Rectangular metal HID ballast kit with mounting tabs and wiring leads

Lumapro

Lumapro 4CRH4 350 W 1 Lamp HID Ballast Kit

SKU CH-1EH7-Z7EGN

350 W pulse-start metal-halide ballast kit runs one lamp on 120 to 277 V AC at 60 Hz with a 0.97 ballast factor and starts down to -20 °F

  • 350 W metal halide operation supported by M131 ANSI code
  • Pulse-start ballast ignites lamps reliably at -20 °F
  • Multi-tap 120 to 277 V input suits varied supply
  • 97 ballast factor maintains strong lumen output
  • 397 W input power for efficient single-lamp driving

Purpose and Fit

The Lumapro 4CRH4 is a magnetic HID ballast kit built to drive a single 350 W metal halide lamp. It suits commercial or industrial lighting installations that require a pulse-start ballast operating on 120 to 277 V AC at 60 Hz.

Decisive Specification

The ANSI M131 code is the single figure that confirms compatibility; the ballast will only start and run lamps marked with the same code. Using a lamp with a different ANSI designation will prevent ignition or cause premature failure.

Kit Contents and Effect

The kit bundles the ballast with the components needed for a complete pulse-start circuit, so installers do not source a separate ignitor or capacitor. This reduces wiring time and ensures the 0.97 ballast factor and -20 °F minimum starting temperature are achieved as rated.

Questions about this item

How much power will the ballast draw from the mains when running a 350 W metal halide lamp?

The kit lists an input of 397 W at 120 to 277 V AC, so the circuit must supply roughly 397 watts while the lamp is operating.

What does the ANSI code M131 tell me about lamp compatibility?

M131 identifies the ballast as a pulse-start type for a single 350 W metal halide lamp, so only lamps carrying the matching ANSI code should be used.

What is the coldest temperature at which this ballast can reliably start the lamp?

The minimum starting temperature is rated at -20 degrees F, allowing ignition in unheated outdoor or cold-storage fixtures.
