Stelthy I am sorry to argue with you but I think you are sending the wrong message by saying that if it is not 2700k or 6400k you will be all set. That is far from the truth. Those are not the only spectrums plants use. Any spectrum in between will cause problems but not from an 1/8 watt indicator light.
Ok it was a bit of a mixed message, what I meant was : in the wild cannabis still grows from seed to bud through sun (DAY) and moon (NIGHT), (its never 100% dark), Because of the moon.
Also If you note that the spectrums found in most growrooms (except LED etc) are mainly either (6400k-BLUE-MH etc) or (2700k-RED-HPS/SON-T) and The possible Green (night lights) from time to time, The red and blue spec grow lights can and will damage the plants night cycle if left on, the green will NOT harm the plant at all! I agree completly that the 1/8th watt red indicator light wont harm the night cycle, BUT as an added piece of mind to either block it out or change it to green would be even better than having any other type of light showing - STELTHY
