The LS Series is a collection of small LED steplights from Engineered Lighting Products. Designed for trimless installation as an indirect light source, the collection provides a wide distribution of soft light. After installation, only a 1-3/4" by 5" lighted opening is visible, and the aperture allows the wall finish to end right at the edge of the lighted opening. The LS Series can be installed in either 1/2" or 5/8" gypsum board construction. The 4W fixture has a formed diffuse silver reflector made of aluminum with a 97% reflectance and uses a 3,000 K driver.
