The Micro Effects Light (MEL) is an LED light head that mates to a 9-volt battery. 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. The lights include a 9-volt battery clip with a DC barrel connector that mates to the light head. 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 5 pack of lights and 9-Volt battery clips.
