What is a Ballast?
A ballast is a device that sits between your power source and your fluorescent light fixture. Its job is to protect the fluorescent bulbs by controlling the flow of electrical current into the fixture. Since fluorescent bulbs cannot regulate current on their own, without a ballast, the bulbs can draw too much power and burn out. In addition to significantly shortening the lifespan of the bulb, this can create a safety hazard.
- Do LED Lights Need Ballasts? An LED light does not require a ballast because it uses a component called a “driver” to regulate the power going into the bulb.
- Do I Have to Remove Ballasts to Use LED Bulbs? This depends on the bulbs. Some LED bulbs may require you to remove the ballasts. However, a high-quality plug and play LED tube - like Warehouse Lighting’s Triple-Fit 4’ T8 LED – can be used in direct wire fixtures as well as traditional fluorescent fixtures with ballasts. In other words, thanks to its flexibility, you use a plug and play LED without ballasts or with.
What are Plug and Play LED Tubes?
Plug and play LED tubes are shaped just like fluorescent bulbs and connect to the fixture the same way. Since plug and play LEDs are compatible with ballasts, you can simply remove a fluorescent bulb and replace it with an LED. Since no additional modification or wiring is required, it’s as easy as replacing incandescent bulbs with LED bulbs in your home.
- What is a Ballast Bypass? A ballast bypass is when you remove a ballast from the electrical circuit that goes to your light fixture. Since the ballast sits between your power source and the light fixture, this means either removing the ballast completely or simply disconnecting the ballast and wiring the light fixture straight into the power source. You can learn how to bypass a ballast here.
Pros and Cons of Keeping the Ballasts (Plug and Play)
PROS
- It’s the easiest solution (no wiring or modification is required).
- You still have the option to use fluorescent bulbs.
- The ballasts, while not technically necessary, may provide an additional level of protection to the light fixtures.
CONS
- The ballasts will eventually wear out and need removal or replacement.
- Some lighting experts believe LEDs provide better light and are more efficient when the ballasts are removed.
Pros and Cons of Removing the Ballasts (Ballast Bypass)
PROS
- There are fewer components to wear out and require replacement.
- Some lighting experts believe LEDs provide better light and are more efficient when the ballasts are removed.
CONS
- Rewiring of the fixtures is required.
- You can no longer use fluorescent bulbs in the fixtures.
- You have to be careful fluorescent bulbs are not used, as this can pose a safety issue.
- The ballasts, while not technically necessary, may provide an additional level of protection to the light fixtures.
When to Choose Plug and Play vs. Ballast Bypass
Each LED upgrade method has specific scenarios where it makes the most sense. Below is a guide to help businesses determine the best solution based on their needs.
When Plug and Play is the Best Option
- Quick fix: No need for rewiring or electrical work.
- Temporary lighting solutions: If you plan to upgrade fixtures later, this is an easy way to transition to LED.
- Ballast-required industries: Some industries require ballasts for regulatory reasons or compatibility with existing controls.
- Fluorescent backup flexibility: If you may still use fluorescent bulbs in the future, plug and play LEDs allow for dual compatibility.
When Ballast Bypass is the Best Option
- Maximizing energy efficiency: Eliminates ballast energy consumption, reducing long-term electricity costs.
- Long-term reliability: Fewer components mean fewer failure points, extending lifespan.
- Older facilities: If your ballasts are already failing or outdated, it's cheaper to bypass them now.
- Smart lighting integration: Ballast-free LED tubes can be used with dimmers, sensors, and smart control systems for better efficiency.
Plug and Play vs. Ballast Bypass Comparison
Feature |
Plug and Play LED |
Ballast Bypass LED |
Installation |
Simple installation, no rewiring needed. |
Requires rewiring and ballast removal |
Cost |
Lower upfront cost, but higher long-term cost due to ballast replacements. |
Higher upfront cost due to labor, but lower long-term cost with no ballast replacements. |
Lifespan |
Dependent on ballast lifespan; LEDs last longer, but ballasts may fail. |
Longer lifespan—fewer failure points since ballasts are eliminated. |
Maintenance |
Requires periodic ballast maintenance and potential replacement. |
Minimal maintenance—no ballasts to replace. |
Energy Efficiency |
Slightly less efficient due to power consumption from ballast. |
More efficient—no energy lost to ballast, direct power to LEDs. |
Uses |
Best for quick upgrades, temporary lighting, or locations where fluorescent compatibility is needed. |
Best for long-term savings, older buildings, or facilities transitioning fully to LED. |
