The delivery was very quick.
The lamps can be distinguished in the feel not of much more expensive photographic lighting. The styrofoam packing is well suited for transporting the bulb. The light color is ideal for product photography. I could not detect any differences in the color of light. The white balance of the camera works with the lights well. Only the light output could be slightly higher. The value for money fits. For life can be after about 20 hours hardly say anything, but there were also 4 lamps far no failure.
