Hey there,
I just recently brought a Ventair skyfan DC with light. the fan was installed in a 3x4m room with a 2.7m high ceiling. This is the 48'' (1200mm) version (smallest one). i had two of these installed in my apartment.
I am uploading this video just to help you guys out their understand how the fan works in operation. I went to around 7 different stores, not many of them actually turn them on and let you test it. So here is a video of it in operation!
Sorry, not the best camera person!
Overall, its a fantastic fan, its been installed for over 2 weeks and I still don't have any issues with this.
The feedback i received from two electricians, this would be one of the easiest fans to install and by far of extreme high quality.
On the lower settings, the fan is whisper quiet, the lighting is nice and bright and allows 3 different lighting types (Cool White, Warm White, Neutral White).
When videoing the lighting intensity for each lighting type, it didn't come out too well.
The only problem i have with it is every time you switch intensity levels, it makes a really loud beep; there is no way to lower or turn off the sound.
you'll understand when you hear it in the video.
