Lumen Industries CP-32 Mushroom Units

I picked up these RARE units as I have never seen anything from this company. These were built by Lumen Industries here in the US. I have never heard of this company and I have never seen anything else produced from them. If anyone know any additional info, please contact me. These units are similar to many of the other "mushroom" style units that were popular in the 90's but have larger lenses and have a unique design how they are positioned on the dome. The unit has 2 X 24 volt, 250 watt lamp that rotate to the beat of the music. This unit puts out a ton of light!! Unit made here in the US.
