LED Light comparison overall efficiency

  1. doing a 4x4 in soil started with a dwarf sun black diamond 425w equivalent actual 230 consumption same as KIND model third cost ( not the appollo copy that uses 270w) . wanted a few more watts without spending much so i opted for a VIPARSPECTRA 600 half the cost at 200 . well two major observations . one it uses 250 w and has %20 more light than the 400 dwarf star so that was within acceptance however it weights a bit less . this is from the smaller heatsinks . Dwarf star run temp 77 viparspectra 84 TOO HOT . so even if watt efficiency seems ok undersized heatsinks will be a issue . cooler LED run more efficiently . so now i need to run a fan wich is more watts but my overall wattage for the tent is only 650 total 2 lights exhaust fan and air mover fan and 4 t8 for side lighting
