The Difference Between Built-in IC and the External IC Strips?

Sometimes, you might hear from your suppliers that which IC of LED chips do you need? The meaning of built-in and external is simple, but do you know the difference?

1. The external IC strip is controlled by a single IC at the same time. The stability is relatively weak. If there is a LED chip failed, all the LEDs can no longer be used. While the built-in IC strip is one IC that controls one LED chip, adopting one-to-one mode, even if one IC has a problem, it will only affect one LED chip, and other LED chips will not affect the use. That means the built-in IC strip is more stable than the external IC strip.

2. The price is totally different as they will need different production technology.

3. The external IC has solder onto the PCB, which built-in IC has been inside the LED. So their appearance is different.

4. Built-in IC strip can decrease the damaging of the resistors than the external IC strip.

    I just purchased 4 boxes of the RGBIC DreamColor LED Strip Lights, 32.8 ft. per box, (2) 16.4 ft. spools per box.
    My question is how many strip lights can I connect to one power supply. I know that each power supply has two (2) connectors to connect each of the spools. My goal is to connect approximately 100 ft. of RGBIC LED Strip Lights and to be able to use one controller and activate via Google or Alexa Voice Command.

    I see that the provided Power Supply is rated at +12 Volts DC at 3 amps. Could I install a +12 volt aftermarket external power supply rated at higher amperage in order to use only one power supply and one controller for all 4 boxes (8 spools) of LED Strip Lights.
    I know of consequences and I assume all liability for any damage to the LED Strip Lights if possible.

    One other question I have is there a 100 ft. RGBIC LED weatherproof strip light available. I’ve searched but could not locate any.

    Please advise and provide any schematic diagrams if possible to use one power supply.

    Thank you

      Normally, one power supply can only connect two lights strips, If you want to use a power source and remote control to control 100FT, it currently hardly gets successful.
