I recently just bought the Chihiro WRGB II 30cm and it has an annoying coil whine present if the dimmer is in use (its very light but noticeable). I have already returned one units and the second one is the same. My question is if anyone else has this noise, and if so, is there a way to get rid of it or is this just how the unit is?

I have a wrgbII pro (120cm) and it is totally silent. I'm very sensitive to whines so would notice anything.

What dimmer are you referring to? I have the WRGB 2 Pro and there's been no issues so far....ramp up/down is managed thru the app
