I now have the fourth Sunstrip lighting Econlux and I have to say truly that this LED lamp is a real alternative to conventional tube lights. Looks modern, hardly consumes energy and is extremely durable. I'm using a control computer in conjunction with other LED lights and can so sunrises and sunsets, midday cloudiness or Mondlichphasen control gently dimmed. Processing via Amazon and Bonn-hunting were really super. Very fast shipping, thank you very much. Strong buy recommendation.
