B and P person emailed me that Nora bulbs are compatible with their dimmers. But I went on Nora site and couldnt find the bulbs he recommended.
NIO-4 RTLA or NIO 4 RTLANDC or NIO STLANDC "No results found" when I search on Nora Lighting site or other sites. I emailed back, waiting on response. Have you bought Nora bulbs before ?

Yes, I buy Nora. Those part #’s are not for lamps; they’re architectural 4” round trimless LED’s. We use 6” Nora LED’s on some commercial projects.

B&P are clueless.

Also unless the LED lamps you’re using are less than 5w each, you’re likely overloading the dimmer.

The first batch of bulbs (Satco) were 5 w LEDs, the second batch were Home Depot ecosmart brand 2.5 w LED. Both flickered and strobed.
Where can I buy Nora candelabra LEDs ?

I may be misinformed here, but isn't Nora a fixture manufacturer and not a lamp manufacture? As I mentioned in my previous post try Philips candelabra lamps with a reverse phase dimmer. While I have never done 25 or so on a single dimmer, I have done 12 or so without issue.
 
From my previous experience with LED candelabras, I spent two days using the "scientific method" change everything out until it works. I gave-up and put incandescent in. It's my belief that candelabra LEDs are too small to have good filtering. It's the square wave thing problem.

You may have a point. I have found that candelabras behave differently even within the same manufacture family.
 
Well, I put in 28 LED candelabra bulbs and they flicker even on just a Lutron 3 way switch. (no dimmer) I then replaced the bulbs with 15w incandescent bulbs and no flickering. Are you having trouble with LED candelabras ?
 

LED'S VERSES INCANDESCENTS - Are they really more energy efficient ?

As shown in the two images, LED light and incandescent light do not have the same characteristics and LED light, by virtue of the excessive amount of toxic blue wavelength light, is a low-quality light. It should be noted that the reason that the manufacturers use blue wavelength light in LEDs...

It is my belief that the candelabra base LED's are too small to have a robust circuitry to provide enough filtering to prevent flickering.
 
All LED replacement lamps are garbage compared to a good quality LED luminaire as the manufacturers are stuck with a form factor that is not optimal for the LED source output and heat management so compromises must be made. Candelabra base LEDs are some of the worst because they are so small.
 
When there's only one LED candelabra bulb in the fixture does it still flicker? If not, then maybe with multiple bulbs they are coupling their interference to each other and causing complex oscillations in their circuitry, resulting in flicker. In other words, what is called chaotic behavior.
Lack of sufficient filtering capacitance (as mtnelect has mentioned) could aggravate such a situation.
