Ballast from Lumatek Zeus pro 2.9 version, but I think it will be compatible with 2.7 model aswell.

Great for parts or a straight replacement for old existing one! All tested and are working, comes exactly as seen in the photos and we have 8 In total all in similar condition, so you may receive a different one to the photo but as said all in the same condition and model.

Any questions just ask :)
