i dont know ether if you get the answer can u send it to me plz
a nightlight can cost a few dollars depending on the type of nightlight it is such as a bulb or sensor. the decor of the nightlight can be factored in the cost as well.
50-Voltage
well you can get a hallow ball no holes attach a fuse fill the hallow ball with gun powder
Typo: Who made the (First) light bulb? The first light bulb ever created was by Humphry Davy (Englishman) in 1809. Thomas Alva Edison made the bulb better in 1875. Most of us have heard of Thomas, but not many have heard that Humphry was the original creator, but if it weren't for him, we would not have had much good technology.
Florescent light bulbs produce a similar amount of light with much less power than incandescent light bulbs. Their initial cost is paid back in energy savings. They also last a lot longer. I exchanged every light in my house for florescent bulbs years ago and I haven't changed more than 4 or 5 in all that time. LED bulbs are now on the market and are very expensive. But they use even less power to produce similar light and last many times longer than florescent bulbs. They are quite expensive, but what you get is an almost permanent bulb. In the future we will tell our grandchildren how we used to change light bulbs and they won't understand. I see a day when the bulbs become permanent parts of light fixtures and will not be replaceable in any typical sense.
Thomas Edison's light bulb was patented in 1879. The cost of the original light bulb produced by Edison was around $1, which was quite expensive at that time.
the price of the bulb
about 2-3 dolers
The first commercially available light bulb cost $1 in 1881, which was three years after Thomas Edison developed the first practical incandescent light bulb. The Seattle Times reveals the $1 price in 1881 translates to $23 in 2013. By 1910, the cost of a light bulb dropped to 17 cents.
a buck for the bulb and 2-3 minutes of your time to replace it
A 0 Watt bulb does not consume electric power so the cost is zero.
typically, you only change the bulb (it the bulb light is out). they usually cost a few dollars, if it is a busted headlight, do not know.
Flourescent light bulbs are approximately double the price of a standard bulb. There is an advantage to them though, they last longer and are more energy efficient.
I am not sure of the exact figure but it must of cost a lot, there weren't many lightbulbs in that time.
ahm...depends on the cost per watt charged by your local provider... how much is it?
about 2.00 dollars. it depends on the size and shape and the number of volts you get!
