LanTingWei - UL CUL DLC 2FT Line Voltage AC Bi-Pin G13 Base Non-Screen Flickering Non-Dimmable Ballast By-Pass T8 LED Tube Light in Aluminum+PC Housing

* UL CUL DLC Approved

* 2 Feet (24'') Long LED Tube Lights made with aluminum housing + PC Lens.

* CRI80 130LM/W fit for different applications.

* PF>0.9

* Direct Drive LED tubes to eliminate the need for an external driver or ballast. For new construction installations, simply connect the line voltage directly to the sockets. For retrofit installations, bypass the existing ballast by cutting the wires and connecting the line voltage directly to the sockets. No ballast or driver is required.

* The Ballast Compatible Type Tube offers the simplest installation process—retrofitting involves a simple swap of the existing tube with the LED tube. Unlike the other options, no electrical or structural modification of the existing fixture is required.

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

Description
This UL 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 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. Also, compatibility with
various linear fluorescent ballasts on the market may vary, depending on different manufacturers
and models.
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

Type B
LED Tube with Integrated Driver - 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 fixture, requiring
several important and unique considerations. When using this tube to retrofit the old tubes,  electrical or structural modification of the existing tube fixture is required.
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 may need to be replaced, and a connection is required from the fixture input
wires directly to the sockets.
UL Type B is inherently more efficient than UL Type A, with no power loss from the removal of
the existing LFL ballast, but it is similarly limited in dimming and 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 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 high-voltage wiring.

Type A+B
LED Tube with Integrated Driver - Compatible with existing ballast or Wired to Mains

Description
The UL type A+B tube combines the features of Type A and Type B tube.
The tube driver allows the tube both to operate directly from the existing linear
fluorescent ballast and to be powered directly from the main voltage supplied to the existing fixture, which is friendly for both retrofit and new installation.
