Products represent a more detailed level of information than spec sheets. They basically represent the different lamp type version of a spec sheet's offering (along with other significant attribute differentiation listed below). Products are identified through catalog numbers and are linked to a single spec sheet. There may be one to several products associated with a specification sheet. Please ensure all product details pertain only to US products and options.

Product Record Requirements

Significant Attributes

  • Lamp Type
  • Lamp Spec (for Premier Members only)
  • Fixture Type
  • Fixed sizes (4’ long, 8’ long, 2x4, etc.)

Insignificant attributes (Additional products not required)

Determine your Catalog Numbers

Catalog numbers are created with the following guidelines. The goal is to create a meaningful representation for users that accurately reflects the naming structure present in the spec sheet, and that is consistent with the rest of the manufacturer's product line. Your standard catalog number should be formatted in this general format: XXX-X-*-XX-*

The "X" represents the manufacturers' codes which are separated by dashes, unless explicitly displayed otherwise. The catalog number should represent significant and unique attributes that do not cause the spawning of multiple unnecessary records, as defined by eLumit entry standards. "*", or asterisks, represent insignificant options we do not catalog/differentiate between product records, as defined by eLumit entry standards. With two or more insignificant options resulting in multiple successive asterisks, one will suffice. Therefore *-XXX-X-*-*-XX-*-*-* Can be represented as XXX-X-*-XX-*. Note that the first leading asterisk can be dropped altogether.

You may also include identifying terms like product line names, as shown here: Name XXX-X-*-XX-*

This should be used only when there are multiple named products within a single spec sheet. If the spec sheet contains an overall name that is captured in the Spec Sheet name the product name should not be added included.

The ultimate goal here is to create a clearly identifiable catalog number with an obvious logic.

See MD4-20 / MD420 (Cooper Portfolio) for catalog reference.

Product Type

If there is any decorative piece on the fixture check decorative. If the fixture has a functional lighting purpose, specify architectural.

Source Attributes (Lamping)

Select the appropriate lamp source type, quantities. See lamping for further lamp help.


Ballasts are used for HID and fluorescent lamps only. Transformers are for low voltage halogen and incandescent lamps. Any spec sheet showing ballasts or transformers associated with lamps different from the above specified lamps are wrong. LED Drivers are for all LEDs and will show up as transformers on the public site after entry.

Ballast/Transformer Location: Integral means the ballast or transformer is in the fixture. Remote means it is separate from fixture. The type should be specified in spec sheet. Select ‘electronic or magnetic’ for fixtures explicitly naming both as an option. Xfmr Voltage step: Select only for transformers. The actual step down in voltage should be explicitly called out. Core and Coil is a technology which means magnetic.

Dimensions and Adjustability

The dimensions of a fixture give specifiers an idea about the overall size and are useful in filtering out fixtures that are too large, particularly with recessed downlights and accent lights.

If a fixture has a circular dimension it is appropriate to enter the fixture with a diameter in lieu of width or depth. For fixtures that have diameters, you must enter diameter in the diameter area. Only height and width will not suffice as elumit will think it's a continuous run fixture and show that the length varies. When you specify diameter, eLumit does not look for a length.

  • If you enter H and W only, it means that the fixture only has height and width and length is open (like in a continuous run fixture).
  • If you enter H and L only, it is still a fixture with a negligible or unspecified width (rare).
  • If you enter H and D only, it means the fixture is circular.
  • If you enter H, W and D, it means that the fixture has a height, has a circular portion which is denoted by the diameter, and also a third dimension (width), possibly for another part of the fixture that is not circular.


The standard, simple listings

ARL Listed, IBEW, Chicago plenum, and UL Class I and Class II are typically straightforward. If the explicit listing is mentioned or the following logos are used, select the appropriate label. Other labels may not be so straightforward.


Explicit text or images are sufficient to give a product record the relevant listing. If a product is UL listed for Wet locations, do not also select UL listed for Dry or Damp locations, unlike the environment check boxes. The reason is that check the top level listing results in the optimal presentation and is the most accurate representation of the actual label. Environment labels need to be explicitly called out for thoroughness and searchability. UL1598 is the same as UL listed.

The statement as to listing for wet, damp and dry environments should be explicit, and if there is doubt that the environment applies to a specific listing, it should not be assumed to apply. For example, it is correct to assume the following statement applies wet approval to both UL and CUL: "UL, CUL approved for wet...". It is not desirable to make the same assumption about this statement: UL approved for wet conditions. CUL".


