More accurately described as a compartmentalized borderlight, but colloquially called a striplight or X-Rays, is a linear fixture using multiple MR-16, R-30, R-40, PAR56, PAR64, T-3, A-type or HPL lamps. Portable version are available in lengths of two feet to eight feet. Permanent versions can be any length desired: for use as a borderlight, a length of 3/4 of the stage opening is recommended. Typical uses include cyc or drop lighting and general wash lighting. Striplights may retain their color media (typically called rondels if circles of colored glass) within their reflectors (if applicable) via split ring/spring ring design, or through the use of a combo frame.
