If you look this web site there is......................
- No Ledcontroller needed, directy to 12V
Consumption
Red: 100mA @ 12V (~1.20W)
Green: 80mA @ 12V (~0.96W)
Blue: 87mA @ 12V (~1.04W)
Total:~260mA @ 12V (~3.12W)
And when you zoom picture whitch show the resistances you can see
that one strip-module is connected as 2 led´s and 1 resistor serial
times 3.
( 2 leds and 150 ohms & 2 leds and 180 ohms & 2 leds and 330 ohms )
................so you can connect these strips without external resistors
to the 12 V power supply.
1 strip all leds on draws 260mA
so 4 strip needs 1.04A
You need 12Vdc / 1.5Amin. power source.
I drow connection example for you.
(Warning : Check right polarity or you gonna destroy all leds !!!! )
You can protect power supply by adding 2A fuse right after output connection point.
