What is the risk of using a 100 watt light bulb in fixtures that are rated for 75 watt bulbs only?

All light bulbs are safe to use. They have under gone underwriters safety tests before that can be sold by the manufacturer on the open market. The reason that people use different size lamps is because of the difference in costs of operating the lamp. Remember the higher the wattage the higher you will pay for operational costs. Using a smaller lamp in a specifically rated fixture will cut down on the amount of heat that the fixture will have to undertake, but there again the fixture has been certified for the amount of wattage that is shown on the fixture's label on the amount of wattage that the fixture can handle. With that out of the way using a 40 watt light bulb in a 60 watt rated light fixture is safer than using a 100 watt light bulb in a 60 watt rated light fixture.
Using a 100 bulb in a fixture rated for 60 watts is dangerous. A 100 watt light bulb gets hot enough to deform or melt some of the components of the lamp socket and may cause a fire. It may be difficult to remove from some plastic sockets after it has been heated up and melted to the base of the bulb.
A fixture rated for 100 watts usually has a ceramic socket.

∙ 10y agoWhen a light fixture is rated for 60 watts, it means this is the maximum power its bulb socket and cover or lampshade can safely handle.
It is OK to use a lower rated bulb but not a higher rated one.
A 100 watt incandescent bulb used in a socket rated for only 60 watts will seriously overheat the socket: it is highly likely that the plastic components in it will discolor, deform and/or melt and the excessive heat could easily cause a home fire.
Sockets rated for 100 watt incandescent bulbs are usually made of ceramic materials and not plastic.
If the bulb is a low energy CFL (compact fluorescent lamp) the actual power used by the CFL itself should be used in deciding whether it can be used or not. (Don't use the wattage of the incandescent bulb that is equivalent to it to give the same light output.) So a 20W CFL bulb can be used in a 60W fitting even though it is equivalent to a 100W incandescent bulb, but you must always ensure that the CFL bulb will actually fit safely into the cover or lampshade without any physical stress to them - or to the bulb or the socket - and you must decide whether or not the CFL looks ugly in that particular light fitting compared to using a normal incandescent bulb! but CFL bulbs don't normally look ugly and they save energy, you pay less and the environment suffers less as well!

∙ 12y agoThere is quite a risk if a lighting fixture is only rated for 75 watts then that is the maximum wattage that should be applied to the fixture. The manufacturer of the fixture has to get an inspection on the electrical device that he wants to sell. This is done through an underwriters that determine what the maximums the device will take by testing it until it destroys itself. With a lamp, different size bulbs will be installed and the results noted as to which wattage damaged the fixture. Bottom line when the lamp label states the bulb size adhere to that bulb.

∙ 12y agoPossibly could catch fire.At least ruin the lamp by it melting.Just use a florescent.

∙ 11y agoIf the lamp is rated for the maximum bulb wattage, usually 150 watts, and there is a switch and base that accommodate the bulb you should be okay.

Can outdoor light fixtures be installed inside?
Yes. The difference between fixtures rated for indoor and outdoor use is their level of protection from outside elements, i.e. moisture. Using an indoor rated fixture outdoors would result in an early failure due to water intrusion into the fixture. Using an outdoor fixture indoors should work fine. Also, because of the more robust nature of fixtures rated for outdoor service, they are usually more expensive.
Does the shape of a light bulb matter?
It most certainly does. For one, there is the matter of aesthetics. Different shapes are used for different decorative applications. Round ("G" for globular) are often used in light fixtures in baths and dressing rooms as opposed to the most common "PS" or "pear shaped" light bulbs. Some light fixtures and portable lamps will only accept "T" (tubular) light bulbs such as picture and piano lamps. Certain shapes are determined by the electrical characteristics of the light bulb. Fluorescent light bulbs are tubular as a result although the tube may be wrapped or formed into different overall shapes, it is still a tube. Compact fluorescent light bulbs are simply fluorescent tubes that have been folded or wrapped into a compact shape. Light bulbs using reflectors have to be of a certain shape in order to properly reflect light in a certain direction and pattern.
What is 130V brass base light bulb used for?
There are not many brass base bulbs left in service these days. This is because aluminium is a cheaper product to use. The 130 volt rating is the maximum voltage that can be applied to the filament. Using this rated bulb on 120 volts will extend the lifetime of the bulb. Many traffic signal fixtures used 130 volt bulbs to cut down on maintenance of changing burnt out bulbs. Today most traffic light have been changed out to LED lamps that get about five times the life of the old incandescent bulbs.
Can a 250 watt heat bulb go into any lamp?
no the fixture has to be rated for the size and type of the bulb. most fixtures are not rated for 250W
Why fluorescent lamps not used on streets?
In colder climates a special ballast and lamps have to be used. These are known as cold start ballasts. The cost is much greater using fluorescent fixtures than HID fixtures and the light output is much less.
Using Outdoor Light Fixtures to Accentuate your Garden?
Creative light fixtures can be used indoors or outdoors to highlight particular features of a room or garden, to create a mood of your choosing, or to brighten an area used for entertaining. Try small and bright light fixtures along a stone garden path to draw the eye towards the center of your garden. Or, for a creative touch, try using colored light fixtures or bulbs in or around an outdoor fountain. Casting colorful light on the water in your fountain will give your garden an enchanted look that will be memorable to visitors.
What are some advantages of using GU10 light bulbs?
Some advantages of using GU10 light bulbs are the fact that you could avoid the disadvantages of using regular light bulbs. GU10 light bulbs don't have poisonous gas inside of the bulb.
When did light bulbs start using watts?
Light bulbs have always used watts.
What is the difference between fluorescent bulbs and regular light bulbs?
Fluorescent bulbs generate light by using an ionized gas and electrical discharge, whereas regular light bulbs generate light by using heat within the filament contained in the bulb.

How do you know how many light fixtures a 15-amp 120-volt circuit can hold?
Depends on the fixture rating which is sized by the bulb wattage. For example, if you were using 60 Watt incandescent bulbs, they draw about 1/2 amp each. For a worst case continuous load that would be 80% of 15 amps = 12 Amps so it would be 24 fixtures rated for 60 watts each.

Why where light bulbs invented?
To produce light using electricity instead of using fire.
Change the Light Bulbs!?
Still using incandescent light bulbs? If so, you're wasting electricity and your electric bill will no doubt show it. Fluorescent lighting is far from new, but the way the bulbs are shaped, is. There was a time when you couldn't buy a fluorescent light bulb to fit many existing lamps and fixtures. Someone must have heard us complain, because now you can find fluorescent bulbs in almost any shape and size. A simple and effective way to watch your electric bill go down measurably is to simply change light bulbs from incandescent to fluorescent.
Where is the socket on a track light?
Probably still at the store. Track light hardware is sold as individual components; the track is separate from the light fixtures. Find a distributor of the BRAND/style of track lighting that you're using, then purchase the light fixtures that you want to use.
What are the benefits of using light-bulbs?
i think it can help to things clearly.
