ROT/EXT-KITCHEN-TASK-LIGHTING

Description

Kitchen task lighting: every working countertop section needs undercabinet lighting (LED strips or pucks) providing > 50 footcandles (540 lux) at the work surface. The ambient ceiling light alone (typically 20-30 fc at counter) is insufficient — and shadows are cast by the user's hands. Linear undercabinet placed at the front edge of the upper cabinet eliminates shadow + provides crisp work lighting.

Why this exists

Kitchens are the most lighting-intensive room. The under-cabinet detail is a non-negotiable element of a working kitchen — and a $200-500 line item that's often value-engineered out of builder spec homes.
