To determine your fixture type, review the product in detail and compare it against the definitions provided below. You may allow marketing text to influence your decision but do not select fixture types based on marketing text when it clearly violates these fixture definitions. In these cases of definition and marketing text conflict, adhere to the fixture type definitions and make sure to keyword all the other fixture types mentioned in the manufacturer's product webpage and spec sheet.

Contents

Accent light

Kurt Versen spec sheet showing adjustability, qualifying it as an accent light.
Almost always adjustable, designed to provide a focused beam of light to accent or highlight an object. Also called “adjustable” or “spot”. The fixture has optics and throws light. If a linear fixture is adjustable and called out as an accent light (ie Color Kinetics) it does not qualify it as an accent light. Strip lights have wide distribution and do not focus on a particular area as an accent light should.

Area / Roadway light

Outdoor luminaire, usually pole-mounted, designed to provide a large-scale and efficient pattern of light at the ground. Also called “street light”, “shoebox”, “cobra-head”, “lantern”, “standard” (looks like it belongs on the side of a highway, or otherwise tall high power light to light an area, parking lot, etc.) Distributions (Type II type III etc) are no longer cataloged individually. Mention distribution types in the eLumit notes verbatim.

Bollard

Outdoor luminaire designed to provide a small-scale and efficient pattern of light at the ground. (fixture vertical, surface mounted, possibly to block vehicles, creates barrier, often found at docks.)

When entering bollards if the fixture head (which holds the lamp) dimension varies, then enter separate entries for each variation in dimensions. If the variation in dimensions are restricted to the pole/stand itself (not including the fixture head), then dimensions should not get different records but should be noted. e.g. Intense lighting's Vortech Bollard.

Chandelier

Fixture with multiple heads, lamps, decorative.

Cove light

Luminaire optimized for cove lighting applications (uplighting a ceiling, coffer, or other surface from an architectural cove), where small size and specific light distribution characteristics are desired. Sometimes adjustable. (basically strip light or other, with reflector to throw light out of cove. If named cove but has no reflector and specific cove optics, probably strip light.)

Decorative pendant

suspended fixture, decorative features.


Decorative Style

Shade Material, Finish, Opacity

Body

Downlight

Luminaire designed to light an area directly below the fixture. Variable beam distributions/widths, not adjustable. If a fixture is presented as a downlight but the spec sheet mentions that the fixture can be installed as an uplight, enter a record for the fixture as an uplight as well. To qualify as a downlight more that 89% of the light must be directed down. If the spec sheet is silent on this point, enter the fixture with your best estimate. To verify, after appending the ies file, on part 4 of the admin entry site, check the dialog box for "Percent Up/Percent Down". If the entered fixture type was entered incorrectly, the record must be deleted and re-entered. If there is no ies file or other definitive photometric report, enter fixture type as your best guess, informed by any manufacturer information provided.

Fiber optics/light pipe

Luminaire, fiber, or illuminator components of a fiber optic system. (light box, fiber optics running out, ending in accessory that points light)

Floodlight

Adjustable luminaire designed to provide an efficient and specific pattern of light coverage. Also called “sign lighter”, “wall pack”, “apron light”, “sports lighter”. (wide spread, filling space with light) IES files should have NEMA distributions 2x3, 1x1, etc. (exterior floodlights). Floodlight term is often used inappropriately. See distribution. Light areas outside, on building, exterior usually. Usually higher wattage than landscape lights. See marketing/application keywords, if there is an emphasis on facades, signs, buildings or wall wash(wall grazing) then there is more of a case for flood lighting.

High-bay

High-output, efficient interior luminaire generally designed for high mounting heights. (exposed downlight, industrial looking)

Industrial

High-efficiency, fluorescent luminaire consisting of a strip light with side-mounted reflectors. Also called “shop light”. (very functional, ugly, typically housing boring fluorescent lamps.) A strip light that is intended for a specific environment (ie manufacturing, public facilities, salt or corrosive environments, etc.) should be industrial, often with the distinguishing side reflectors and other application specific options.

Landscape light

Outdoor luminaire, almost always adjustable, designed for small-scale floodlight and accent lighting. Often uses remote low voltage power supply.

