When choosing infrared LED lights for a Rear DI setup, you have a few choices: LED Bar Kits or LED Module Kits. The LEDs in both kits are the same LEDs as those in the High Brightness 10mm LED Ribbon. The LED Bars are easier to mount with the included hardware towards the top of your enclosure shooting down to the floor. The Module Kits though are easier to get more even lighting across your surface due to more modules, important to get consistent bright blobs. The more light the better.
