I have tested a RRD-6CL and RRD-6ND dimmer with a number of LED bulbs in combinations from 1 to 6 bulbs, all BR30 65W or 75W spanning from 2700K to 4000K.
The best bulbs with the 6ND are a Philips 2700K warm glow 65W claiming to be a great dimmable LED (it is, but looks even warmer than 2700K to me) and a Maxxima 65W (edit-it's 75W)
Both of those work well with the 6CL, in addition to a great eagle 65W (edit-it's 75W). The great eagle with the 6ND was not nearly as good, flicker at lower light levels I think, but is almost perfect with the 6CL at all but the very lowest light output (hint of flicker there). The Philips and Maxxima may have been slightly better at dimming to low levels with the 6ND but are still definitely usable with the 6CL.
Others inuding TCP, Maxlite, Amazon basics, hyperikon etc all had problems with flicker, buzz, poor dimming behavior or some combination.
Is there any compelling reason to use the 6ND over the 6CL? Seems like it should be better with LED's but doesn't really seem to be. This is new construction so have the neutral available everywhere.
Any suggestions on a good higher wattage BR30 bulb? Don't think any of the 75W I tried were really that good. With 12 foot ceilings the extra output would be nice. (Edit, never mind, I lost track in my notes which were 65W and which 75W, turns out two of the better bulbs are 75W).
Anyone have any experience yet with the new pro-led dimmer?
