Interior-placed lighting recommendations

We've just set up our new cage for our pastel BP Persephone. We bought a modular cage from Constrictors NW, heated with an RHP (Pro-Line) and it looks nice and will, no doubt, function well to maintain temps/humidity/security.

We want to add some light in there (black cage, 36x24x14) because it's not easy to read the temps on the back wall and some light would be nice. She likely doesbn't give a hoot, so it's really for our viewing pleasure. What would you recommend for lighting (keep in mind that heat lamps on top are not an option--must be something to tuck up on the interior front wall/ceiling). Is there something that won't get too hot and won't bother P.?

Thanks in advance.
