PART 2 – SPECIFICATIONS

A. Warranty: The electrical designer must include the following paragraphs in the electrical section of project specifications:

1. Ballasts and lamps shall carry five-year warranties as described below, including labor allowance.



2. The contractor shall be responsible for replacement of all defective lamps and ballast for a period of one year from the date of acceptance. During this one year period, the contractor shall respond to the owner's request to replace defective lamps and ballasts within one week of receipt of the request. A failure of five lamps or ballasts, or failure of any lamp or ballast in sensitive areas will cause a service call.

3. One month before the end of this one-year period, the contractor shall make a facility wide survey to identify and replace all defective ballasts and lamps. The contractor shall provide the owner written notice of this survey and warranty replacement two weeks prior to the survey. In the event that the contractor fails to accomplish this facility-wide survey to identify and replace all defective ballasts and lamp, the initial warranty shall be extended until such time as the contractor fulfills the survey requirements.

4. For the second through fifth year after acceptance, the ballast shall be covered by a full replacement warranty and a $10 per ballast installation allowance. (This is the standard warranty provided on electronic ballasts by several manufactures.)

B. Removal of existing ballasts: The electrical designer must include the follow paragraph in the electrical section of project specifications:

1. Renovation projects in which existing light fixtures are to be removed, it shall be the responsibility of the contractor to remove and dispose of all PCB ballasts. Disposal shall be in accordance with EPA Regulation 40CFR-761.

LX–SERIESAluminum Dome

For style, functionality and energy efficiency, the LX AluminumDome High-Bay from Sportlite provides maximum down-light that isperfect for warehouses, gymnasiums, ice rinks, manufacturingplants or any application requiring flexible high-bay style fixtures.The LX800 with 42 watt compact fluorescent lamps (CFL) suppliesan impressive 25,600 lumens and 85 percent lumen maintenance.

Stylish EffectSportlite offers a stylish alternative to standard metal

reflector-type HID fixtures with the new LX800 Aluminum DomeHigh-Bay. Featuring an eye-pleasing aluminum ballast housing andreflector, the LX Series provides very even vertical and horizontalfoot-candles, which are highly desirable for televising sportingevents and providing surface light to more effectively sell products,The LX Series reduces the glare often associated with standardHID high-bay fixtures.

Mood LightingThe LX Series sets the tone for any application, offering a wide

variety of lamp color temperatures to create the desired effect ormatch existing lighting. These high-CRI (82-84) lamps produce a

more natural lighting effect. The LX Series provides comfortableeven light, a larger light spread, minimal shadowing and nostroboscopic effects. With maximum lumen output at 30 degrees,the LX Aluminum Dome produces and efficient “batwing”photometric configuration, which creates a very smooth lightingpattern and a favorable spacing to mounting height ratio.

Smart & FunctionalThe LX Series offers smart features for simple and safe use. Its

modular construction featuring “AMP” snap lock electricalconnectors and “spring-clip” secured ballasts allows easyinstallation and maintenance with minimal tools The “instant on”feature allows control over pairs of lamps within an individualluminaire. Choose sensor-controlled, four level stepped dimmingfor an efficient and inexpensive way to lower light levels and saveenergy without changing the photometrics.

Energy EfficientThe energy saving, compact fluorescent LX800 Designer

High-Bay is a must-have replacement for the high energyconsuming, old standard HID style high-bay fixture. Realize anaverage 25 to 40 percent energy savings compared to 400 watt HIDfixtures. Eliminate hot spots and color shifts typical of metal halidelighting fixtures.
