Lumatek Galaxy electronic Ballasts

I have 2 Lumatek 600w & 1 Galaxy 600w electronic ballasts for sale. They have been gently used for one cycle and work great.
You can purchase one for $120 for all three for $300. I have actual photos of my ballasts included in this post as well as pictures from online stores selling them. On average they sell for $120-$200. If you have any questions feel free to contact me. Please serious inquiries only.
Thanks!
