Re: LED taillight bulbs
Absolutely. But given the circumstances, luminous output is an at least relatively valid way of measuring the difference between light sources mounted in the exact same location relative to all reflectors in the tail lights.
I believe the reason a 210 lumen LED array can perceptively outperform a 400 lumen incandescent bulb in our case is due to the nature of an LED light source. By this I mean the fact that even though there are 400 lumen coming out of the incandescent bulb, a portion of this is filtered out (blocked) when it passes through the tail light lens (the yellows and blues that make the light appear white), whereas the LEDs are emitting pure red, and under perfect circumstances, the lens should, in theory, not block any of the light emitted from the LEDs. In other words, if our incandescent bulb emitted pure red, as the LED does, it may measure an equal, or lesser luminous output, which in our case, would cause the LED to appear brighter.
