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-uniform 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.

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.

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.

 

Styles

Antique: Whether you wish to bring back the days of the Pilgrims or desire the styles from “Gone with the Wind”, the antique fixture sends you back to days of yore. These fixtures will bring a warming touch to your home. Usually characterized by burnished or brushed metal, this style is often reflected in traditional fixtures as well.

Casual: These furnishings are comfortable, warm, inviting, and homey. Simple details, textured elements, and restful horizontal lines characterize this style. Rectangular and softly curved elements contribute to a casual feel. The furniture is large in scale and selected for comfort and utility with less emphasis on design or design elements.

Contemporary/Modern: Contemporary and modern pieces feature neutral elements and bold color. Clean lines, sculptural furnishings, art, industrial elements and bold color characterize these furnishings.

Contemporary fixtures often incorporate classic and traditional features in subtle, understated ways. Its simplicity and clean lines combine with strong geometric shapes and symmetry, incorporating classic and traditional features in sleek and understated ways. The inspiration for these fixtures is drawn from manufacturing/architecture and organic forms.

Country: This furniture is casual and unpretentious. Almost exclusively light and warm colored woods and metals, this can be thought of having a certain “rustic class”. Often containing a period flavor, this style is both rustic and romantic with graceful curves and comfortable style.

Mission: An early 20th century American offshoot of the Arts and Crafts Movement, mission can be identified by its clean straight lines, evoking the same organic beauty as Frank Lloyd Wright’s architectural designs. Its style is simple, utilitarian and uniquely American. Mission style fixtures are the distinctive product of the simple woodworking and exposed joinery used by Spanish missionaries in Southwestern North America. Fumed oak is the material most characteristic of this style, and accents of warm colored fabrics and leathers complete the look.

Oriental: Influenced by the people and culture of the East/Orient, oriental fixtures will add a look of romance and intrigue to your home. Oriental furnishings are most often characterized by porcelain lamp bases, paper lanterns, shoji screens, sleek lines, ornate details of flowers or animals and metallic finishes. Often finished in the browns and gold’s’ that are influenced by historic empires this style can blend with either traditional or modern décor.

Rustic: The rustic style is cozy and welcoming. Rustic fixtures offer the charming comforts of an alpine cabin. They inspire the intimate coziness of a ski lodge in Aspen or a log cabin in the woods of Maine. Characterized by natural finishes with emphasis on grains, these fixtures invite hibernation – minus the bears. The Rustic look is often exemplified by antler chandeliers or ceiling fan light kits. If you are looking for a rustic lamp, we carry a variety of table lamps accented by deer, moose and antler.

Southwestern: There are distinct characteristics in the southwestern style that can easily be explained by imagining a desert scene. Picture all colors of the desert, the green of cactus, the red mountains of the Grand Canyon, and the Native American heritage that comes from the Arizona, New Mexico regions of the United States. The all natural organic version of southwestern is over scaled furniture made from log pole, and the use of rugged materials such as iron, stones and wood. The city version of southwestern uses plastic cactus decorations and wall hangings, coyote figurines and the use of peach and teal coloring. General Colors and Characteristics are Native American Indian accents, organic materials such as iron, adobe, wood and smooth rocks, brightly-colored patterned fabrics inter mixed with natural colors, oversized furniture and colors that are seen in the desert sunset, hills and prairies.

Tiffany: This style loosely refers to glass-shaded lamps, windows and other decor made from a mosaic of opalescent colored glass panels. Invented by Louis Comfort Tiffany, this look applies the Art Nouveau stylized designs from the early 20th century. Tiffany presents a cornucopia of themes - stained glass Art Deco lighting and retro lamps are popular today. Mission and Prairie styled lamps, Bungalow chandeliers and Arts & Crafts lanterns come alive in vibrant colors and styles.

Traditional: Based on historic design models, this style is characteristically ornate, orderly, and bold. Straight lines are often contrasted with curved details, and brass, iron, and hand-painted wood often appears. More grand than casual, these furnishings have ornate or showy details and have often old world flair. The classic details of traditional furniture are reflections of the periods and influences of years gone by. The classic details of traditional fixtures are reflections of the periods and influences of years gone by; Colonial, French Country and Neo-Classical design ideals are blended in this style. You will recognize it when you see it – the traditional furniture style has been the popular choice for home furnishings for over a century.

Transitional: Transitional bridges the gap between too ornate and too sleek. While the materials used are more similar to traditional furniture (lots of metals and heavy woods), the lines are more open and clean without being too sleek and sterile. Transitional fixtures are versatile, blending seamlessly into almost any setting. Transitional fixtures combine both contemporary and traditional styles by joining austere lines with fancy curves with sleek, brushed metals. It easily adapts and blends in with a wide range of styles. The versatility of transitional fixtures make it a good choice if you’re not sure which of the less flexible styles suits your taste or your home – transitional fixtures work in pretty much any setting.
