"Traditional incandescent bulbs are simple and non-toxic — they’re made from bits of glass, some metal, and a tungsten filament. When they burn out, you can safely discard them in your normal trash can.

Dead LED bulbs, on the other hand, are e-waste. Like old computers, they contain chips and other electronics that need to be properly recycled by a professional e-waste processor. If they’re sent to a traditional landfill, they can potentially leach dangerous chemicals into the soil."

I think about this everytime i change a lightbulb that did not last for even 2 years.
