.21 V in general would not make that big a difference in the brightness of the LED fixture. If it's a fixture with an active regulator, it should make no difference at all; but even with a cheaper design using e.g. a dropping resistor it should be at most barely noticeable.
You'll have a much larger voltage difference when using battery power alone, at least once the surface charge has dissipated.
It sounds to me more like a fault in the lamp itself.
