The delivery was fast and well packed. The three LED Strips enough to dive a 240L tank in muted blue light. However, have also stated in the reflector of a fluorescent lamp, the LED strips. A separable connection between power supply and LEDs beneficial would have been for this purpose. By LED lighting I now have the opportunity in disconnected daylighting to watch the activities in the aquarium. Unfortunately held only 5 weeks. LEDs defective!
