Warranty + Sales Terms and Conditions

Returns, Terms & Conditions, and Warranty Policy

Sales Policy

All sales are final. We are committed to customer satisfaction, but due to the sensitive nature of horticultural environments, we cannot accept returns due to mold, pests, or similar issues. Exceptions may be made for items damaged in transit or with confirmed manufacturing defects. Please contact us for case-by-case review.


Authorized Returns

If a return is authorized within 30 days of delivery, a restocking fee of 20% or more may apply, and all shipping costs are the responsibility of the customer. No returns will be accepted after 30 days. All return approvals and terms are at the sole discretion of Mammoth Lighting LLC and may be updated at any time.


Shipping & Customs

Customers are responsible for all shipping fees, import duties, taxes, and customs clearance. Mammoth Lighting LLC provides documentation to assist with customs processes but is not responsible for delays, costs, or returns due to customs issues. Insurance is highly recommended and available upon request. We are not liable for lost, damaged, or stolen shipments once they leave our facility unless otherwise agreed in writing.


Shipping Liability

All shipments are sent with limited carrier insurance (typically $100) and no signature required unless arranged in advance. Mammoth Lighting is not liable for loss, theft, or damage once the package is in the hands of the shipping carrier.


Limited 5-Year Warranty Policy

Warranty Coverage

Mammoth Lighting LLC offers a 5-year limited warranty to the original purchaser against manufacturing defects in materials and workmanship. Coverage includes:

5-Year Warranty Coverage

  • Full light fixture (frame and wiring)

  • Structural components

3-Year Warranty Coverage

  • LED drivers

  • Control panels

  • Individual light bars

1-Year Warranty Coverage

  • UV modules and other specialty lighting accessories

    • 100W Single Bar

    • Controllers / PAR Meters

    • Clone Inter-canopy Light


LED Diode Coverage

Light bars will only be eligible for warranty replacement if 5% or more of the total diodes on an individual bar have failed. This threshold ensures realistic and fair service coverage for minor anomalies.


Warranty Eligibility & Service

  • Warranty applies only to the original purchaser and is valid for products bought from Mammoth Lighting or an authorized dealer.

  • Coverage is void if the product is resold, modified, improperly installed, or mishandled.

  • Within the first year, Mammoth Lighting will provide replacement parts at no cost (excluding labor and shipping).

  • After year one, customers are responsible for shipping and any costs for non-covered parts.

  • Labor is not included under any part of this warranty.


Exclusions

Warranty does not cover damage due to:

  • Improper installation, use, or maintenance

  • Physical damage, abuse, or neglect

  • Water intrusion or exposure to corrosive substances

  • Power surges or tampering with electrical components

  • Natural wear-and-tear beyond expected use


Supplier Clause

Mammoth Lighting sources premium components, but cannot guarantee indefinite availability of every part. In the event that a key supplier discontinues or becomes unable to provide parts:

  • The warranty for affected components will be voided.

  • At Mammoth Lighting’s discretion, we may offer prorated credit, replacement parts, or discounted new fixtures, based on the time remaining in the original warranty.

  • Mammoth Lighting will make reasonable efforts to offer suitable alternatives but is not obligated to replace discontinued or unavailable parts beyond the original supplier’s failure.


Repair & Return Procedure

To request warranty service:

  1. Email sales@mammothlighting.com with a description of the issue, product serial number, and photos/videos.

  2. If approved, you will receive return instructions.

  3. Customers are responsible for all inbound shipping costs. We recommend insuring shipments.


Limitation of Liability

Mammoth Lighting LLC is not liable for incidental or consequential damages, including but not limited to crop loss, labor, revenue, or downtime. Our responsibility is limited solely to the repair or replacement of defective components per the warranty terms.

Failure to pay invoices in full at time of delivery may void all warranty rights. This written policy supersedes all other warranties, whether express or implied.
