I'm using 28 XML for main lighting and 24 xpg for supplementation. The XML max out at 1500 mA and the xpg at 1A.

The XML are cool white with 40 degree optics. 12 royal blue xpg and 12 neutral white xpg with 60 degree optics. This way I can adjust the colour temp from very yellow to very blue. The pendants will be as close to the ceiling as possible.
