Watts was a typo. They're rated for 16 amps so at 5V that's 80 watts.
I see the light now! The RGBW-NW part had misled me. 
LS4P high power addressable controller is fine with SK6812!
I'll just need a larger 5V power supply since the one I have is only 40W.
I have this 16w one
16w should be 16A...
Athom has 4 or so different models...
I have this 16w one without white: https://www.athom.tech/blank-1…ower-led-strip-controller
This is the 16w RGBW model: https://www.athom.tech/blank-1…bw-light-strip-controller
I could change to HD107s on my LS4P-WLED but would need the LS5P-WLED model to use the SK6812 strip.
I have noticed a response difference with the WS2812-60/m-12V vs the WS2811-30/m-5V I had before but I think that is possibly due to the number of addressable LEDs/segments? With 2811-30 I had 114 addressable LEDs and now with 2811-60 I have only 76 addressable segments. My strip length is 3.86m...
SK6812 RGBW best colors.
Problem is my current controller is Athom LS4P-WLED High Power LED strip controller...
SK6812 RGBW-NW
Why did you choose RGBW vs RGB?
I have made the change on my ambient TV lighting from WS2812 5V individually addressable LEDs @30 per meter to WS2811 12V @ 60 per meter but which address 3 LED's/segment (which took me a while to figure out what was wrong with the LED count!). I am wondering, for a 55" 4K TV, is it worth it to change yet again to WS2815 12V @ 60 per meter individually addressable???
