The standard bulb is 120v.
130v light bulb in 120v socket.
That bulb at that firehouse is likely at a much reduced voltage.
Newer post older post home.
A 130v verses a 120v bulb.
Voltage is the amount of voltage the bulb can handle when the electricity comes into your home.
120v vs 130v light bulbs recessed light bulbs replacing recessed lighting light bulbs.
Now 130 volt bulbs are taking over.
With a 60 watt light bulb for example you are forcing 0 5 amp of electrical current the water through the filament the hose with 120 volts of pressure.
A 130v bulb is a commercial grade that will last longer because it will not be operating under full load hence the bulb should last longer.
At one time there were only 120 volt bulbs.
This is indicated in either 120v or 130v.
The life of a bulb is roughly the ratio of rated volts operating volts to the 6th power.
The current meets the resistance of the filament causing the filament to become hot and glow.
A 130v light bulb has a heavier duty filament in it than a 120v bulb does so the bulb will last longer.
If you have put a 120v light bulb in a table lamp and you ve blown a couple pretty quickly you most likely need a 130v light bulb.
The 130v bulbs will consume less than rated watts and produce even less lumens than the ratio of reduced wattage would indicate.
You can use a 130v light bulb where a 120v bulb is indicated but you will not achieve.
