Admittedly I didn't actually look into these lights prior to purchasing them, I just needed new lights for my daughters room since their last set were useless so when these arrived I was amazed by the multiple light modes and the bonus that they aren't battery operated (USB lead) makes life all that easier.
The lights themselves are on a wire making them easy to manipulate to how you would like them. Numerous flashing modes - rainbow, gradually fading, racing, options of light staying on in red, green or blue and 3 modes that flash to music. Has a timer 1hr, 4hr and 8hr. Light dimming/brightening options. Easy to change between modes.
You can link it up to your phone which provides you with the chance of choosing your own colour settings
Can't fault these lights and will be purchasing anither set to go around the kids room fully
