whats the advantages and disadvantages of booth sources of blue light i was always impressed with actinincs and thats what i use but is 7500k better?TIA Jc
Bulbs labeled actinic 03 should spike in the 420 nm range which is better for corals. This is supposed to simulate sunlight at about 30' depth in the ocean. The blue bulbs are (I think) around 450 nm.
