Ian can get infra red spot light kits but we don't know how bright they are and they don't come with a case. It's just the ir led's on a circuit board. I can't remember the price but I thought it was like $20 or something. Anyway you can talk to Ian about that if you'd like. We were going to order some and test them out but due to some financial problems we will not be able to that at this point in time.
Here's a cool website for some ir illumination but they are expensive. I thought you would like to look at it anyway. I found it interesting.
