The HPL series light fixtures are made from a clear cast acrylic piece that is laser engraved with the text. This engraved piece is suspended from an aluminum "box" that contains the high power LEDs of the required color (red LEDs standard). This light fixture is then mounted parallel to the wall via a steel plate attached to the wall and a magnet on the rear of the light fixture. Power to the fixture is 12 VDC.
Please Note: "CMF" indicates "Ceiling Mount Flush". The "CMF" option mounts the steel plate to the ceiling and the sign magnet is located on the top of the fixture.
