Can I use different Radions?

[Steve1500]

I am upgrading to a 180DT (72”L x 25”Wx 24”H) and will use Radions and T5s on a hybrid fixture. I want to use 2 Radion XR30 G4 pros with either the XR15 pro or XR30 G4 (non pro) in the middle of the two 30 pros. They have different output wattage and I am concerned about different light coverage and Par. The lights will be about 15” apart. Will the two 30 pros on the ends make up for the lesser wattage light in the middle? Will there be a noticeable difference? Lights will be about 12” above the water.

I'd go with the regular XR30 G4 in the middle. If you use an XR15 the center zone will be noticeably dimmer unless you hobble the two end lights by turning down their intensity.
