I am going to recommend replacing the old 400 w. M-V fixtures in a lumber storage warehouse with either 250 watt Metal-Halide or 250 watt High Pressure Sodium.
According to the owner, color rendition is not TOO important, but maintenance costs are. I'm considering the HPS due to the lamp life being 24,000 hrs. versus 10,000 hrs. for the M-H. I'm just not too sure how bad the poor color rendition will look.
I have used M-V and M-H in the past.
Has anyone used HPS for warehouse lighting and been satisfied with the results?
