Hortilux and Sunmaster are two great brands for lights. If you have the ability to run the lights together you will see that the bulbs that come with the light system will be not as bright (as it appears to us) as the hortilux or sunmaster bulbs will be. Currently i am running a 400mh Sunmaster for veg and 1k HPS Hortilux and 600wHPS Sunmaster for a total of 1600w HPS for flower. The difference between them is very noticable. I think one has the full spectrum where the other doesnt. The lights do make a huge difference.
