originally $6,000+ the lightbrush 300 system consists of a light source with timer and dimmer and a fibre optic wand with various acrylic light shapers.  Used for painting in light with studio product photography.  These have a reputation for the fibre optics getting yellow and dimmer over the years however this unit comes with an additional new liquid filled wand cord that is clear and one stop brighter that the original equipment.
