Hello There, I'm really happy with the extent of the LED bar. Have a total of 4 bars as lighting for my aquarium, since they are water-resistant and much less power than T5 lighting. Had 2 black sheep at where 3-4 LEDs not really wanted to, but after a quick and uncomplicated consultation with the seller I got shortly 2 New. Bin with the strips really satisfied as well as the communication with the seller. The bars are well made and are lit to full. Light with 4 x 60 LED strips, 1x 30 Led strip and a blue LED strip my entire 450l basin (as a guide) Can only recommend this ...
