Took some spectrum readings of the light last night, interesting to find these results. In both tests the benchmark line is 8x54w T5 tubes (B,W,B,A,B,P,W,B)
First chart shows all T5 and all LED - the addition of the LEDs give a massive kick in the blue
This chart shows just 4 T5 tubes on and LED - interesting to see how intense the light is with half the tubes running, apart from coverage potentially only need to run this setup and save power on the full 8 tubes running
