The higher the rated wattage of the bulb, the greater the luminous efficacy, which means you get more lumens per watt using a 120-watt bulb than using two 60-watt bulbs.
Check the lumen ratings for the two 60 watt bulbs, and compare it with the lumen rating for the 120 watt bulb. That should give you the answer you seek. The 60 watt bulbs may give off a light that is more yellow than the 120 watt.

It depends upon the type of light bulbs used, and what you mean by "light". Incandescent light bulbs are very efficient at converting electricity into light, but unfortunately they emit most of that light in the infrared band, which humans cannot see. Therefore, we describe incandescent bulbs as being inefficient in terms of converting electricity into visible light.
Generally, higher wattage incandescent light bulbs operate at higher temperatures, and they therefore emit a greater proportion of the light in the visible spectrum. Consequently it is common to say a 120 watt bulb emits more than twice the light of a 60 watt bulb. In truth, a 120 watt bulb emits almost exactly double the luminescent energy of a 60 watt bulb, but because the 120 watt emits a greater proportion of its energy in the visible spectrum, it is common to claim that the 120 watt bulb emits more than double the light of a 60 watt bulb.
The situation changes considerably when talking about fluorescent and LED bulbs, which emit the majority of their luminescent energy in the visible spectrum. That is why they are so popular, because they use much less electrical energy to emit the same amount of visible light, compared to incandescent light bulbs. As a general rule, a 120 watt fluorescent or LED bulb will emit about twice the visible light as a 60 watt bulb.
Watts is not a unit of light, but of power consumption. However, many people are familiar with the amount of light emitted from an incandescent lamp (bulb) of a given wattage, so that has become an unofficial way of expressing brightness. Many compact fluorescent packages are labeled with the incandescent wattage giving a similar light output.
If you used them simultaneously, probably around 1.46 million 60Watt bulbs.
You can only reduce amperage in a circut by reducing the number or size of devices plugged in to it. To make it easy, imagine you have a 120watt light bulb. Given your household voltage is normally 120v this would draw 1 amp, (volts X watts = amps). fifteen of these bulbs would draw 15 amps, the size of a commonly used circut breaker. The sixteenth light bulb added to the circut should trip the circut breaker or fuse to protect the wiring from overheating. If you chose to use 60watt bulbs instead you should be able to burn 30 of them before th breaker trips. Likewise if you needed 240watt bulbs, that same circut could only carry 7 of them.
Headlight bulbs, high and low beam, parking light bulbs, signal light bulbs, brake light bulbs, dash light bulbs, interior light bulbs, plate light bulbs, etc.
About as much as 15 typical (60watt each) light bulbs together. Or expressed in horsepower: about 1.2Hp Mains volts and ampere: 230 volt at 3.91 ampere = 900watt 110 volt at 8.18 ampere = 900watt
why light bulbs are fragile
In some light bulbs.
Light bulbs emit light.
bulbs emit light
* light bulbs can kill you be very carfull
there are 98 different kinds of light bulbs. including colored light bulbs
Fluorescent light bulbs You could also have energy star light bulbs.
Domestic light bulbs are simply the light bulbs (usually of the filament type) used in the home.
light bulbs use alternating current, batteries provide direct current, so you couldn't light the bulbs
Industrial light bulbs typically have larger wattage than commercial light bulbs. This is because commercial light bulbs are more commonly used in public as opposed to private homes.
Carbon light bulbs are a primitive form of light bulbs with a carbonized bamboo filament inside the bulb.
No. Light bulbs produce non-polarized light.
They are called halogen light bulbs
Thomas Edison invented light bulbs
There were about 10,000 light bulbs on Titanic.
Halogen light bulbs are a type of incandescent light bulbs and are filled with a halogen gas. The halogen gas gives the bulbs a longer life than traditional incandescent bulbs because it helps redeposit the evaporated tungsten back to the filament. Halogen light bulbs are not the same thing as compact fluorescent light bulbs (CFL bulbs), which have mercury inside and are often subject to state or local disposal regulations. Also, halogen light bulbs are not recyclable like CFL bulbs are.
Yes, e27 light bulbs are standard light bulbs in America. The e27 LED bulb is an indoor flood light. Review sellers to find ENERGY STAR rated light bulbs.
Incandescent bulbs are not hazardous. Fluorescent light bulbs contain Mercury which is a hazardous chemical.
Fluorescent lamps deliver more visible light than incandescent lamps using electric power at the same rate. (But incandescent lamps deliver more heat. Just depends on what purpose you're using light bulbs for.)
It is possible to have 2 light bulbs in a circuit.
