Here's a breakdown of our policy on returning items: Within a 7 day period since you physically received your light (in accordance with the tracking information provided with your order) we will accept your return.

If the problem is not related to quality or functionality (i.e. it won't turn on/off, has a defective bulb/wiring), all buyers will need to pay any return shipping costs from a direct shipping company (like UPS or FedEx) to our warehouse from your home and we will charge 20% of the total amount for repacking. We also request that you return the product in the original packaging with a receipt of purchase.

Return Procedure

You will receive your refund through your debit or credit card as soon as we've received the product and can ensure that it's in good condition. As long as you return the product within one week (7 days), we have no problems returning your money to you as long as the reason for your request is reasonable.

Unfortunately, there are some conditions in which we will not accept returns

-Any product returned over a seven day period.

-If the light has been used or shows signs of use and works as promised.

-If there is no proof that your plants could have died as a direct result of our lights.

-If our model is updated within the time that you purchase a product and the time you return it. Unfortunately we do not back-stock old items.

-If your model is broken (and it's your fault).

-If we've improved our item, and you wish to return yours, we cannot accept your return (typically the prices are higher).


If you insist on returning your package after the 7 day return policy, there are a few stipulations. Customers will need to pay a delayed return fee, in accordance to the following policy:


-Within a month of the original week period and your purchase is in good condition: 20% delay fee

-Over one month late but less than three months past return period (and if the light is unused): 40% delay fee. If the light is used, we take between 50 and 70% of the purchase cost of the light, based on the condition in which we receive it.

-If you hold the light for more than three months, but within six, we'll refund 20% of a light that works well.


We cannot accept lights that have been purchased over a half a year ago whether you've used the light or not. We apologize for the inconvenience.
