  C. A Bright Future For New Fluorescent Lighting

Narrator: This is Science Today. There's a bright future for a new type of fluorescent light bulb. Researchers at Los Alamos National Laboratory are working to develop a fluorescent light bulb which would have longer life and the ability to be dimmed by conventional switches. Team leader Marion Scott explains the primary difference between the old and new bulb.

Scott: The conventional bulb involves the use of mercury and in the new lightbulb that we're talking about, there's no mercury inside, in fact, there's no gas inside at all. It's just a fiber which is emitting electrons.

Narrator: And Scott says the lifetime of conventional bulbs is usually determined by how much degradation takes place by gas generated ions.

Scott: The new bulb would have no gas, no ions and so no degradation of the cathode from that mechanism.

Narrator: Since the research is still in the early stages, Carey says it may take a while for this new fluorescent light bulb to ‘come to light'. For Science Today, I'm Larissa Branin.
