VIQUA S212RL Replacement UV Lamp for VIQUA VT1 system

I purchased two of two and what I got were not genuine Viqua Sterilight but knock-off that barely put out any light. They used a play on words of " Viqua Sterlight Replacement Lamp" and yes it is a replacement for Viqua Sterlight but they are or not from Viqua Sterlight. I returned them and got a refund two months later and purchased the lamp from where i originally purchased the RO system.
