We installed two of the "warm white to multicolored 640LED" sets today. So far I'm impressed. A few remarks:- We connected two strings together end-to-end (running off of one power supply and controller at one end). The brightness only goes to about 80% with two strings connected, which is acceptable to us.- The remote is infrared, not RF, so don't expect to use it through a wall. Still, the remote is very useful.- Each LED is a two-element LED, containing a white LED and a single-color LED (one of red, blue, green, or amber).- This is a two-wire system; it's not an RGB set, and it can't be set to chase or to a specific color. All of the modes are some pattern of warm white, multicolor, or a blend of the two, which is a pleasant effect.- The second connected set operates in the same mode as the first set, which is what we hoped for.- Flicker is very minimal.I'll try to update this review if we have any problems.
