I wouldn't be. 200 lumens OTF from 3 LEDs would mean ~85 lumens from each LED. Even with XR-E P4s, that's only 350-380mA to each LED. Well within the limits of reality. 360 lumens OTF would require ~150 lumens from each LED. For XR-E P4s, that would be ~750mA to each LED. That's on the high side of current for what would be considered an acceptable runtime using 2D alkaline cells.
