Reefled 90 to Radion XR30 Gen 4 Pro acclimation

[NickHolmes]

I'm replacing a single Reefled 90 with a Radion XR30 Gen 4 Pro in my shallow reef. The Reefled 90 has been running at 100% but I don't know what
intensity to start the Radion at as I don't have access to a PAR meter. Can anyone give some guidance on this? Pic of tank for reference, will be predominantly SPS.
