Question: What is the difference between the white roll and the black roll?  RGBWW and RGBW?
Document: after two weeks of use the color white would not be white it is now yellow and the remote works when it wants tobut for the money not bad.
These LED strip lights are awesome when they work. I'll have them on the FADE 7 mode which works for a couple minutes, but then it automatically switches to a simple white flashing mode and stays there.
These lights are great but be aware that these don't come with a power supply. You will either have to by a 110v to 12v power  supply or cut the end off an old power supply adapter you have to connect the white box to a 12v power source.
I needed this to extend the wiring from the outside of my trailer to the inside. I loved that it was white and you cannot see it against the trailer where I fastened the lights as it matches perfectly. It's plenty long enough and felt durable.
The other 'kit' I purchased was the exact same thing - same light strip, same small white controller, same battery included remote control, and was just a couple bucks more than this. Rather than hassle with returns I've examined two of five so far, and both have faulty remote controllers, or RGB controllers, not sure which. The light strip itself is great (bright, coated with thick clear coating), but it only turns on but won't change color or turn off without unplugging.
These are awesome, waterproof, easy to install and too many light configurations to use in my lifetime. my only complaint is they didn't come with the plug that goes into the white box. It needs to come with this, so be forewarned and make sure you order from a company that supplies these or you will be making unwanted trips to Radio shack  to cobble something together  I just happened to have extras from a previous order from another company you can string at least two together on one power supply
use the right Voltage and AMP.. one roll is 12V and 5A max.If you would install this in an RV or want to pimp your car, always run this thru FUSE..  Never use direct battery connection... Fuse prevent product damage and most importantly, prevent fire.I have installed this under my car and under my dashboard.. Im telling you, it's awesome!
I like the like the RGB LEDs! the little controller works very well for the price, a few other fun tions could havebeen included for no more money. Now getting to the LED strips. I bought 2 rolls, the first roll that I tried to use had major problems with the clear coating covering the LEDs, it also had major problems with the 3M adheasive.. that was totally useless.
you can tell they've been built cheaply, but i guess that comes with only spending $20 on leds! Very bright and I love the remote, it's a very nice touch! Disappointed they didn't come with a power cable! good thing i had extra parts around.
works very well and rather bright! however the pictures are misleading because it shows it being able to be multi colored, this is incorrect. one color at a time only. the customizable coloring is awesome though. bought these for bed lighting in a project truck. very hard to solder them together though. took over three hours to solder 3 ends together. would buy again if the future calls for it. overall happy besides the fact that the 3M adhesive is worthless.
Answer: no
