I'm selling a pair of Mitras LX 6200 due to my recent upgrade to LX7. I bought them 4 years ago new and used them 6 hrs a day in efficiency modes. The power supplies were replace 5 months ago. The life of these LED clusters is about 50% so they have decent life left. Having said that, I'm selling them for real the price of a refugium light as it would be a crime to throw them out. What you see is what you get. Asking $100 each and pick up in Elk Grove.
