ADDENDUM NO. 1
“BIDS FOR LUMINAIRES”
There is a correction to the first section of the specifications. Depreciation standards
were incorrectly listed as L95 and should be L90.
1. Full Cutoff Luminaire Standard 90-200-watt (Qty. 30) LED Shoebox/Cobrahead Luminaires
This fixture shall be sized to meet the Pedestrian Areas lighting standard of 0.8 fc roadway average after L95 L90 depreciation
standards. This is based on approximate roadway widths of 40-105 feet, 40’ pole mount with 3’ sweep, and poles spaced every 180240 feet per block face on a staggered pattern. There is a 3 foot setback behind the curb. This is anticipated to need wattage in the
range of 90-200 watts.
This addendum should be acknowledged on your bid form.
