i originally switched from MH to LED for the energy reasons, as i was in an apartment and was blowing breakers, but with a multi LED setup, the MH would really just be there for supplemental light for maybe like 4 hours a day, not full time.I agree. If OP is going to use MH's be prepared to spend for cooling and ~$300 every 6 to 8 months for good bulbs not to mention a hefty electric bill.
Hence reasons I went LED on the one I showed. In fact, I went LED on everything but admit I miss halides sometimes.
