Question: Have any of you experienced a flashing blue light when the fan is running but the lights are off?  The flash only lasts for a couple of seconds.
Document: The motor casing looks like leather almost.The lights are very nice and put out a softer but bright light. I think it's as bright as the fan we had before with 4 downward facing globes. Speaking of the globes, It's nice that you can look up at the fan from every angle and not be blinded by the exposed light bulbs. I wondered about the shadows from the blades, but it's fine. The motor is very quiet.Having a remote is the best thing ever!
Big fan! Looks great and works perfect! Hardly used the  the air conditioner this summer because the fan made it comfortable. Would recommend for large room and comes with remote which changes the fan speed and dims lights if needed!
They're in there, just be sure you don't skip a page during installation like we did. Even if the fan is already up, you can still install the receiver although not as easily. The remote has a light on/off (another review mentioned dimming, it doesn't do that) and 3 fan speed buttons.
Gorgeous fan! Bought this for our master and it works perfectly. It came with everything we needed, including light bulbs and remote battery. Our style is antique, rustic, pottery barn.. I wanted something pretty and unique. It doesn't look "too big".. it doesn't look much bigger than a 54". The detail on the fan blades is really nice - it has a pretty but simple cut out design on the ends of the blades that add a very nice touch.
I purchased two of these and could not be happier. The fan in simply beautiful and so well made. It was really easy to install. took about 1 1/2 hours, but that's with unpacking and removing the existing fan. Having fans which are remote controlled is awesome. I was initially worried about them not giving enough light, I have 12 foot cathedral ceilings, but they give more than enough light, plus the energy saving bulbs are included. Would recommend to anyone.
I hung this fan in my family room. At first I thought it would be too large but it's not. It looks wonderful and very elegant.
The longest one is maybe 8", if that (the others are maybe 2" and 4").. so this wouldn't be good for a vaulted ceiling unless you can buy a downrod separately or you have one that will work with this fan. Can't say enough good things about this fan - super nice!
