Whether your order is big or small, it is tested through many run cycles, and each bulb is tested before shipment. Every single bulb. Every time. And if anything does go wrong, you can rely on our industry-leading warranty for worry-free replacement.
If you're not happy with your items, we want to make it right. So we have some pretty awesome return policies:
30 day return policy. All customers have 30 days from the date of original order shipment to return items.
Full refund, no fees. At Diode Dynamics, we offer free returns. That means no restocking fees, no administrative fees, and no hassle!
Free return label. If your original order was over $50, you get a free return label for your items (US customers only). If your order was less than $50 or international, you can send the items back through your preferred method.
Within 30 days: If your original order was over $50, you can get new items shipped to you with a return label (US customers only). If your order was less than $50 or international, we can send you the new items first, but you are responsible for returning the old items.
Within 90 days: Any item can be returned for exchange or store credit within 90 days. The buyer is responsible for the cost of the return shipping, and must first return the old items. We'll still cover the postage for the new items.
Please note: due to the nature of custom acrylic pieces, we cannot offer any refund or exchange for returned custom acrylic items.
To make a return or exchange, please request an RMA, or give us a call. When we get it back, you will be notified and credited appropriately.
Again, all returns must be approved, with an RMA. This is so that we can process your return as quickly as possible when we get it. If you would like to return an item, please Request an RMA. Please include as much information as possible about the reason for return.
Alternatively, you can also send us a message, or give us a call!
