Because the walls and ceiling are dark Japanese-style rooms, I purchased it as auxiliary light in the corner of the room, or as indirect lighting. Immediately after turning on the SW, it is a light bulb color, but as time goes on it turns into white light. Even though the main lighting is a light bulb color, because the corner is more noticeable with white light, I replaced it with a bulb color LED. It is unnecessary so it is the corner of the work place. I use it for the constant lighting of a dimly lit place.
