The 3 watt USB display light is powered by any 5 volt USB port. So weather you are using a power bank or a laptop it is super easy to power this light. It is powerful enough to make Yooperlites and other longwave minerals fluoresce very nicely especially in a dark room. It works best within 5 feet of the light but can reach even further in a dark room.
This is perfect for small displays or making your own display. Use multiple lights to light up bigger areas.
This light is small and light and comes with a rubber grommet for mounting the light.
