Being an electrician, I went to a lighting school several years ago and HP sodiums was once the trend. But most don't like the orange cast. Mostly places like Wal-Mart and other stores are going for the metal halides which are bright white. It makes their customers also feel safer with the brighter light. Put two stores together one with sodiums and one with metal halides more customers stop with the halide lighting. With all of that said I always adjust the orange cast out. Even though it is not true to life. If memory serves me the sodiums have a much longer life span. So the electrical companies prefer them.
