2 lumatek dual output 600 watt ballasts

2 barely used Lumatek dual 600 watt ballasts. These were only used for one cycle and are great ballasts. Each ballast can power 2 600 watt lights. They can also run 1 out of the 2 lights at one time. Also each hood (light) can be turned from 150,300,600 and super lumens.
