Capacitor, Metal Halide, 1000W/Wet 24 MFD/480 VAC MIN

Replace the Capacitor in Your Hydrofarm 1000W Metal Halide Magnetic Ballast

Capacitors in HID magnetic ballasts store electrical charge and release it to handle the high initial current demand during lamp ignition and startup. Over time, capacitors degrade — losing their charge-holding capacity and eventually causing ballast failures, lamp startup problems, or inconsistent light output. Replacing a faulty capacitor restores normal ballast function at a fraction of the cost of a full ballast replacement.

This Hydrofarm 1000W metal halide capacitor is rated at 24 MFD and 480 VAC minimum, wet type — specified for all Hydrofarm 1000W metal halide magnetic ballasts. Capacitors are rated to specific values; always match the replacement to the original specification before installing.

Key Features & Benefits

• 24 MFD capacitance — rated at 24 microfarads — the specified capacitance for Hydrofarm 1000W metal halide magnetic ballasts.
• 480 VAC minimum voltage rating — rated for the voltage levels present in 1000W metal halide ballast circuits.
• Wet type construction — wet electrolytic capacitor construction suitable for the operating conditions of magnetic HID ballasts.
• Hydrofarm 1000W MH ballast compatible — specified for use in all Hydrofarm 1000W metal halide magnetic ballasts.
• Restores ballast function — replacing a degraded or failed capacitor can restore normal lamp startup and consistent light output without replacing the entire ballast.

Who Should Use the Hydrofarm 1000W Metal Halide Replacement Capacitor

Growers with Hydrofarm 1000W metal halide magnetic ballasts experiencing lamp startup failures, inconsistent output, or other symptoms of capacitor degradation who need a replacement capacitor matched to the ballast's specifications.

How to Identify a Failed Capacitor

Common signs of a failing capacitor include lamps that fail to ignite or take longer than normal to start, flickering or inconsistent light output, and ballasts that run hotter than usual. A failed capacitor can also produce a bulging or leaking case on visual inspection. Always discharge and de-energize the ballast before replacing any internal components.

Frequently Asked Questions

How do I know if my capacitor has failed?

Symptoms include lamp startup failure, extended warm-up time, flickering, and abnormal ballast heat. A multimeter with a capacitance setting can measure the actual capacitance — if it reads significantly below 24 MFD, the capacitor has degraded.

Can I use this capacitor in a non-Hydrofarm metal halide ballast?

This capacitor is specified for Hydrofarm 1000W MH magnetic ballasts. Other ballasts may use different capacitance values or voltage ratings. Always match the replacement capacitor to the original specification from the ballast manufacturer.

Is it safe to replace a capacitor myself?

Capacitors store charge and can deliver a dangerous shock even after the ballast is unplugged. Always fully discharge the capacitor before handling, and allow the ballast to sit unplugged for several minutes. If you are not comfortable with electrical work, have the replacement done by a qualified technician.

Should I replace the ignitor and capacitor at the same time?

If the ballast has had lamp startup issues for an extended period, replacing both the capacitor and ignitor together is a common practice — since both components wear together. Replacing one while leaving the other allows the remaining worn component to cause future failures.
