This is a Unipro? 3 Circuit LED track live end or Feed connector as it’s sometimes known. It’s the part you need to apply power to the track. They can either be “earthing left” or “earthing right”. If you are just having a straight line of LED lighting track, it doesn’t really matter whether you chose a left or right LED track light power connector. It only becomes important when you turn corners, as you need to keep the track circuits the same. Speak to one of our team if you’re not sure which you require. Make sure you choose the correct finish to match your selected LED track colour, either black or white so your power connector co-ordinates. Don’t forget you will also need an end cap to finish the track and make it safe. If you need some help in selecting what part you need for your Unipro LED suspended track lighting, contact us or use our Live Chat in the bottom right corner. Don’t forget you also need an end cap to finish the track and make it safe. Have a read of our Track lighting guide.
