InWalo offers practical illumination from a linear in-wall luminaire. The InWalo housing requires just 5/8" of mounting depth - the thickness of common drywall - so the luminaire mounts on top of the wall studs. The driver compartment slides behind the luminaire for totally flexible installation between the wall studs. A removable LED and optical cartridge permits access to the driver without disturbing the drywall/housing connection. InWalo can be installed as a discrete or continuous linear luminaire and oriented for either uplight or downlight.
