Are mercury vapor light bulbs which cycle on and off through out the night energy efficient vs fluorescent flood lights mounted on a motion detecting fixture?

First, if your Mercury vapor lights are cycling on and off you probably have a bad ballast. Any ballasted bulb will be much less efficient when cycling on and off. The greatest amount of power is used when the power is first transmitted through the gas within the bulb. Second, Florescent bulbs are just about as efficient as mercury vapor lumen for lumen. Hope this helps Terry

What gases are used in fluorescent light bulbs?
Fluorescent lamps (both the "compact" variety and the long tubes) are filled with inert gas (argon, xenon, neon or krypton) and mercury vapor, under low pressure (less than 1% of atmospheric pressure)Neon. and lead
What kind of light does fluorescent light produce?
Main one is light energy. Also some heat is produced
Is a fluorescent bulb is filled with gas at a high pressure?
No, just an inert gas and mercury vapor at close to atmospheric pressure. Without the inert gas it would be near vacuum, as very little mercury is needed.
Are fluorescent bulb fragments dangerous if stuck in your skin?
You mean, as distinct from the normal, perfectly safetype of having glass fragments stuck in your skin?The big danger with fluorescent bulbs is usually the mercury vapor contained within, and secondarily the phosphors which are made of Lord knows what.
Do light bulbs contain mercury?
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
What is a similarity in the line spectrum of mercury and the spectrum of the fluorescent bulb?
A fluorescent lamp contain mercury so the identities of spectrum are normal.
Is Mercury contained in a fluorescent light?
Yes. Argon and mercury are present.
How does a fluorescent light fitting operate?
mercury
Will mercury vapour work in a sodium vapour fixture?
no
What is inside a fluorescent lamp that is toxic to humans?
Mercury
What is mercury used for in fluorescent lights?
Jo tromans
Do compact fluorescent lamps contain mercury?
yes
What element is found in fluorescent light fixtures?
Mercury
What element is in fluorescent light tubes?
mercury vapor
Which substance is present in fluorescent tube?
Mercury and Phosphorous.
Myths and Facts About Fluorescent Lights?
Fluorescent lights are an excellent choice for home, office, and school environments because they offer many benefits. Still, some myths persist that cause consumers to question the use of fluorescent bulbs. Here are the facts about this type of lighting. Myth: Fluorescent lights flicker, causing eye strain and even headaches. Fact: It used to be true that fluorescent lights had an annoying flicker, accompanied by a slight buzzing noise. Improved technology has eliminated these drawbacks. New fluorescent bulbs use an electronic ballast that produces a steady, silent light. Myth: Fluorescents are more energy-efficient than incandescent bulbs, but less efficient than halogen lighting. Fact: Compact fluorescent lights are almost three times more efficient than halogen bulbs (and more than ten times as efficient as incandescent bulbs). Moreover, fluorescent lighting doesn't consume any power when it is switched off. Halogen bulbs, in contrast, utilize transformers that can continue to consume power even when the light is turned off. Myth: Fluorescents are bad for the environment because they contain mercury. Fact: Fluorescent bulbs do contain a small bit of mercury, which means that they must be discarded in a responsible manner. However, not using fluorescent lights will result in even more mercury being released into the environment. This is because other forms of lighting consume more electricity, which is generated at this time mostly through the burning of fossil fuels. This produces power plant emissions containing mercury. The best way to reduce mercury in the environment is to burn fewer fossil fuels by using fluorescent lighting wherever possible. Myth: Fluorescent light bulbs won't fit inside certain light fixtures, such as the ceiling globes used in many factory-built homes. Fact: Again, this used to be the case, but the advent of the compact fluorescent light bulb changed everything. Today's fluorescent bulbs are smaller than a standard incandescent bulb and will fit in any lighting fixture designed for incandescent bulbs. Myth: You can't use fluorescent bulbs with dimmer switches. Fact: You can use dimmer switches that have set levels such as bright, brighter, and brightest -- as long as they are wired for fluorescent bulbs. However, continuous dimmer switches are still not used with fluorescents.
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.
