Using a 4.5V lamp in a 3.0V flashlight can potentially damage both the lamp and the flashlight. The higher voltage could cause the lamp to overheat and burn out prematurely. It's best to use the appropriate voltage rating for both the lamp and the flashlight to ensure optimal performance and longevity.
A lava lamp can last for several years with proper care and maintenance. However, the lifespan of a lava lamp ultimately depends on how often it is used and if it is maintained according to the manufacturer's instructions.
The glow of luminol does not last long, typically a few seconds to a minute. After the chemical reaction occurs and the luminescence fades, the glow will not be visible.
The amount of energy stored in the batteries is typically higher than the total amount of light output by the flashlight, as some energy is lost as heat during the conversion process. The efficiency of the flashlight will determine how much of the stored energy is actually converted into light.
Crank flashlights are very handy devices that are particularly useful in a pinch. No need to worry about charging the flashlight or ensuring it has fresh batteries, the crank flashlight is a great last resort and will always light up your campsite when you need it.GeneratorThe crank flashlight contains a small generator much like the ones that are used to provide electricity around the country. The difference is that the flashlight's generator, also called a dynamo, is powered by manual cranking of the arm.InductionThe principal behind the generator is that of induction. When you move a coil of wire through a magnetic field, a voltage is induced into the wire, which then creates electrical current that flows through the circuit. Inside your crank-powered flashlight is a wire coil that is inside a magnetic field. When you crank the arm of the flashlight, you are actually moving this coil in the magnetic field. As the coil moves, voltage is induced and current then flows through the circuitry and lights the bulb of the flashlight.BatteriesYou've probably noticed that you can crank your flashlight for a few minutes and then get a reliable light source for a while afterward without actively cranking. This is because the crank flashlight has rechargeable battery cells inside that store the energy that you've created from cranking. In this way you don't have to actively crank to use the flashlight, but can crank and then have the flashlight operate on batteries.Read more: How Does a Crank Flashlight Work? | eHow.com http://www.ehow.com/how-does_4911443_crank-flashlight-work.html#ixzz1Xz4cG0feELEPHANT!
Sounds can last longer due to factors like the physical properties of the vibrating object or medium producing the sound, the amount of energy driving the vibration, and the environment where the sound is traveling. Sounds with more energy or produced by objects with slower rates of damping will typically last longer than sounds with less energy or produced by quickly dissipating vibrations.

The Maglite flashlight includes a high performance LED bulb which is brighter and more energy efficient. This means that the battery will last longer.
Use 1/4, 1/5 the energy and last much longer.
it depends on the battery and how much you use the flashlight
That's going to depend on how often, and for how long, the flashlight is turned on.
I would prefer u panasonic as it is a japanese product while not sure about energizer. It depends upon the flashlight also.

I Did A Project On It. They Only last A Few Hours
It's the other way around - the batteries powers the flashlight. There's no set answer to that. It depends on the capacity/size of the battery, and how powerful the flashlight is.

it depends what kind flashlight you use, and the temperature has effection on it too.
The lifespan of 3 AAA batteries in a flashlight depends on various factors such as the capacity of the batteries, the power consumption of the flashlight, and the usage pattern. On average, standard alkaline AAA batteries have a capacity of around 1000-1200 mAh each. If the flashlight consumes 100 mA of current, the batteries could last approximately 10-12 hours. However, if the flashlight has a higher power consumption, the batteries may last for a shorter period.
