Discarding bulbs incorrectly risks cuts, chemical release, or fire in waste trucks. Treat each technology according to local rules — they are not interchangeable.
LED bulbs
LEDs carry circuit boards but no liquid mercury. Many municipalities allow them in household trash, yet recycling through big-box take-back bins is greener and keeps e-waste metals recoverable.
Compact fluorescents (CFLs)
CFLs contain trace mercury vapor. Seal spent bulbs in a plastic bag and deliver them to hardware store collection towers or hazardous-waste drop-off days. Never crush them in curbside bins.
Incandescent and halogen
These are largely inert glass and metal. Where trash pickup permits, wrap shards in newspaper to protect sanitation workers. Consider recycling the metal base if your center accepts mixed glass.
Linear fluorescent tubes
Four- and eight-foot tubes belong in commercial recycling streams. Businesses face tighter documentation; homeowners should still avoid tossing tubes into open dumpsters.
While fixtures are open
Bulb swaps are the perfect moment to dust globes, wipe switch plates, and vacuum fan housings on ceiling fixtures — quick wins that brighten rooms without a full remodel.
