How different are RRD-6NA vs 6CL vs 10ND vs HxD-6ND? I know the HxD6ND obviously is a HomeWorks product, but I use it for comparison.
As an example, the link below says that the RRD-10ND, RRD-6CL, HxD-6ND LQRJ-WPM-6P should work, but no 6NA is listed. Is this deliberate, and why would a 6NA not work when a 6CL would? Would Lutron simply not have tested this unit or would they have tested it and found it to fail?
I have six of these BR30 that work well with a 6NA I've heard some say that the performance of the 6NA with dimming is just a bit better than for the 6CL, while I've heard others say the 10ND would be better.
6NA aside, when all the items show up in the LED tool, would someone always go for the lowest cost item that's on the list (provided you use the appropriate loading).
I would like to know the fundamentals of what's going on here. Thanks for any thoughts!

Interesting, First off I would expect the Homeworks and the same RR2 part (e.g. 10ND) to treat the load the same.
Second, they probably didn't get a desirable or possibly inconsistent result(s) from the 6NA. If the 10ND preformed as well as stated, the 6NA is the same price. (No need to go further)
To that point, the 6CL also posted near perfect testing. I would recommend the 6CL over the 6NA (by a slight margin)
from my own testing due to increased range on the 6CL(again, slight difference perceptually)
So ultimately I don't have a direct answer with support documentation. But If your load is supported I would use the 6CL. If your load is not listed or close the the min/max of the test report I would go 6NA or 10ND. Personally I like the 6NA because you can change the phase control and this helps with difficult LED's sometimes. The 10ND does not have that option, but fills in where you may need to handle more wattage than the 6CL or low minimum wattage. (Test reports are limited to 12 lamps/fixtures, so in this case the results are the same, but I would venture to guess the 10ND could handle closer to 250watts of LED)
One thing I don't like is the vague footnote on the 6CL (R3). So I called and this is in ref. to the current revision of the dimmer. They told me this is the only version on the 6CL (so why not R1?)
but the foot note is there to differentiate if there becomes an updated version.
Their standard answer for almost all LED applications is use the chart (LED Matrix / Product Selections tool), personally he told me if it's not on any reports the 6NA is best bet.
Some side dialog while he was looking up info, and referring to my questions why the 6NA isn't reflected, confirms my suspicion above that it likely had less than desirable performance compared to the others. He could speak specifically on this combination but said they would not publish a "black list".
I know this from prior interactions with them on these issues, unless there is a favorable report or possible solution, you won't likely find a report card on that item, even though they probably have tested it.
FYI, TCP's in a little hot water legally right now, kind of an interesting story about the board suing the CEO, but we've been selling their LED lamps for few years and the performance has always been great.
