I have 2 lamps "Spiral Photo lamp energy saving lamp 65W" gained to photograph it. Unfortunately, they did not bring the hoped-for performance. The lights are bright so a lot lighter than the conventional energy-saving lamps, but not suitable for picture taking really. How does that now calculate or estimate what would be coming at 65W power consumption than light back out I do not know. However, when I mean 23W energy-saving lamps (1400 lumens) are look in the kitchen this not even twice as bright although one might expect the almost threefold from the feeling by far. However, the lamps have a smaller base as some other lamp with only 23W. It's a 27er base but I've fought with many a lamp because there was not enough space in or near the socket, there is one time every har mm. So I will now not use the lamp to illuminate at shootings, but will find a suitable application (patio lighting, ect.). The shipping was quick. The lamps were offered to take pictures, are, unfortunately, ehr useless therefore there with a lot of goodwill 2 stars.
