These are very effective, we had a professional electrician install them. They are larger than I imagined, but there is no way (at least according to our electrician) to be able to connect a switch to power them on. Also, the blades are very cheap looking. We wanted an all black fan, but if you choose to use the black side of the blade, the brown shows on the edge of the blades and just cheapens the look. Eventually I’d like to paint them black and see if that helps. The fan itself is very powerful and the remote panel is very nice to have, but you’re forced to install the panel as well
