Holds 4 lights, but I've just tested it and it seems the 2 outer ones work, the 2 center ones probably don't. And yes, I've reduced the price to reflect that.
Visually, it is in Very Good Condition -- looks unused.
Model I. 110 volts.
Plugs into wall outlet. For use with 375 watt max. reflector type photo lamps. Or can work with standard household bulbs as well. Folds in half when not in use.
