it's useful for light and safety.
The light bulb is useful because it lights up places!
The useful energy in a light bulb is the light that it emits. When electricity flows through the filament of a light bulb, it produces light energy that we can see and use for illumination.
The useful energy of a light bulb is the light it emits, which is used for illumination. This is the intended function of the light bulb, as it allows us to see and perform tasks in dark environments.

The useful energy that comes out of a light bulb is primarily in the form of light and heat. The electrical energy is converted into light energy that illuminates the surroundings and heat energy that warms up the light bulb and its surroundings.
A lamp shade very very useful in a house it serves to protect eye sight from the glare of a light bulb and helps to control the brightness of the bulb.
A burning light bulb produces mainly light energy as well as heat energy. When electricity passes through the bulb's filament, it heats up and emits visible light as well as infrared radiation, which we perceive as heat.
A light bulb emits light energy, which is useful for illuminating a space and providing visibility. Some light bulbs also produce heat energy, although this is often considered a byproduct rather than a primary source of useful energy.
The positive is that it gives light, which is useful at night or in dark corners.
Nuclear energy is not useful in powering a flashlight because it is not readily convertible into electrical energy that can power the light bulb in a flashlight.
