3 Methods of Power Injection for LED Lights

Welcome to one of the lessons from our full course on DIY Trim Lights. In this video, we’ll dive into the crucial topic of power injection for your LED trim lights by demonstrating 3 different ways to inject power into your LED runs. Understanding power injection is key to maintaining brightness and performance in longer runs of LED lights. There are multiple ways to do LED power injection, this will hopefully give you some direction on how to do it.

What You'll Learn:

What is Power Injection? Understand the concept and importance of power injection in LED lighting systems.

Why You Need Power Injection: Learn how voltage drop affects your LED lights and how power injection solves common issues.

Step-by-Step Guide: Follow our detailed instructions on how to implement power injection in your LED trim light setup.

Only 46 subs? Well I will make that 47. Seriously, I have been trying to understand power injection and the options avail for a few months now. I have a basic grasp of everything, but could not figure out for the life of me the solution shown in method 3. There are some amazing resources on YouTube, but their explanations never "clicked" with me (I will blame it on having a toddler and the lack of sleep that comes with it). NOW I see the answer to something that has hindered me in installing permanent outdoor lights AND allows me to fix some issues I have with previous builds. Cannot tell you how grateful I am for taking the random shot again today and searching "power injection led strips for long run of lights" to find your vid. Again, thank you!

Great video! Subbed. Please can you advise what fuse block you used and the setup? I haven't seen a single tutorial which includes the fuse Thanks

[nateF]

Awesome video production, and great tutorial. Thank you!

Your comparison fell apart as soon as you used two different types of LED strips. Really?

[ColbyHiggs]

Great video. Just what I needed. Thank you so much!

Hi dear. Which board ( controller ) you used on this video?

[RahulSingh-flbf]

Great helpful video, If i do method two, what are some safety precautions I should take to avoid getting shocked/starting a fire in my house?

Isnt it enough to inject red and run all grounds of the strips or is seperate ground also important?

[johnnagy]

I did this. And it is like everytime I hook up the injection line. It shorts out. I've checked 20 times. And my polarities are correct. I dont get it

Thanks for the video! I'm curious about what gauge wire you are using for the shunts. Looks like 20awg? I see you are using a much beefier wiring directory from the power supply to the octo board - 16 awg?

Cool video! If you have a long string of pixels (per example 800 pixels), could you inject at more than one point with only one wire or you have to use a new wire for every power injections at about 200 pixels each?

Fuse on Negative? Why? Only + gets fused.

[ReinkeDK]

Why didnt you inject in that start, the middle and in the end?

The way you connect the wires, is not omething I would do with the currents we are using. Get some decent connectors. I know in USA it's allowed to do it that way, but in Europe it's illegal due to fire hazards.

Poor explanation, next try using same type strips, to better example.
