Picked up a set of wireless LED lights for my shelves today. Just set them up and they make the display looks 10x better! Each set comes with 4 light pods with 5 ultra-bright LEDs on them. Each pod is powered by 3 AAA's which are included as well. With the lower power consumption of LED's and the fact that these won't be on 24/7, I think the batteries will last quite a long time. I am going to go back and pick up several more sets to light my displays on top of the cases and my Transformers shelf!
Ya I still have some space to fill out haha
