I had my two of the 7-watt LED lamps as amended E27 come because I need very bright work light for a large desk. For this purpose I have decided for the version cold white light, as warm white light is slightly more for ceiling lighting in the living area, cold white light all the more suitable for working at the desk, such as several hours studying books with small print or fine mechanical work on small parts ,
The two LED lamps I have screwed into standard clamp Table lamps. I was pleasantly surprised by the enormous brightness of the lamps and can only highly recommend each LED enthusiasts. They are supplied in a blister pack, which in turn puts in a matching small cardboard.
