Thanks for the input!
@Bill. As always, your two cents is worth a million bucks! I was actually thinking of mounting them on the tank itself, not the lid. But I hadn't considered having the ability to move the lights.
@Paul. Thank you sir. I have an empty 10gal. I can experiment with first.
I've been keeping my eye on these type of lights for a couple years now for accent lighting for my pond, and more recently a "permanent" Christmas light option. Some kits are RGB+W and come with a remote that you can pretty much do anything with. I just didn't think about vivarium use until yesterday. The set I'm looking at is similar to the link, but comes complete with power for $18.
I'm a designer/craftsman by trade and can't help myself but go outside the box with things. Since I'm dealing with the health of live plants and animals, I thought I would check with the experts first. Keeping my 'phibs happy and healthy is priority one.
Thanks again for the help, I'm sure I'll be asking for more soon!
