Compact fluorescent bulbs (CFB) are eco-friendly lightbulbs where the tube is 'twisted' and are not the conventional incandescent bulbs. CFBs use less energy but can be found in normal wattage ranges. They can be used indoor & outdoors.
CFBs have an expected lifespan of about 7 years. That's right: they are expected to not burn out for 7 years! Because they last SO LONG, and because they use LESS ENERGY, they are a great choice for someone who would like to make small changes to their dwelling to make it more eco-friendly & save on the cost of energy bills.
CFBs also contain Mercury, a toxic element if it enters the blood stream. As long as the Mercury is contained within the glass bulb, it poses no threat to your safety. Because CFBs contain Mercury, they are considered "hazardous waste" and cannot be simply thrown away in the garbage (unlike conventional lightbulbs).
Stores like Home Depot and IKEA have special centers in the stores where you can dispose of your CFBs safely. Also, you can log onto www.earth911.com and find other recycling & disposal places for your CFB bulbs.
CFBs can be found at Home Depot, Lowe's (and most hardware stores), Target, Bed, Bath, & Beyond, and most major big-chain stores.
Consider CFBs for your home or apartment today; save money, and do a small part to help the earth!
