Designed for machine vision applications that require broad illumination over a wide area with controlled fall off. This BALA (Broad Area Linear Array) bar light series is expandable in 1″ increments up to 82″. Applications requiring an even wider area of illumination can utilize two BALA bar lights aligned in parallel, facing each other. AL150 derivatives include AL4424 (4″), AL4554 (9″) and AL46120 (20″) (which represent legacy part numbers)
