First of all these headlights were WELL packaged and in perfect condition. THANK YOU SO MUCH! Bought these lights for a basement project that is only a few inches from recessed lighting. And they fit the bill! BIG lumens for the price and for the amount you get (I bought 12 packs)! The lights come with a cut-out template for easy cutting of drywall or ceiling tiles. For the installation you need some basic electrical skills as you need to connect a switch or dimmer to it and you need to know how to connect them in series but in general. VERY easy to install!. VERY happy with these lights! HIGHLY recommend, especially if you are looking for a low profile lighting system for a solid fit. 5 Stars!
