600 watt hps vs 1000 watt hps . and best bulb vs cheap

what are your opinions ? i use both 600 and 1000 . plants seem to look a lot more sexy under the 1000 and the light area is quite a bit more . can raise the 1000 up get a very nice 4/4 area . the 600 a 3/3 but not as intense lighting . i need to add a few more lights debating on 4 more 1k over 4 600 regardless of the electric bill . the 1000s are 125 bucks more a month the amount of light i think so much more for the 125 a month . no need to concern over heat venting it out side cool tubes . its so damn bright i cant see shit in the room right now . what are your opinions i think im for sure dropping some cash on the 1k .. i did not want to start to different threads almost the same topic . i use hortilux and also use cheap as shit i power hps . i am not seeing much of a difference between them . not a lot of experience with the cheap 15 dollar bulbs the plants respond very well to these ipower bulbs anybody play around with different brand name bulbs ? all my ballasts are solis tek digital .

I have used hortilux bulbs and cheapo 20$ bulbs, not a huge difference if you replace your bulbs a lot besides the price tag, the hortilux work slightly better for veg in my opinion.

Apollo bulbs for last 4 yrs. At their price point, I change the bulbs every 69 day run.

currently have a hortilux 1000 65 dollar bulb well some people pay double . vs a chap i power 18 or so dollar 1000 bulb sitting right next to each other same every thing plants the same . we will see any difference at all . so far nothing . and nothing i can see . i dont have thousand dollar equipment to test .
