Honestly you will get fine results and the bulb your talking about doesn't have the uv blue spectrum that than other bulbs were talking about combination bulbs that have a hps bulb and a mh inside the bulb splitting the power depending on the model of the spectrum
1000 watt combo roughly 600 hps/ 400mh inside the same bulb
you will have an increase in weight of crop w/ a hps or a enhanced which has a stronger orange red spectrum than a normal economy bulb
but w/ the combo bulb you will have a slightly smaller crop usually but will get extra frosty from the added uv direction in more ballanced spectrum
Bottom line you can obtain very good results w/ a plain jane economy hps,
But... this is just one of thoose tweeks that boost plants
when flowered under a broader spectrum i have a sweeter finish and a less woody taste than grown under straight hps
