What light bulb to use for 250W/250V socket?
250W/250V is the maximum rating on the socket. The more important question is first what is the standard voltage in your country? Next is what base is the socket? A "standard" base is also known as "Medium" base. If the socket is larger than "standard", then it is most likely a Mogul base. So you can put any light bulb into your socket that will fit its base up to the listed rating. The rating on a socket is based on the heat that it can withstand which is generated by the wattage of the bulb. You can put a 100 watt 120 volt bulb in there if your local power is 120 volts. 100 watts might be too bright, but you can put something smaller if you wish. Mogul base bulbs use to be available at well supplied hardware stores, but you would have to get them online these days if your lamp has a Mogul base. Most Mogul bases used today are high pressure vapor bulbs (aka "lamps"), but Mogul based incandescent bulbs can still be found. Without more description from you this is about as far as I can go to help you. Is it a 3-way? You can tell by looking into the socket. If it only has one contact in the center of the socket, then it is a single. but if it has two connectors within the center, then it is a 3-way bulb.
75 Watt Light Bulb in a 40 Watt Socket? Can i?
120Volt is the key word here not 40 wattor 70watt. you dont need different sockets for different bulbs! " 2 thumbs down?Even if I wasnt an apprentice electrician this is an easy one.All that'll happen is you pay an extra 2 dollars on your bill but you get better light in return. They dont "blow up" "ruin your electricity" or "go on fire". Geez!
Can I lubricate a light bulb to make it go in easier?
YES you can but be careful it has to be a electrical lube the sell this at moust electrical supply stored do NOT use WD-40 or greese it will burn if ever arck or gets to got.
Can I put 110v light bulbs into a 250v Socket?
Sockets are often marked with the voltage rating of the socket. That is the maximum voltage it can withstand without breaking down and arcing. They are designed to 250V to work with margin in 120V and 230/240 volt useage; they can be used with either of them. Neither one would exceed the rated voltage.Sockets really have no way of determining what voltage is wired to the socket and changing the writing on the socket to indicate so.So if it says 250V it will work OK at 120 or 240 (US standard voltages).Now you can literally put any bulb you like into the socket, that will fit, but you won’t like or enjoy the results unless the voltage of the bulb matches the voltage that is wired to the light fixture.I suggest you confirm by checking with a voltmeter or by checking with an electrician that the chandelier is wired for 120V and then you can use 120V bulbs.In the US, most all residential lighting is going to be 120V.
What light bulb can I use if a socket says ���40 watt only”, and I need more light?
LED bulbs. The light production is so much more efficient that a 25 watt LED produces the same luminosity as 1 150 watt incandescent, it will also last 20 or more times as long, while producing more light and less fire hazard. Even a CFC bulb will do better with a 20 watt bulb out producing a 70 watt incandescent, but only lasting about 10 times as long. I wouldn’t by a CFC, but if you already own one, it will be an improvement.
When there is no light bulb in the the socket but the light switch is on, is electricity being used?
For current to flow in a circuit the circuit must be closed. If there is no light bulb in the socket the current cannot flow across this gap in the circuit, therefore no electricity is being used.If the circuit is designed such that the light socket is in parallel to the power supply then there may be another node for the electricity to flow through, however as there is no "load" then you have a short circuit. This means that the electricity flows from the source, around the wires, and back to the source. This isn't good! You may end up with melted wires or the power source blowing up. When there is no resistance to the flow of charge carriers you get a very high current, a large amount of energy is transferred in a very short amount of time. This large amount of energy needs to go somewhere, either back to the source or transformed in the wires as heat energy. In your home you will find a circuit breaker. This provides protection in the event of high current flow, and will break the circuit and stop the flow of current.Alternatively you may find if you are using a lamp with a plug, the plug may be fused (depending on the country you live in), this fuse in the plug has a small piece of wire inside that is rated for a certain amount of current. If there is a short circuit and the current goes above the rated limit, then the wire inside the fuse melts - stopping the flow of current.
Question about light bulbs, sockets and plugs
the only thing that i can tell you for sure is; yes, you will have to stay with a 110 volt bulb. that said, try your yellow pages for a lighting supply store and check with them as to your options for lower wattage and color choices. i've come accross a few odd bulbs myself lately, and my local lighting store person even can tell me what the bulb was originally designed for, (most of the time, it's not what it's being used for in my case!). they may even have some sort of "shade" or surround that would be a better way to "change" the color of the bulb, instead of painting it. i hope the people at the lighting store near you are as helpful as the ones near me. if you don't have any luck with them, email me and i'll give you the name of the people i use and you can contact them. good luck, car dude.
How can I light up a light bulb without a socket?
One of the purposes of a socket is to protect anyone near the light bulb from touching a live wire. If you are using line voltage (120 or 240V) you would have a real hazard from going near that socketless lamp. The older style bulbs had brass sockets that you could solder wires to but nowadays they use aluminum that you can not solder wires to. So there goes that attachment opportunity. You could try taping the wires onto the screw part of the lamp base and the center portion of the lamp base and then cover the whole mess with some more insulating tape. If you really want to do something like that you could use a low voltage lamp (like 12V ones from a car). Some of them come with wires instead of a socket. They would be easier and safer to handle.
What happens if a light-bulb in the socket is of a lower wattage (or higher wattage) than the one the socket specifies for?
The socket does not specify a wattage. The watt rating on a socket is the maximum wattage (based on using an incandescent bulb) that can be used without overheating and potentially causing damage or even a fire.So a socket rated at 60W may have a 60W or lower incandescent bulb in it. However, this is rated at the actual power, not equivalent light. So you might get away with putting a CFL or LED bulb in that is higher than 60W equivalent in light output, as long as the actual power is 60W or less.However, this is important: Many CFLs and LED bulbs are not meant to be used this way. The base gets hot, the electronics get hot, and heat is the enemy of electronics. So if a light fixture or socket is rated at 60W max incandescent. I would stick with CFLs and LEDs with equivalent light output of a 60W incandescent.Read the box - many CFLs and LED bulbs are NOT rated to go into enclosed fixtures like recessed ceiling lighting, or they may overheat. Most of the first run of CFL bulbs weren’t even supposed to be used upside down!
Can I use a 60W LED lightbulb in a 40W lamp?
If you asked the UL listing board of regulators they would most likely say no as the guidelines are strict and they would say use what it says it's rated for. That being said, the ratings usually are rated this way due to heat. If you use a plastic socket and a traditional bulb larger than 60w the chance for heat to be created and melt the socket causing fire was very real. The LED bulbs are rated a bit differently. It says 60w but uses 11w of power to generate the brightness of what an 60w bulb would create. The heat created should not be enough to heat up the socket. I would say yes, it is OK to replace the 40w bulb with a 60w bulb using only 11w.The thing to do it try it and turn it on while you are home and monitor it. Let it burn for a couple hours and check it out every 10 minutes to see if it is smoking or the socket is heating up. If there is no heat you should be fine. Again, as a general rule, go with what the sockets say they are rated for to ensure safety and not cause any electrical fires.
