Determine the Power Supply
The first step in setting up whole room RGB lights is determining the maximum power consumption of your LED strip. This information will help you select the appropriate power supply. The current rating of the power supply depends on the size of the LED strip and the density of the LEDs.
- Measure the length: Consider how long you want your LED strips to be. This measurement will impact the overall power requirements.
- Choose the density: If you desire high brightness, opt for a high-density LED strip.

Using a Single LED Strip
If you are using a single set of LED strip, check the current/voltage rating mentioned on the box. You can then choose a power supply that matches the voltage rating of the LED strip (most LED strips require 12V), while ensuring that the current rating of the power supply is greater than the maximum current required by the LED strip.
Joining Different Sets of LED Strips
In some cases, you may need to join different sets of LED strips together. In this situation, you can calculate the maximum current rating as follows:
- An RGB LED consists of three different color LEDs (Red, Green & Blue) in a single package, with each color consuming a maximum of 20mA.
- A 12V LED strip consists of various segments connected in parallel, with each segment consisting of 3 LEDs connected in series.
- Since the LEDs are connected in series, all 3 LEDs in each segment would consume the same current, which is 60mA in this case.
- Therefore, the maximum current consumed by each RGB LED in a strip is 20mA.
- Using the formula
I(max) = 20*N*L
, where N is the number of LEDs per meter and L is the length of the LED strip in meters, you can calculate the maximum current rating of the strip.

For example, if an LED strip has 60 LEDs/m (N = 60) and a length of 5 meters (L = 5), the maximum current rating would be:
I(max) = 20 * 60 * 5 = 6000mA = 6 Amperes
In my case, I used 30 LEDs/m type and 4 LED strips that are 2 meters each. So, N = 30 and L = 8. Therefore, the maximum current rating is:
I(max) = 20 * 30 * 8 = 4800mA = 4.8 Amperes
Ideally, the power supply's current rating should be 20% higher than the calculated maximum current rating of the LED strip. However, any value greater than the calculated value will work. Just keep in mind that choosing a power supply with a significantly higher current rating may impact its durability in the long run.
Please note that these calculations specifically apply to non-addressable RGB LED strips rated at 12 Volts, which are the most common type. Based on these calculations, I chose a 12V 5A adapter for my setup.

Frequently Asked Questions
-
What if I want to use addressable RGB LED strips?
- Addressable RGB LED strips have different power requirements and need a specialized controller. It's best to consult the manufacturer's specifications for determining the power supply and installation procedure.
-
Can I use a power supply with a lower current rating than the calculated maximum current?
- It is not recommended to use a power supply with a lower current rating as it may lead to insufficient power supply, resulting in poor performance or even damage to the LED strips.
-
Can I connect multiple sets of LED strips to a single power supply?
- Yes, you can connect multiple sets of LED strips to a single power supply, as long as the power supply's current rating is sufficient to handle the combined maximum current requirements of all the LED strips.
Now that you know how to set up whole room RGB lights, it's time to bring your space to life with an explosion of colors and ambiance. Get ready to immerse yourself in a visual extravaganza that will leave everyone in awe. Let the lighting adventure begin!.
