As more and more people switch to LED lighting, track lighting systems have become increasingly popular for their flexibility and efficiency. These systems can be used to highlight artwork, create mood lighting, or simply light up a room with maximum efficiency. However, choosing the right track lighting system for your space requires some knowledge of the different types available and their components.

In this how-to guide, we’ll walk you through identifying your track lighting system and its components so that you can make an informed decision about which one is right for your needs.

Understanding Track Lighting Systems

Track lighting systems consist of three main components: tracks, fixtures, and connectors.


Tracks are the foundation of track lighting systems. They are long strips made of metal or plastic that are mounted on ceilings or walls. The tracks hold the fixtures in place and provide power to them. There are two main types of tracks:

  • H-Type Track: H-type tracks are named because they resemble the letter “H” when viewed from above. They have two conductive rails that carry power from the transformer to the fixtures.
  • J-Type Track: J-type tracks are also called Juno tracks after their inventor. They feature a single rail with a positive conductor on one side and a negative conductor on the other.


Fixtures come in various shapes and sizes but all serve the same purpose – providing light where it’s needed. There are three types of fixtures:

  • Line Voltage Fixture: Line voltage fixtures connect directly to 120-volt electrical wiring without requiring a transformer.
  • Low Voltage Fixture: Low voltage fixtures use transformers to convert 120 volts AC into 12 volts DC which is safer for handling than high voltage.
  • LED Fixture: With advances in technology there is now LED based fixture option available as well which consume very minimal energy while giving sufficient amount light output


Connectors join tracks together or connect tracks to the power source. They come in various shapes and sizes to accommodate different track types and installation needs.

  • Straight Connector: This connector joins two tracks end-to-end.
  • L Connector: An L connector allows for a turn of 90 degrees and is ideal when creating an “L” shape of lighting across a room.
  • T Connector: A T connector allows you to branch off from the main track in either direction, giving more flexibility in directing light around corners or obstacles.

Identifying Your System

Now that you understand the basic components of track lighting systems, it’s time to identify which system you have or need.

Step 1 – Determine Track Type

The first step is determining whether your existing fixture uses an H-type or J-type track. The easiest way to tell is by looking at it.

If you see two parallel conductive strips running down the track, then it’s most likely an H-type. If instead, there is only one conductor with a negative side on one edge and positive on the opposite, then it’s a J-Type.

Step 2 – Check Compatibility

After identifying your current track type (or choosing which one fits your needs), double-check that any fixtures and connectors are compatible with that specific type of rail. It’s always best practice verifying compatibility before making any new purchases, as mixing incompatible parts can lead to performance issues like flickering lights or even permanent damage.

Step 3 – Choose Fixtures And Connectors That Fit Your Needs:

Once you’ve confirmed compatibility between all parts involved in setting up your lighting system, Choosing functional fixtures along with compatible connectors comes into picture as per usage requirements will ensure maximum convenience without compromising quality .In general LED based fixture are preferred over their conventional counterparts as they offer better color rendering , last longer than other types while consuming less energy at same time .


By following this guide and identifying your track lighting system components, you will be able to choose the right fixtures and connectors that are compatible with your existing setup or future installation projects. Remember, understanding the different types of tracks, fixtures, and connectors can make a big difference in the efficiency and aesthetic of your track lighting system.


Q: How do I identify the type of track lighting system I have?
A: There are three main types of track lighting systems – H, J and L. To determine what type of track you have, look at the end of the track where it connects to the power source or mounting hardware. If your track has two metal contacts that resemble a “T” shape, then you have an H system. If it has a single notch-like contact in the middle, then you have a J system. Lastly, if there is a longer rectangular notch followed by a shorter one on either side of it, then you likely have an L system.

Q: Can I mix different types of fixtures on my track lighting system?
A: This depends on whether your fixtures are compatible with your specific type of track lighting system. Most manufacturers design their fixtures to fit only one type of system due to differences in electrical connections and mounting methods between H, J and L tracks. However, some manufacturers offer adapters that allow users to switch between different systems without having to change their fixture.

Q: How can I adjust or reposition my track lights after installation?
A: Most modern track lighting systems come with adjustable heads that can be easily rotated or tilted to aim light in different directions as needed once they are installed on the track itself.It’s important to turn off power before adjusting any partoftheinstallation process before startingto avoid accidents during operation.Also ensurethatyourfixtureis compatiblewith themodelnumberwhenchangingits positiononyourtracklightingsystem
