As I had expected more after the sebson G4 Lämpen were quite good. These lamps are neither warm white still have a brightness of 360 lumens. If they are used instead of 360 lumens standard energy-saving lamps, which always need 2 minutes until they light up fully, you notice the difference immediately. The Sebsons make an even colder white light, which is not unpleasant, but not warm white. And certainly not bring the promised performance of 360 lumens, they seem downright funzelig. I have tried this against 3 different types of standard energy-saving lamps with 360 lumens, all were brighter and warmer. Therefore, kicked back at the end of the sebson. As I find myself rather so from that other lamps need something until they are warm and make a pleasant light.
