The Micro Effects Light (MEL) is an LED light head that operates on 9-12 volts DC. Its narrow beam light is ideal for small prop and costume lighting projects. These small LED lights can also be used as stage markers, equipment markers in dark areas, and for other theatrical and stage needs. There are seven available colors: warm white, red, green, blue, amber, orange, and purple-magenta. Plus, a blacklight version is functional with fluorescent tapes and paints. This is a 2 pack of lights. See our Power and Interconnects items to go along with the MEL lights.
