I have to admit I'm addicted LED! I want to trade all in LED! I am Objektleiter a commercial kitchen and have my time just, in a year, the investment by energy savings back into it. OK, the light is not so nice and warm, but there where neon lights are in use, it does not depend on warm light! First we tried LED office. At the light you had to get used to, but over time it bothers any more. And we have found the LED tubes are even a little brighter, so we only used half of tubes! This one we have used in the great hall, the same principle, only one-third used again! OK, that was grenzwärtig with the power of light, yet sufficient, it is still bright enough. When installing no problem! The bypass starter is at with and those things are at once without starter effect!
