UL certification of the fixture, which is generally granted based on the assumption that a ballast is or will be part of the system, is lost when the ballast is. UL Type C involves electrical modification to the existing fixture, but the low-voltage outputs of the external LED driver are connected to the sockets instead of line voltage as with UL Type B.
How to decide which type of LED T8 retrofit tube is right for you..
Ul type b led tubes. PARMIDA 20-Pack 4FT LED T8 Hybrid Type A+B Light Tube, 18W, Plug & Play or Ballast Bypass, Single-Ended OR Double-Ended Connection, 5000K, 2200lm, Frosted Cover, T8 T10 T12, Shatterproof, UL & DLC 4.5 out of 5 stars 503 UL Type B is more efficient than UL Type A, with no ballast-driven power losses. UL Type B LED tubes can further be categorized as single-ended or double ended.
Start searching the wide variety of wholesale LED tube lights we have available in our inventory. For Dual Mode (UL Type A and B) products, these fields should record the AC voltage input range for which the product is designed to operate as a Type B replacement lamp. By using a ballast bypass design, there’s one less possible point of failure, making the fixture more reliable.
UL Types of LED Tubes: Philips ballast bypass (UL Type B) T8 LED lamps use a double-ended design which significantly simplifies installation, saving time and costs. The ballast bypass (UL Type B) solution has everything needed built into the lamp, energy savings, long life, surge suppression and industry leading safety features.
It details the safety. ( See product specification sheets for more information) Less energy used through elimination of ballast draw An extra couple of watts is consumed when you pair an LED lamp with a ballast.

This standard differentiates among three different types of LED tube lamps (Types A, B and C). Revolution Lighting’s T8 Single-End-Power (SEP) LED PC Tubes can be installed into any new or existing fixture designed for similar fluorescent lamps and can reduce lighting energy use by as much as 60%. The Lowdown on TLEDs.
LED Linear T8 Hybrid – UL Type A+ B. If you’re considering upgrading your fluorescent tubes to LED tubes, or are simply thinking of replacing other LED tubes, you’ll first need to understand installation and operation of the three different LED tube options available: ABCs of MaxLite LED Tubes.
You can simply replace your existing lamps with new Type A LED lamps. However, most UL Type B LED tubes lack dimming and control capabilities. Measured luminaire efficacy of DLC-listed 4-foot LED linear replacement lamps by UL type 4/20/16 Minimum Mean Maximum TLEDs Efficacy Min required luminaire efficacy is 85 lm/W .
LED T8 Tubes with Internal Driver (bypass Ballast) – Type B. Our External Drive tubes are designed to be powered only by Keystone drivers. Now we have designed a T8 LED retrofit lamp that is the perfect solution making the move from fluorescent to energy saving LEDs simple.
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. The LED driver, however, is integrated into the LED tube itself. The primary standard for LED luminaire retrofit kits, UL 1598C, was published in January 2014.
This results in added energy savings as LED T8 tubes that run on a ballast are less efficient. These tubes also offer a 240° beam angle for excellent coverage of any area you’re looking to light. The wall plug efficiency with direct line voltage tubes will be higher than with plug-and-play tubes.
These innovative LED tubes eliminate the need for an external driver or ballast. Special Considerations for Linear Replacement Type-C Lamp Systems with Non-Identical Lamps NORTHBROOK, Ill., July 5, 2017— The following is a notification from UL that the Direct Replacement LED Tube lamp
This product can replace either T8 or T12 lamps in fixtures containing shunted or non-shunted G13 (medium bi-pin) lamp holders. GE Double Ended Ballast Bypass LED Tube (UL Type B) Also available in Single Ended Ballast Bypass Configurations. TYPE B LED (Ballast Bypass/Direct Wire) The Type B requires rewiring of the fixture to supply line voltage directly to the lamp holders or sockets.
No rewiring is required, no electrician is required. WHAT ARE TYPE “A,” TYPE “B,” TYPE “C” TUBES. Type B T8 LED Retrofit Lengths;
Ballast-bypass T8 LED tube pros and cons (UL type B) Ballast-bypass LED tube (Type B) pros: Type A, Type B, Type C, And Type A+B. Type-A LED tubes, Type-B LED tubes, and Type-C LED tubes.
Keystone makes upgrading fluorescent lights to LED easy with our UL Type B DirectDrive tubes. Type B LED Tubes have an internal LED driver which allows them to bypass the existing fluorescent ballast in a fixture and wire directly to line voltage. They cannot be used with the fluorescent ballast, and must be connected directly to mains electricity.
Not only do our Type B Ballast Bypass direct wire 4ft LED tubes remove the need to install entirely new fixtures during your LED conversion, their double-ended power makes it so that even the tube installation will be as painless as possible.
