Office lights and hall lights: lux, UGR, not one 40 W LED
Offices need UGR and a dimmable driver. Halls need high lux, IP, a highbay. One “40 W LED” does not cover both files.
Schedules often lump “40 W LED” for the open office and the hall. Offices: UGR, colour temperature, a 0–10 V or DALI driver if the file dims. Halls: lux on the machine bed, dust IP, a highbay — rarely the same UGR as a desk. A highbay at a 2.8 m plaster ceiling glares; an office panel at 10 m is dark.
Send mounting height, the lux target, and whether you dim. Escape lights are their own lines — not inside the task-lighting lump. DALI or 0–10 V · Emergency lighting
