Sir Joseph Swan's lightbulb lasts for about 13 hours
When a light bulb gives its last glimmer, it means that the filament inside the bulb has burned out. This results in the light bulb no longer being able to produce light. When this happens, the bulb needs to be replaced with a new one.
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.
When bulbs are connected in a series circuit, each bulb depends on the voltage from the previous bulb to light up. If the last bulb doesn't glow, it may indicate that there is a break in the circuit somewhere before that bulb, such as a loose connection or a blown fuse. This interruption in the circuit would prevent the flow of electricity to the last bulb, causing it not to light up.
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.
Thomas Edison replaced the filament in his incandescent light bulb with a carbonized bamboo filament in 1880. This improvement helped the light bulb last longer and shine brighter.
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.

he improved the light bulb when he saw that it did not last long and broke easily
Lewis Latimer improved the light bulb in 1881 by inventing a more durable carbon filament that allowed the light bulb to last longer. His improvements made the light bulb more practical and accessible for everyday use.
