Wall washers are denatured products of spotlights, so they are also called strip-shaped spotlights. So, what improvements have been made to line lamps relative to spotlights? First of all, since the shape changes from a circle or a square to a strip shape, it is more suitable for mounting on a wall for a wide range of projections, sacrificing the distance, and in exchange for the brightness of the width.
This looks like the wall is bright, the effect of the wall washer is indeed better than the spotlight. After all, the advantage of the spotlight is the illumination of the column and the long-distance illumination, which is suitable for the illumination of the upper floor, and the effect is good. There is also a star classification in the wall washer, which is the line light.
The difference between the line lamp and the wall washer is that the LED chip is used as the power source, so the wattage power of the line lamp is generally 15W. The advantage of the line lamp is that it can outline the outline of the building and the beautiful lines of the wall. Because the lumen lamp beads are not used like high-power wall washers, there will be no range illumination and the lines will be very beautiful.
