About 2 years ago I started to switch the lights of our house on LEDs. Meanwhile, I'm done except for one lamp. All 220V lamps have got different LED inserts of sebson (35 bulbs). A single LED was defective upon receipt (the glass envelope fraction) and was replaced without difficulty. All others do still their service and save daily electricity. In my 12V lamps (with transformer), I had to improvise in order to also replace not all transformers have. It has in all lamps (3-5-burner cable systems or Rondelle) passed, ever let a halogen lamp in the system and to replace the other spotlight against sebson-ED's (20 lamps) - is working properly. Again, there is so far no failures. In the brightness I had partly readjust and use depending on stronger or weaker bulbs. the light color is pleasant and can be used in every room - a matter of dosage. The sebson LED lamps have been proven clearly and should pay for itself in the foreseeable future. Unique buy recommendation.
