* Bulbs cannot be warrantied because factors such as input voltage fluctuation, age of original UV device electronics, damage to power supply in the UV housing or power spikes and surges can cause any lamp to fail. Make sure the bulb you are replacing is not due to a failure of your UV system electronics or power supply
