2 1.0 SCOPE 1.1 The purpose of this specification is to insure the furnishing of a high intensity discharge lamp of high quality, manufactured in accordance with current applicable Electrical Industry Codes, American National Standards Institute and Underwriters Laboratory requirements. 1.2 It is intended that this specification shall serve as a guide to the supplier to prepare a quote. This specification is not intended to be a detailed a specification. The supplier will furnish complete descriptive information including the specifications for the lamp being quoted. 2.0 GENERAL REQUIREMENTS 2.1 The lamp shall be designed and constructed to the most current recommended practices of the IES, ANSI, and NEMA. The lamp operating voltage and ANSI ballast codes shall be as follows: Lamp Watts/Approx. Init. Lumens Lamp Type 100/9,500 Metal Halide (MH)/Pulse Start- ED 17/Med 175/13,500 MH-ED 28/Mogul 175/16,000 MH-Pulse Start-ED28/Mogul 250/20, /20,000 MH-ED 28/Mogul MH-Pulse Start-ED28/Mogul 320/30,000 MH-Pulse Start-ED 28/Mogul 400/36,000 MH-ED 37/Mogul 400/42,600 MH-Pulse Start-BT-28/Mogul Approx.

The base shall also include a code for the installer to indicate the installation date of the lamp. 2.5 The lamp shall be constructed of hard glass which shall be designed for an operating temperature up to 400 C. or as otherwise required by ANSI standards for the lamp being furnished. 2.6 The lamp base shall be designed for an operating temperature up to 210 C. or as otherwise required by ANSI standards for the lamp being furnished. 2.7 Lamps meeting current US Environmental Protection Agency s guidelines of Toxicity Characteristic Leaching Procedure (TCLP) for non-hazardous waste (or State of Tennessee requirements of the same guidelines, if more stringent) will be acceptable but are not required. 2.8 The lamp warranty shall be based on 12 hours per start per day operating cycle. 2.9 The high pressure sodium lamp shall be consist of a single arc tube unless specified otherwise in the request for proposal The high pressure sodium lamps shall have arc tube manufactured of PCA (polycrystalline alumina) tubing The color rendering index of high pressure sodium lamps shall be a minimum of 21 unless otherwise required by the request for proposal High color rendering index high pressure sodium lamps shall have a minimum CRI of Dual arc tube high pressure sodium lamps shall be of the same size and operate on the same ballast with the same lumen output as the single arc tube lamp. The dual arc lamp shall have instant re-strike capabilities for the first 24,000 hours of average life. The lamp shall be of the monolithic arc tube design. The two monolithic arc tube shall be mounted in parallel and provide 40,000 average hours of life. Dual arc tube lamps of other designs may be acceptable if the bid contains endorsements by other electric utilities and pre-qualification requirements have been met The metal halide lamp shall be of the universal burning position The color rendering index of metal halide lamps shall be a minimum of The metal halide lamp shall be designed to operate in an enclosed type luminaire. However, lamps designed to operate in an open type fixture will be acceptable Lamps which convert high pressure sodium to metal halide shall operate on existing high pressure sodium systems with an external ignitor requiring no modifications to the luminaire. The CRI shall be a minimum of 65. 3

4 3.0 INFORMATION TO BE RETURNED 3.1 The supplier s quotation shall include the information listed below. 3.2 Shipping date from the supplier s facility. 3.3 List exceptions to this specification (or notations on drawings or catalog cuts of exceptions to this specification). 3.4 At a minimum, the manufacturer s warranty shall provide for proportionately credited lamps which fail to operate according to the following interval based on the manufacturer s date code on the base of the lamp: Operating Intervals Upon receipt First Year Second Year Third Year Credit d on 4500 Hours/Year Operation Fully Credited Two (2) lamps for every failure One (1) lamp for every failure One (1) lamp for every two (2) failures 3.5 To pre-qualify for a NES request for quotation, the manufacturer must present technical information indicating that the lamp meets the requirements specified here-in, three lamp samples, and recommendations from three utilities purchasing the lamps, on more than one occasion. The utility recommendations must include the name and phone numbers of the utility representatives. 4.0 NES POLICY 4.1 NES reserves the right to reject any or all quotations. 4
