Dual arc lamps are great for both VEG and FLOWER, you could just use a MH on its own for VEG, but in FLOWER a dual-spectrum/arc is the way to go...HPS will make big weighty buds and MH will make them more resin-ny and smell better...So to have both in one lamp is defo a good thing heck throw in a UV-B lamp and you'll more or less have a full (usable) spectrum of lighting, and UV-B will excelerate the ammount of THC/THC-V that your lady/s cover themselves with, hope that helps - ZTELTHY
