Special LED transformer almost essential. Despite the warm white of qualification remains fairly cold or slightly greenish. Listed reliability is the Berezina: One has never worked. One has laché after 10 min One began to flash after 2 months A few minutes start flashing. Both work (for now) correctly. The others are not tested .... It'll be hard to average 30,000 hours with that! . Edit 29/11 In practice, none held so full of more than two months. Cheap, but quickly in the trash.
