favor due to their toxic mercury component, light-emitting diodes, or LEDs, are beginning to come on strong. LEDs, which are clusters of small bulbs that come in many shapes and sizes, last five times longer than CFLs and 40 times longer than incandescents and use much less energy.
