Tubes have their place but sometimes its hard to beat a nice silicone coated strip. These strips are made with SK6812 RGBW chips on a semi rigid strip with 3m 2 sided tape to help secure it (20" variant does not come with 3m Tape). These can be cut every 3 leds, just follow the markings on the back. There are solder pads every 3 leds on the back so you can add outputs or cut a strip into multiple strips to help you maximize options while still having the clean coating.
