We did it for decades focusing on this measure of electrical flow.
Does voltage matter for light bulbs.
Hose theory to understand this phenomenon an analogy is useful.
This is the default voltage for most lighting fixtures.
Choosing the correct voltage is crucial for the bulb operation.
This thin wire resists the flow of electrons.
When a bulb burns out most people simply grab whatever spare lightbulb is available.
You won t generally have much choice in the voltage as it ll be supplied by whatever voltage your system runs at.
The newer bulbs aren t marked in watts as the electrical ballast in them drastically alters what they run at.
And a 120 volt bulb wouldn t even light up with 12 volts applied to it.
The watts it will draw will be printed somewhere on the package.
We are used to buying bulbs taking into account their wattage.
There is potential danger here however because light fixtures carry a maximum wattage rating and if bulbs are installed that exceed this rating there is the potential for overheating the fixture.
You have to have a bulb that operates on the correct voltage.
For most cfl bulbs the actual power draw is about 25 percent of the equivalent incandescent bulb.
The filament of a light bulb is an extremely thin wire.
This is the default voltage for most lighting fixtures.
When it goes about light bulbs wattage determines its.
However as a trade off the bulb is also slightly dimmer and has a lower more yellow color temperature.
However if you can you.
You can calculate the resistance of the wire with the resistance equation.
Think of a garden hose.
For example a 12 volt malibu light bulb would immediately burn out if you applied 120 volts to it.
Watt is a basic unit.
Does wattage matter for light bulbs.
Almost all of them will have a printed description about the voltage and wattage of each particular bulb.
The wattage is how much power the bulb uses to operate and is basically an indication of how bright it will be.
However some lighting fixtures are low voltage.
It determines amount of mechanical thermal or electrical power.
Understanding voltage amps watts.
Does voltage matter for light bulbs.
If you look at a store display of light bulbs you ll see dozens of shapes sizes and colors.
The voltage is 120 volts and a 120 watt bulb has 1 amp flowing through it.
If the bulb isn t an incandescent bulb it won t draw 60 watts.
The 60 watt equivalent bright from the start cfl light bulb from ge for example uses exactly 15.
As a result the bulb burns cooler uses less energy watts and lasts longer.
Let s say you have a 120 watt light bulb plugged into a wall socket.
