Lighting plays an important role in all aspects of life, from illuminating homes and workplaces to providing security on residential properties. It may also be used to create a specific atmosphere such as in entertainment venues and restaurants. For these reasons, the considerations for what type of lighting to use can be quite complex. Indoor lighting typically utilizes a combination of natural and artificial lighting. Natural light is often used when it is available, as it is free and often provides the best type of light. Artificial lighting takes many forms, including incandescent, fluorescent, and halogen bulbs. Some of the considerations when deciding what type of light to use include the intensity, colour, and cost as well as the environmental impact. Outdoor lighting often serves both practical and aesthetic purposes. For security, lighting can be used to deter intruders by increasing visibility. For architectural or landscaping purposes, lighting can be used to illuminate pathways, create shadows, and draw the eye to particular elements. The type of outdoor lighting used may vary based on the surrounding environment, with options such as solar-powered lights, LED lighting, floodlights, spotlights, or landscape lighting. Overall, lighting is a multi-faceted tool that can be used to create different visuals and atmospheres. From providing illumination to designing a specific look, lighting is an essential component of both indoor and outdoor spaces.
