Gallery: 15 Green Lamps to Light up Your Life
Different types of lighting
Directional lighting refers to light fixtures that focus illumination in a single direction. When set in a series, these fixtures provide dynamic focus to a room and can efficiently distribute light throughout a room. Directional lighting is commonly provided by bulbs affixed to a ceiling-mounted track, where individual lights can be angled and rotated on a pivot. Another popular choice comes in the form of recessed downward lighting, where the light is regulated by "can fixtures."
Task lighting is a specific type of directional lighting that is focuses illumination upon a specific area where a task needs to be performed. Task lighting should not be used to replace overall lighting needs, but rather to compliment or fill the void of existing lighting. Task lighting typically comes in the form of table and desk lamps, clamp-type flexible arm lamps, book lights, and for the more adventurous, headlights.
Ambient lighting is designed to illuminate an entire room in a uniform and low-key manner. Ambient lighting should never be harsh on the eyes -- it should create a comfortable environment that accommodates basic lighting needs. Popular lighting solutions for achieving this type of illumination include floor lamps, chandeliers, hanging lamps with low-watt bulbs, or hanging lamps filtered by cylindrical shades.
