All cool with the compatibility chart on bulbs and dimmers, but I would like to dig a little deeper to understand how it works.1. Why Lutron doesn't publish Minimum and maximum wattage on dimmers? 2. What exactly are the technical requirements for a bulb and dimmer to work properly? I used a MACL-LFQH-WH to dim 3 4.5W LED's and all of the lights pretty much staid on and didn't really dim enough.Then I used a MACL-153M to diem another set of same 3 units of 4.5W and it did a better job on getting them dim, but one light bulb still had a bit a glow while the other 2 were dim all the way. Other than using the quick compatibility reference, could anybody tell me the reasons, technical requirements on why some dimmers work better with some light bulbs and other do not? Thank you...
