I just purchased the 72" outer orbit metal halide pc fixture. My two questions are; #1 on top I have four round holes that look like fans, the first three starting from the right are blowing air out, but the last one doesn't blow air out or suck air in?, #2 it has dual actinic (460/420 nm) pc's, one side lights up blue the other looks possibly lit up white. Is this correct?
