GODOXTL30 RGB Tube 2700k-6500K Adjustable,13 Fx Light Effect, Magnet Design 4-Light Kit

I tested these this weekend with a Sekonic C-700 spectrometer and the kelvin values didn't read exactly the same. They seem about 500k warmer when you are trying to get 5500k so I had to set them to 6000k. Having said that, after they were on for a while I had to set them closer to 5800k to get them close to 5500k.1hr is a decent length of time but I wish it were longer. I assume that you can find a way to plug in usbc power to AC through some kind of converter if you really need it.You can also see the individual leds in reflections vs. a single tube shape.I do like the size of these and the power output.Still not sure I am going to keep them though if the temp values aren't reliable.The knobs are very intuitive, for what it's worth. I never could get the app to work so I gave up using that.

Feature packed lights however I don't believe the t30's work with the music fx from the app. Also battery life is pretty quick
