Depends on what the cows were doing!
in the 99cents store they sell 100watt light bulbs. You can also find them in a hardware store
Yes A 100watt light bulb left on for 10 hours will use a much electricity as a 1 Kilowatt fire left on for one hour. An energy efficient light bulb giving out the same amount of light as a 100watt bulb, only actually uses 20watts of electricity. That is 1/5th of the electricity, it will need to be on for 50 hours to use as much as a 1 Kilowatt fire left on for one hour. This will reduce your electric bill but the bulbs are more expensive than old 100watt bulbs (but the energy efficient bulbs last 6-8 times longer! so this balances out).
The type of light bulbs thyat are needed for pathway lighting are LED pathway lights with a motion sensor. They come in a frosted glass finish lasting up to 100,000 hours.

Many of Edison's first bulbs lasted less than 40 hours.
The average lifespan of LED light bulbs is around 25,000 to 50,000 hours, which is significantly longer than traditional incandescent bulbs.
They sure can. You might need a nail and a penny, but a potato can power a lightbulb.
It depends on the type of light bulb and its wattage. Typically, LED bulbs can last up to 25,000 hours or more, while incandescent bulbs last around 1,000 hours. It's recommended to turn off lights when not in use to prolong their lifespan.
Solar Panels Low energy light bulbs Switch off (or remove) bulbs that are not needed.
The number of 48 fluorescent light bulbs needed to fully illuminate the entire office space depends on the size of the space and the brightness of the bulbs. It is recommended to consult with a lighting specialist to determine the exact number needed for optimal illumination.
