This is what I'd install. http://interstate-builders.com/lighting Seed company that I work for part time replaced 400 watt metal halides in their warehouses with T5HO (54 watts each bulb) six lamp high bay lights. They use less watts and put out alot more light than the old metal halides. Night and day difference between these two lights. Seeing is believing!
