In outer space, light will just go on, and on, and on. We can currently see light from galaxies that is several billion light-years ago (and was emitted billions of years ago). So, light will go on indefinitely, unless it is stopped by something.
No, lasers are not infinite sources of light and energy. They require a power source to operate and have limitations on their output.
The sources that can give out their own light are "Light Sources" and the same opposite the sources which can not give out their own light are know as Non Light Sources .
No, different light sources have different levels of brightness depending on factors like their power output, distance from the observer, and the direction of emission. For example, an LED light bulb may appear brighter than a candle even though both are light sources, due to differences in their luminous intensity.
Electricity itself is not a light source, but it can power light sources such as light bulbs, LEDs, and fluorescent tubes that produce light. When electricity flows through these devices, it generates light energy.
The two main sources of light energy are natural light from the sun and artificial light from sources like light bulbs and lamps. Both sources produce electromagnetic radiation that our eyes perceive as light.
light is the source of energy.

By far the hottest of the two light sources is the light bulb.

Electricity, which generally comes from power plants, but can come from batteries, solar panels, wind turbines
The sources that can give out their own light are "Light Sources" and the same opposite the sources which can not give out their own light are know as Non Light Sources .
The motion light may not turn off due to a malfunction in the sensor, a power issue, or interference from other light sources.

Power is how fast energy is flowing. Most sources of energy can be traced back ultimately to the Sun's heat and light.
