v4 Compliant Stadium/Athletic Field Lighting

There is no such thing as a compliant light.  Fixtures can be installed in a way that makes them non-compliant.  Having too many fixtures can make them non-compliant.  The design for the site as a whole needs to be compliant, not any individual product.  I find athletic field lighting very difficult with this credit.  I'm used to HID lighting.  I see that Musco has LED lighting now and has installed this LED light in at least one athletic field that is LEED Gold.  The article doesn't mention if this credit was earned.  I can't find the project scorecard online. The problem is that most athletic field lighting needs some uplight so the ball doesn't disappear when high in the air.  LZ3 limit on uplight is only 3%.  I haven't seen a project with uplight this low. The other option is BUG rating.  Musco and other have pointed out in the past that their fixtures are adjustable.  BUG ratings are not suitable for adjustable light fixtures.  Each head is aimed at a different point in the field, each head has a different angle and different lumen values in each range.  The BUG rating would need to be calculated on each fixture.  They won't do that.
