Review on JULLISON Recessed Downlight Junction: Industrial Electrical Solution with Directional Capability by Eric Garron

Fairly easy to install. I've done it myself. I have some experience installing recessed lighting in my home so this was easy. The hardest part is straightening the wires and installing the switch. I can't go into all of my "tricks of the trade" for this type of thing. If you cannot manage the installation, hire an electrician. A tip for DIYers: do yourself a favor and get them a properly sized hole saw (110mm/4.33in, $12.59 at Revain). This saves you the hassle of cutting perfect circles with a standard sheetrock saw.
