The ABCs of LED Tubes

• Differences between UL Type A, B, C & Hybrid Tubes

• Operations and maintenance considerations

• Installation cost/benefit comparisons

As a rapidly growing lighting technology, LED linear tube options are raising questions throughout the
industry—it’s important to know the options and which one will work best for you.

When considering LED Tube refits, it is important to understand the financial aspects as well as the
installation, operations, and maintenance implications with three different options, which are UL Type A,
UL Type B, and UL Type C.

LED Tube with Integrated Driver - Compatible and Operated on Existing Ballast

Description Type A tube is designed with an internal driver that allows the tube to operate directly from the existing linear fluorescent ballast. Most of these products are designed to work with T12, T8 and T5 ballasts.

Advantages UL Type A offers the simplest installation process— retrofitting involves a simple swap of the existing LFL with a UL Type A LED tube. Unlike the other options, no electrical or structural modification of the existing LFL fixture is required.

Disadvantages However, with these benefits come some limitations. The lifetime of a UL Type A solution is dependent not only on the design life of the LED tube, but on the linear fluorescent ballast life, which could result in additional maintenance and costs within the lifetime of the product. Ballast compatibility will vary by manufacturer and must be checked prior to install.

Additionally, a UL Type A tube sacrifices efficiency due to the additional power loss from the existing ballast and is limited in dimming and controllability.

Ballast Bypass LED Tube - Wired to Mains

Description Like the UL Type A, this UL Type B tube operates with an internal driver. However, UL Type B’s internal driver is instead powered directly from the main voltage supplied to the existing LFL fixture, requiring several important and unique considerations. GE’s Type B system requires a in-line fuse. GE offers in-line fuse & socket kit, for ease of installation.

Advantages UL Type B offers the simplest total system— retrofitting involves wiring directly to main voltage, bypassing the ballast which removes any compatibility issues, as well as eliminating maintenance costs associated with ballast replacements.

Disadvantages Installation of a UL Type B involves electrical modification to the existing fixture in order to connect the tube to the power supply. The existing LFL and its corresponding ballast must be removed from the fixture. Sockets should be replaced. (GE requires replacing with unshunted sockets.)

UL Type B is more efficient than UL Type A, with no power loss as a result of removing the existing LFL ballast, but similarly lacks control capabilities.

It is important to note that the fixture’s incoming power wires are connected directly to the sockets, meaning installers are potentially exposed to the main’s voltage during installation. For replacement safety reasons, strict adherence to installation instructions is critical when rewiring existing fixtures and utilizing UL Type B tubes. Safe installation can be completed, but total installation time and cost will increase because of additional precautions required.

Top Misconceptions for Type B Solutions

“But once I convert to Type B, I will never have to replace a ballast again.” True, the external ballast will have been removed. However, the electrical conversion from mains voltage to the LEDs still needs to be done. With Type B, this is done entirely within the Tube itself. In order to accomplish this, Type B Tubes require much more complex internal circuitry than Type A and Type C. As such, there are more components to potentially fail. This may result in higher incidence of lamp replacement.

“But isn’t all of that circuitry in the ballast or driver?” Essentially, yes. But an external ballast or driver allows for a less challenging thermal environment for the electronics, due to the availability of space, remote placement of the device, and ability to use potting as required. Inside a lamp, like a Type B tube, the electronics are confined to a small space, near additional sources of heat (the LEDs), often within an additional enclosed reflective fixture. Also, Type B applications are more susceptible to damage or failure from transient voltages/power surges, whereas an external driver or ballast has a robust design that offers more protection. These factors need to be considered in regard to overall reliability of a very long-life lamp.


LED Tube with Remote Driver

Description A UL Type C tube, offered among GE’s Refit Solutions as the LED Tube with remote driver, operates with a remote driver that powers the LED linear tube, rather than an integrated driver. Like UL Type B, UL Type C involves electrical modification to the existing fixture, but the low-voltage outputs of the driver are connected to the sockets instead of line voltage.

Advantages Installation for UL Type C tubes involves removing existing tubes and ballasts, and it may involve replacement of existing sockets, if damaged. The fixture input wires must be connected to the LED driver, and the driver’s low-voltage output wires must then be connected to the sockets before installing the new LED linear tubes. Once installed, this driver can power several LED tubes throughout the fixture. The UL Type C offers excellent system efficacy, best system compatibility and greatest overall performance. It can be integrated with robust dimming and control functionality, helping to offset moderate labor and installation costs with heightened efficiency well into the future.

LED Hybrid Tube works with or without ballast

Some manufacturers have recognized the opportunity to provide LED tube lights that work with Electronic Ballasts (T8) or have the ability to bypass ballasts when the ballast no longer works. This has given rise to a new category, the hybrid tube light. Hybrid tubes work with T8 electronic ballasts but can also be wired directly like a ballast bypass tube light to T12 fixtures or should the T8 ballast fail or if a facility has a mixed environment with T8 and T12 that require both wiring types.
