I don't know the numbers; I suspect the info has been lost to time as the various Arc forums have disappeared.
I suspect the numbers were relatively low, as the Premium tint LEDs were rarer back then and the Fraen optics were a couple of special runs, IIRC. I feel it's moot, since you can turn any Arc LS into the same unit by changing the optic to the Fraen and an SSC P4 LED will double the lumens with good tints. I tried the Fraen and didn't like it, and moved to reflectors. I still have a couple of Arc-LSes around the house on duty.
