The submittal says UL Listed and the certificate says UL 8750. For a 24V LED strip on a cove job, that certificate describes the LED parts. The strip as a low-voltage lighting system is normally listed to UL 2108, and a finished fixture is a UL 1598 product. So ask first which standard the listing is to.
Neither paper is wrong. A UL 8750 certificate is the right paper for a driver or an LED board, and UL 8750 sits inside the other two standards. It just does not answer the question about the strip run. This guide sorts the three standards by product form, then covers who decides whether a listing is required and what to check in the submittal.
Three Standards, Three Product Forms
UL files lighting products by standard and by category code. The table uses UL’s own lighting page for the codes and the standards’ published scopes for the coverage.
| Standard | What it covers | UL category | Typical product on a strip job |
|---|---|---|---|
| UL 2108 | Low-voltage lighting systems for installation under NEC Article 411 | IFDR | LED tape light and low-voltage luminaires sold as a system |
| UL 8750 | LED equipment used in lighting products: modules, arrays, packages, drivers, controllers | OOQA2 (modules, arrays), OOQL2 (packages), FKSZ (power supplies), FLTJ (controllers) | The LED board inside a product; an LED driver |
| UL 1598 | Luminaires for non-hazardous locations | IFAM (direct-mount), IFAO (recessed) | A finished linear fixture with its own housing and connection |
UL adds a note on that page that its standard assignments are examples and can differ with product specifications. So the table tells you where to start asking, not what a given reel carries.
UL 2108: The Strip as a System
UL 2108 is the standard written for the case this guide is about. Its scope applies to systems “intended for installation in accordance with the National Electrical Code, NFPA 70, Article 411.” It covers power units with output limited to 25 A, plus Class 2, exposed bare conductor, power-over-Ethernet and other low-voltage luminaires. The edition in force is Edition 2, and UL’s standards store shows a revision dated September 27, 2024.
Two lines in the scope matter to a contractor. First, LED components, controls and subassemblies inside the system must also meet UL 8750, so a UL 2108 strip already carries UL 8750 parts. Second, the standard does not cover lighting that other standards cover, such as UL 153, UL 1574 and UL 1598, and it names cord-and-plug luminaires, track-mounted luminaires, hand-carried luminaires and luminaires integrated with a power unit as outside its scope.
It also leaves out specialized applications: hazardous locations, emergency lighting, marine lighting, horticultural systems and germicidal luminaires. A UL 2108 mark on the reel does not settle a ship, a grow room or an exit-path job.
The scope text we reviewed gives no numeric voltage limit; it ties the power unit to the shock-risk voltage levels defined inside the standard. The familiar 30 V (42.4 V peak) figure comes from the NEC Article 411 definition of a low-voltage lighting system, according to IAEI Magazine’s explanation of that article. Check the definition in the NEC edition your jurisdiction has adopted.
UL 8750: Parts, Not Systems
According to Intertek, UL 8750 is the safety standard for LED equipment used in lighting products, covering modules, arrays, drivers and the associated electronics. It addresses the internal LED components of a product, “not the complete fixture itself.” Intertek lists the Second Edition as current, with its latest revisions published August 1, 2024.
UL 8750 shows up inside the other two standards. UL 2108 sends the LED parts to it. Intertek says UL 8750 “is used in combination with UL 1598” for luminaires. That is why a certificate naming UL 8750 is common, and why it proves less than it looks like. It tells you the LED equipment was evaluated. It does not tell you which end-product standard the strip or fixture was listed to. On a submittal, that makes it a good paper for the driver and a poor paper for the strip run.
A driver is the clearest example. A driver evaluated to UL 8750 is an LED power supply, but its output is Class 2 only if the Class 2 limit is also met and marked. We walk through that label reading in our Class 2 driver guide.
UL 1598: When a Strip Becomes a Fixture
UL 1598 is the luminaire standard for non-hazardous locations. Intertek describes it as covering recessed, surface-mounted and suspended fixtures, and it says the standard covers both low-voltage and line-voltage luminaires. The current version is the Fifth Edition, last revised January 31, 2024.
That is where the overlap comes from. A strip built into an aluminum housing with a diffuser, its own mounting and its own electrical connection is a luminaire. The LED board inside is a UL 8750 component; the finished fixture is a UL 1598 product. A bare reel sold to be cut, wired and mounted by the installer is, in practice, the UL 2108 case.
