LED Fixtures Attributes

An LED fixture is a luminaire with an integral LED source and driver, sold by electrical and lighting distributors to contractors, plant and facility engineers, ESCOs, and the specifiers who lay a job out before anyone quotes it. The category spans high bays, troffers, linear ambient, wall packs, area and roadway heads, floods, downlights and retrofit kits.

The data is hard because the datasheet is not a product — it is a configurator. One PDF covers a family, and hundreds of catalog numbers are built by concatenating wattage, CCT, voltage, distribution, finish and controls from an ordering matrix. Performance for each combination lives in LM-79 tables and .ies files, not in the copy. Field-adjustable fixtures compound it: one physical SKU with three wattages and three CCTs has nine performance states, and most schemas hold one value per field.

Then the standards move. DLC retires Technical Requirements versions, and a fixture qualified under a retired one drops off the QPL — the rebate the buyer is counting on disappears while the SKU sits unchanged in the catalog.

Core

Every SKU needs these. Without them the record is not a product, it is a row.

Manufacturer Part Number (MPN)
identifier
ALED4T105SFNW/480/D10/7PR

The catalog number is the ordering code — it encodes wattage, CCT, voltage and options. Buyers and agents quote from it; it must match the supplier exactly.

Luminaire Type / Primary Use
enum
High Bay Luminaire (Commercial & Industrial)

Splits the catalog into the trees buyers shop. DLC's Primary Use Designation also decides which efficacy threshold the fixture is judged against.

Delivered Lumens
number · lm
13,204 lm

Fixture-level output per LM-79, not LED-package lumens. First number a buyer filters on and what the photometric layout is sized from.

Input Wattage
number · W
105 W

System watts at the driver input, including driver losses. Drives circuit loading, rebate math and metal-halide equivalence claims.

Correlated Color Temperature (CCT)
enum · K
4000 K

Buyers filter it before anything else and jobs standardise on one value. Must sit inside an ANSI C78.377 nominal quadrangle, not just be a printed number.

Input Voltage
enum · V
120-277 VAC

Decides whether the fixture lands on the site's panel. 120-277 V universal and 277-480 V are different SKUs and cannot be substituted at install.

Mounting Type
enum
Slipfitter, 2-3/8 in tenon

Determines what ships in the carton and whether it fits the existing pole, tenon or ceiling grid. A slipfitter head will not go on a trunnion bracket.

GTIN-12 (UPC)
identifier
00762148765431

Required by marketplaces and the electrical data pool for item matching. Without it the SKU cannot be listed or reconciled against a supplier file.

Country of Origin
enum
CN

Drives tariff classification and Buy American / BABA eligibility on federal and utility-funded work — a hard gate on many lighting retrofit bids.

Differentiating

What buyers actually compare on. This is where catalogs win or lose the filter.

Luminaire Efficacy
number · lm/W
122.1 lm/W

Delivered lumens over input watts. The rebate gate and the energy-code calc. DLC V5.1 sets 120 lm/W for high bay, 110 for troffer, 105 outdoor.

Color Rendering Index (Ra)
number
80 Ra (R9 ≥ 0)

Retail, inspection and food-prep jobs spec 90 CRI; warehouse aisles accept 70. R9 matters wherever reds must read true.

Light Distribution (IES Type)
enum
Type IV (Forward Throw)

Type II-V and forward throw decide pole spacing and whether light lands on the neighbour's property. Wrong type means a failed photometric layout.

Dimming Protocol
enum
0-10V, dims to 10%

0-10V, DALI-2 and phase-cut are not interchangeable. Tying a 0-10V fixture into a DALI system needs a converter the quote didn't include.

L70 Lumen Maintenance
number · h
100,000 h (TM-21)

Hours until output falls to 70% of initial, projected per TM-21 from LM-80 data. Rebate forms ask for it; "50,000 hours" with no basis won't clear.

Compliance & identifiers

Standards, regulatory data, and the identifiers channels reject you for missing.

Safety Listing & Location Rating
enum
cULus per UL 1598, Wet Location

The AHJ inspects for the mark and the damp/wet designation. A dry-location fixture under a canopy fails inspection regardless of its IP number.

Ingress Protection (IP) Rating
enum
IP66

Sealing against dust and water jets. Distinct from the UL location listing — washdown and outdoor buyers filter IP65/IP66 specifically.

DLC Qualification & Product ID
identifier
DLC Premium — PK81GPQ7

Utility rebates are paid against the DLC Product ID, and Standard vs Premium changes the amount. Listings lapse when a TRT version is retired.

Warranty Term
number · years
5 years

DLC requires a minimum 5-year warranty covering the complete luminaire — driver, LEDs, housing, optics and finish. Component-only warranties don't qualify.

The fields that aren't in the schema at all

What most led fixtures catalogs are missing.

The table above is the schema most catalogs already have. These are the attributes that usually aren't in it — each one surfaced by a signal from the live market rather than by an audit of what's already there. This is what Anglera's Schema Foundry does on a real catalog, in this category.

Supplier signal
+ BUG Rating (IES TM-15)

DLC requires every outdoor luminaire on the QPL to report a 6-character BUG value and manufacturer spec sheets print it, but it lands in the PDF only — no B/U/G field exists on the record to filter.

Dark-sky and municipal glare ordinances are written in BUG terms. Quoting a G3 where the spec says G2 loses the submittal, or forces a re-order after install.

Marketplace signal
+ Field-Adjustable Wattage & CCT

Marketplace listings carry titles like "60-80-100W, 4000-5000K" — the settings are stuffed into the product name because the record holds one wattage and one CCT, not a set.

