I have 2 L2D's and 2 L1D's, the only issue I have had has been the batteries, I have used one of the L2D's for a year now, the others, less time.
With L2D, all it takes is one battery to be bad, like high series resistance, and the light will do what you say. The light goes to low output when the series battery voltage goes lower than "X" volts, that is by design.
I only use NiMH AA's and have a good battery charger that can evaluate each battery for health. I have found some batteries are not good, many batteries will be greatly improved by doing a refresh cycle. Do not assume the light is bad before you are sure about the batteries.
