Fulham WH8-120-L Ballast

The Fulham WH8-120-L is an electronic fluorescent ballast designed for commercial and outdoor lighting systems. It operates on 120V AC input and supports one to six lamps with a total power range of 13 to 220 Watts. The unit uses instant start technology and is rated for a minimum starting temperature of -22 degrees Fahrenheit. It is compatible with T12, T5, T8, and T8U bulb types across multiple wattages.

Upgrading from magnetic ballasts

This electronic ballast replaces older magnetic ballasts to eliminate flicker and reduce energy consumption. The jump is worth it when fixtures require support for multiple lamp configurations or operation in cold environments down to -22 degrees Fahrenheit. It also removes the need for separate starters used in preheat magnetic systems. Buyers who need dimming capability should look elsewhere because this model provides no dimming function.

Check your existing setup

Verify that the supply voltage is 120V AC and that the installed lamps match the supported types and wattages listed. Confirm the fixture wiring suits an instant start ballast with no dimming requirement. Ensure the ambient temperature does not fall below the rated minimum starting temperature. This product contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm.

Questions about this item

What wiring space is required for the 120V AC input on this ballast?

The unit accepts a 120V AC supply and supports instant start for one to six lamps, so allow conduit room for the incoming line and up to six lamp leads.

Which step is often missed when wiring the instant-start ballast to multiple T8 or T5 lamps?

Connect each lamp holder to the correct output lead for the programmed wattage; skipping the lamp-type selection link causes incorrect starting voltage.

When should the ballast be replaced if it operates down to -22 °F?

Replace the ballast when lamps flicker, fail to start at the rated minimum temperature, or when the unit exceeds its 13 to 220 watt operating range.