A selectable fixture indexed at its top wattage never appears in a 60 W filter. Teams work around it by cloning a SKU per setting, and the clones drift apart.

Competitor signal
+ Controls Receptacle / Sensor Interface

Competitor rails expose a "controls ready" facet for 7-pin (ANSI C136.41) receptacles and Zhaga Book 18 sockets; most catalogs collapse the whole controls story into a "Dimmable: Yes" boolean.

Networked-controls retrofits stall at commissioning when the fixture has no receptacle for the node the job specified — the node ships, the fixture can't take it.

Search signal
+ Photometric File (.ies, ANSI/IES LM-63)

Specifiers run the layout in AGi32 or DIALux before they buy and search for "<part number> ies file"; distributor PDPs link to a family PDF that doesn't map to the SKU, if they link at all.

The specifier leaves for the manufacturer's site to get the file, builds the layout around whatever they find there, and the RFQ never comes back.

Review signal
+ Maximum Ambient Temperature (Ta)

Reviews of high bays in unconditioned warehouses report early driver failure; Ta is on the datasheet — commonly 40 °C or 50 °C — but rarely reaches the catalog record.

A 40 °C fixture sold into a 45 °C plant derates and fails inside warranty. The return is freight-heavy and the warranty claim is contestable.

How Schema Foundry finds these

Messy in, governed out.

The same value, spelled every way lighting suppliers spell it. A filter only works once they agree.

Correlated Color Temperature (CCT)
4000K4000 K40K840Neutral WhiteCool White
4000 K

Suppliers genuinely disagree: some call 4000 K Neutral White, others Cool White. ANSI C78.377 nominal bins settle it; the words never will.

Input Voltage
120-277V120/277VMVOLTUNVUniversal120~277VAC
120-277 VAC

MVOLT and UNV are brand shorthand for the same range. Left as free text, a 277 V site search misses every fixture that would have worked.

Light Distribution (IES Type)
Type 4Type IVT4Forward ThrowFTType IV Medium
Type IV (Forward Throw)

Roman numerals, Arabic numerals and nicknames for one distribution. The area-light filter rail is noise until they are merged.

Ingress Protection (IP) Rating
IP-65IP 65IP65Wet LocationWeatherproof
IP65

"Wet Location" is a UL 1598 listing, not an IP number. Suppliers drop both into one field; they are separate claims and must be split.

What buyers ask

Every one of these should be answerable from the attributes above. If it isn't, that's a gap.

  • Is this DLC Premium or just Standard? The rebate on this job only pays on Premium.
  • Does it dim 0-10V, or do I need DALI-2 to tie into the building control system?
  • Will this run on 480V, or is it 120-277 only? The panel on this site is 480.
  • What's the BUG rating? The ordinance on this parking lot caps uplight at U0.
  • Is it wet location listed, or just IP65? The AHJ wants the UL listing, not an IP number.
  • 4000K or 5000K for a warehouse aisle — and what CRI am I actually getting?
  • The plant runs 45°C in August. What's the max ambient before the driver derates?
  • Can I get the .ies file? I need to run the layout in AGi32 before I quote it.

LED Fixtures data, in practice

Why isn't "Dimmable: Yes" good enough?

Because it answers nothing the installer needs. 0-10V, DALI-2 (IEC 62386), phase-cut/ELV and wireless nodes are different physical interfaces. A 0-10V fixture on a DALI job needs a converter; a phase-cut dimmer on a 0-10V driver does nothing or flickers. Separately, the fixture may carry an ANSI C136.41 7-pin receptacle or a Zhaga Book 18 socket for a control node — a different question again from the dimming protocol. DLC recognises this: products listed as dimmable are required to report their available wired and/or wireless control communication protocols, and to report whether integral controls are available. A boolean throws all of that away.

What does DLC qualification actually gate?

Utility rebates, and through them a large share of retrofit economics. The Technical Requirements set minimum efficacy by Primary Use Designation — under V5.1, 120 lm/W for high bay, 110 for troffer, 115 for linear ambient, 105 for outdoor — with Premium adding +15 lm/W. Every qualified product needs power factor ≥0.9, THD ≤20%, a minimum 5-year whole-luminaire warranty, chromaticity inside ANSI C78.377 quadrangles from 2200-6500K, and L70 evidence via LM-80/TM-21. Premium additionally requires continuous dimming and L90 >36,000 hours. Rebate paperwork is filed against the DLC Product ID, so that ID belongs on the record — not just a "DLC Listed" flag.

How should selectable-output fixtures be modelled?

As sets, not scalars. A wattage- and color-selectable wall pack at 60/80/100 W and 4000/5000 K is one orderable SKU with nine performance states, each with its own lumens and efficacy. Catalogs that hold a single wattage either pick one setting — and vanish from filters for the others — or push the settings into the title, which no facet can read. The workable model carries the selectable settings as an enumerated set, plus lumens and efficacy per state, with the shipped default recorded. This affects rebate handling too: DLC evaluates worst-case operating mode, so the qualifying efficacy is not necessarily the one on the marketing sheet.

Do we need both CRI and R9?

For anything past a warehouse aisle, yes. Ra averages eight pastel test colors and says nothing about saturated red, which is exactly what fails in retail, food prep and inspection work. DLC Standard requires Ra ≥80 with R9 ≥0 for indoor products, and relaxes to Ra ≥70 for outdoor and high-bay — where R9 ≥-40 applies to high-bay and outdoor products must report R9 regardless. Efficacy allowances are available for higher color rendition, so the values carry commercial consequences, not just aesthetic ones. TM-30 metrics (Rf, Rg, Rcs,h1) are reported alongside and are increasingly what specifiers ask for by name.
