A typical home track spotlight can be attached to a plasterboard ceiling, but the location of the keel needs to be found on the plasterboard, or a strip is placed behind the plasterboard to eat the nail. The LED track spotlights are used for local illumination. The projection distance is 3-4 meters. The installation distance before the conventional track spotlights is about half a meter (0.5 meters). The specific distance is adjusted according to the density of the objects hanging in the store. The direction of the illumination can be freely moved and adjusted on the track strip, and the installation distance of the track spotlight from the wall surface is also preferably half a meter.
