florescent lamps have Mercury
the mercury plasma has three bright bands in uv to make the phosphors floresse
incandescent lamps have thorium allowed with tungsten so the tungsten doesent melt
LEDs have nice stuff like gallium and arsenic for particular jumps in atomic shells at the active layer
Neon lamps are sort of benign
Gaslights use methane but to be bright you add a mantle with thorium wire
perhaps a lime light is the answer
carbon arc is another benign light source

Why are compact fluorescent light bulbs bad?
Older CFBs contained mercury. However, today's bulbs contain little, if any, mercury. Buying today's bulbs is a good choice, as they produce the same amount of light as an incandescent bulb, but yet uses a fraction of the energy.
How do light bulbs cause global warming?
In a incandescent light bulb almost 90% of the energy taken in is being wasted as heat. only 10% is being used as visible light. this means that alot of energy taken in from ex sun,vind and water are not being used as it should have been. Thats why the LED bulbs are so good because they dont give out as much wasted energy
How are light bulbs hazardous?
Compact fluorescents, like their tubular fluorescent precursors, contain a small amount of mercury-typically around five milligrams. Mercury is essential to a fluorescent bulb's ability to emit light; no other element has proved as efficient.As effective as it is at enabling white light, however, mercury-sometimes called quicksilver-is also highly toxic. It is especially harmful to the brains of both fetuses and children. That's why officials have curtailed or banned its use in applications from thermometers to automotive and thermostat switches. (A single thermostat switch, still common in many homes, may contain 3,000 milligrams (0.1 ounce) of mercury, or as much as 600 compact fluorescents.)The problem comes when a bulb breaks. Mercury escapes as vapor that can be inhaled and as a fine powder that can settle into carpet and other textiles. At least one case of mercury poisoning has been linked to fluorescents: A 1987 article in Pediatricsdescribes a 23-month-old who suffered weight loss and severe rashes after a carton of eight-foot (2.4-meter) tubular bulbs broke in a play area.
Can light bulbs contain more than one filament?
Yes, automotive bulbs have more than one for turn and tail lights. 3 way bulbs in house lamps have 3.
Can you recycle xenon light bulbs?
Halogen light bulbs are a type of incandescent light bulbs and are filled with a halogen gas. The halogen gas gives the bulbs a longer life than traditional incandescent bulbs because it helps redeposit the evaporated tungsten back to the filament. Halogen light bulbs are not the same thing as compact fluorescent light bulbs (CFL bulbs), which have mercury inside and are often subject to state or local disposal regulations. Also, halogen light bulbs are not recyclable like CFL bulbs are.
Is mercury used for the filament in light bulbs?
No, not in the filament. You are probably thinking of compact fluorescent light bulbs, which do contain mercury.
Are flourescent light bulbs dangerous?
Compact Flourescent Light bulbs do contain mercury and can be dangerous if broken because of this.
How many atoms of mercury are in a light bulb?
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.
Are light bulbs that contain Mercury dangerous in any way?
yes they are dangerous because mercury will melt easily
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.
What should I do with incandescent light bulbs?
To dispose of incandescent light bulbs, you should wrap them in paper or plastic and place them in the trash. Do not recycle them as they contain small amounts of mercury.
Why are compact fluorescent light bulbs bad?
Older CFBs contained mercury. However, today's bulbs contain little, if any, mercury. Buying today's bulbs is a good choice, as they produce the same amount of light as an incandescent bulb, but yet uses a fraction of the energy.
What are the benefits of using LED light bulbs compared to fluorescent light bulbs?
LED light bulbs are more energy-efficient, longer-lasting, and environmentally friendly compared to fluorescent light bulbs. They also produce less heat and contain no harmful chemicals like mercury.
How do fluorescent bulbs glow?
Fluorescent bulbs contain mercury vapor that emits ultraviolet light when electricity excites it. The ultraviolet light then hits a phosphor coating inside the bulb, causing it to glow and produce visible light.
Do light bulbs contain gas?
Yes, some light bulbs contain gas, such as halogen or fluorescent bulbs, which help to produce light when electricity passes through them.
What gas is inside light bulbs?
Most incandescent light bulbs contain argon gas and a small amount of nitrogen. These gases help to prevent the filament from oxidizing and burning out too quickly. LED and fluorescent bulbs contain a mixture of gases like argon, xenon, and mercury vapor.
Do energy saver light bulbs contain mercury?
Yes, all fluorescent lights, including the compact fluorescents contain some amount of mercury. It is a necessary component to make the bulb work and is the reason fluorescent bulbs should not be broken for disposal, but should be sent through a disposal path that bring them to a responsible recycling and disposal organization. Compact fluorescent bulbs, also called energy saver light bulbs, have more mercury than the conventional long fluorescent bulbs, which have been developed in recent years to use less mercury than used to be the case.
