Warranty + Sales Terms and Conditions

Returns and Terms & Conditions:

Sales Policy: All sales are considered final. We are committed to customer satisfaction, and while we regret that we cannot accept returns due to issues related to mold or pests, we may consider exceptions for other circumstances such as defects or damages during shipping. Please contact us with any questions or concerns.

Authorized Returns: If a return is authorized within 30 days from the date of purchase, a restocking fee of 20% or more, along with shipping costs, may apply. Returns will not be accepted after 30 days. All terms and conditions are at the full discretion of Mammoth Lighting LLC and are subject to change.

Shipping and Customs: Customers are responsible for all shipping charges, customs clearance, taxes, and duties associated with the importation of purchased products. While we facilitate customs clearance by providing necessary documentation, we are not liable for delays or additional costs incurred during the customs process or for any resulting returns.  We recommend insuring products during shipping to protect against damage or loss, for which we are not liable. 

Shipping Liability:   Shipping is out of our control once it leaves our warehouse.  If you need insurance, please contact us before shipping, as we ship with limited ($100) insurance and no signature required.  Lost or stolen items we are not liable.  


Warranty Coverage: Mammoth Lighting LLC stands behind the quality of our products. We offer a 1-year warranty from the date of purchase for most products, with select items covered by a limited 5-year warranty. Please note that UV lights come with a 1-year warranty.  Power drivers and control panels are covered for 1 year, light bars for 3 years, and fixtures + components for 5 years.

Warranty Terms: Warranty coverage applies exclusively to the original owner and the original product. It is not transferable and does not cover refurbished or used lights. Defects within the specified warranty period, not resulting from user error or improper use, may be eligible for repair parts at the discretion of Mammoth Lighting LLC.

Warranty Service: Within the first year, Mammoth Lighting LLC will provide repair parts at no additional charge to the purchaser (excluding shipping costs) for defects related to our manufactured products. After the first year, repair parts plus shipping costs may be incurred.

Warranty Exclusions: Mammoth Lighting LLC is not responsible for damages resulting from physical damage, product modifications, misuse, inappropriate installation, handling, or packaging.

Shipping and Liability: Customers are responsible for prepaying all inbound freight charges for both warranty and non-warranty repairs. We recommend insuring products during shipping to protect against damage or loss, for which we are not liable.

Limitation of Liability: In no case is Mammoth Lighting LLC liable for consequential damages, including lost profits or business, even if informed of the potential for such damages.

Additional Notes: This warranty policy is the sole authorized warranty by Mammoth Lighting LLC and supersedes any implied warranties. Mammoth Lighting LLC reserves the right to waive its warranty policy if payment of the invoice is not made in full upon delivery.

Instructions for Returning Products for Service: Customers must email detailed information, pictures, and videos to sales@mammothlighting.com for assistance with returns or warranty claims.

No Liability for Consequential Damages: Under no circumstances shall Mammoth Lighting LLC be liable for any special, incidental, or consequential damages.

UV Radiation Safety Disclaimer

Notice to All Users:

Please be aware that certain grow lights sold on this website may emit ultraviolet (UV) radiation, which includes UVA wavelengths. While UV radiation is a natural component of sunlight and can have beneficial effects on plant growth, it is important to understand that exposure to UV radiation can pose health risks.

Health Risks of UV Radiation:

  • Skin Exposure: Prolonged or intense exposure to UV radiation can lead to skin damage, premature aging, and an increased risk of skin cancer.
  • Eye Safety: Direct or prolonged exposure to UV radiation can cause eye discomfort and damage, including conditions such as photokeratitis or cataracts.

Mandatory Use of Personal Protective Equipment (PPE): To ensure your safety and the safety of those around you, it is mandatory to wear appropriate personal protective equipment (PPE) when operating grow lights that emit UV radiation. This includes, but is not limited to:

  • Protective Clothing: Cover skin with clothing or special protective gear to minimize direct exposure to UV radiation.

Safe Operation Guidelines:

  • Follow all manufacturer instructions regarding the safe operation and installation of grow lights.
  • Do not look directly at the light source when the grow lights are in operation.
  • Limit time spent in close proximity to the lights while they are turned on.

By purchasing and using grow lights from our website, you acknowledge the potential risks associated with UV radiation and agree to adhere to all safety precautions and guidelines. Failure to comply with these safety measures can result in serious health risks.
