I have previously tried several very different LEDs of noNamespaceSchemaLocation and brand manufacturers. The sebson are the first with whom I am pleased. What pleases me the more, as it also still the cheapest ones. :)
Were promised a light output of 30W incandescent lamp with only 3.5W consumption. The 30W are mE even resorted rather low; my 35W halogen lamps seen in direct comparison a bit gloomy. The 3.5W I have not measured it, but the direct comparison of the heat development is breathtaking. If you hold your hand directly in front of the radiator, one notices almost nothing. When halogen spotlights on the other hand, the hand heats within seconds on painful.
A promise was also warm white light, and the spotlight also provide clear warm white light. What not to do: to provide identical lighting to halogen spotlights. The mixed use of halogen and LED lamps in the apartment is therefore somewhat problematic. Judging from the halo in the LED space, so the LED light looks artificial. Going the other way around from the LED in the halo area, the halogen light rather sombre and funzelig. I am sure that you will hammer out an even more homely tone in the future than in the sebson LEDs. However, this is criticism at a high level: I know the energy saving lamps have to mention clearly more annoying than the light sebson LEDs, from previous LED models entirely. And about the pollutants that get the better in the room when a normal energy-saving bulb breaks times, you may prefer not to think too much ... I'm glad that I thank these LEDs now permanently may refrain me something into the house to pick.
Uneven lighting behavior of the individual radiators with each other, I could not tell so far, nor decreasing performance or defects. The light is available instantly when you turn. All this is in LEDs unfortunately not self-evident.
Conclusion: a good, everyday use product at a reasonable price. Took you long enough! :)
