it depends,the flourecent kind hols 60 watts,lumens has 120 and they last for 10,000 hours.
1400 hours
Exsacly 13.7 hours
A flourescent light bulb lasts between 6000 to 18000 hours.
When you flip the switch, it completes the electrical circuit and allows current to flow instantly through the wires to reach the light bulb, causing it to light up. The speed of electricity traveling through wires is almost instantaneous, so the light bulb lights up immediately after the switch is turned on, regardless of the distance from the switch to the bulb.
Usually around 900 hours.
Any where from 3000-6000 hours :)
The lifespan of a light bulb varies depending on the type of bulb and how often it is used. Typically, incandescent bulbs last around 1,000 hours, while LED bulbs can last up to 25,000 hours or more. Factors such as wattage, quality of the bulb, and usage patterns all contribute to how long a light bulb will last before burning out.
2000,00000,0000000 seconds or..... 15 hours
A night light bulb typically lasts around 1,000 to 2,000 hours when used continuously. This can vary depending on the type and quality of the bulb.
The duration that a fruit can power a light bulb will vary depending on the type of fruit and the size of the bulb. Generally, fruits can power a simple LED light for a few hours to a few days.
Thomas Edison's first successful light bulb lasted for about 13.5 hours when he first demonstrated it. However, he and his team later improved the design to last for over 1500 hours.
The average bulb life is approximately 100 hours.
