According to the feedback from our distinguished customers, some lights are not available to send to the service center for warranty repairing when insignificant growing stage. We would like to offer you used replacement lights in order to make the repair proceed temporarily. Used replacement lights conditions listed as below:

A. We will charge a deposit before sending the replacement light out.

B. You will cover the shipping fee of the replacement light to & from the service center.

C. You must send back the replacement light in one week after receiving the fixed light.

1. If the light has been tampered with or it is found that damage is caused by the customer, there will be a repair fee to pay. If the warranty seal is broken without our consent, your warranty becomes void. If damage has been caused by abnormal use, neglect (such as dripping water), wrong input voltage, dropping or breaking the light, disassembling light, etc., the warranty is void. Warranty coverage is ultimately left to the discretion of Mars Hydro. We reserve the right to refuse warranty repair or replacement service to anyone.
