Electronic Ballast for T8 Fluorescent Fixtures

This electronic ballast operates T8 lamps at 120 to 277 volts AC and supports two or three bulbs. It accommodates lamp wattages of 17, 25, 28, 32 and 40 watts with an instant start method. The unit draws 83 to 85 watts total and meets California Title 20 efficiency requirements.

Steady Output Across Supported Lamps

Instant start ignition lights lamps without delay or flicker at the rated minimum starting temperature of 0 degrees F. The ballast maintains consistent power delivery across the 17 to 40 watt T8 range during continuous operation. No dimming function is present, so light output remains fixed at full brightness for the duration of use.

Commercial-Grade Housing for Indoor Mounting

The ballast carries a California Proposition 65 notice for chemicals linked to cancer and reproductive harm. It is built for indoor installation in standard fluorescent fixtures where the 120 to 277 volt supply is available. The absence of dimming leads simplifies wiring to a basic two-wire connection per lamp holder.
