How many lights fit on a transformer?
Wondering how many lights you can fit on your in-lite transformer? It involves a little bit of math (don’t panic!) and it’s a lot simpler than you think.
Follow these few simple steps to manually calculate how many light fixtures fit on your transformer. Or, shoot us an email at email@example.com or message us on the website and we can send you our watt calculator that will do all the math for you (we told you we’ve always got your back).

First, you have to determine how many watts your transformer can hold. With low-voltage lighting, we recommend only using 90% of the available watts. This will ensure you don’t run into any issues by overloading your transformer and tripping the system. The number of watts a transformer can hold will be listed on the website or on the box of the product.
(Note: W = Watts)
For this example, we are using the in-lite 108 W transformer. Of the 108 W, we only want to use 90% so we have about 97 W to work with.
Next, determine how many watts each fixture consumes.
This information can be found on the back of product boxes, on our website (scroll down on the product page until you see ‘More Information’), in our brochures, or in our spec sheets. If you still can’t find what you’re looking for, shoot us a message and we can help you out. But trust us, you should be able to find the watts your fixture consumes (we put it everywhere to make it easier for you!).
When you find the wattage for your fixture, write it on a piece of paper. Do this for every different fixture in your project.
Once you’ve done that, write down how many of each fixture you need. Then multiply the watts by the number of fixtures you will be using in your project. Do this for each fixture type individually. This is the amount of wattage that each type of fixture will consume.
Finally, add all the wattage totals together.
If your total is less than 90% of your transformer capacity, all of your lights fit one transformer!
For this example, our transformer holds 97 W (90% of 108 W) and our fixtures only consume 44.5 W. So, we only need one transformer and we have room to add more lights at a later date.
It may seem tricky at first, but don’t worry, you’ll get the hang of it.
