Once-Scorned Light Bulbs Are Advancing

C.F.L.’s or compact fluorescent light bulbs, require one-quarter the energy from coal-fired power plants that incandescents do.

However, light bulbs are so easy to break. The amount of mercury contained in a C.F.L. is roughly equivalent to the amount of ink on the tip of a ballpoint pen and about one-fifth the amount in a watch battery, the council’s paper says. But the bulbs can leak mercury vapor when broken, so ventilation is important when cleaning a broken bulb, the council says in its paper.

Some manufacturers now produce C.F.L.’s with protective coating; the EcoSmart Shatter-Resistant C.F.L. is one example.

So for those proceeding with caution on C.F.L.’s, the light is now green.
