If you want to be annoying about it, white LEDs use a phosphor coating to generate light, making them technically fluorescent lights. Also heat is a much bigger problem with LEDs than is obvious, they become less efficient and burn out faster if they get too hot. Heatsinking gets real important when you get above 3 watts or so. I have a 50w module that I bolted to an old CPU cooler and it still needs a fan.
I do have a bunch of home automation lighting and stuff. I've found it's basically impossible to find products off the shelf that do what I want so I rolled my own with openHAB and some ESP8266 microcontrollers. I have programmed in failure modes for network and sensor issues, and MAC filtering blocks the nodes from doing things they shouldn't. It's kinda nice but I can't really recommend it unless you can think of something better than "turn on/off a light with my phone" for it to do.
