I've pretty much settled on 6
low bay 400 watt metal halide.

In our warehouse we had metal halide and the power company paid us to
take them out and replace them with 4 tube high efficiency fluorescent.
The ones we had were 1000 watt and we are getting better light with less
than 200 watts.

The old lights had bulbs that cost $100 too. Now, all four would cost
about $16.
