I had a light gatheringpeep many years ago. It was a green plastic or something cube with black paint on the eye side. Hands down it was awesome if you where going to use a peep. I lent the bow to my nephew. He said he took it to the shop to have it tuned and a new string. It was a perfect bow.I got it back with the same string minus my peep. Never have saw the samething advertised.

If you truely want something to work just as fast in low light as in regular light, you will go with a scope.
