Following are general definitions of some of the common terms used in the lighting industry as well as some of the terms we use in describing our products and techniques:
Damp Location – Exterior locations where the fixture is not directly exposed to wet conditions such as a driven rain or snow.
Dark Sky – An international movement to reduce light pollution. The advantages of reducing light pollution include an increased number of stars visible at night, reducing the effects of electric lighting on the environment, improving the well-being, health, and safety of both people and wildlife, and cutting down on energy usage.
Distressed – A random texture that is hand-applied to surfaces of our metals.
Dry Location – Interior locations.
Full Cutoff – A Dark Sky term used to describe luminaires that have no direct uplight (no light emitted above horizontal). However, in addition to that limitation, the Illuminating Engineering Society of North America (IESNA) definition also requires luminaires to comply with the glare requirement limiting intensity of light from the luminaire in the region between 80° and 90°.
Lamp – Generic term for a light bulb of any type. Our fixtures are provided without lamps.
Lamp Life – The average rated life of a lamp in hours as provided by the lamp manufacturer.
Lumens – The unit used to measure the quantity of light output by a lamp. Since our fixtures are decorative in nature, we do not provide photometric data which describes the light output of our fixtures.
Peened/Peening – A random, hand-applied texture of round indentations achieved with a ball-peen hammer.
Punching – Hand-punched holes used for decoration and dramatic light patterns in our fixtures.
Tinning – On copper and brass, we use this technique to apply solder to the metal surface to achieve a pewter-like color in decorative patterns. It is usually bordered by punching around the tinned area.
Voltage – The measure of electrical power supply brought to the fixture by the building’s wiring. Typically, residential wiring is 120 volt while commercial wiring can be 120 or 277 volt. For a 277 volt power supply we can provide compact fluorescent or integrated LED lamping in our fixtures.
Watts/Wattage – The unit used to measure power consumption of a lamp. Our fixtures are labeled with the maximum wattage that may be used. Refer to this handy chart for wattage equivalencies and lumen output across incandescents, CFLs, and LEDs:
Wet Location – Exterior locations where the fixture is directly exposed to wet conditions such as a driven rain or snow.
