Nancy: I assume that you will receive useful information from others, 
but my advice is to avoid internal lighting, as apart from uv issues, 
you can expect an increase in internal temperature from some types of 
lighting that may affect sensitive items. Also, lighting externally is a 
more secure method when it is necessary to replace globes or tubes, as 
the task would not requiire the presence of a curator and/or a security 
officer. For very sensitive items, I favour a timed switching device 
actuated by movement or pressing a button.
