Terms to aid your search for the perfect light
Shortly after venturing into the world of lighting, you'll probably realize that it's a bit more complex than you might have thought. Incandescent, fluorescent, downrods, baffle - it's easy to get lost out there. Our glossary of lighting-related terms will aid your search for the perfect light.

Key Terms

Ambient: Ambient light, also known as "general light", is an overall level of lighting in your room. Ambient light should provide a comfortable amount of light to suit how the room is used.
Base: The decorative body of the lamp, a base can be constructed from an array of materials: metal, brass, porcelain, crystal, hydrocal, or wood to name a few. Bases should be solidly constructed to resist tipping during normal use.
Color Rendering Index: Light bulbs offer a varying range of attributes that can produce different light outputs and qualities. The color rendering index (CRI) provides a base of mesaurability to render color accurately and consistently.
Color Temperature: Color characteristics of light (temperatures) measure the appearance of the light from warm (yellows/red) to cool (white). Color temperature is rated in degrees of Kelvin and do not reflect the physical temperature (or heat) of a lamp. Light sources such as incandescent bulbs (2700 degrees Kelvin) and halogen lamps (3000 degrees Kelvin)are at each end of the color spectrum.
Dimmer Switch: Gradually increases/decreases light intensity. Most torchieres are equipped with dimmers or high/low switches.
Downlight: A light fixture that concentrates light in a downward direction. Most often this refers to recessed lighting, though many ceiling fixtures now have more concentrated beams of light.
Non-unifrom Downlighting: Non-uniform downlighting uses less light sources and delivers a more "individualized" beam spread of light. This lighting technique creates a more interesting visual effect in a space as the beams do not overlap as in general uniform downlighting. Unifrom Downlighting: Unifrom illumination bathes horizontal surfaces in light. Typically a general lighting technique, uniform illumination adds little dramatic impact to a space.
Downrods: An accessory for pendants and chandeliers to add length
General Lighting: General Lighting provides an area with overall illumination. General lighting is basically the lighting that replaces sunlight and is fundamental to a lighting plan.
Lumens: The amount of light a bulb produces.
Swag: Decorative motif, image of a garland of fruit and flowers or of a length of cloth, tied with ribbons and attached to a background. If tied at both ends and suspended from them in a loop, a swag is generally called a festoon.
Task Lighting: Task lighting is for those areas where tasks or activities such as reading, paying bills, etc. take place. Task lighting should work with a room's general lighting and enhances the use of a room. Task lighting can be provided by adding portable lamps, undercabinet lighting as well as the addition of recessed lights at specific areas.
UL and CUL: Underwriters Laboratory, Inc., like Electrical Testing Laboratory (ETL), is an independent, not-for-profit product safety testing and certification organization.
Uplighting: Uplighting visually expands a room by providing ambient light. Use them as a complement to recessed down lighting, and place them where they appear aesthetically balanced in the room.
Wattage: The amount of electricity consumed by a bulb.
Wall Lighting: The illumination of vertical surfaces can impact that perception of a space more than any other type of lighting. Light reflecting off walls creates a bright, spacious feel and adds visual interest. Dramatic effects can be achieved with light to illuminate vertical surfaces and highlight objects. Through proper lighting selection and placement a room can appear more spacious and interesting.
Grazing: For dramatic effect on textured surfaces such as stucco, stone or brick, place fixtures 6-12 inches away from the wall. Grazing is not recommended on smooth surfaces as surface imperfections will be exaggerated.
Light Scallops: Light scallop is an effect created when the fixture is placed closer to the wall resulting in a more concentrated and tighter scallop. Scallop light effects are often a part of the lighting plan for added drama, however they can be inadvertently created is fixture placement is not properly calculated.
Wall Washing: For a gentle and even illumination of a vertical space, place fixtures the same distance apart as they are from the wall. Wall washing is best suited for smooth surfaces.
