Thought I'd post a quick update. The locker itself is working great but, thanks to the marvel of flash photography, the pics don't show really how dark it is in there. I tried one of those battery operated closet lights stuck on the door, but it was about useless. So I ordered a 16' led battery powered strip light to try. It runs on 3 AA batteries, is sticky backed, and forms nicely around the door opening. And man do they light it up!
For 15 bucks they were well worth it.