IBEW is the label given to products made by members of the Internation Brotherhood of Electrical Workers union. Certain projects required that only products with appropriate union labels be allowed installation. This label qualifies products for those projects. An IBEW label means the fixture is NYC approved.

IC rated

Select this check box whenever a fixture is specified as "IC" or "IC rated". IC stands for Insulated Ceiling and represents that the fixture is qualified for installation in insulated ceilings, typically referring to adequately sealing the fixture and managing the heat so the surrounding insulation is not a fire hazard. Sometimes a product will be listed as "Non-IC" which may denote that there is an IC option either within the same spec sheet or within the same series.


Options are selected similarly to Labels. In most cases if the option is mentioned on the spec sheet, you select it.

277:12V transformer

A transformer that reduces the voltage from 277 Volts to 12 Volts, which should be the operational voltage for the fixture.

277:120v transformer

A transformer that reduces the voltage from 277 Volts to 120 Volts, which should be the operational voltage for the fixture.

347V Ballast

Air-handling capability and Return air plenum

These two sound similar but are different and may cause confusion. Air handling capability refers to the ability to handle the air supply and return it. Return air plenum handles air return only.

Auxiliary quartz standby

Provides light after a momentary power interruption to HID lamps.

Cord and plug

Insulated electrical cable with a plug which can be inserted into an electrical receptacle.

Chicago plenum

For a fixture to qualify as Chicago plenum (required for all fixtures that will be installed in the City of Chicago) the fixture is to be installed in the space between the finished or suspended ceiling. It must have special gasketing to completely enclose the junction box, splice compartment or wireway to avoid electrical sparking, fire or other other hazards. <ref>"Chicago Plenum"</ref>

Decorative accessories

Optional add-on pieces which changes the appearance of a fixture giving it a decorative look.

Dimming ballast

This optional device has the ability to lower the brightness of a fixture by reducing the amount of power going to the lamp.

DMX control

Connects to a DMX controller, a computer with software that emulates DMX controllers or a DMX network. Is capable of movement, dimming and/or other special affects.

Duplex receptacle

Electrical outlet with space for two plugs. <ref>"Duplex receptacle"</ref>

Earthquake mounting hardware

Electronic dimming ballast

An electrical ballast with characteristics of a dimming ballast, which is the ability to electronically dim the lamp it is connected to.

Electronic ballast

Electronic ballasts uses a printed circuit board with semi-conductor technology to electronically regulate the voltage that starts and runs the lamp. Electronic ballasts can also operate at a higher current frequency range and send a more precise and efficient flow of voltage through the lamp. Some electronic ballasts include all electronic components, while some include a mix of electronic and magnetic components. <ref>"Electronic Ballast"</ref>

Emergency ballast and Emergency battery pack

An emergency ballast option shows that the fixture is hardwired for an emergency circuit. Emergency options, if not explicitly called out, tend to be for emergency ballasts. If the emergency option is noted with dimming or other ballasts, that means the emergency feature is likely an emergency ballast. Any emergency option citing a time limit most likely contains a battery. Emergency batteries must have indicator lights and a test switch, though these features are not always mentioned. However, if they are mentioned, it is a substantial clue that the emergency option refers to a battery. Sometimes the term "emergency" isn't mentioned; unless the fixture is portable, any mention of batteries is sufficient reason to select this option. An emergency ballast and emergency battery pack option can both be available but it is rare.

Electronic Transformer

Fire-rated ceilings suitability

Framing Projector


Noted as Fuse, Fuse 120, Fuse 277, Fuse Kit, Fusing etc. Fusing is an option that shows a fixture uses an integral fuse to protect the fixture.

GFCI receptacle

Ground Fault Circuit Interrupter is a receptacle with a safety feature. Once it detects any sort of electrical imbalance (e.g. if water were to get into the receptacle or overloading of the receptacle), it shuts off the flow of electricity preventing short circuiting, power surges, electrocution and other but not all damages. Once the safety feature trips, the receptacle has a reset switch that will allow normal flow of electricity again unless there is still a imbalance present.

