# How to dispose of fluorescent bulbs and CFLs

Compact fluorescent lamps (CFLs) and tube fluorescents contain mercury. The amount in one bulb is small, but trash trucks and landfills are the wrong place for mercury. Most U.S. cities and retailers therefore steer residents to **HHW** or **retail take-back**, not the blue cart.

LED bulbs are a different product — see LED bulbs. Incandescent bulbs are usually trash — see incandescent bulbs. This guide is about mercury-containing lamps.

Why fluorescents are special

Mercury vapor is released when a lamp breaks. Programs exist to:

Wishcycling a tube into mixed recycling often means the lamp breaks on the sorting line.

Best drop-off options

Retail take-back

Many hardware and home-improvement stores host CFL bins near the entrance. Tube acceptance varies — four-foot tubes may need HHW instead. Call the store; bin programs change.

Household hazardous waste

County HHW facilities commonly list fluorescent lamps and CFLs. Bring lamps intact in a box. Some sites also take ballasts; ask whether PCB ballasts from old fixtures have separate rules.

Municipal e-waste or lamp events

A few cities collect lamps on e-waste days. Do not assume every electronics event wants four-foot tubes — check the accepted list.

Storing bulbs until you can drop them off

If a bulb breaks

Treat it as a small mercury incident, not a normal sweep-up:

Commercial spills and many broken tubes are above DIY scope — call local guidance.

Ballasts, fixtures, and retrofit kits

Old magnetic ballasts may contain PCBs. Do not smash them open. Ask HHW or a lamp recycler how they want ballasts packaged. Empty aluminum fixtures without lamps often go as scrap metal or bulky metal — remove the lamps first.

What not to do

How to use DumpRegistry

One hardware-store CFL bin trip often clears a drawer of old bulbs. Tubes from a garage remodel usually need the HHW lane — plan that with paint and batteries on the same errand.
