The LED profile GK18-3 is designed to be inserted into milled or cut holes. It can be used on any surface (walls, ceilings, etc.). The lowered wings allow for an aesthetically pleasing application of plaster flush with the wall surface. Due to its increased height compared to the GK6-3, it is used where a uniform line of light across the entire surface is required (the point is free). It is used, among other things, in interior finishes.
