Fluorescent Sign Ballasts

Although fluorescent sign ballasts perform the same electrical tasks that their interior counterparts do, these devices are made for harsher environments and more taxing usage conditions. It's critical to select an appropriate ballast that is specifically engineered to meet the unique demands of industrial and commercial signage.

Major Functional Differences

Where other ballasts are largely protected from the elements, the versions used to power the bulbs contained in signs are often at risk of direct moisture contact or debris exposure. Because these devices carry the potentially hazardous high voltages and currents necessary to drive fluorescent lamps, they're generally designed to incorporate integrated housings and secure connecting terminals.

Another unique feature found in many sign ballasts is their ability to start up rapidly or instantly in a wider range of weather and temperature conditions. This is critical for firms that don't want to wait for their signs to light up after throwing the switch. Some ballasts also incorporate smart-control technology for easier remote operation.

Choosing a Fluorescent Sign Ballast

Like other ballasts, fluorescent sign devices are made to accommodate specific numbers of lamps. It's also important to consider that different signage arrangements have unique internal lamp lengths, so be sure to choose a ballast that can support the total bulb footage that your sign contains. Sign manufacturers should also be careful to select a ballast that bears UL or EISA approval in order to produce signage that meets applicable regulations or achieves specific energy-efficiency targets.
