Then I don't think we disagree about the L2. Cool white for the original XP-L HI is one flux bin higher - 7%, so around 150 kcd. A low-CRI SST-20 would have more throw than that, but the high-CRI is going to be in the same ballpark since the output is lower. This is with the stock driver, of course, which offers good efficiency, no PWM, and the ability to use one or two cells. Giving up some of that for a current boost or a FET driver can increase output and throw substantially. I don't doubt the big numbers for a dedomed SST-40 with a FET driver.
