What doesn’t our warranty cover?
In any instance where your bulb has developed a fault, we will do our utmost to replace it or offer a full refund (provided the item is still within its stated warranty period). However, if it becomes apparent that the product has been misused, tampered with or modified in any way, we will view this as having voided its warranty.
‘Misuse” includes, but is not limited to, incorrect operation by the user, use of non-dimmable bulbs on a dimmable circuit or connection to or operation with an unsuitable power supply. ‘Tampering’ or ‘modification’ can be interpreted as any activity designed to alter the product in such a way that it can be used in a manner that wasn’t intended by its original design. This can include rewiring, removing plugs, home repairs or changing components. Unfortunately, we won’t be able to replace any item that has undergone any such process.
