Here are a couple pictures of my 2 big girls. I installed puck lights above each of my enclosure. The lights can be dimmed or brighten ed has 4 color selections and comes with a remote.
Arachnids cannot see red spectrum so they are unaffected by the red lights ( others they don’t like and will run and hide)
The downside to red lighting is some detail is lost plus i don’t have a great camera so its hard to get a picture without a flash which is not good for them. I do enjoying sitting by their enclosures at night and i turn out my lamp and just turn on the puck lights i can watch them go about the tank without them being bothered.
