More voltage than required will light something such as a bulb.
However, you have to consider such things as bulb longevity. Anything over 12 volts will illuminate a 12 volt bulb. If it's connected to an engine alternator and not a pure clean 12 volt power supply, ideally 13.5-14 volts is the voltage you're looking for to power this bulb.
16 volts will work, but it may prematurely burn the bulb out.
That is, unless it is an LED. Even overpowered they will continue to burn bright, but not burn out, but it won't last as long as if it were connected to a true 12 volt supply voltage. But in the end, even an overpowered LED will last longer than an overpowered 12V incandescent bulb.
It will definitely burn out prematurely if a higher than design intent voltage is supplied, however the hours. minutes, seconds lost may not be as high as people may assume them to be, from 12v to 16v is not such a jump especially in light of most automotive applications having output voltages up to 14.8v a car battery typically has 6 x 2.2v cells making 13.2v

A 12 volt incandescent bulb can be used with a 6 volt battery, but the lumen output will be slightly less than half. Better to use a 6 volt bulb or two 6 volt batteries in series.
Wiki User
∙ 13y agoIt is not recommended to operate a 6 volt bulb on a 120 volt supply as it will burn open instantaneously.
Wiki User
∙ 13y agoTechnically, yes... brightly and briefly.
Putting 12 volts through a 6 volt bulb will generally burn it out extremely quickly, rather like a flash bulb.

Wiki User
∙ 8y agoYes, but the life time of the bulb will be shortened due to the extra heat generated by the bulb at the higher voltage

How many 290 lumen 7 watt light bulb is needed to power a 5 watt 12 volt solar panel?
None, since one does not normally "power" a solar panel. However a single 7w lamp would be useable with a 5watt panel but with reduced efficiency unless the panel was used to charge a battery first and then the bulb was powered by the battery.
Can you use a 120 volt - 500 watt bulb in a 220 volt lamp?
no , it will burn out
The problems of electricity two light bulbs of 100 watt and one 60 watt both operation in a 220V circuit. Which bulb has the higher resistance and which bulb carries the greater current?
A 100 watt 220 volt light bulb (or anything consuming 100 watts on 220 volts) draws 100/220, or .45 Amps. It will also have about 220²/100, or 484 ohms resistance. A 60 watt 220 volt light bulb (or anything consuming 60 watts on 220 volts) draws 60/220, or .27 Amps. It will also have about 220²/60, or 807 ohms resistance.
What is 60w light bulb?
a normal incandescent 60 watt light bulb uses 60 watts of electricity to produce 20 watts worth of light, and 40 watts worth of heat. It is more of a heat bulb than a light bulb. it is great if you can capitalise on the free heat, but if it is not cold in your house, turn it off. is there a better bulb? no. why are they ideal? cheap (as low as 10 cents for the el cheapos), never change shape/design/size/compatability, make pleasant light I could go on for an hour, but the best bulb is the cheapest.
Why does the current in an electric circuit decrease when more bulbs are added?
If you add one extra bulb and the voltage remains constant, then you have doubled the current drained from the regulator. 12 Volt and One 12 Watt light bulb drains 1 Ampere Current. 12 Volt and Two 12 Watt light bulbs drains 2 Ampere Current. However: If having a 24 volt power source and you add two 12 Volt 12 Watt in serial, then you still only drain 1 Ampere Current. NOTE: Wattage and Voltage of bulbs may be different even if the sockets are the same. Lower voltage on the bulb will increase the current drain, if voltage is a lot lower it might cause the circuit delivering voltage to burn out or blow a fuse. It can also quickly burn the bulb, sometimes in a fraction of a second. It will however do little damage to add a bulb with higher voltage than the circuit is designed for. You will then only observe that you do not get the light you might hope for. Total Current/Ampere= Combined Wattage divided by Voltage Total Wattage = Combined Current or Ampere multiplied by Voltage. In simpler words: If you double the bulbs, twice the current is drained from the battery
Can a car battery light up a 60 watt regular light bulb with out using a power inverter?
Yes it it is a 12 volt DC light bulb. It will not operate a household 120 volt light bulb.
Is 12 volt is enough for a 100 watt light bulb?
12 volts is enough for a 12-volt 100-watt light bulb. It would not be enough for a 120-volt or 240-volt bulb.
What kind of battery can power a 40 watt light bulb?
If the bulb is a 40 watt, 120v bulb, you would need 20 6 volt batteries wired in series, or 80 (!) 1.5 volt batteries. 1.5 volt batteries are AAA, AA, C, D, etc. Since this solution is rather extravagant, try finding a light bulb made for an RV. These typically run off of 12 volts, and you can get a single 12 volt battery, or 2 6 volt batteries, to run this bulb.
What size light bulb is in a deep freezer?
Mine has a 25 watt 120 volt bulb in it.
Can you use 220 volt light bulb on 120 volt system - I know the reverse would probably blow the bulb so wouldn't European 220 Volt do ok in 120 volt socket or would it be dimmer than it normally would?
Yes a 220 volt light bulb will run on a 120 volt circuit but at 1/4 of the wattage that the light bulb is rated at. A 100 watt light bulb on 220 would would be equal to a 25 watt light bult on 120 volt system.
WILL 103 VOLTS LIGHT A 60 WATT LIGHT BULB?
Yes, a 103 volt source will light a 60 watt light bulb. The relationship of the bulb's wattage output at a lower voltage, as to the normal voltage that the bulb is rated to operate on, the light output will be lower.
Can an 18 watt bulb be used in low voltage outdoor lighting?
If it is an 18 watt 12 volt bulb, then yes. But an 18 watt 120 volt bulb - then no.
It is night and you turn on a flashlight The energy in the battery is transformed into heat and light in the bulb If the battery produces energy at a rate of 0.80 Watt and 0.04 Watt leave as light?
.76 watt
What is the common bulb number for a 12 volt 18 watt automotive backup light?
1156
Can you use a 130 volt 60 watt bulb in a socket that was made for a 110 volt 60 watt bulb?
yes the bulb will actually last longer
How long can a battery power a 44 watt light bulb?
To answer this question the amp hour rating of the battery is needed along with the voltage of the battery or bulb.
How do you wire a high watt light to a battery?
Need more information. Wattage of bulb, voltage of bulb, voltage of battery and wire size of the circuit.
