HID Ballast packing box


High Intensity Discharge (HID) lamps require a 400W HPS Ballast to apply starting voltage to the lamp and establish current flow – an arc – between the lamp electrodes. Without a ballast, the arc will extinguish or draw increasing current until some circuit element burns up. Ballasts provide system stability by limiting the current that can be drawn.

Core and Coil 400W HPS Ballast is used in over 20% of all HID lighting. Replacement ballast kits contain the appropriate core and coil, a properly rated capacitor and all components required for ballast replacement.

James Lighting, core and coil, HID ballast kit is ideal for a wide variety of lighting applications, including factories, warehouses, gymnasiums and retail stores.

What is the input voltage range for 400W HPS ballasts?
Most ballasts have a multi-tap feature that allows for use with different input voltages, typically 120V, 208V, 240V, and 277V.

What is the expected lifespan of a 400W HPS ballast?
Typically, Magnetic ballasts can last up to 5-8 years.

Can I use a 400W HPS ballast for a 250W HPS lamp?
No, you need to use a ballast specifically designed for the wattage of your lamp.

Can 400W HPS ballasts be used with different types of lamps?
No, you need to use a ballast specifically designed for the type of lamp you are using.

What is the maximum distance between the 400W HPS ballast and the lamp?
The maximum recommended distance is usually around 15 to 20 feet.

How do I wire a 400W HPS ballast?
Refer to the manufacturer’s wiring diagram for proper installation.

Is it necessary to ground a 400W HPS ballast?
Yes, grounding is essential for safety and proper operation.

What is the operating temperature range for a 400W HPS ballast?
Most ballasts can operate within a temperature range of -40°C to 50°C.

Can a 400W HPS ballast be used for outdoor lighting?
Yes, but you need to use a weatherproof enclosure to protect the ballast from moisture and dust.

What is the difference between magnetic and electronic ballasts for 400W HPS lamps?
Electronic ballasts are more efficient, produce less heat, and have a longer lifespan than magnetic ballasts.
