Existing products can often be upgraded, extending their useful lifetime tremendeously. Here you can find conditions and instructions for product upgrades.

Products which have been regularly purchased from Lightning (this includes all products which have been duly purchased from Lightning directly or indirectly) are eligible to upgrades when available. This is an additional protection offered to our customers.

We will need from the owner of the units:

• An order with specifying which upgrade(s) are purchased
• The serial number of the units
• A copy of the invoice or proof of purchase

These information can be submitted to the original official seller of the products, which will forward them to Lightning.

Please allow 2-3 working days for processing regular upgrade requests.
