The bulb and ballast are both IPOWER... It was a good deal i got 600 watt mh bulb, 600 watt hps bulb, 600watt digital dimmable ballast, and cooling tube with ventilation hood.. Honestly man i could not be more please for only paying 200 brand new.. Lol as soon as i got the tube out the box, i dropped it and cracked it.. I suck..
