ight output, is that a red LED led strip will consume dramatically less power than white. The color isn't a matter of "lens color" but of how the light is being generated. Blue LEDs are somewhere between red Flexible LED Strip Lights and white in terms of power consumption and light output, but I have no idea if they are closer to white than red. I have a light with red blue and white LEDs and generally use RED for everything except for total night walking, and then only when the terrain required better visibility. I would never buy a headlight that only offeres white LEDs Outdoor LED Lighting until they come up with white LEDs that are just as efficient as red.
