No, at least not in this size that I know of. Mains dimming and smooth dimming to and from zero are just not likely. That said, in larger size, the RLED is available -
http://www.cantousa.com/rled/ - but really meant to replace a 300 or 500
watt quartz. And assuming you don't want to go to replacing dimmers as stated - just lamps - these list around $750. Probably in your case it would cost much less to replace dimmers, but so it goes.
Your in a place where the cheapest way - by way far - to get good dimming is
incandescent. Any
LED solution will have deficiencies short of replacing fixtures and using constant
power and distributed data.
Now - I haven't investigated what it would take to replace with the Arc
System - now liscensed in the US by
ETC - but
call your rep and ask if any of the Arc products could solve your problem. I thoughtthe one
cell with mesh
network might fit but may be a lot of rewiring. Perhaps one of their lamps could work, but I thought they required wiring in drivers and constant powering them (that would be easy)

In general, better to not start a new thread on same issue - DVS may even move these to the old thread.
(And in fact he did while I was posting! How strange.)
PS - the lamps you have are suppose to be dimmable. since I've had the best results with mains dimming using TCP lamps - makes me question your dimmers.
PS2 - you never said how many of the 12
watt LEDs there were. The DMX8DIM would dim 8 circuits at 250 watts max. That would be 20 per
circuit and 8 circuits so 160 of the 12
watt TCP retros. But do try to test one or a few before investing much. It worked for me but but we find LEDs, especially with mains dimming, inconsistent. But all together, the DMX8DIM would be a pretty ;ow cost solution compared to even replacing lamps again.
I wish I could stop in - I could give you some realistic options.
