All of our Viqua UV Lamps (Bulbs) are in the original Viqua white box with clearly indicated branding, serial number, part number and the manufacturer's bar code. The lamp is marked with a Viqua stamp and is packaged securely wrapped in bubble wrap inside the box. Included are the instructions for replacing the lamp. See the related images for a picture of the white box with branding. If your lamp does not have this packaging, it is NOT a Genuine Viqua product and could be a knock off brand that would void your system warranty.
