The 105 ft version contains a whopping 1120 individual LEDs. But the amount of energy they consume is quite minimal for the length and amount of brightness they emit. It only pulls up to 42 watts when plugged-in. 

It is completely sealed for water, from head to toe. And the backside isn't adhesive since the stickiness likely wouldn't last long outdoors. It is designed to transform your space with a vibrant light that reflects the mood or adds aesthetic. Whether you want to transform your space for holiday, party, or a date, it can help you setting the desired atmosphere instantly.  

With built-in IC controller, various colors could be changing simultaneously in one line. It looks like the different color leds are chasing, skipping, dancing and twinkling. It emits a rainbow of colors while a section races through the strip to alter and morph the colors. While all of the effects are adjustable through the included remote or downloadable smart app, this dazzling effect is definitely amazing.

Installation is very easy. It includes a complete set of accessories for installation. Please note the backside isn't adhesive since the stickiness likely wouldn't last long outdoors.

You're able to install them by using a buckle/pin every few feet. While you can't extend them beyond the set lengths, you can shorten them and seal-up the cut-end with the provided glue. This will assure a water-tight seal so they don't malfunction if exposed to any moisture.
