Have you maxed out the power of your LED controller?
This Inline RGB LED Amplifier will take any PWM (pulse width modulation) signal, and amplify it, so you can power another 12 amps of LED strips.
If you're just powering 1 LED strip, you don't need this.
But if you're powering 10 from the same controller, you might need this depending on how much current the LEDs pull.
Requires 12V DC Input. Common positive. Works with any common positive LED controller.
Here's a diagram of how to hook it up:

We've conducted a number of experiments with LED strips. Here's what we found:
Finding 1: We found it's quite difficult to get a stable color from RGB LED strips when connecting multiple long sections together.
It's from the issue of "voltage drop", and the long path the current must travel over a thin circuit board.
Finding 2: We found that the consistency of LED colors becomes poor after we connect one more sets of 16 foot RGB LED strip lights. This is related to the "voltage drop' issue.

After using LED Amplifier:
After this experiment, we recommend you buy these inline amplifiers.
For the best color consistency and performance, we suggest you use an amplifier on every 16 foot LED strip light.

Customer questions & answers
Your answer seems contradictory and I think you may have missed the point of my last question. I am wanting to know if putting a switch on the red power wire to the amplifier would allow me to turn the strips after the amplifier on and off. OR if the power is off to the amplifier, does the signal still pass through and thus potentially have color problems in longer strips instead of the latter strips being off completely. - by Jason
Thank you, I did not understand about the switch in your last question. Adding a switch to the amplifier will only effect the power from the amilier not shutting the leds off. They will still receive power from the main power source.
If I have this in-line amplifier installed, what happens if I do not supply power to the red wire on the amplifier? Ideally I would like to have a switch on the power supply to the amplifier to be able to select which strips are turned on. - by Jason
That would defeat the purpose of the amplifier, not using the red wire no power would be given to the strip. Maybe install a switch to control the amplifier.
how many amplifiers for 16 ft strips can be connected? - by GARY (UNITED KINGDOM)
Don't quite understand your question, if you are connecting 2 or more 16 ft strips you should use one amplifier. If that didn't answer your question let me know.
