I run a single lighted screen of 50 cm wide and 8 cm down it is lit by a 55 watt pl 2700k lamp for 18 hours.
Now I order 20 X 3 watt 660 nm leds they run on 3.15 volt with max 0.9 amp I want to burn them at 0.450 amp to make sure the run good for a longer time.
I know two sides light is the best but than I make 10 leds on one side by one side 20 leds.
Must i chance the size of my scrubber ?
It is overflow fed and I use an Eheim 5000 liter pump.
Sorry for my bad englisch.
Greetings
Eric Jan