A strip with a power unit built in is the awkward middle. UL 2108’s scope lists luminaires integrated with a power unit as outside it, so the paper for that product should name another standard. Which one is the lab’s determination, so ask the supplier to name it.
Listed as a System or Built From Listed Parts
Commentary on Article 411 describes two routes. The first is a lighting system listed as a complete system. The second is a system assembled from listed parts: a low-voltage luminaire or strip, a Class 2 power supply, fittings and a listed secondary cable. Which route your edition allows is written in the adopted text, and our NEC guide for LED strip systems covers how to find that edition.
Electricians in Mike Holt Forum threads agree on one thing. The Class 2 power supply is the part that has to be listed and marked, and the cable should read CL2 or CL3, not only CM. Those threads are several years old and they are forum readings, not code text, so use them as questions to put to your inspector.
Does the Inspector Require It?
Whether a listing is required on a given job is a code and AHJ question, not a product one. The sources disagree. Some vendor pages say the NEC requires listing for low-voltage lighting. Others conclude that LED strips are not subject to it. In the forum threads, one answer puts it plainly: if the product has not been listed, accepting the installation is up to the AHJ. Another notes that some inspectors want everything, even plug-in items, listed by a nationally recognized testing laboratory.
Plan for the listing to be asked for, even where the code text leaves room. On a commercial job, a failed inspection costs a second visit and sometimes a replaced run, and that outweighs the effort of buying a listed system. Then get the AHJ’s position on listing in writing before the order, and ask which marks they accept. The same question for UL and ETL is in our guide to UL Listed, UL Recognized and ETL Listed.
Submittal Check: What the Certificate Proves
Read the certificate for what it names, then ask the follow-up. This is the part most submittals skip.
| What the paper says | What it proves | What to ask next |
|---|---|---|
| “UL 8750” only | The LED equipment was evaluated | Which end-product standard covers the strip or fixture? |
| “UL 2108” with a file number | The strip is Listed as a low-voltage lighting system, if the file shows Listed | Does the file cover this model, this voltage and this location rating? |
| “UL Recognized” | A component for a Listed end product | What end product is it built into, and under what conditions? |
| “ETL Listed” | Intertek certified it to a named standard | Which standard, and does the AHJ accept ETL? |
| “UL Listed,” no standard named | Very little | Which standard, which category, which file number? |
| “Class 2” on a driver | The driver output is power limited | Is the driver itself Listed, and to what? |
A line you can copy into a spec section: provide the certifier’s name, the standard, the listing category and the file number for the strip and the power supply, and show that the exact model appears in the file. The contractor sends it before approval, not after delivery.
FAQ
Do LED strip lights need to be UL listed?
The answer sits with the adopted NEC edition and the inspector, not with the strip. Sources disagree on whether the code itself requires listing for low-voltage strip. On commercial jobs, plan for a listing and confirm with the AHJ before the order.
Is UL 8750 enough for an LED strip?
No, not by itself. UL 8750 covers the LED equipment inside a product. The strip as a system is a UL 2108 question, and a finished fixture is a UL 1598 question. A UL 8750 certificate leaves the end-product standard unanswered.
Is UL 2108 the standard for LED strip?
For a low-voltage strip sold as a system, it is the standard the listing is normally written to. UL’s lighting page files it under low-voltage lighting systems, category IFDR. Its scope excludes marine, horticultural, hazardous-location and emergency applications.
Is a strip with a built-in driver UL 2108 or UL 1598?
UL 2108’s scope lists luminaires integrated with a power unit as outside it. Such a product should carry paper naming another standard, often the luminaire standard. Ask the supplier which one and for the file number.
Where do I verify a listing?
Use UL Product iQ for UL file numbers and Intertek’s Directory of Listed Products for ETL marks. Look up the model, not only the company. Our UL Listed, UL Recognized and ETL Listed guide walks through the lookup.
What to Verify With the AHJ
- Whether the jurisdiction requires a listing for low-voltage lighting, and under which NEC edition.
- Whether the system must be listed as a whole or may be built from listed parts.
- Which marks they accept: UL, ETL or other recognized labs.
- Which location rating (dry, damp, wet) the listing must state. We cover that in what UL and the NEC require for wet locations.
- The documents they want on site: file numbers, certificates, datasheets.
