Lighting Drivers and Ballasts
Drivers and Ballasts are essential in electrical lamps’ proper starting and operating functions. Drivers are found in LED lights, while ballasts are used in fluorescent lighting systems. Both items limit the amount of current in an electrical circuit and provide sufficient voltage to start the lamp. Without the regulation provided by drivers and ballasts, the electrical current would quickly rise to dangerous levels, causing the power supply to fail. LED emergency drivers regulate the power supply to LED fixtures in the event of a power failure and allow the LED fixture to switch from line voltage to battery when in emergency mode.
Fluorescent Lamp Ballasts
Fluorescent light ballasts provide the initial high voltage needed to start the fluorescent lamp and regulates the current flowing through the lamp to prevent overheating. The ballast also converts the input voltage to the correct voltage for the light and protects the lamp from damage.
Signs that a fluorescent light ballast may be bad include; the light flickers, turns off frequently, is dim, or has poor color quality. A failing ballast may also make a humming or buzzing noise.
Fluorescent Lamp Ballasts
An LED driver is a device that converts electrical power into a form that can power light-emitting diodes (LEDs). LEDs require a constant current to operate correctly, and the driver ensures that the current is delivered stably and consistently.
The Isolite EMP Emergency LED Driver, an energy solid-state switching power supply, is available in various wattage and volt configurations. The EMP’s long life, thermally safe, high-capacity maintenance-free Lithium Iron Phosphate batteries provide a 90-minute emergency duration and environmentally friendly end-of-life recycling.
