building monitor tank, need lighting ideas

[reptile king]

I'm building my asain water monitors cage, and i need some ideas on the best way to set up the lighting inside so i know it get the right temp, the hole enclosure will be made of plywood, and then sealed and tiled in the inside for easy cleaning, and then it will have a 5 foot sliding door on the front, the size is going to be 3' deep 3' tall and 8' long, and all plywood, except for the sliding glass door on the front, any tips or ideas would be great
