Lighting is one of the most important aspects of daily life. It gives us visibility and brightness, allowing us do tasks that require it. In addition, lighting is important for its decorative importance in modern homes and offices. Lighting ranges from natural to artificial light sources. Natural light sources are sunlight or moonlight. Artificial light sources are electric sources, such as incandescent light bulbs, halogen lamps, fluorescent lamps, etc. When choosing lighting sources, the power source, the type of light, and the color of the light should be taken into consideration. All types of lighting can have the same light intensity, but since different types of lights produce different types of lights, the desired lighting effect should be considered when making a selection. The shape of the fixture is important, since this determines how much direct light will be produced. Heat generated by the light source should also be considered; incandescent bulbs can generate a lot of heat, whereas LEDs and fluorescents produce very little. Lastly, energy-efficiency is always an important factor when selecting lighting. LED lights and fluorescents are typically the most energy-efficient evening sources. In conclusion, lighting has a major role in our daily lives. Therefore it is important to be aware of the different types of lights available and the factors to consider when selecting lighting.
