UL Listing Service
At Lamptouch we guarantee that your custom lighting not only looks exceptional but also complies with rigorous safety standards. Our UL Listing process ensures each fixture is evaluated, tested and labeled for safe installation in residential, commercial, and hospitality projects across the United States.
Note: Information below is educational and not legal advice. Final approval always depends on the Authority Having Jurisdiction (AHJ) and site conditions.
What is UL Listing & Why it Matters
UL (Underwriters Laboratories) is an independent safety organization. A UL Listed luminaire has been tested against recognized safety requirements and is suitable for the specified environment. Listing helps avoid project delays, protects your brand, and gives peace of mind to owners and insurers.
Our Process
1) Engineering Review
Design, wiring method, strain relief, creepage/clearance, enclosure & accessible parts review.
2) Component Compliance
We use UL components (sockets, wire, drivers, strain reliefs, connectors, junction bars).
3) Safety Tests
Ground continuity, polarity, dielectric/insulation checks, load & temperature checks, labeling review.
4) Label & Docs
We apply the compliance label and provide a test summary & care / relamping instructions.
Learn the Essentials
UL vs ETL vs CSA
These are Nationally Recognized Testing Laboratories (NRTLs). They test to the same safety requirements; acceptance depends on the AHJ.
Dry, Damp & Wet
Fixtures are rated for environments. The wrong rating can cause failures, rust, or rejection by inspectors.
Class 2 LED Circuits
Limited-power outputs commonly used for LED strips & miniature lamps. Great for safety and code simplicity.
Max Wattage & Relamping
Every luminaire needs clear limits. Over-lamping or wrong lamps can overheat components.
Grounding & Polarity
Metal parts must be bonded; live parts must remain isolated. Proper polarity prevents exposed shells from being energized.
Junction Box & Weight
Ceiling/wall mounts require appropriate boxes, support hardware and weight ratings.
Drivers & Dimmers
TRIAC/ELV/0-10V/DALI—compatibility matters. We match drivers and controls to your project voltage.
Portable vs Fixed
Table/floor lamps vs hardwired luminaires follow different requirements and marking conventions.

FAQs
Yes—most of the time. We evaluate wiring, insulation, sockets, enclosures, and strain-relief. We replace or add parts as required and apply the label when the unit passes tests. Some fixtures with inaccessible or unsafe construction may require redesign.
No, We don't provide this service on-site.
ETL (Intertek) is also an NRTL and tests to the same safety requirements. Most AHJs accept UL, ETL, or CSA marks. Always confirm local preferences with your inspector.
Small rewires are often 3–7 business days. Complex custom builds, drivers, dimming or wet-location upgrades can extend timelines. We’ll confirm after the engineering review.
Applied label with ratings, job reference/serial, test summary, relamping/maintenance instructions, and invoice referencing the labeled unit(s).

Request UL Listing ServiceUL vs ETL vs CSA (NRTLs)
UL, ETL (Intertek), and CSA are Nationally Recognized Testing Laboratories that evaluate and mark products that meet safety requirements. While the marks differ, the purpose and safety criteria are equivalent: electrical safety, construction, temperature, markings, and use tests.
- UL Listed: End product evaluated for a defined use/environment.
- UL Recognized: Component intended to be used inside a Listed system (e.g., drivers, sockets).
- ETL/CSA: Alternative NRTL marks widely accepted. Final acceptance depends on the local AHJ.
Dry / Damp / Wet Locations
- Dry: Indoor locations with no significant moisture. No direct condensation or splashing.
- Damp: Occasional moisture or condensation (bathrooms, covered porches). No direct water contact.
- Wet: Direct exposure to rain or jets. Requires gaskets, sealed entries, and suitable materials.
Selecting the correct rating prevents corrosion, failures, and inspection rejections.
Class 2 LED Circuits
Class 2 circuits limit voltage and power to reduce shock and fire risk. Common for LED strips and low-power modules. They typically require a Class 2 driver and segregation from line-voltage wiring.
- Supports longer runs and multiple points of light safely.
- Works with 0–10V / TRIAC / ELV depending on the selected driver.
- The AHJ may require service access to the driver.
Max Wattage & Relamping
Every luminaire must specify maximum lamp type and wattage. Exceeding the limit can overheat wiring, sockets, or diffusers.
- Prefer LED equivalents to reduce thermal load.
- Maintain ventilation paths and enclosure clearances.
- Do not alter socket type without re-evaluation.
Grounding & Polarity
All accessible metal parts must be bonded to ground. For Edison-base lamps, correct polarity keeps the exposed shell at neutral potential.
- Secure ground connections with listed screws/nuts or clips.
- Provide strain relief for flexible cords.
- Maintain required spacings/insulation between live and accessible parts.
Junction Box & Weight
Fixed luminaires must attach to an appropriate junction box with listed hardware. Heavier units may require weight-rated boxes/bridges or structural support.
- Include estimated fixture weight in your submission.
- For sloped ceilings or fragile plaster, plan additional bracing.
- Use listed mounting bars and fasteners.
Drivers & Dimmers
Common dimming methods include TRIAC/MLV/ELV (line-voltage), 0–10V (low-voltage control), and digital systems (e.g., DALI). Compatibility depends on the LED driver and project voltage (120/277V).
- Define the control type before assembly.
- For long LED-strip runs, prefer 0–10V or multiple drivers.
- We test for flicker and useful dimming range.
Portable vs Fixed Luminaires
Portables (table/floor) use cord-and-plug, a switch, and strain reliefs. Fixed (ceiling/wall) units connect to a junction box and may require bonding, mounting bars, and environmental ratings.
Converting a portable design to fixed (or vice versa) changes the requirements and markings; we will assess any redesign needed.