Parking garage light

Luminaire optimized for parking garage applications (surface-mounted to low height structure) where good glare control and efficient wide light distribution are required. (Typically HID, HPS or FL fixture, high power, efficiency, functional)

Path light

Luminaire designed to light a walkway, ramp, etc., (implies directional) usually very low mounting height, relatively low light output.

Perimeter wall slot

A recessed, usually linear lighting system, usually fluorescent, designed to provide grazing light at a wall (wall grazer). Can be MH or incandescent or other.

Sconce/marker light

Sconces are designed to provide a sense of brightness at a wall and marker lights provide brightness (blob of light) for other surfaces for decorative or wayfinding purposes. A sconce or marker light will not have any performance features. If the fixture is wall mounted and has optics or reflectors, the fixture is not a sconce; it is more likely an up/downlight, up, down light or even area/roadway light. Most bathroom vanity fixtures are considered sconces. See Boca 650 for marker light.

Step light

Luminaire designed specifically for stair/ramp lighting applications, where the luminaire is recessed in the stair riser or an adjacent wall.

Strip light

Luminaire consisting of bare lamps and a housing channel or flexible strip. Also called “shop light” (fluorescent), "tivoli lights" (incandescent), "xenon strip" (halogen/xenon). light in a strip, sometimes flexible. Linear LED fixtures are strip lights - keyword unqualified fixture types if called out by manufacturer.

Table/floor lamp

Task light

Luminaire designed to focus light directly on a work surface, mounted at or very close to the work surface itself. “desk lamp”, “undercabinet”, “undercounter” (for specific tasks, light desk lighting.) *Important* - whenever any of the following terms are used for these task lights, keyword the rest of the list if they apply. [display, retail, shelf light, millwork, kitchen, undercabinet, under cabinet, task, tasklight]. Also picture lights (painting)

Teleconference fixture

Luminaire specifically designed for teleconference room applications where special light distribution and glare control are required.

Troffer

Interior fluorescent downlight generally designed to integrate with suspended ceiling grids. Also called “parabolic”, “2x4”, “2x2”, etc. In eLumit, troffers also include recessed direct/indirect "ambient" fixtures with perf baskets, etc. (ugly 2x4, 4x4, 1x4 [or 6"x2 etc] fixtures, FL, generic old offices, with louvers)

Underwater light

Submersible luminaire designed for pool, fountain, and other applications requiring underwater operation.

Up/downlight

Luminaire designed to provide both uplight and downlight, sometimes with multiple lamp sources. Also called “direct/indirect”, “ambient”. (at least 10% up or down, not just spillover, functional)

Uplight

Luminaire designed to provide indirect lighting only. Also called “indirect”, “ambient”. In-ground uplights that are adjustable are still considered uplights, not accent lights. To qualify as an uplight more that 89% of the light must be directed up. If the spec sheet is silent on this point, enter the fixture with your best estimate. To verify, after appending the ies file, on part 4 of the admin entry site, check the dialog box for "Percent Up/Percent Down". If the entered fixture type was entered incorrectly, the record must be deleted and re-entered. If there is no ies file or other definitive photometric report, enter fixture type as your best guess, informed by any manufacturer information provided.

Wallwasher

Luminaire designed to light a wall from the ceiling. Wallwash applications and specialized luminaires include single wall, corner, and double (two opposing walls) specifically for getting wall washed with light, close to ceiling line, no scallops. Stack lights, usually double and grouped with wallwashers are made for lighting library or similar stacks. See Prudential P-54 or P-5600. If stack light distribution is like a wallwasher, make it so. Blob gets downlight. Make sure to keyword stacklight. Inground uplights, even with Wallwash reflectors, are NOT wallwashers.

If a product has a wall wash reflector but does not necessarily have wall wash optics, defer to manufacturer text and call it a wall wash.

If a wall wash candidate is adjustable vertically, then it is not a wall wash fixture.

Wallwasher Type

Select "-All-" if single, double or corner are not specified explicitly.

Wraparound

Fluorescent luminaire consisting of a lens that wraps around the entire fixture body, designed to distribute light from floor to ceiling. This is typically a more architectural fixture, so it should not be confused with more functional industrial fixtures with lenses for environment specific uses.
