Ballast and Other

Electronic ballasts are essential components for controlling voltage and current in fluorescent tube lighting installations across residential, commercial, and industrial projects. iSupply Electrical stocks a comprehensive range of electronic ballasts compatible with both T5 and T8 fluorescent tubes, covering wattage specifications from 14W to 58W to meet diverse project requirements.​

Our ballast range includes single-lamp (1x) and dual-lamp (2x) configurations designed for 220-240V AC applications, ensuring compatibility with Australian electrical systems and compliance with AS/NZS 4783 energy efficiency standards. Electronic ballasts offer superior energy efficiency compared to traditional ferromagnetic alternatives, reducing heat loss and extending lamp lifespan—critical factors for maintenance-conscious electrical contractors managing multiple installations.​

Whether you’re fitting out commercial office spaces, industrial facilities, or residential projects requiring T5 or T8 fluorescent lighting solutions, our ballast selection provides the technical specifications and wholesale pricing that licensed electricians and electrical contractors rely on for project profitability. For complete lighting system solutions, explore our full Lighting category featuring tubes, battens, and fixtures to complement your ballast installations.​

All ballasts are available for same-day pickup from our Fairfield East location or fast delivery Australia-wide, keeping your projects on schedule without delays.​

Frequently Asked Questions (FAQs)

What’s the difference between T5 and T8 ballasts?

T5 and T8 ballasts are designed for different tube diameters—T5 tubes are 16mm diameter while T8 tubes are 26mm diameter. Each requires a ballast specifically matched to its tube type and wattage rating to ensure proper operation and compliance with Australian electrical standards. Our range includes dedicated ballasts for both T5 configurations (14W-35W) and T8 configurations (18W-58W) to cover all standard fluorescent installations.​

Are these ballasts compliant with Australian electrical standards?

Yes, electronic ballasts must meet AS/NZS 4783 minimum energy performance standards (MEPS) for fluorescent lamp ballasts in Australia. These standards require ballasts to achieve minimum Energy Efficiency Index (EEI) ratings and comply with IEC60929 performance requirements for electronic ballasts. All products in our ballast range are designed for 220-240V AC operation, standard across Australian electrical installations.​

What does the wattage rating mean on electronic ballasts?

The wattage rating (e.g., 1x18W, 2x36W) indicates how many fluorescent tubes the ballast can power and at what wattage. A “1x36W” ballast powers one 36-watt tube, while a “2x36W” ballast powers two 36-watt tubes simultaneously. Matching the ballast wattage precisely to your tube specifications ensures optimal performance, energy efficiency, and compliance with manufacturer warranties.​

Can I use electronic ballasts for LED tube retrofits?

Some LED tubes are designed to work with existing electronic ballasts (plug-and-play compatibility), while others require ballast bypass (direct wire to 240V). When retrofitting fluorescent installations to LED, verify LED tube compatibility with electronic ballasts before installation. Direct-wire LED tubes eliminate future ballast maintenance but require rewiring by a licensed electrician.​

What’s the advantage of electronic ballasts over magnetic ballasts?

Electronic ballasts offer significantly higher energy efficiency than traditional ferromagnetic (magnetic) ballasts, reducing the 15-20% energy loss typically associated with older ballast technology. They operate fluorescent tubes with less heat generation, eliminate flicker, reduce lamp failure rates, and extend overall system lifespan—making them the preferred choice for commercial and industrial installations where maintenance costs and energy consumption directly impact project profitability.​
