Hello LlByTheSea,
Thank you for providing that information to us! As Julia had mentioned, we have flagged that LED bulb with our testing team as the bulb that we tested had a lumen output of 665 and was drawing 7watts.
Unfortunately, since we have not done any testing with this LED bulb you have, we would advise reaching out to the manufacturer for a recommendation on a dimming control that will work best with it.

Alternatively, I was able to locate another compatible HALO LED downlight for the MACL-153M that is comparable to the RL4069S1EWHR. The model number is RLD4069301EWHRand is being sold at home depot, please find a direct link @ https://www.homedepot.com/p/Halo-RL-...%3A%7B0%3A1%7D

Thank you!
