[RE-wrenches] Wood shop lighting

[Jeff Wongstrom/ Sarah Anderson]

Hello Wrenches,

We have a client with an off grid wood shop and would like your  
recommendations for the most efficient lighting options.  The shop is  
powered by a quad stack, 4.8KW of PV and a 20KW genset.  The main  
part of the shop is 42'x22' with ceiling heights varying from 10-12',  
there are benches along two walls, and machinery work stations at  
several locations.  There is good day lighting and we have stressed  
the importance of light colored surfaces.  We have had both T8 and T5  
florescent lights with electronic ballasts recommended.  From numbers  
that the electrical wholesaler provided, the watts/lumen between T5's  
and T8's appear to be similar.   However, the T5's are more expensive  
and have higher maintenance costs but may require fewer fixtures.    
Is one more appropriate than the other or are there better, more  
efficient, wood shop lighting options?

Jeff
