Product Identity

The Fulham WH1-120-L is an electronic fluorescent ballast designed for 120V AC input. It supports a single T5 or T6 lamp with power ratings from 4W to 42W. This component suits maintenance crews and installers servicing commercial or traffic lighting fixtures.

Lamp Compatibility

The decisive specification is the supported lamp range: one T5 or T6 bulb rated at 4, 6, 8, 13, 14, 21, 28 or 42 watts. The ballast uses instant start and offers no dimming capability. Fixtures requiring dimming or a different bulb type are not compatible.

Thermal Behaviour

Rated for a minimum starting temperature of -22 degrees F, the unit operates reliably in cold outdoor environments such as parking lots. As an electronic ballast, it runs cooler and quieter than magnetic alternatives while drawing only the power needed for the connected lamp.

Questions about this item

How does the 120V AC input translate when the ballast is installed in a fixture?

The unit accepts standard 120V AC mains supply and drives a single compatible lamp at its rated wattage.

What does the instant-start specification mean for daily operation?

Instant start ignites the lamp without pre-heating the cathodes, giving immediate light but slightly reducing lamp life compared with programmed-start models.

Which lamp types and wattages can this ballast physically accommodate?

It supports one T5 or T6 fluorescent lamp from 4 W up to 42 W, covering the 13 W, 14 W, 21 W, 28 W and 42 W ratings listed.
