The statement was made that red lights for night vision were a "myth."
I've spent enough nights in the field with only red and green-filtered light. When I had night vision they preserved *some* vision should the lights go out. So I'd say it's not a "myth." Anyone that's certain it is a myth should go tell the SF bubbas.
Good night vision requires at least 45 minutes in darkness. No moon, overcast, rainy nights were going to stay dark no matter how long you adapted. But Human night vision can collect more of whatever light is available once adapted.
But it usually took me a couple of days to make that work. We moderns have too much bright light for too many hours. It's a shame, really, because it's a fantastic experience to glide along under starlight as if it's daytime.

Check in my photo album under "Modifications - Cabin Lights." I used little LED strips on top of the aluminum window frame and used stick-on conduit to make the wires disappear. The original wimpy Perko lights were removed.
A couple things to be aware of. LED lights can use really thin wire. I used phone wire (22-24 gauge??). But you need to make sure that all connections are perfect and limit the number of strips wired in serial. LED lights sold on Ebay as automotive 12V sometimes have a 13-15V range, because when your car is running, that's the available voltage. Installed on a boat sitting at anchor, it is possible for your battery to drop below the LED strip's optimum current, or voltage drop over a longish wire. A couple individual LEDs might dim or wink out. Kind of annoying. |
