Orders will ship within one business day. Whenever possible, we will ship orders the same business day. You will not be billed until the order ships.

International - Shipping
International shipping times vary greatly, but please allow at least 30 days for an international order to arrive. While many orders arrive within 10-15 days. It is not uncommon for them to require 30-45 days especially during peak seasons.

All our products include a 30 day return policy. All returns must include the original packaging. Return shipping is the responsibility of the buyer unless KMS² is at fault, such as a defect or shipping error.

International or premium shipping charges will not be refunded unless an error by KMS² is responsible for the return. You must contact us to receive approval prior to returning the item.

Once we receive and inspect the returned item we will issue a refund. If there is damage due to mishandling, we reserve the right to deduct a restocking fee.

Note: A restocking fee will only be charged in cases where the product was clearly abused and not returned in good faith. Put simply, we understand an installed product won’t come back perfect, but if it is clear that the item was broken due to negligence, this fee may apply.


All of our lighting products include a lifetime warranty for the original owner against manufacturer defects. Other products, such as power supplies and switches are warrantied for a period of 60 days from the date of purchase.

Warranty replacements will be zero cost for the first 12 months from date of purchase. After 12 months, the replacement is free. However, the shipping is the responsibility of the buyer.

In order to file a warranty claim, we require your order number. Without this information we will be unable to fulfill your warranty request.

If your light is already installed; do not remove it until requested to do so. Using our contact page; provide the requested information.

We will contact you at the provided email within one business day with instructions on the next steps. Our goal is to make this process as painless as possible. However, we will need to determine the cause of the failure to ensure our manufacturing process is maintaining the quality standards that we demand.
Note: Removal of the light prior to contacting us does not void the warranty. Often the issue isn't related to the LEDs and removal is unnecessary. LED failure due to defects is extremely rare with our lights.
