I bought these last week when they were only in store and they work great. They have two sets of led's on them; one for RGB, and the other for the White setting. The white is a Warm/Neutral color, and does not have a blue hue to it.
It is a 24V system that comes with three 12' strips with connectors built in, and strong 3M adhesive to attach to surfaces. It's also weatherproof (the strip is dipped/coated) for those needing that option.
I'd say these are superior to other deals from Amazon or Newegg because it's a 24V system and the power brick/transformer has loads of safety certification stickers on it. The 12V deals that come from amazon always worry me for safety if you plan on using them to run long lengths of strips.
That, and the IR remote has reach at least up to 20-25 feet in my house. I haven't tried any further because that's as far as I can reach from where the lights are currently installed.
Electrical Info: The transformer is rated for 24W (24V @ 1 amp)
Costco Item Number 707405
For those that care or plan to have large gaps in between strips, it is a 5 pin setup.
They also had plain white rope lights, that I think were cheaper, but I don't remember how long they were.
