The current flow in a lamp depends on the voltage it is connected to. A simple way to measure lamp voltage is to measure the current flow through a resistor. The internal resistance of a resistor is negligible. It is essential to choose a resistor whose value will operate the lamps at the right voltage.
The X-Series lamps are designed to provide wide-area UV coverage and high-intensity light. They are available in single or double UV tubes, and in a range of wattage and sizes. Their corrosion-resistant aluminum reflector is designed to optimize UV irradiance. They also feature a unique LONGLIFE filter glass for superior protection.
