Recessed downlights: sizing and beam angle basics
Recessed downlights look simple, but cut-out size and beam angle decide whether a space feels even or spotty. Importers who document these details get cleaner installations.
Cut-out and housing depth
Always list required ceiling cut-out diameter and available void depth. Shallow ceilings need low-profile housings; deep voids allow better thermal design for higher-output LEDs.
Fire-rated and airtight variants matter for some building codes. If the tender mentions them, flag the requirement early so manufacturing is not delayed.
Beam angle and spacing
Narrow beams (around 15–24°) highlight features; wider beams (36–60°) provide general ambient light. Spacing rules of thumb depend on ceiling height—share drawings when possible.
Adjustable gimbal downlights help when furniture layouts change. Fixed downlights cost less and pack denser for large housing projects.
Driver and dimming
Confirm trailing-edge, 0–10 V, or DALI requirements before ordering. Mismatched dimmers are a common site complaint after import.
NMF can align downlight families with compatible drivers so a project order stays consistent across phases.
