A very bright E27 LED bulb in corncob format. I have therefore the energy saving light bulbs replaced in the hallway ceiling lights, the lamps work very well and provide a bright light. Despite warnings from the manufacturer, I have these lamps mounted in closed glass lamps with approximately 4L volume, the temperature is sure to be something higher than the manufacturer's recommended 40 degrees C.. I have these lamps already several weeks every day, with more than 6 hours without an abnormality in use Unfortunately, the durability can be beurteillt properly only after several years.
