Kessil LED Recommendations - Does anyone have experience?

[jesstabby]

We are looking to upgrade our DSuny LEDs. We have an APEX gold controller on order so we want Apex compatible lighting + our current LED are good, but we want to maximize our coral growth. We are set on LED lights (due to low heat and power consumption), but would like recommendations from anyone on success they have had with Kessil or other LED recommendations.

Thanks
