r"- R The Leader in Electro-Optics Technology <br />i <br />LEOI i_I: LEOTEK Electronics <br />USA Corp. <br />a subsidiary company of LITEUI ? I <br />Proposed Products: <br />Leotek is offering the following products for this bid: <br />726 South Hillview Drive, Milpitas, CA 95035 <br />Tel: (408) 380-1788 Fax: (408) 518-8128 <br />E-mail: sales@leotek.com Website: www.leotek.com <br />• To replace 250W HPS street light - Leotek # GC1-80E-MV-NW-3-GY-700 <br />• Factory or field installable house side shield plate accessory - HSS-80 <br />• To replace 40OW HPS street light - Leotek # GC2-120E-MV-NW-3-GY-700 <br />• Factory or field installable house side shield plate accessory - HSS-120 <br />Alternate 25OW HPS Proposal (explained below #3 Note): <br />• To replace 250W HPS street light - Leotek # GC1-80E-MV-NW-2-GY-530 <br />Product Availability: <br />Normal delivery on the proposed products is 6-7 weeks after receipt of order. <br />Notes Pertaining to Specification: <br />1) The proposed 40OW HPS replacement, Leotek # GC2-120E-MV-NW-3-GY-700 fully meets the <br />specification requirements for the City of Santa Ana with the exception of the required 140 watt <br />max, 80 lumen per watts, and max B2U2G2. (This unit has B3 UO G3) <br />2) The proposed 250W HPS replacement, Leotek # GC1-80E-MV-NW-3-GY-700 fully meets the <br />specification requirements for the City of Santa Ana with the exception of the required 140 watt <br />max, 80 lumen per watts, and max B2U2G2. (This unit has B3 UO G3) <br />3) Based on the pole locations indicated on the 'Map Data', Leotek is offering as alternative <br />proposal for the 250W HIPS replacement of model # GC1-80E-MV-NW-2-GY-530. Although at <br />74 lumens per watt, the system efficacy of this unit is slightly below the specified 80 Ipw, the <br />total wattage is still below the maximum allowable 140W. Also, this unit meets the max BUG <br />rating with B2 UO G2. <br />Furthermore, after performing the lighting calculation per the lighting criteria provided, it shows <br />that the Type 2 optical system of this alternate unit will provide better lighting uniformity than the <br />specified Type 3. It is for these reasons that Leotek recommends using this alternate product to <br />replace the existing 25OW HPS luminaires. <br />4) The specification allows for "optional house side cut off'. The shield submitted with the Leotek <br />luminaire is "easily retrofitted to fixture". This has proved to be a significant advantage for <br />addressing the occasional back light complaint without having to change out an entire luminaire. <br />Also, Santa Ana won't have to inventory two different luminaires. Several large Leotek users <br />only find it necessary to stock a few house side shields for those rare applications. <br />5) Santa Ana's specification calls for a "full-cutoff' classification. Please note that our provided LM- <br />79 test report confirms that we do meet this full cutoff classification. Most other manufacturers <br />won't show this on their test reports because they typically fail this test at the 80 degree angle <br />and therefore are not in compliance with the specification. <br />Attachment 1
