The mood light will last as long as the bulbs life, which has a lifetime of an average household light bulb. once the bulb burns out, one must replace the bulb with another mood light bulb.
Lewis Latimer invented the long lasting light bulb.
Yes, the inside of a light bulb is vaccum sealed to increase the lifespan and brightness of the bulb. If there was air in there, the filiment would burn up and not last very long. This was an important discovery made by Thomas Edison when he invented the light bulb.
Edison failed many times - no one knows how many - to make a filament for a light bulb that would last a long time. He did not invent the light bulb - he was working on a BETTER light bulb that would last longer.
A light bulb is dangerous because if leave it on too long it will burn.
A Tube-light !
he improved the light bulb when he saw that it did not last long and broke easily
A: the answer lies in the use if never turn on my guess is forever.But seriously it depends on heat when operational. So nobody can define how long in my opinion
Thomas Edison had trialled many experiments his most famous one would be, where he created the first long lasting electric light bulb
There is not any detailed information on how long it took Thomas Edison to create the first light bulb. We do however know the first electric light bulb was patented in 1879.
i think it takes about 10 seconds if you already have the light bulb in your hand.
Thomas Edison was the who pateneted the first light bulb
