Reviews:
1. Overall efficiency is excellent on both lights – remarkably so, given their continuously-variable interface. I was particularly impressed with the performance of the RRT-15 on 2x18500 cells – outstanding runtime for a continuously-variable light, given the 1500mAh rated capacity of those cells.
