My goal is medium light, which from what I understand would be 40-50 PAR. However, I recently changed my lighting on my 90 gallon from 2x Planted+ to 2x XR15FW G4 and need help translating the 9 hrs of 40-50 PAR I had before to a longer light schedule that ramps up to peak intensity at midday and back down again. I'm assuming the peak intensity will be closer to high light but I'm wary of overdoing it.

Does anyone have any suggestions or experience they could share programming their own light schedule? How much of the day should be spent above the target PAR, vs below?

Thank you for your help!
