Accent lighting is used mainly to focus on a specific point of interest or to achieve a desired effect. This type of lighting gives the impression of a larger room. It is more frequently used to highlight an architectural feature, a plant (in outdoor layout), a sculpture, or a collection of objects. As a general rule, effective accent lighting requires the installation of three times more light on the focal point than ambient lighting generally provides. http://www.weiliram.com/explosion-proof-light/
