Mercury scare

Mercury scare

Small amounts of mercury are used in the manufacturing of CFL bulbs. Each contain between 4 and 5 milligrams - enough to fill the period at the end of this sentence. So long as the bulb is intact, the mercury poses no threat. When a bulb breaks, experts recommend opening windows, gently sweeping up the parts remains, and keeping young children away.But that doesn't mean Belpre resident sky lanterns Susan Drake is going to stop using them. The potential risks, however, aren't worth avoiding the new technology, said Ms. Kweller."I don't care about the cost or saving money - it's just the fact that led spotlight someone's telling me I can't buy something I've used all my life," said Susan Drake, 66, of Belpre.

"We understand concerns about mercury,He wrote on social networking site Twitter: "Frideswide Square at Oxford R4ds station working well this morning with no traffic lights. Long may it continue!" but people are only exposed if the bulb breaks and the amount is one one-hundredth what you would find in an old-fashioned thermometer," she said.

Mercury concerns may also be a thing of the past, as even more efficient and longer-lasting light-emitting diode, or LED, bulbs come on the market.The December report said Trump and other council members had engaged in hazing. Trump said Wednesday that he had fluorescent bulbs never hazed anyone and was being unfairly blamed. Ms. Kweller said the amount of mercury used in the manufacture of CFL bulbs is declining, as well. But CFL bulbs may already be approaching obsolescence.

Dim prospects

Dimmable lighThe new class of optical fiber, which allows for a more effective led lighting and liberal manipulation of light, promises to open the door to more versatile laser-radar technology.t fixtures are efficient, allowing the user to cut down the energy, and the lighting, to whatever is necessary. People with dimmable fixtures are finding that they don't work with most CFL bulbs. Even "dimmable" CFL bulbs, which cost $10 or more each, often don't work properly, said Don Fisch showroom manager for Friedman Electric in Scranton.

"They are getting better, but they still don't work the way that people are accustomed to," Mr. Fisch said.

Halogen lights, an adaptation of incandescent technology, are dimmable and use less energy.
