Technical project enquiries
Architectural lighting alternatives, reviewed against your specification
A successful alternative preserves design intent—not just appearance or wattage. Share the original reference, installation conditions and required performance. Any proposed configuration needs a documented comparison and acceptance by the responsible project team.
Evidence before equivalence
01
Potential option for technical review
Correct category, mounting and use; all known gaps disclosed.
02
Compared against stated project requirements
Signed comparison, exact configurations, photometry, drawings, controls, environment and warranty review.
03
Accepted for this project and revision
Named consultant/client acceptance, sample or mock-up where required, schedule and recorded deviations.
Electrical safety, mounting, environment and required approvals are stop conditions. No similarity score can compensate for a failed gate. No manufacturer affiliation, blanket equivalence or project acceptance is implied.
