The coast Guard cannot pass a light bulb unless they test it in the fixture it matches. They test for brightness and visibility to the specified distance. Colored (red/green) nav lights are not white leds in a colored housing. They are colored leds in a clear housing. They also have to be overbright when new as leds lose brightness over time. In the case of the Lopolight, a high quality nav light they are certified to be the required brightness at the end of the 5 year warranty period, running 24/7. If your boat was in an accident at night, even if you were not at fault, and there was a court case over it, if your lights were not Coast Guard approved you could be held at least partially liable. Brightness of the lights isn't the only thing that counts.
