About this file
This is a photometric analysis document prepared by the City of Leesburg, Florida, for the 5th Street Parking Lot Expansion Project (IFB No. 26-012-HG). The document presents detailed illumination data for the parking lot design, specifying lighting fixture requirements across three parking areas: Central Parking, East Parking, and West Parking. The project utilizes GranVille Gen3 P30 Performance Package lighting fixtures operating at 4000K color temperature with Type 3 light distribution. The lighting plan calls for 17 fixtures in one configuration and 6 fixtures in another configuration, each rated at 61 watts and 122 watts respectively, with 0.95 light loss factor. The non-mandatory pre-bid conference and site visit occurred on February 25, 2026, at 10:00 A.M.; questions were due by 5:00 P.M. on March 2, 2026, with addenda issued by 4:30 P.M. on March 6, 2026; bids were due by 11:00 A.M. on March 18, 2026; and intent to award was scheduled for March 27, 2026, with final award at the City Commission's next scheduled meeting.
The photometric analysis reveals average illumination levels of 1.8 foot-candles in Central Parking, 1.8 foot-candles in East Parking, and 1.5 foot-candles in West Parking, with maximum readings of 4.1, 3.9, and 4.4 foot-candles respectively, and minimum readings of 0.6, 0.4, and 0.3 foot-candles respectively. The uniformity ratios demonstrate variations across the parking areas, with Central Parking achieving a 3.0:1 average-to-minimum ratio, East Parking a 4.5:1 ratio, and West Parking a 5.0:1 ratio. The design was prepared by Steve Prior on January 12, 2026, and represents the engineered lighting specifications that qualified contractors must implement in accordance with the project plans and specifications.
