Rectangular electronic fluorescent ballast in metal housing with wiring terminals

Lumapro

Lumapro Electronic Fluorescent Ballast 108-112W 4 Lamp T8

SKU CH-HHJH-D7T9M

Electronic fluorescent ballast powers four T8 lamps at 108 to 112 watts with instant start on 120 to 277 volts

  • Instant start at 120–277 V AC for reliable ignition
  • Powers four T8 lamps up to 40 W each
  • Supports 17 W, 25 W, 28 W, 32 W and 40 W tubes
  • CA Title 20 compliant for regulated markets
  • Starts down to 0 °F in cold environments

ZORO SELECT 4KGF6 Electronic Ballast

This ZORO SELECT electronic fluorescent ballast drives three or four T8 lamps at 108 to 112 watts. It accepts a wide 120 to 277V AC input and supports bulb wattages of 17, 25, 28, 32 and 40 watts. The unit is CA Title 20 compliant and carries a California Proposition 65 warning for chemicals known to cause cancer and reproductive harm. It suits commercial or residential fixtures needing instant-start operation.

Thermals Noise and Power Draw

The ballast operates with an instant start type and no dimming function, drawing up to 112 watts across the supported lamp range. It is rated for a minimum starting temperature of 0 degrees F, ensuring reliable ignition in cold environments. With no moving parts, it runs silently and generates minimal heat during normal operation. The electronic design maintains efficient power conversion across the full input voltage span.

Sustained Load Behavior

Under continuous operation the ballast delivers stable current to all four lamps without flicker or cycling. The lack of dimming circuitry means output remains constant for the life of the lamps. Its wide voltage tolerance allows consistent performance even if supply voltage fluctuates between 120 and 277V AC. This makes it suitable for installations where lights run for extended periods.

Questions about this item

How do I wire the Lumapro ballast for four T8 lamps on a 120-277 V AC supply, and which step is often missed?

Connect the black and white leads to line voltage, then match each lamp's red and blue sockets to the labelled pairs; the step most installers skip is grounding the metal case to the fixture's green screw.

What component will need replacement first after years of continuous operation?

The internal electrolytic capacitors degrade with heat cycles; when lamps flicker or fail to start instantly, the ballast itself must be replaced.

At what wattage per lamp does the ballast hit its thermal limit during sustained use?

The 108-112 W total rating means four 28 W lamps run at the design maximum; exceeding 32 W per lamp pushes the case temperature past its rated rise.
