The Arida DWW is the specifiers answer to close-in facade lighting. Able to perform uniformities better than 4:1, while spacing fixtures up to 20 apart with a 5" setback, the DWW performs like no others. Average levels of light including the above parameters are 3+ FC and 2 FC, 40 above the fixture. Lighting glass exteriors was never easier, from the ground or from the top of the building.
