LED strip earns no credit alone, but it can help with WELL color, flicker, glare and circadian points and LEED v5 quality lighting. What each line asks by run.

Facade lighting under a dark-sky ordinance: lighting zones, MLO lumens and Title 24 watts per square foot turned into feet of wall washer, uplight, curfew, CCT.

Elevator cab LED lighting answers to the elevator code: 5 fc at the threshold, a 4-hour auxiliary light on the car, NEC 620.22 and California's 0.6 W per sq ft.

LED strip emergency lighting needs a UL 924 device in its power path: a load control relay, a battery emergency driver or a listed inverter. Which, and when.

Aluminum LED channel grounding and bonding: why a Class 2 strip channel has no ground to join, when 120V strip changes the answer, what to tell the inspector.

Acoustic baffle LED lighting integration: a channel in air on the baffle edge, what the felt's ASTM E84 Class A covers, plenum wiring, access, strip, driver.
