Talking about RS80 I tried to order more but they are out of stock for now :-(
really like messing with this light.
How about the Convoy L2 getting the White2 treatment? It's a linear driver, and the White2 has low forward voltage, so should be able to get constant brightness with 1 26650 for a while. Maybe some power boosting to get its normal 3 amp draw up to 6-8amps?
