Lightme no stroke is better than other ESL. March 2013 4 pieces screwed into a ceiling light and was thrilled for quick start and brightness. After 3 months already Wars no longer so brilliant ... After 6 months, 2 half blind, 1 shortly before the heroic (starts extremely langsaaaaam) and 1 has completely abandoned. Allegedly, the lamp lasts through 30,000 switching cycles and / or 10000h. Never ... I hope the LED technology makes rapid progress, then the ESL nonsense is over.
