Ok, so yesterday I put in an order at AH Suppy for a pair of 36w retrofit kits. Can I expect any real difference between 5000k and 6000k lighting in a low-tech set up? The company was currently out of 6000k bulbs, but by their own documentation, there is little difference other than the color spectrum. Yet, I keep seeing references to 6000k being the bare minimum that I would want. Anyone have any experience with this? Can I get by on 5000k for a short while?
