Katie, – DIY. No wiring was harmed in these simple track installations, only simple wire nut connections to existing ceiling mounted outlet boxes. All you need is a power drill and bits, a couple of screwdrivers, a ladder, and maybe a hacksaw. Just be certain to turn off the breaker or fuse connection to the desired outlets before working. Look for track and conversion kits at big box hardware stores and their occasionally knowledgeable sales assistants. There are many track installation videos on YouTube, which should convince you how unnecessary even they are. Track may also be cut easily, if necessary (with hacksaw), despite general advice otherwise. Get your toolbelt on girl!
The previous pic was from a super oblique, todler's eye view, straight up from the stairwell's first landing to the open rectangular fixtures. I normally abhor salon style hanging (vertically stacked pictures), but a stairwell is an exceptionally difficult environment aesthetically, which coincidentally includes an incredible amount of wasted blank wall space.
Here are two views of what good track lighting can accomplish, given a normal room in a home. The first is of the dining room, where a repulsive chandelier (IMO, chandeliers are ugly and ostentatious) used to light the entire space. It was removed and a track connection installed over its outlet box in its stead, in the middle of the ceiling.
The track was extended another 16 feet (using the same switched connection) in the opposite direction in oder to light the opposing "living room". Spot fixtures may be aimed in any direction to any wall from the center line of the ceiling track. General lighting is now accomplished with table lamps. All other lighting both inside and outside the house have, by now, been converted (i.e., green) to either CFL or LED. The incandescent art–specific track lighting (i.e. not so green) is normally used only to highlight the art.
