Artificial Lighting Question
 

Hi folks, We are renovating our sunroom room which is 2m x 5m (6' x
16') with full afternoon sun on the long side. Australian climate, similar
to Florida. My question is, would it be beneficial to include (say) 2 x
1.2m (4') fluoro fixtures in the ceiling with Grolux-type tubes, or would it
be pointless? Thanks for any replies.
