What is the name for a regular light bulb?
incandescent
Does a yellow bug light put off the same amount of heat as regular incandescent light bulb of the same wattage?
YES
Do incandescent light bulbs have more mercury in them than fluorescent?
I would say no. My reasoning is that if incandescent bulbs have as much or more mercury than fluorescent bulbs, the fluorescent industry would be debunking all the reports of a mercury problem.Incandescent lights do not need or use mercury to operate, so there is none in them.Fluorescent lights cannot be made at all without mercury, as it is the glow of mercury ions that produces the UV light inside the fluorescent bulb to excite the phosphor coating to make visible light.
Which bulb lasts longer an incandescent light bulb or a compact fluorescent light bulb?
A regular incandescent bulb uses a lot more energy than a compact fluorescent to produce the same amount of light. Most energy used by an incandescent bulb is wasted as heat which does not give off visible light. Incandescent bulbs are cheaper to buy, but they have shorter lifetimes than other alternatives.
Why is is a compact fluorescent light bulb more efficient than a incandescent bulb?
A compact fluorescent lamp (CFL) uses electrical current to vaporize a small amount of Mercury, that in turn, excites a phosphorous coating on the inside of its tubing. This process allows almost 75% of the energy consumption to be converted to visible light. In contrast, an incandescent lamp passes current through a resistive filament that heats to the point of emitting light. This process spends almost 90% of the energy consumed producing heat, with the remainder left over for it's intended purpose.
What is the name for a regular light bulb?
incandescent
What gases are in a incandescent light bulb?
None, the inside is a vacuum.
Why bulbs contains phosphor inside the glass?
In an incandescent bulb, if there is no phosphor coating the glass, the filament produces a very glaring light that is painful to look at directly. The phosphor takes the light of the filament and turns it into a more even, and less glaring glow.
Are the lights people use today incandescent lights?
Yes, anytime your see a glowing wire inside the light it is an incandescent lightbulb
How do CFLs work?
A compact fluorescent lamp rather than producing light by creating heat (i.e. like an incandescent light source), produces light by exciting mercury vapor inside the bulb's glass envelope. The initial excitation of gas is not enough to produce visible light (at this point it is actually UV light), the light produced is only visible once it passes through the phosphor coating on the inside of the bulb.
Which type of light bulb glows when a filament inside it gets hot?
An incandescent bulb.
Does a yellow bug light put off the same amount of heat as regular incandescent light bulb of the same wattage?
YES
What is incandescent light bulb?
An incandescent light bulb, incandescent lamp or incandescent light globe is an electric light which produces light with a wire filament heated to a high temperature by an electric current passing through it, until it glows.
What is the difference between floroscent and incandescent?
Incandescent light bulbs contain a metal filament (normally tungsten). When electricity flows through the filament, it gets very hot, causing it to emit light. They are inefficient because most of the electric power goes into heat. Fluorescent light bulbs contain a circuit that increases the voltage of the electricity, which then ionizes mercury vapor. This ionized mercury emits ultraviolet light, which causes a coating on the inside of the glass bulb to glow ("fluoresce). They are more efficient, but many emit an ugly color of light.
What kind of waves do heat lamps give off?
A little more heat and a little less light than a regular incandescent light bulb.
How do you produce light bulbs in CO2?
You do not. CO2 has nothing to do with the creation of a light bulb. A typical incandescent bulb has a vacuum inside. No light bulb uses CO2.
What kind of EM wave do heat lamps give off?
A little more heat and a little less light than a regular incandescent light bulb.
