Learn>>Incandescent vs. CFLs - Similarties and Differences This video provides a good overview of the similarities between incandescent and compact fluorescent light bulbs. Typical concerns of people about compact fluorescents are the color of the light and the slight lag before the light turns on. This video shows that these concerns are largely solved in today's compact fluorescent bulbs. Bulbs you saw in this video are available on our site. Shop Now >>Mercury content in CFLs Recently the press has started talking about mercury in CFLs and how dangerous this is. While there is a tiny amount of mercury in each bulb, the dangers that the press brings up are exaggerated. CFLs have about 2.5-5mg/bulb, which would roughly cover the tip of a ball point pen. In comparison, an old mercury thermometer has ~100mg of mercury, and some watch batteries have ~25mg of mercury. Realistically, disposal of broken CFL bulbs can be done by sweeping up the bulbs, putting the pieces in a sealed plastic bag and throwing it in the trash. As long as you don't do anything drastic, like licking broken bulbs, the bulbs are relatively safe. To be extra careful with disposal of broken CFL bulbs follow these guidelines by the EPA. (Disposal Guidelines) Burnt out bulbs can also be brought to local recycling centers. While this cleanup and disposal of CFLs may seem a hassle, a study done by the EPA in 2002 (EPA Study) shows that using CFLs actually reduces the total amount of mercury released into the environment relative to incandescent light bulbs. For light bulbs mercury comes from 2 sources: mercury in bulb & mercury released during electricity generation.
Also, there are CFL recycling centers which reclaim the mercury in the bulbs preventing any from getting into the environment. This is much better than burning coal to generate electricity where the mercury is released into the atmosphere. CFL usage + recycling would net 2.4mg mercury released vs. 10mg for incandescent bulbs. Incandescents overall release more than 5x the mercury into the environment than CFLs!! |
