on the search for a replacement, I came across this listing and slammed hab. the light Mitel is for two days in operation, you realize only minimal difference to its predecessor with 300W, almost the same light output with a pleasant shade. then I got here sometimes interposed a consumption meter on the basis of contributions. This light bulb actually consumes only 171 W / h, ie just 20 watts less as the manufacturer / seller described. and the dimmable (also means self-consumption and losses). no hum / dimmgeräusche, absolutely silent. I am very pleased. absolute recommendation.
