A shelf light (300) is provided as an LED linear light assembly (300) having a flexible LED linear light component (302), with a series of LEDs mounted on printed circuit boards (PCB's) (308). The light component (302) has a double channel (304) with an extended aluminum track. An LED PCB jacket (306) encloses the light component (302) and is of uniform thickness. Reflectance members (310) comprise a pair of members (312, 314), each having an elongated configuration and mounted on opposing sides of the light assembly (300). Movement of the reflectance members (312, 314) permits variation of apertures of reflectance, thus varying the light intensity and direction.
