The Recording Strip Light from PunchLight is a compact light unit designed to fit in tight spots. It has a strong magnetic base which allows it to attach to steel surfaces. The unit must be connected to the PunchLight DLi, PunchLight GPI, or PunchLight MIDI (all sold separately). The recording strip glows bright red to indicate recording punch in/out. The recording strip can be used above the door, at the entrance to recording studios, to warn others that recording is in progress.
