Warranty Statement

Cosine Lighting, LLC warrants that its LED Products (excluding drivers or other integral control system devices) are free of defects in workmanship and materials for a period of FIVE YEARS from the date of shipment. Operation of LED Products above the maximum ambient temperature range noted on product specification sheet will void this warranty. Maximum ambient temperature is defined as the maximum temperature of the air surrounding the luminaire housing. Products that do not have maximum ambient temperatures listed on specification sheet must operate in ambient conditions at or below 25-degrees Celsius. LED Products will be considered defective in workmanship or material only if the LED Products fail within 5-years after shipment to provide at least 70% of the lumen output set forth in the product specification sheet as of the date of shipment. Drivers or other integral control system devices may be covered by separate manufacturers’ warranties. Cosine Lighting does not make any warranties whatsoever as to drivers or other integral control system devices and will accept no responsibility or liability whatsoever.

This Limited Warranty may not be transferred or assigned by the original end user. Cosine Lighting, at its sole option, will repair or replace any Cosine Lighting warranted product deemed defective in workmanship or materials, and such repair or replacement is the sole and exclusive remedy against Cosine Lighting for failure of the Product(s) to comply with the terms of this Warranty and does not extend the Warranty period.

Cosine Lighting is not responsible for any costs and expenses incurred in connection with shipment of Product(s) to Cosine Lighting, but shall bear all cost and expense incurred in connection with shipment of replacement Product(s) to the customer. This warranty does not include labor or equipment to remove or install fixtures or failed components. No charge back, or charge for labor or material, that does not have Cosine Lighting’s prior written approval will be honored, accepted or paid by Cosine Lighting. If Cosine Lighting chooses to replace the Product and is not able to do so because it has been discontinued or is not available, Cosine Lighting may, at its sole option, refund the purchase price or replace the Product(s) with a comparable product (that can show immaterial deviations in design and product specification). Cosine Lighting will not be responsible under this Limited Warranty for any failure of the Product(s) that results from external causes such as: acts of nature; physical damage; exposure to adverse or hazardous chemical or other substances; use of reactive cleaning agents and/or harsh chemicals to clean the Product(s); environmental conditions; prolonged storage in adverse temperatures; vandalism; fire; power failure, improper power supply, power surges or dips, and/or excessive switching; induced vibration; animal or insect activity; fault or negligence of purchaser, any end user of the Product(s) and/ or any third party not engaged by Cosine Lighting. Improper or unauthorized use, installation, handling, storage, alteration, maintenance or service, including failure to abide by any product classifications, certifications or specifications, or failure to comply with any applicable standards, codes, recommendations, product specification sheets, or instructions of Cosine Lighting, use of the Product(s) with products, processes or materials supplied by any end user or third party; or any other occurrences beyond Cosine Lighting’s reasonable control shall void this warranty. Cosine Lighting also will not be responsible under this Warranty for any substantial deterioration in the Product finish that is caused by failure to clean, inspect or maintain the finish of the Product(s). Adequate records of operating history, maintenance, and/or testing must be kept by the end user and provided to Cosine Lighting upon request to substantiate that the Product(s) have failed to comply with the terms of this Limited Warranty. Neither polycarbonate nor acrylic material used in the Products is warranted against yellowing, as yellowing may naturally occur over time due to normal aging. The Product(s) are not warranted against costs that may be incurred in connection with changes or modifications to the Product(s) required to accommodate site conditions and/or faulty building construction or design. This Warranty is not applicable to any Products which are not installed and operated in accordance with the current edition of the National Electric Code (NEC), the Standards for Safety of Underwriters Laboratory, Inc. (UL) or Intertek (ETL), or the standards for the American National Standards Institute (ANSI) and with Cosine Lighting’s instructions and guidelines for the Product. Warranty claims regarding the Product(s) must be submitted in writing within thirty (30) days of discovery of the defect or failure to an authorized Cosine Lighting customer service representative. Product(s) or component part(s) may be required to be returned for inspection and verification of non-conformance by Cosine Lighting.
