Upgrade to T8/HO and T12/HO LED Retrofit Bulbs

Transform your commercial or industrial lighting with powerful, energy-efficient T12 to LED bulbs. Whether you're replacing T8/HO or T12/HO fluorescent tubes, these LED retrofit bulbs offer a reliable, cost-effective alternative that cuts down on energy usage and maintenance without sacrificing brightness.

What Are T12 to LED Bulbs?

T12 LED replacements are designed to retrofit high-output T12 fluorescent tubes commonly found in warehouses, factories, gymnasiums, and industrial buildings. These LED upgrades reduce electricity usage by up to 70% while providing long-lasting performance—often exceeding 50,000 hours of life.

T8/HO LED retrofit bulbs serve the same function for T8 high-output fluorescents and are available in lengths from 2 to 8 feet. T12/HO LED retrofit options are typically available from 4 to 8 feet, giving you flexibility for various fixture types.

Benefits of Switching from T12 to LED Bulbs

  • Significant Energy Savings: Reduce energy use by 50–70% over traditional fluorescent lighting
  • Longer Lifespan: LEDs last up to 5x longer, minimizing replacements and downtime
  • Better Light Quality: Instant-on brightness with no flicker or warm-up time
  • Environmentally Friendly: Mercury-free and emits no UV radiation
  • Durability: Built for tough environments with shock- and vibration-resistant design

T12 vs T8: What’s the Difference?

T12 fluorescent tubes are typically larger in diameter (1.5 inches) compared to T8 tubes (1 inch), and they're generally less efficient. LED replacements are available for both sizes, but T8 tubes tend to be more energy-efficient by design. If you’re unsure whether to choose a T12 or T8 retrofit LED, consider the socket compatibility and the intended brightness output.

Simple Retrofit Installation

Most T12 to LED bulbs can be installed in existing fixtures with minimal rewiring, depending on whether you're using a ballast-compatible, ballast-bypass, or hybrid LED tube. Be sure to check product specifications and consult with an electrician if needed.

Upgrade your workspace lighting today with high-output LED retrofits built to replace outdated T12 and T8 fluorescent tubes—delivering long-term performance, safety, and energy savings.

Frequently Asked Questions

Can I replace T12 fluorescent tubes with LED bulbs?

Yes! T12 LED replacement bulbs are designed specifically to retrofit traditional T12 fluorescent tubes. Choose from ballast-compatible, direct wire, or hybrid options depending on your fixture setup.

What’s the difference between T12 and T8 bulbs?

T12 bulbs are 1.5 inches in diameter and generally less efficient than T8 bulbs, which are only 1 inch thick. T8 LED replacements are typically more energy-efficient, but both T12 and T8 tubes can be upgraded to LED with the right retrofit option.

Do I need to remove the ballast when switching to LED tubes?

Some LED retrofit tubes are ballast-compatible and work with existing ballasts, while others require a ballast bypass. Always read the product specifications or consult with an electrician before installation.

Are T12 LED replacements available in 8-foot lengths?

Yes. Many T12 to LED bulbs are available in 4-foot and 8-foot lengths, making them ideal for high ceilings and large commercial spaces.

Are LED tubes safer than fluorescent tubes?

Absolutely. LED tubes are mercury-free, emit no harmful UV rays, and generate less heat—making them a safer and more environmentally friendly lighting option.
