I have two sets of the GHL Mitras LX 6200 HV Pendant for sale. These are about 1.5 years old and comes with all the accessories, and of course, the "ghl" sunglasses".
These are black colour unit and in excellent/mint condition. I purchased them for a new reef build, but decided to hold off on the project for now.
