Note 01
Describe what the light should do
Use ordinary language first: mark an approach, reveal one planted edge, or support a wall-side transition. Name the viewing positions, operating moments and boundaries. This creates a brief without pretending that a beam label solves the site.
Reed has a shielded downward-aperture concept, Cairn an adjustable spot concept, and Lintel an underside-slot concept. None has a verified photometric distribution or a promised cutoff.
Note 02
Request configuration-specific data
Obtain the actual luminaire, optic, source, driver and control reference together. Ask for the appropriate photometric files, reports and product documentation from the real supplier. Check that their identifiers and revisions match the proposed item.
This demo does not generate IES/LDT files, lux maps, output figures, IP/IK marks or compliance certificates. A label on a concept sheet must never be substituted for a real test record.
Note 03
Test the site, not the picture
Use real geometry, materials, mounting positions and maintenance assumptions in a qualified lighting study. Then assess an appropriate physical mock-up and commissioning process. A convincing scene can still hide direct glare or omit a sensitive neighboring view.
Official industry references informed the question-led organization: BEGA’s bollard product structure separates mounting accessories and optical descriptions, while ERCO’s light-pollution overview explains why direction and context matter. Their product claims do not apply to VELT.
