How to Recycle Light Bulbs (Incandescent)
Tungsten filament and halogen bulbs. The one lighting product where the trash is the right destination, and the one most often confused with mercury-bearing CFLs.
Quick answer
Trash. That is the correct answer. Incandescent and halogen bulbs hold too little glass and metal to be worth recovering, and they contain no mercury. Wrap a dead bulb and bin it. The bulbs that must not go in the trash are CFLs and fluorescent tubes, which contain mercury and are illegal to landfill in several states. Before you go, confirm that a local recycling center accepts the material in its current condition.
- Recycling route
- Special handling
How to Prepare
- 1Let the bulb cool fully before touching it
- 2Check what kind it is, since CFLs and tubes must not go in the trash
- 3Wrap the bulb in paper or slip it into its replacement's packaging
- 4Put it in the household trash, not the recycling bin
- 5Sweep up a broken bulb rather than vacuuming, and wrap the glass securely before binning it
Where to Recycle
- Household trash, wrapped
- County household hazardous waste programs, for CFLs and tubes instead
- Hardware store take-back bins, for CFLs where offered, calling ahead first
Special Instructions
Incandescents and halogens go in the trash because the amount of glass and metal in them is minimal and hard to recover, not because anyone is cutting corners. Mercury-bearing lamps are different. CFLs contain roughly 4 milligrams of mercury each and linear fluorescent tubes hold more, so both must be recycled rather than binned, and both are banned from landfill in California, Maine, Massachusetts, New Hampshire, Vermont, and Washington. LEDs are a third category and are handled as electronics rather than glass. On retail take-back, be skeptical: EPA's own guidance says to check directly with the store first, because not all locations in a chain participate and some accept only certain bulb types. Home Depot has described free CFL bins near store entrances, though its current guidance only tells you to check locally, and Lowe's program status could not be confirmed. Your county household hazardous waste program is the reliable route.
Environmental Impact
These bulbs are disappearing by rule. The Department of Energy's efficiency standard, requiring general service lamps to reach at least 45 lumens per watt, took effect on July 25, 2022, with retailers fully compliant by the summer of 2023. It is a sales prohibition on inefficient lamps rather than a ban on a technology, and specialty bulbs sit outside the definition. The next step is already scheduled: compliance with tighter standards is required from July 25, 2028, at efficacy levels CFLs cannot meet, which points the whole category toward LEDs. Replacing a working incandescent with an LED saves far more energy than anything that happens to the old bulb at end of life.
Sustainable Alternatives
- Switch to LEDs, which cut both energy use and replacement frequency
- Keep working incandescents in low-use fixtures rather than binning them early
- Recycle CFLs, fluorescent tubes, and LEDs through the right channel instead of the trash
