Can I use a lower wattage Lamp with my current Metal Halide Ballast?

Yes. If the ANSI code or Ballast Reference number is the same, you may substitue one metal halide lamp for another one that is a different wattage.

For example, with Philips Lighting there is a 400 watt ED37 Mogul Based light bulb with an ANSI code of M59/S. The 360 watt ED37 Mogul Based light bulb has the same ANSI code therefore this item could be swapped out for the other without any problems occuring. There aren't very many of these but it does exist.
