Mixing new kessil with old kessil

[vetteguy53081]

I have 360's mixed with AP700s. The 360's offer more shimmer whereas the AP700s offer deeper blues

I have the same issue. I initially purchased two brand new A360WE's over one of my 75G tanks and after 6 months of use a fellow reefer was selling a used one for cheap. After hooking all three together in series using a Kessil controller I noticed the light from the older light was noticeably different. It was not as bright and the spectrum was way more into the blue range, I love the lights but think they degrade fast.
