UL 60335-2-107:2026 Adds New Tests for Smart Lighting

On June 9, 2026, UL released the final version of UL 60335-2-107:2026, adding two mandatory test items for smart lighting products exported to the US, including hotel guest room automation lighting systems. For manufacturers, exporters, testing coordination teams, and downstream buyers, the update matters not only because the rule becomes mandatory on December 1, 2026, but also because it adds documentation requirements during the transition period and is already associated with an average 4–6 week extension in delivery lead times.

What the final standard now requires

According to the information provided, UL issued the final UL 60335-2-107:2026 standard on June 9, 2026. The new requirements apply to smart lighting equipment and include hotel guest room automation lighting systems.

Two additional mandatory tests are specified: radiated RF electromagnetic field immunity under IEC 61000-4-3 Level 3, and LED module thermal runaway protection verification under UL 8750 Annex Q.

The new rule will become mandatory on December 1, 2026. During the transition period, products for export must provide both the legacy UL 1598 documentation and supplemental test reports aligned with the new edition.

The provided information also states that average delivery cycles for Smart Lighting manufacturers exporting to the US are extended by 4–6 weeks.

Where the pressure is likely to appear first

Export programs already in shipment planning

From an industry perspective, direct exporters are likely to feel the impact first because the update affects compliance documentation, test sequencing, and shipment timing. What deserves closer attention is the transition requirement to provide both the older UL 1598 basis and the new supplemental reports, which can complicate document preparation for products already moving through approval or booking stages.

Manufacturing and product readiness teams

Analysis shows manufacturers may be affected at the product validation and release stage rather than only at the final shipping stage. The added EMC immunity and thermal runaway protection verification introduce extra checkpoints that can delay model release, especially where export schedules depend on test completion before customer delivery.

Supply chain and fulfillment coordination

Supply chain service providers and order fulfillment teams may need to adjust around the reported 4–6 week lead-time extension. Observably, the main issue is not only transit planning but also whether compliance files, test reports, and delivery commitments remain aligned across production, inspection, and export handoff.

Buyers and project-side users

US-facing buyers, importers, and project users such as hospitality-related lighting purchasers may need to pay closer attention to model approval timing and document completeness. For projects with fixed installation windows, any mismatch between commercial delivery dates and updated compliance readiness could become a practical concern.

What companies should watch now

Separate confirmed requirements from internal assumptions

What deserves closer attention is the difference between the confirmed text and company-side interpretation. The confirmed facts are the two added tests, the December 1, 2026 mandatory date, the transition requirement for dual reporting, and the average 4–6 week delivery impact stated in the input. Companies should avoid building schedules around assumptions that go beyond those points.

Review affected product categories early

Manufacturers and exporters should first identify which smart lighting models fall within the stated scope, especially products tied to automation lighting applications such as hotel guest room systems. In practice, this helps determine where supplemental testing and documentation may need to be inserted into ongoing export workflows.

Recheck documentation and customer communication

During the transition period, the need to provide legacy UL 1598 materials together with new supplemental test reports makes document control a practical issue. Companies should pay attention to how compliance files are presented to customers, import-side partners, and internal sales teams so that delivery expectations match actual certification progress.

Build schedule buffers into US-bound orders

Given the stated 4–6 week average extension in delivery cycles, export teams may need to reassess quotation timing, production release dates, and shipment commitments for US-bound smart lighting orders. Analysis shows this is less about broad strategy and more about avoiding avoidable timing gaps in active projects.

How this update is best understood at this stage

Observably, this is not just a routine wording change in a standard citation. The addition of mandatory EMC immunity and thermal runaway protection verification points to a more specific compliance threshold for smart lighting products entering the US market.

At the same time, it is more appropriate to understand this as a near-term operational change with broader signaling value, rather than as a final indicator of wider market outcomes. The rule has a clear effective date and defined transition expectation, but the full commercial impact across product lines, customer acceptance processes, and shipment planning still needs continued observation.

Why the market should keep following it

The immediate significance of this development lies in execution: new test items, dual-reporting requirements during transition, and longer lead times for US export business. For companies active in Smart Lighting, the issue is less about headline impact and more about whether internal compliance, delivery, and customer-facing processes can adjust in time.

It is more appropriate to understand this update as a concrete compliance change with short-term operational consequences and longer-term signaling for product qualification expectations in the US market. Further developments remain worth monitoring, especially any later clarifications in official wording, implementation practice, or reporting expectations.
