Fluorescent

The GlowintheDark Flashlight!

Harry's really slow to catch on.

Turn it on turn it off.

But the pay off is really enormous.

The reason that Vibrio fischeri is doing that comes from the biology.

Well, the GlowintheDark Flashlight, that was mine.

I must replace that fluorescent lamp.

Phosphor

Phosphor

That's a third of the U.S. population.

Luminous poisoning? Go on, do what I tell you.

This fluorescent lamp is starting to flicker. We'll have to replace it.

You must steel yourself for a shock, Mr. Bigelow. Well go on, Doctor, what is it you're trying to tell me?

What's the trouble here?

The one thing we need to do is we have to replace these inefficient incandescent light bulbs, florescent lights, with this new technology of LED,

Thermosalinographs, fluorometer, carbon analyzer...

They ushered me down a narrow set of stairs that led to this dirty, dimly fluorescent lit basement.

The GlowintheDark Flashlight!

Now bright, now dimmed, was the moonlight pale,

We're trying to preserve nerves we can't see where they are.

Tell them to prepare a stomach wash for luminous poisoning.

It used to be a weight room, so there were rubber floors below, acoustic tile ceilings and fluorescent lights.

And for that reason, we cover the LED with a phosphor cap.

This bacterium has the special property that it makes light, so it makes bioluminescence,

A firefly?

Hotaru?

And this is what I think is the magic of fluorescence.

But one of the most popular ones involves green fluorescent protein.

We saw the gleam of a distant lighthouse.

His legacy is with us still.

Hotarubi!

Hotarubi!

Hotarubi...

And this little piece was shown just for the spring session.

And now, boom, the tumor labels itself and it gets fluorescent.

Since August 2012, harmful phosphors have been found in the instant noodle package cups from every famous brand sold in China's supermarkets.

Why Hotarubi?

The lighthouse was beaming forth rays of light.

And the cool thing about fluorescence is that it's not only bright, it actually can shine through tissue.

I went down to a depth of 880 feet and turned out the lights.

And I came in half an hour beforehand so I could have it put on and kind of get used to it, and they got it bent so it's not hitting my chin.

Light the lanterns, blow out the lanterns, cover the lanterns.
