How much do normal incandescent light bulbs cost?
a single incandescent light bulb is around $1.49
Perhaps the greatest disadvantage is the issue of disposing of the fluorescent bulbs after they burn out. The fluorescent bulbs contain a small amount of mercury vapor so dumping them in a landfill will contaminate it with the mercury. Another disadvantage is the cost of the fluorescent bulbs compared to incandescent bulb (incandescent bulbs are cheaper because the materials to make them are cheaper). In most cases incandescent bulbs produce their full luminous power almost… Read More
For comparable lumens you pay less for energy efficient bulbs. For example, a typical 75 watt incandescent bulb provides about 850 lumens. The same light from an LED bulb would only consume about 12 watts. So even though the LED costs more to buy, it costs only about 16% of the cost of a comparable incandescent to operate. Read More
Xenon bulbs are much brighter than regular light bulbs. They are more expensive that normal light bulbs. this is partly because of the cost of xenon gas, but also because of the heat generated by the bulb that requires them to be housed in quartz instead of glass. Read More
Cost and aesthetics. Compact flourescent bulbs have an initial cost much higher than incandescent bulbs, though they are cheaper in the long run. CFLs also emit light that "looks" different than incandescent bulbs, and may not work for the desired application such as high intensity lights for work areas. Read More
Although they are larger than incandescent bulbs and cost more to produce, fluorescent lamps are more energy efficient and have a longer life. Read More

Fluorescent bulbs use less energy to produce a similar amount of light as incandescent bulbs. So they save money on power when used. But they cost more to make, and how the power consumed to make them compares I do not know. And they contain a significant amount of mercury, making them difficult to dispose of properly. There is much debate over which is better. Read More
It ranges on the watts and what store department you are getting it from. It is cheaper than incandescent. It will save you money and it will pay for itself. Read More
What do you think would happen to the energy bill at your school if all of the light bulbs were changed from incandescent to fluorescent bulbs?
The cost of lighting should drop because the fluorescent tubes use lower energy to obtain similar lumin Read More
Because instead of using a 40, 60, 75 or 100 watt bulb, you can get the same amount of light with using less electricity to run a fluorescent bulb. For example, if you are looking for the equivalent light output of a standard 100w incandescent, look for a 25w cfl (compact fluorescent light) Another basic way to understand this is that incandescent bulbs produce a lot of heat along with the light they emit. They… Read More
No they are cheaper compared to the other lightbulbs. However, if you want one that lasts and isn't going to cost as much I'd recommend buying LED lightbulbs. Read More
Incandescents tend to be less efficient and use more electricity. A lot of the energy used tends to be converted to heat, rather than light. Fluorescents tend to give you more light for the buck! They run less hot, which tends to mean that more energy is being converted to light, rather than heat. Compact fluorescent bulbs (CFBs) are a good alternative to incandescent bulbs. They have the same type of sockets, so no rewiring… Read More
To answer this question more data is needed. Total wattage of the 5 incandescent bulbs, length of time the bulbs are on in a 24 hour period and what you are charged per kWh in your area from the utility company. Read More
Florescent light bulbs produce a similar amount of light with much less power than incandescent light bulbs. Their initial cost is paid back in energy savings. They also last a lot longer. I exchanged every light in my house for florescent bulbs years ago and I haven't changed more than 4 or 5 in all that time. LED bulbs are now on the market and are very expensive. But they use even less power to… Read More
Take a look here, this explains all the types of light bulbs. Incandescent: A majority of American households use incandescent light bulbs in their home. These bulbs are inexpensive and produce a warm light that is suitable for basic household- or appliance-use. The average incandescent bulb lasts around 1,000 hours. Halogen: Halogen bulbs are similar to incandescent bulbs, though they are more energy-efficient and last longer. Halogen bulbs produce a bright white light. They become… Read More
A few months. You'll have to do the calculations by yourself, for your case - both the cost of light bulbs and the cost of electricity may vary depending on the region. Assume that the low-energy light bulbs use about half, or one third, of the old-style incandescente light bulbs. Read More
The incandescent light bulb is not efficient. Incandescent light bulbs have been around for about 200 years. They produce an appealing warm yellowish light. Their small compact design makes them easy to install in even small table or bedside lamps. Until 30 years ago they were the only electric bulbs available for household lighting. Their biggest downside is that they are inefficient to operate in that they use a relatively large amount of electric power… Read More
LED lighting is more cost efficient in the long run, although the initial cost may be higher. Light Emitting Diodes use less power than conventional bulbs, and even fluorescent bulbs. Read More
Compact fluorescent lamps or CFL grow light bulbs can be used for growing indoor plants. A CFL grow light is of great help to growing plants because it provides the color spectrum which a plant needs to flourish. Using CFL grow light bulbs, however, has its pros and cons. Advantages of CFL Grow Light Bulbs: CFL grow light bulbs are cost efficient. These bulbs are cheap and easy to find. A 60-watt bulb only costs… Read More
There are two main types of commercially available energy-efficient light bulbs. These are LEDs and CFLs. Both are better than traditional incandescent light bulbs when it comes to energy efficiency The efficiency of light bulbs is calculated by comparing the amount of light produced to the amount of energy consumed: LED bulbs produce 90 to 112 lumens per watt. Compact fluorescent lamps or CFLs produce 40 to 70 lumens per watt. Traditional incandescent bulb fixtures… Read More
Glass was, and still is, a cost effective means of insulating the burning filiment of a light bulb from the air. It is also important that it is transparent so the light is not blocked. This greatly slows the burn rate allowing the bulb to last longer. And it protects people from burning themselves on the filiment. Read More
About how much money does a consumer save over three years by using a fluorescent bulb in place of an incandescent bulb?
The latest comparisons for energy efficiency and energy costs based on a 1200 hour incandescent lamp at 60 watts are;Light Emitting Diodes (LED) - 329 kWh/year at an operating cost of $32.85 per year. Incandescent Light Bulbs - 3285 kWh/year at an operating cost of $328.59 per year. Compact Fluorescents (CFLs) - 767 kWh/year at an operating cost of $76.65 per year. Read More
The estimated cost of late 1800's first generation light bults is about $8,000 dollars Read More
LED (Light Emitting Diode) flashlights tend to last longer and they do not omit the yellowish coloring that an incandescent flashlight does. LED flashlights will also be lighter in weight compared to incandescent flashlights. Although the cost of LED flashlights can be a bit higher than a conventional flashlight, one would find it worth the extra cost due to it's higher energy efficiency and longer lasting life. Read More
What is the price difference between a normal light bulb and an energy efficient one of the same power?
The energy efficient light bulb costs several times as much as the normal (incandescent) light bulb. The exact prices may vary from region to region. In any case, the extra cost will be more than compensated by savings in electrical energy, over the lifetime of the bulb. Read More

