How to use LED Lighting Terminal Block Extenders
Published by John W. Wagonis in Lighting · 7 February 2021
I need to install a dozen LED under cabinet lights in my kitchen. Can I do it from one low voltage LED power driver?
Excellent question. Class is in session. It will be easier to explain by focusing on just one LED light model, and that will be the Loox 3038 LED light. Then everything explained will apply equally to the 12 volt lights as well as the 24 volt.
In this article we are going to cover:
- the various LED power drivers
- the 6-port terminal block extender
- the 4-port cable extender
- the various individual extension wires

The below components are all shown on our Loox LED Power Drivers and Dimmers page. So we will not keep adding the same link reference over and over.

The terminal block extender with a lot of reach

It has the one male connection on it which connects into the driver. Then 4 female ports spaced apart along the rest of its extension to allow you to connect light after light still stretching farther out. If you have need of more lights, say two lines of them, possibly 3 lights on the front side of the island and 3 in parallel on the other side, you can add a 6-port extender into one of those ports about halfway down and continue to add lights. Just as long as you stay under the maximum wattage for the driver you are using. Thus terminal block extenders can also connect into themselves. You don't want to get too crazy. If you are mounting 20 or 30 lights in your kitchen, you might want to break them up into zones. Or you might have to break them up in to zones. With all the components and lights available individually, you can create whatever set up you need.
Extension wires

Extension wires can also be used from the terminal block extenders. Or even leading up to an extender. An example of that, we hear about a lot of older halogen light systems being hooked up where the transformer is in the basement. Yep, very common to find the transformers in the attic, the basement, or 5 cabinets over. Thus more wire is needed to reach the lights. So when you mount the LED power driver farther away, you can use an extension lead out of it, connect a 6-port terminal block to that extender, and it would equate to the same thing as putting the six ports that are part of the driver somewhere else. Where they can reach the lights. You can be quite crafty with your hookup.
All of the above is showing the green connections for the 24v light systems. Everything above, including the switching controls out of the side port of the drivers, applies to all the 12v light systems too. The 12v have orange connections. Done on purpose so you do not mix up lights on drivers. Some kitchens could have a mix of 12v and 24v. Or just mixed throughout the house. Under cabinet lights are used in bathroom cornices and cabinets. They are used in hutches, in bars, in desks, even in bedroom furniture. Having the ability to use the number of lights where you want, and the flexibility of various size power drivers, switching controls, and stretching things out farther away, count on the Hafele Loox LED Lighting Systems to fulfill your lighting needs.
The future
Hafele has just launched Loox5. All of the above components are still available. But changes are happening. The drivers will be made without ports on them. You will connect a distributor to the driver which will give you the ports you need. Multiple distributors can be connected to each other per driver. Each could have separate switching control if you like. Extension wires and terminal block extenders can still be used. There will be convenient port convertors to connect the old to the new or the new to the old. So there will be some changes coming. We will have a little rewriting to do on our web pages. Lights will be the same with many more added. And Hafele is not going to leave anyone hanging. With the port convertors, which come in 6-packs, if you ever need to expand upon what you need in your home, or replace a component, you will be able to do so without having to rip everything out and start over. Like a lot of us have been doing with the older halogen lights which are aging. Since halogen is not being produced and the world is switching over to LED, it is important to have an LED manufacturer who takes measures to assure you that you can keep your lights on in the future. Hafele Loox is there for you.
Hafele Loox has a lot more goodies than what we presently show on our website. We do plan to add more web pages and start showing off more of what you can do in your home or office. Lots of display lights too.
