Where can I recycle fluorescent light bulbs?

Call your local "BFI" or similar waste haulers and see if they have provisionsn for disposal of these items.
It's a shame, but I cannot see spending great amounts of money to dispose of these things when no one wil take them locally, so I place them in plastic shopping bags and dispose of them with the regular garbage.
There are only trace amounts of mercury in any of them, about 5mg, the size of the head of a straight pin. A standard medical thermometer contains 500mg of mercury.

Home Depot takes used, unbroken spiral CFL bulbs. Place in plastic bag and carefully leave in their recycling bin, often near Customer Service desk. For long, tube type flourescent bulbs, contact your town's trash collection department. Some towns collect these at their recycling depots, as long as you can prove residency in that town.

I don't know about websites, but I'm planning to try to recycle mine at the local landfill's hazardous waste recycling area,. Maybe your local landfilll has recycling for the lights?

Try going to www.earth911.org enter your zip and click on the item to recycle and they will provide a list of whats available in your area.
You can also contact a trash hauler in your area they often get calls about this type of thing and can probably help you find a place.
Talk to stores in your area that sell cfls some will take back the old ones.
Look into your local government they will also be able to help you out or steer you in the right direction.
