LED LUMINAIRE
1.Description.
Fabricate and furnish LED luminaires.
2. Materials.
Provide new materials that comply with the details shown on the plans,
and the requirements of this Item.
Provide 6 sets of submittals for the complete assembly to the Engineer at the project
address. Obtain the Engineer’s approval on the submittals before purchasing materials
and beginning work.
Provide LED roadway luminaire with IES type II light distribution pattern.
General Requirements:
A.
Provide LED luminaires UL listed to UL1598 and suitable for use in wet locations.
Ensure that optical compartment meets IEC Standard 60529-IP65. Place permanent
labels inside of luminaire indicating date of manufacture, IP rating, and UL listing.
Rate luminaire for a minimum operational life of 60,000 hours, with operating
temperature rated between -30 degrees C and 40 degrees C.
Housing:
B.
Provide luminaire housing, lens frame, and door from 96% copper-free, die-cast
aluminum. Provide for luminaire mounting to a 2-in. pipe arm, capable of adjustments
±5° from level. Meet ANSI 136.31, 3.0 G vibration requirements.
Equip luminaire with a three-prong photocell receptacle with shorting cap installed.
Paint luminaires to match the black color finish of the illumination pole or as directed.
Use a thermoset powder-coat paint system.
Fabricate hardware, brackets, nuts, bolts, washers, ballast tray, and parts from
stainless steel or aluminum of adequate thickness as approved.
Ensure weight of the luminaire is less than 40 pounds and the effective projected
area is less than 1.0 sq. ft.