HID instant restrike

HID lamps have an arc tube inside which consists of both gas and metal salts. The gas is used as the initial strike for the tube. Once the gas gets hot enough, it evaporates the metal salt creating plasma which increases the intensity of light and lowers the power consumption. If the lamp is not hot enough from previous use, the HID instant restrike relights the lamp so it is operational but does not have to go through the initial warm up phase. The restrike is usually a smaller, halogen lamp of lesser power which accomplishes this. Some spec sheets will describe the lamp, others do not. This accessory is frequently called "Quartz Restrike" on manufacturer spec sheets. <ref>"HID instant restrike"</ref> <ref>"HID lamp"</ref>

Integral Dimmer

Magnetic Ballast

Also called an electromagnetic ballast. These are the most basic and oldest type of fluorescent ballasts. The basic construction consists of a core of stacked steel plates wrapped with a coil of copper or aluminum wire (a basic electron magnet). This is then potted in an insulating material such as asphalt to conduct the heat of the ballast outward. The entire assembly is then put into a metal housing to prevent breakdown and shock hazard. Usually a separate starter of various different designs is incorporated into this housing to provide the additional voltage needed when initially starting a fluorescent lamp.<ref>"Magnetic Ballast"</ref>

New York City Construction

Similar in concept to the IBEW label, products that are NYC approved or have an option for New York City construction represent products that can be used in projects that demand this restriction. Look also for "New York City Code" or "NYC Code".

New York Calendar is NOT the same, and does not qualify for the New York City construction option.

Optical accessories

Optional add-on lenses, filter and anything to change or alter the original way a fixture distributes light. Also referred to as "optical elements".

Photocontrol capability

Remodeler housing

Remote Transformer Housing

RFI filter

Radio Frequency Interference Filter, sometimes seen as Radio Interference Filter or RIF filter.

Sloped ceiling adapter

An adapter piece for fixtures that will be installed in sloped ceilings but is designed primarily for horizontally flat ceilings.

Synch control

Tamperproof hardware

Hardware for a fixture, usually on the exterior and is meant to withstand being tampered with.

Vandal-resistant options

Fixtures with rugged housings, break-resistant type shielding, and tamper-proof screws.<ref>"Vandal-resistant options"</ref>

Washington State Airtight Approval

No options

No available options provided.

IP Listing

An index indicating the protection of persons against access to hazardous parts and protection of equipment against foreign solid objects and ingress of water. The IP listing consists of up to 2 numbers following the letters IP. For a chart decoding possible IP listings click here: Note that it is possible for a fixture to have more than one listing. In that case enter one listing in the dropdown menu and note the other in the eLumit Notes section.


Select the appropriate environments shown in the spec sheet. If a fixture is suitable for a wet environment, select Dry, Damp and Wet. If a fixture is suitable for a damp environment, select Dry and Damp. All other environments must be called out explicitly in the spec sheet; for example, a submersible fixture is not necessarily suitable for a marine environment.


Related Equipment links feature a text box and URL box. The Text box gets your URL title, and the URL gets the URL, obviously. Related Equipment links should be filled with links to Accessory pages (Trims, Frame-In kits, housing, optical accessories, etc). At times manufacturers will provide links to instruction sheets for special variations of the product (IC Housing, Chicago Plenum, optional mounting) and they should be entered here. As sometimes happens, if more links are provided than the product record will support, choose what seem to be the most significant links.


eLumit search relies increasingly on keywords. The following three fields collectively should capture of all relevant keywords thoroughly. The source of keywords comes primarily from the spec sheet but other sources may include catalog pages, brochures and the products web page. These sources should be included especially if significant keywords regarding applications or fixture types are mentioned; these keywords represent the primary way in which the manufacturer expects their products to return in searches.

eLumit Notes

eLumit notes aim to capture important information for the specifier that is not already captured by the rest of the entry page. Reference the spec sheet as well as the product web page for information. The information is usually technical, and can include available lighting distributions, a brief list of optional optical accessories, and a note that fixture dimensions vary for optional housings and accessories. Listings not provided for elsewhere in the product entry site, such as IDA Dark Sky friendly, an additional IP rating should be entered here. The entry in this section should not exceed the length provided in the entry location.

Manufacturer's Notes

Manufacturer notes aim to capture marketing text. The ideal text in the common introductory paragraph at the beginning of the spec sheet, brochure or product web page. This text often includes brand names and company specific terms for technology, methods or systems used. Another set of ideal text revolves around applications of the products. Manufacturers will often cite how a product is used in specific spaces or in various ways. Their attempt here is to broaden the potential market for their product so as not to exclude it's use in projects. Capturing those terms will help in the searchability of a product. This section can also be used to list fixture attributes for which there was not room in eLumit Notes. Obvious advertising superlatives such as "efficient" and "superior" should not be entered.

