Choosing the right ballast is essential because system performance is dependent on the interaction between the lamp and ballast.
Here is why:
As elements in an electrical circuit, germicidal lamps are referred to as “active” elements because they generate harmonic and transient voltages and currents. They exhibit a seemingly strange characteristic – the voltage decreases with increasing current. This process is known as negative AC resistance. Therefore, gas discharge devices, such as germicidal lamps, are inherently unstable; once lit, the current increases without limit unless other circuit elements – ballasts – are used to restore and maintain operation.
At Light Sources and LightTech, we have available a number of electronic ballasts that match our lamps. If you need help with a ballast- give us a call and we will help you to match the ballast to the lamp. Germicidal Sales: (203) 799-7877.
