3 lamps of this type illuminate our kitchen, my big worry beforehand was that the dead zones of coverage are too large. Need not have worried, the illumination is very good, the light output hervrorragend. Are actually brighter than the conventional 50 Watt halogen lamps. And 134.1 Watt power savings are also not without.
The light color is a bit sterile and cool, but this also colorfast.
The lamps have a minimum delay to, a small blink and then it is suddenly bright.
