Absolutely. That's why they discontinued manufacturing the unicorn of all low beams; the 9500HID installed by the Ford/Loncoln-Mercury(Lincoln MK 8, Cougars...)and some other car brands. Mercury is toxic and a hazard to the environment and health says the EPA. Even though it contains about as much mercury as a thermometer that a human sticks in their mouth(...and other places...) to take their temperature.Go figure.Total hypocrasy.
In a fluorescent light bulb there is usually a drop of mercury. That mercury vaporizes as the bulb warms up and it becomes gaseous, enhancing the electron interaction through the bulb, making it brighter.
Hg = Mercury
fluorescent bulbs have mercury in them. There are heaters at the ends of the bulb that vaporizes the mercury to allow the light to be produced ( the fluorescence on the inside of the bulb is what actually glows). If the bulb is cold you do not get the ionization of the mercury to cause the fluorescent powder inside the bulb to glow, or it just glows a small amount.
Compact fluorescent light bulbs contain mercury. (For that reason, it is important to be very careful with a broken compact fluorescent bulb, because mercury is highly toxic.) Most other kinds of light bulbs do not contain any significant amount of mercury.
Fluorescent light bulbs have a gas inside of them called Mercury. The way that the light bulb works is that it uses electricity to "excite" the mercury atoms. This causes the mercury atoms to give of short wave ultraviolet light. this causes a phosphor which is any substance that can illuminate to fluoresce or emit light.
No a light bulb does not use chemical energy. Even though it uses the chemical mercury to create light. Hope this helps =)
yes there is in the spiral energy saving light bulbs there is mercury
Open the hood of the engine compartment. Locate the light bulb connector on the back of the headlight. Take hold of the light bulb connector, push in and turn at the same time. The light bulb will come out.
Light in fluorescent bulbs occurs when electricity excites the mercury vapor inside the tubular glass bulb.
Just unscrew the rear brake light, turn out the socket, and replace the bulb.
The bulb and the filament are the two main components of an incandescent light bulb.
Without the mercury in a CFL you wouldn't have light. The ballast in a CFL supplies initial current which excites the mercury which releases photons, or light. The mercury does not produce visible light, this happens only once the light passes through the phosphor coating on the inside of the bulb.
