Most light bulbs fit into a socket which provide a high voltage level of electricity. If the socket is turned on, even if the bulb is out, there is a real danger of an electric shock.Incandescent bulbs get very hot when they are turned on, and take some time to cool off. Touching the bulb when it is hot can cause burns.Most light bulbs are made of glass, which means that they can break easily.

Another way to identify low energy bulbs is to look for the lumens, which measure the brightness of the bulb. Low energy bulbs can produce the same amount of light (or lumens) as more traditional bulb bulbs while using less energy. For example, a 60-watt incandescent bulb produces around 800 lumens, while a 9-watt LED bulb can produce the same ...

The lifespan of a light bulb depends on several factors, including the type of bulb, the wattage, and how often it is used. On average, incandescent bulbs last for about 750-1,000 hours, while fluorescent bulbs last for about 8,000-10,000 hours. LED bulbs are known for their long lifespan, with some lasting 25,000 hours or more.
