I'd like to control some outdoor lights (on, off, dim) with a Pi but I am not sure about the best way to do it. I would prefer to use a wired connection instead of wireless. I have seen some modules that will let a Pi/microcontroller adjust AC power to dim bulbs but since I prefer LEDs for power consumption I am worried about flicker if I use one of those AC dimmer units.
Since I am looking at LEDs, are there any DC LEDs that would be bright enough to use in outdoor lighting? My preference is 500-800 lumens (10-14W LED).
An ideal setup for me would be a DC LED (or series of LEDs in the same fixture) that I could completely control with a Pi, flicker free. RGB would be a bonus, but isn't required.