The lightbulb that is best for cost saving is an LED bulb. These bulbs often cost in upwards of $20 or more, but they will consume much less energy than CFL bulbs and will create much less heat. They will also last much longer than regular bulbs. Read More
If only 3 of your 5 chandelier light bulbs are lit what is happening to the sockets with the 2 burnt out light bulbs?
well, nothing. the electricity is just sitting there in the filament holder of the bulb going nowhere, no current no light. no cost either for that matter... Read More
Long answer: it depends what kind of bulbs you're using, how big your plant is, how you have the light spaced, etc. 250 watts= 5, 50 watt incandescent bulbs; 6, 40 watt, 4-foot fluorescent bulbs; two 125 watt metal halide or high pressure sodium bulbs. If you can afford the HPNa or the MH, you can afford more wattage. If you're strictly limited, I would recommend 3, 4-foot, dual bulb fluorescent shoplights with alternating "daylight"… Read More
That depends on the type of bulbs you replace, the type of replacement light bulb, how long you typically use a light bulb, and what the cost of electricity is in your country. Here is a sample calculation: Previously we normally used 100 Watt incandescent light bulbs. A 40 Watt fluorescent light bulb shines about as bright. That's a saving of 60 Watts or 0.06 kilowatts, equivalent to 0.06 kWh/hour. If we use the light… Read More
The first commercially available light bulb cost $1 in 1881, which was three years after Thomas Edison developed the first practical incandescent light bulb. The Seattle Times reveals the $1 price in 1881 translates to $23 in 2013. By 1910, the cost of a light bulb dropped to 17 cents. Read More

The invention called a light bulb is a round item that gives out light when it is supplied with the right kind of electricity. It was first invented and patented by Thomas Edison and is used world wide. A light bulb lights a room by just a single switch! Electrical current flows through a filament which resists the flow of electricity. This causes the filament to get hot and glow. The filament doesn't burn up… Read More
A fluorescent lamp or fluorescent tube is a gas-discharge lamp that uses electricity to excite mercury vapor. The excited mercury atoms produce short-wave ultraviolet light that then causes a phosphor to fluoresce, producing visible light. A fluorescent lamp converts electrical power into useful light more efficiently than an incandescent lamp. Lower energy cost typically offsets the higher initial cost of the lamp. The lamp fixture is more costly because it requires a ballast to regulate… Read More
It is stated that gu10 light bulbs use less than 10 percent of what a normal halogen light bulb does. This is a great difference. They save a huge chunk of your energy bill and return save you a lot of money. Although they do cost quite alot more than the normal gu10 bulb you have to remember that they last around 20,000 hours. You can calculate how much they are going to save you… Read More
Typical old fashioned traffic lights use incandescent bulbs and also generate some heat. Therefore, in colder climates the lights themselves helped keep the lights free of ice and snow. Light Emitting Diodes (LED) have now replaced the bulbs in many traffic lights because although they cost more, LED's last longer and use less power. However, they can be a problem in colder climates as noted. Read More
The manufacturers of light bulbs want to give their customers light. This requires the use of energy (Watts) which cost money for their use. Manufacturers design their light sources so that users get as much light as possible from the bulb for a given wattage while maintaining a reasonable lifetime (otherwise we would just get flash bulbs). Read More
The first types of light bulbs invented by Thomas Edison were sold for about one dollar. That is the equivalent of about 23 dollars today. Read More
The answer is that they are not necessarily the same. LED lights can be Christmas Lights, but not all Christmas Lights are LED Christmas Lights. LED or Light Emitting Diodes are the type of light source used not a general type of light. LED lights can be used for Street Lights, Flood Lights, Rope Lights, standard household lights or Christmas Lights. Just about any light out there now comes in an LED version. Using LED… Read More
What does it cost to buy and use one 25-w compact fluorescent bulb compared with number of incandescent bulbs for 10000 h of light?
The CF bulb costs let's say £3 and lasts 8000 hours during which time it will use up 8000 x 25 watt-hours of energy, that is 200,000 watt-hours or 200 units, costing 200 x £0.15 which is £30. An incandescent bulb would have to be 100 watts for the same light, i t might cost 60p but its life is only 1000 hours so you would need 8 to last 8000 hours, costing £4.80. The… Read More
