You can get ones made of glow-in-the-dark plastic, but the glow goes after an hour or so out of the light.
My idea combines a very low frequency (0.3 ~ 0.1HZ) IC flashing low wattage LED where the plastic cap is made of glow in the dark plastic. That should produce an interest effect and a persistent
glow, and yet not drain battery powered devices too quickly.
The idea is particularly useful on things you need to find in the dark: flashlights, key chains, smoke hoods, buttons, etc.
The system is simple, small, cheap, uses proven technology and requires no clever circuitry or re-engineering to adapt existing products.

I voted for, but I have to wonder what it would be like staying in room with a bunch of this stuff. |

Make children's toys and women's shoes with this feature and there will be a lot fewer nighttime injuries in the world. |

Hey guys, good to see ya. |

My question is what is it in the glow-in-the-dark plastic that makes it glow? I know that phosphorescent items take the UV radiation and release visible variation. If glow-in-the-dark does the same thing, then the LED would not put out enough UV radiation to light up the GITD item. |
|
| |
Even if that's true (I have no idea), they make LEDs that have UV output. |
|
| |
I have two of those UV LEDs. They're marketed as keychain money detectors. |
|
| |
I put a glow in the dark keychain under
my shortwave UV lamp and instead of
the eerie green glow I got an eerie
orange glow. |
|
| |
Nice idea, it should work. + |
|
| |
This type of device is well-known in the flashlight
community, with the
omission of the GITD phosphor. You simply run an
LED at an extremely low current and it produces a very
small amount of light, extremely efficiently. |

I like to imagine the flashlight community has their meetings
in a very dark room. |
