So as I start to unbox all my equipment with expected delivery of my tank I as able to find some used equipment from my previous built. The most expensive used equipment was an EcoTech XR30 gen 5. I wanted to use with new gen 6s. I never looked at the light side till now but I see rust on the metal screws and cracks where the screws were over torqued or swelled up. Very bad wicket for a light I only used for 6-7 months previously.
