No, it is not safe. The lamp is rated for a certain voltage, 125 volts, and supplying 240 volts to it would exceed design safety margins. It is not just a case of changing the bulb.
It would be a different story if the lamp itself were rated for 240 volts, but that's not what the question said.
The lamp will operate more brightly, but its life will be shorter. Because it is brighter, it must be operating at a higher temperature -so, provided that higher temperature doesn't harm the lamp holder or enclosure, then the answer is yes, you can.
If the plug fits you are good to go. The typical range of residential voltage is from 110 to 125 VAC. You are fine within this range.
Yes. The 125V is the rating of the bulb, which indicates the voltage it was manufactured to withstand. The voltage it is actually operated at does not have to be precisely 125V; As a matter of fact the voltage coming from your wall socket can vary from as low as 100VAC all the way to above 125 VAC. So, screw that bulb in and light up your world!
I saw a used one on eBay recently for $19.95.
Sure
The first thing we have to do is clarify the question. A cable rating of 125 volts is an insulation rating of the wire. Like wire with ratings of 300 volts, 600 volts and 1000 volts these are the highest allowable voltages that can be applied. A wire that is rated for 300 volts is good for 120 volts, 240 volts and 277 volts. At test research facilities, equipment is tested to destruction. The label that is given to wire as a result of the tests is the highest safest voltages that can be applied to that particular wire. So when you see a wire that has a label stating that it is rated for 300 volts it means that any voltage under and up to 300 volts is safe to apply. So to answer the question yes, the 125 volt insulation rating on the cable can be used to supply a source of 120 volts to a 120 volt rated piece of equipment.
Yes, the voltage listed on the bulb is the nominal voltage and it will work perfectly on a 120 volt circuit.
You tell yourself the 125 volt receptacle is a 120 volt receptacle. They're the same thing.
yes
NO! There are 50 bulbs in a 2.5 volt string or 125 volts. There are 35 bulbs in a 3.5 volt string or 122.5 volts. If you put 50 3.5 volt bulbs in you will have 175 volts and most american house have 110 volt service so you will have dim bulbs.
If the plug fits you are good to go. The typical range of residential voltage is from 110 to 125 VAC. You are fine within this range.
125% of 120= 125% * 120= 1.25 * 120= 150
-120
125 x 120 = 15,000
