Fluorescent lights use electric current to excite Mercury atoms, which emit UV light. The tube part of the light is covered in phosphorescent material, which is excited by the UV light the mercury produces, and emits visible light. The reason they glow is because it takes a while for an excited mercury atom to emit the UV light, and it takes even longer for the excited phosphorescent molecules to emit all of their excess energy and return to their normal energy levels, also called the ground state. The path of the energy is Electricity -> UV light-> Visible light-> your eye
What else can I help you with?
how does a glow glow in the dark and what makes it glow?
Glow in the dark items contain phosphors, which are materials that store light energy when exposed to light. When the lights are turned off, the phosphors slowly release this stored energy as visible light, creating the glowing effect.
What happens to the powder when the light was off?
If the powder is luminescent or phosphorescent, it will glow in the dark for a period of time after the light is turned off due to stored light energy being slowly released. If the powder is just regular powder without any special properties, it will remain dark once the light is turned off.
How do you change a stuck fluorescent light?
Make sure the light switch is turned off before attempting to change the fluorescent light. Wear gloves to protect your hands while handling the light bulb. Twist the bulb counterclockwise to remove it, then insert the new bulb and twist it clockwise to secure it in place.
Can some minerals glow under ultraviolet light?
Yes, some minerals contain compounds that fluoresce or emit visible light when exposed to ultraviolet (UV) light. This phenomenon is often seen in minerals such as calcite, fluorite, and willemite, which can exhibit bright and colorful fluorescent responses under UV light.
Can a light bulb blow out if it's turned off?
No, a light bulb cannot blow out if it is turned off. Blown light bulbs occur when they are turned on due to the filament burning out or electrical issues.

Why do fluroescent lights glow in the dark when swiched off?
A fluorescent tube contains (when operating) a plasma, and this excites phosphors coated on the inside of the tube. Some of these phosphors are phosphorescent, that is they will glow in the dark for a while due to being exposed to light. But that glow will soon cease. Other phosphors are fluorescent, that is they will glow only while excited. So the glow you observe is due to the phosphorescent particles in the coating, and they will soon diminish in brightness.
What is life expectancy of fluorescent tube light?
The average life expectancy of a fluorescent tube light is around 10,000 to 15,000 hours of use. However, this can vary depending on the quality of the light fixture and how frequently it is turned on and off.
When was The Fluorescent Light Glistens Off Your Head created?
The Fluorescent Light Glistens Off Your Head was created in 2005.

Why does a television when turned off still have its screen glow in the dark?
Phosphorus
How does a pickle glow?
A pickle can glow due to the phenomenon of fluorescence. When a pickle is placed under a black light, the fluorescent compounds in the pickle's skin absorb the light energy and re-emit it at a longer wavelength, producing a glowing effect. This makes the pickle appear to glow in the dark.
How can I change a fluorescent light bulb in my fixture?
To change a fluorescent light bulb in your fixture, first make sure the power is turned off. Then, gently twist and remove the old bulb. Insert the new bulb by twisting it into place. Finally, turn the power back on to test the new bulb.
How do eyes glow?
It is the reflection of the light off of the retina.
What are the positive points of ulteraviolet rays?
Ultraviolet rays can be used as for fluorescent lamps as certain chemicals glow when they absorb ultraviolet. In fluorescent lamps, the sindide of the tube is coated with a white powder that gives off light when it absorbs ultraviolet. The ultraviolet is produced by passing a current through a gas in the tube.
How can I change a fluorescent light bulb?
To change a fluorescent light bulb, first make sure the power is turned off. Then, gently twist the bulb counterclockwise to remove it from the fixture. Insert the new bulb by twisting it clockwise until it is securely in place. Finally, turn the power back on to test the new bulb.
