LampRecycle.org was developed by the National Electrical Manufacturers Association (NEMA) as a way to provide businesses and consumers a one-stop resource for recycling lamps. On the home page of the website you can enter your zip code under “Find a recycling location” to find a recycler close to your home or office, learn about the difference in lumens and wattage, how to clean up a CFL bulb and hear about new regulations in 2012 that will make the old 100-watt incandescent bulbs obsolete.
