I bought the lamp for two different Christmas lighting scenarios. On the one hand for a wooden window frame and on the other for a Adventsstern. The brightness is very good and the color of light is in my view equivalent to that of a normal light bulb. The brightness is very good, but is more suited to window images and Advent stars that swallow a little more light. For Windows images that are more translucent, the light is probably a little too bright.
The luminaire can be screwed well. The indicated dimensions are in very good.
