Red

Green

Nitecore 25mm filters on a Streamlight 2L-X (w/usb rechargable battery) on low, which is 40 lumens. White light was from a desk lamp.

If anyone knows how to make multiple photos show on a post let me know haha

      A big part of it has to do with running night vision. On aircraft what used to be red lighting is now NVIS friendly green. My limited understanding is that it is within a range of the light spectrum that can be seen by the naked eye (obviously) but prevents glare/bloom when seen through night vision.
