KEY TAKEAWAYS
- IES listed a complete LP-8 revision for public review
- The review focuses on lighting and control commissioning
- Projects need documented control intent and acceptance criteria
- Manufacturers should provide testable system information
- Commissioning should be planned before installation
01What IES Announced
On 3 July 2026, the Illuminating Engineering Society listed BSR/IES LP-8-2x, Lighting Practice: The Commissioning Process Applied to Lighting and Control Systems, for public review.
IES states that the 2020 standard has been completely revised and that the review period runs through 31 July 2026.
02Why Commissioning Matters
Commissioning verifies that luminaires, drivers, sensors and controls are installed and operate according to the owner’s project requirements.
For increasingly connected lighting systems, this process also checks zoning, scenes, sequences and interfaces that cannot be confirmed from product specifications alone.
Key Industry Implications

01 Why Commissioning Matters
Commissioning verifies that luminaires, drivers, sensors and controls are installed and operate according to the owner’s project requirements.

02 Implications for Designers
Design teams should document control intent, expected performance and acceptance criteria early enough for commissioning providers and contractors to test them.

03 Implications for Manufacturers
Manufacturers can support commissioning with accurate wiring information, control compatibility data, photometric files, addressing instructions and fault-diagnostic guidance.

04 What Project Teams Should Do
Lighting professionals can review the official draft process and submit comments through the IES public-review channel during the stated period.
03Implications for Designers
Design teams should document control intent, expected performance and acceptance criteria early enough for commissioning providers and contractors to test them.
Clear schedules for aiming, scene setting, sensor calibration and functional testing reduce ambiguity at handover.
04Implications for Manufacturers
Manufacturers can support commissioning with accurate wiring information, control compatibility data, photometric files, addressing instructions and fault-diagnostic guidance.
Serviceable drivers and consistent firmware or configuration records also improve long-term operation.
Industry Update Review
| Topic | What to Verify | Project Relevance |
|---|---|---|
| Source | IES listed a complete LP-8 revision for public review | Projects need documented control intent and acceptance criteria |

05What Project Teams Should Do
Lighting professionals can review the official draft process and submit comments through the IES public-review channel during the stated period.
Even where the draft is not contractually required, current projects benefit from defining measurable commissioning steps rather than treating handover as a simple switch-on test.
