I have read all the reviews and well appointed last but not least ... Delivery went smoothly. Unwrapped, read instructions, cable zusammengeknibbelt and put together ... ready !! No Problem. Recognized deducted Now to the "notorious" film tape ... and stuck. After the LED strips were heated due to the lighting, the first 5 cm of the strip came off again. To fix, I fixed the ends with two clothespins. After a certain "pressure time" now holds all bombproof! One can actually be glad that is not equal to stick the strips to uncorrectable's first time! Now the light - My pool 150 x 60 x 60 cm = 540 l I have attached the strips on the left and right under the central glass walkway, a rear and a superficial, everything about 3 cm above the water surface. The light irradiation after 22.00 clock is perfect !! Diffuse deep-blue, (somehow it made me equal to "The Big Blue" recalls) radiates nicely and evenly. The radiation is from top to bottom in a fan shape, are from 150 cm 100 cm illuminated (at 60 cm depth!) However, there remain plenty of dark areas of my "Frühzubettgeher" ... and my "night owls" can now be observed in peace on their raids! The fish like it, I like it ... that's why 5 stars
