Looks like you're off to a good start. 
  
I'd agree with lowering the lights. They'll probably work at that height, but you're probably wasting some power lighting the floor.  
  
I notice you have a glass thermometer in there. Personally I'd remove it, as they tend to break, and can cause lots of issues if it does.
