Lighting & Design Glossary

H
Halogen

Small incandescent bulb that uses halogen to stabilize the tungsten on the filament and extend the bulb's life. Learn more about Halogen bulbs and light bulb differences.

Hand-Tufted

One of the primary methods of creating a handwoven rug. A hand-tufted rug is created by repeatedly pushing wool yarn (or acrylic) through the rug's backing --which creates a "tuft." A "tufting gun" is used to assist in pushing the yarn through the backing. Hand-Tufted rugs are known for their durability and their intricate detailing, seen in many of the designs by Thomas Paul rugs.

HID

High Intensity Discharge. A type of light bulb that produces light by means of an electrical arc forming between tungsten electrodes. This arc--and overall light intensity--is facilitated by gas and metal salts within the enclosed tube. The result has high luminous efficacy. Various gases result in a variety of HIDs, including mercury vapor, metal halide, sodium vapor, xenon short-arc lamps, etc.

High Efficacy Lighting

In a general sense, energy efficient lamps/bulbs/light sources are considered to be high efficacy. However, high efficacy is usually carefully defined in state, local or federal building codes that require energy efficient lighting in new buildings and remodels.

Hollow-handled Knife

The hollow-handled knife, verses the monobloc, is formed from two pieces of metal (for the blade and the handle), strengthened through a heating and cooling process before being cemented together and sharpened. This type of knife is more expensive than a monobloc knife because it is stronger and the blade stays sharper longer.

Hollywood Regency

A take-off of 1930s Art Deco design, inspired by Hollywood's Golden Age, and especially focused on the opulent, glamorous elements. Details include an eclectic mix of fringed lampshades, crystal chandeliers, lacquered furniture, velvet drapes, etc. The intended emphasis is on entertaining and impressing. Furniture pieces are often inspired by vintage William Haines and Dorothy Draper designs.

Housing

A recessed housing is the protective safety covering around a recessed downlight. Both remodel and new home housing units are made.

Hybrid LED Light

A hybrid LED light is a single lighting unit that uses both an LED light source and a non-LED light source. This might be seen in wall sconces with gooseneck reading lights, for example.
