Sure there is :) the brightest of the older Q5/R2 XR-E lights clocked in at over 250 lumens, OTF, constant on, in a calibrated integrating sphere. So a triple setup of those would already be capable of 750 lumens in normal operation. With the better anti-droop, and R5/S2 bins a triple XPG light with sufficient heatsinking should be capable of 1000-1100 lumens without too much fuss.
