I have two AI Prime HDs bought within two months of each other controlled as one parent and one child in myAI. My thought with only having one schedule would be that the lights would match in the color they are outputting but one of my units is always a little more green. This is most evident during ramp up/down when there's very little to no white as this washes out the color difference. I don't think buying them at the same time would have changed this since I don't expect the output from a single unit to change with an additional two months of use. Has anyone had this issue before? I've wiped down the lenses of both to see if there was maybe something on one of them but that didn't change anything. Do you think resetting each individual light and then pairing them together would help? Below are pictures showing the difference, try to figure out which one is more purple and which is more green. It's really hard to capture in a picture but when the light gets down to the sand it is very evident (even in the water column it is very evident).
