I prefer just to place it based on the what lighting it came from if from a captive grown or if wild I place the frag on how much light ot would get in the wild...
I put maricultures under as much light as I can. Only if freshly imported though, same with wilds. And I do not use LEDs so I can't help there. Big difference between a lot of light from a halide or t5 and a high powered led fixture which could need aclimation.
