Don't be afraid of mercury in new efficient lighting

Colder weather and shorter days mean more time inside, and it will be darker, sooner, thanks to Sunday's end of Daylight Saving Time.

That means the lights will be on for longer hours, but that doesn't necessarily mean bigger electric bills.

That's because compact fluorescent light bulbs are becoming cheaper and more easily available in a wider variety of applications. Some of them are even able to able to handle a dimmer switch, but not the run-of-the-mill version available most places.

And while they're still more expensive that conventional incandescent bulbs, they're well worth it, because they last 10 times longer and use about 75 percent less energy while producing a comparable amount of illumination.

They say it takes money to make money, but CFLs are one example where it takes money to save money.

A typical 20-watt CFL costs about $3 each or $2 in multi-packs, but it will pay you back in lower energy costs in as little as eight months, depending on the price of electricity. After that, it's pure savings, probably for years.

Yes, it's true they do contain mercury, but only about 5 milligrams in each bulb, which is not a health risk when the bulbs are properly used, handled and disposed of, according to the Nebraska Public Power District.

If a CFL breaks, it is safe for you to clean-up the broken bulb. Follow these recommended Environmental Protection Agency guidelines:

* Open a window and leave the room for 15 minutes

* Use stiff paper or cardboard to scoop up the fragments and powder

* Wipe the area clean with a damp paper towel

* Place the broken bulb and cleaning materials into a plastic bag and seal

* Wash your hands

* Dispose of broken bulb and cleaning materials properly
