I heard that the Cooper OV-25s are now called the OVW (at least the full-cut-off ones are). They have the same reflector as the OVF/OVY/OVD though, not the westie style reflector. A member here has a 400W HPS Cooper "OVW".
Was their a reason for Westinghouse chosing the numbers they did for their model numbers or was it done at random? GE went by the maximum wattage for their numbers in their model numbers but others seem to jsut have done it randomly.