IES Notes

Once one or more IES files have been selected for a product, there's a space under the IES description for "eLumit Notes". In this field, manufacturers want descriptions of the IES for example the lamp wattage used, the beam spread and any type of accessories like frosted lens, spread lens and if it's asymmetric or symmetric. You should be able to find all this information within the IES file itself in the description. If the description has the type of test and specific manufacturers' lamps, it should be included as well.

Keywords to add

solite lens

Hidden Keywords

This field is useful as a means to have products return in certain keyword searches that are not readily apparent to the specifier. You may enter keywords that are present in the spec sheet in alternate tenses, number and spelling.

Fixture Type Attributes

Product Records also need properly formatted Images.

Rectilinear Lens

Delete Product

When deleting products, sometimes the product is archived and will continue to show up on the admin site. Once you're sure you've gone through the process of deleting a product but it is archived, search for the product on the public site the next day. It should be deleted.

Additional Terms to Define

Solite lens

Dimming Advance Mark X





Class P, HPF, program start


The aperture is the area or hole from which light escapes the fixture. If the aperture is circular, the aperture dimension is the diameter. If the aperture is rectangular, the aperture dimension is the larger of the two rectangles dimensions.

Entering Product with Multiple Spec Sheets

Some manufacturers, notably Lightolier, require catalog numbers of products to include nemonics for 2 or more of the following: fixture, housing, trim, reflectors and frame-in kits.

Choose the spec sheet that provides the most information required to create the product record, first and foremost the type of fixture the record describes. The prominence with which the company's web site displays the trim or housing in the particular series can be helpful in making this choice.

For example, Lightolier's Calculite ProSpec PB1T6 Downlight requires specification of the fixture and 1 of 3 reflectors in the catalog number.

Note that the spec sheet contains all the information necessary to enter the associated product records. Under the diagrams, under the heading "Ordering Instructions", the company states 1 fixture (described in the spec sheet above) should be ordered with 1 of 3 reflectors, and it lists them. As an example, the spec sheet for MHT6RS is below:


None of the information contained in this spec sheet is necessary for creating a product record. The primary purpose of these 3 reflectors is to define the light distribution of the fixture, which is normally not critical data for eLumit's records (See the entry for Fixtures - Floodlights in this Wiki).

To satisfy the company's ordering instructions and meet eLumit's requirements, the fixture spec sheet was entered as the product spec sheet. 2 records were created with catalog numbers PB-1-T6-39-*/MHT6R* and PB-1-T6-70-*/MHT6R*. The reflector spec sheets were listed, with their url's under "Related Equipment" on the product record.

A Counter-Example

Lightolier's Uniframe series also requires specification of trim and housing ("frame-in kit" in this instance). This example can be found in the eLumit public site searching the catalog number 1001H*/1001F13U Q.

The Trim spec sheet


The Frame-In Kit spec sheet:


The Trim spec sheet was entered as the fixture spec sheet for the following reasons:

Company Presentation:

A search for Uniframe on the Lightolier web site yields the following result:

Note that the company presented the trims in greater detail.

Complete Fixture:

Both the trim and frame-in kit spec sheets specify that the complete fixture consists of frame-in kit and trim.

Type of fixture: the trim defines fixture type: downlight, wallwash etc. The frame-in kit spec sheet does not.

Completeness of Spec Sheet:

All the data critical to creating a product record is on the trim spec sheet: catalog number logic, lamping information, dimensions. The frame-in kit spec sheet does not define fixture type, and is missing a critical dimension, that is fixture height/depth. The frame-in kit spec sheet does contain important information however, such as electrical (ballast) and fixture length and width, and should be appended to the product record as Related Equipment.

Known Issues

Period/Decimal Point (.) in Watts field

Do not enter (.) in the watts field. The database does not know how to handle the decimal and the public search will break. Round up for wattage. "5.3" gets "6".

Cooper Description causing Run Time errors in copying

Some old Cooper products with the Cooper Description filled out (at the bottom of the entry page under Cooper Specific) have some characters that may be preventing records from being entered or modified. As a workaround, just clear the Cooper Description field (which is no longer in use).
