Technical Specifications
Supply of LED Luminaires for Street Lighting
PURPOSE
The purpose of this technical specification is to provide information that will allow prospective suppliers to prepare submissions to supply LED luminaires for street lighting throughout
the City of Denton (COD). This specification defines the minimum physical and electrical characteristics required by Denton Municipal Electric (DME) for LED luminaires. DME will be
using the LED luminaries as a direct replacement of approximately 8,000 existing High Pressure Sodium (HPS) fixtures over a multi-year period. DME currently uses 100W, 250W, and 400W
HPS cobra head-style roadway luminaries. Upon deployment, the LED luminaires will be integrated into a centralized lighting management system.
Denton Municipal Electric (DME) has reviewed, through an LED pilot program, and determined the following to be suitable manufactures of LED luminaires for current and future lighting
projects: Phillips (Signify), Holophane Lighting, and Howard (Power Solutions); therefore, the aforementioned manufacturers will be accepted.
The intent of this procurement document is to select a single supplier that delivers the best value for the comprehensive Project scope and to execute the Contract with the successful
Proposer. As further detailed in this RFP, only Proposals that are responsive to all elements of the Project scope will be considered for evaluation. The Successful Proposer that has
executed the Contract with the City (“Contractor”) will be responsible for the completion of the comprehensive Project scope.
SERVICE CONDITIONS
Site Location: The service location is within the Denton, Texas area.
Service Elevation: Approximately 640 feet above sea level.

QUALITY CONTROL
The manufacturer shall be responsible for the quality control of the manufacturing processes to assure that all requirements of this specification are met. However, the City reserves
the right to observe, inspect, and may require additional quality control investigations, either by its personnel or an independently employed quality control investigator, at any stage
of fabrication, at the firm’s facilities. Failure to adequately maintain quality of fabrication until completion shall be grounds for cancellation of the order or any part thereof.
Proposed products must be available, in full production, at the time of this bid. Bids for prototypes and conceptual products will not be accepted.
WRITTEN WARRANTY and GUARANTEES
Written guarantees shall include any limitations as to the nature of failure or time limitations. The guarantee shall begin upon receipt of the accepted units, not on the date of manufacture.
Guarantees shall indicate whether or not it is made on a full replacement basis or a prorated basis. If guarantee is on a prorated basis then terms shall be concisely defined. Manufacturer/suppli
er shall guarantee the goods furnished are of high quality and agrees to replace any goods found to be defective during inspection, installation, or service for a minimum period of 120
months (10 years). All warranty information shall be submitted prior to award of contract and cover all parts including the driver. Warranty period shall begin after units are delivered
to COD Warehouse
The luminaire manufacturer shall warranty the performance and construction of luminaires to meet the requirements of this specification, and must warranty all parts, components and appurtenances
against defects due to design, workmanship or material developing within a period of ten (10) years from the date of acceptance by the COD Warehouse.
The inability of a luminaire to be dimmed will constitute a luminaire failure.
Failure of 10% or more of the LED light sources (packages or arrays/modules) in a luminaire will constitute a luminaire failure.
The warranty must apply for application on all of the DME’s existing electrical systems, both grounded and ungrounded.
During the warranty period DME may, from time to time, test a random sampling of 10-20 luminaires for verification of light output per IES LM-79 and to test dimming functionality for
a given luminaire population. The percentage of luminaires not performing as required in the random sampling will be applied to the total population quantity to determine the number
of new luminaire replacements that must be delivered to DME by the manufacturer, without expense to DME.
Failure(s) shall be the responsibility of the manufacturer. Respondent shall provide a methodology for return and replacement of any failed unit at no cost to DME. The respondent shall
guarantee that COD will be represented by the Manufacturer, should an issue arise, and that all manufacturer’s warranties will be in effect for the life of the contract.
