A Watt is a Joule per second. Joules measure energy and Watts measure power, which is the rate of energy used. Therefore, if you use a 60 Watt light bulb for 10 seconds, you consume 600 Joules.
fluorescents are about 5x as efficientso a 12W will give about as much light
no because it would blow up because the socket would draw 13 watt not 9 watt
No, a light bulb will not light up if electricity does not reach it. Electricity is required to flow through the filament in the bulb to generate light. If there is no electrical current, the bulb will not illuminate.
No, oranges cannot light a light bulb because they do not produce enough electricity or energy to generate light in a light bulb. Oranges do not have the capacity to function as a power source for a light bulb.

60 Watts is the amount of electrical power the bulb uses when it is switched on.
Yes if it is a 12 volt DC bulb.
Power = Current * Voltage Current = Power / Voltage Current = 60 W / 120 V Curretn = 0.5 A

A 60-watt incandescent light bulb typically lasts about 1,000 hours of use. However, if you use a more energy-efficient option like a compact fluorescent lamp (CFL) or an LED bulb, they can last significantly longer—around 10,000 to 25,000 hours, respectively. The actual lifespan can vary based on usage patterns and the quality of the bulb.
Under the right circumstances, yes. So will, for example, a 15 watt soldering iron. It just won't melt very much. It is not the wattage that determines the temperature, it is the insulation (or lack thereof) around the bulb and chocolate that determine it.
Energy.
So to replace a traditional 60-watt bulb, buy a 15-watt CFL: 60-watt incandescent / 4 = 15 watts. Note: Some brands of 60-watt equivalent CFLs still do not seem to give off as much light as a 60watt incandescent bulb.
"60 watts" means "60 joules every second". That's what a '60 watt' bulb is designed to consume. If you put 100 joules of energy into a light bulb, 100 joules of energy are going to come out of it, one way or another. Either that energy will be converted into light and heat by the bulb's filament, or else it won't get consumed at all, and it'll come out the other side of the bulb and still be available for use in some other device. So, comparing output energy to input energy is not an effective way to evaluate the efficiency of a light bulb. What you need to do, in order to compare the economy and effectiveness of light bulbs, is to compare LIGHT output to input ENERGY.

It is not recommended to upgrade the bulb wattage in a projector as it may cause overheating and damage the internal components. Stick to the manufacturer's recommended wattage for the best performance and safety.
