[Nelpag] photo/essay on Musco sportslighting

["Karolyn Beebe" <keedo@merr...>]

 Tim Grunewald of the Wehr Astronomical Society brought us a
 dandy photo-essay on a Musco installation, starting on this page:

They told the Recreation Department that they were installing full cutoff lighting.
  
My concerns go far beyond astronomy. It is glare elimination or reduction, and light trespass that I believe are most important, especially for seniors. It is as dangerous to a driver as having a cellphone glued to the ear while driving in hazardous conditions. ( this is one of my definitions of stupid ) Of course, my stargazing will also benefit.

We certainly need SofT Lighting Systems to get an advertising campaign going in the Northeast. Before long, there will be competing systems. I would think it would be a lot easier for players to see a fly ball at night. Some of Musco's luminaires at Marvin Field are directed at an angle of 45 degrees toward the private homes. Regardless of intensity, it would be necessary to put up a wall or a dense line of staggered trees to minimize the trespass. 

in reply to Cliff Haas who wrote in part:
For Musco lighting to control light trespass and uplighting as well as improving the visibility for players on the field relatively well it needs to be mounted very high and aimed downward rather than outward.  The TLC system must also be employed.  Their Level 8 shielding is ineffective and since it is highly specular it does not work to either mitigate glare, skyglow, nor light trespass problems well at all, especially when the luminaires are mounted lower than 50 feet high.

For the past several years I have been encouraging Del Armstrong to establish a distributor here in New England because his SofT Lighting Systems is the only large field sports lighting that meets true full cutoff optics classification.  We have been seeking a firm in Mass that specializes in sports lighting without much luck.  If you know of any please let me know off-list.  It is superb lighting and uses a mix of HPS and pulse start Metal Halide with 1000 watt lamps to reduce maintenance while also providing excellent color rendition without needing to put 250 horizontal footcandles and 175 vertical footcandles on the field.

Clear skies and good seeing,
Keep looking up!
