I second the magnetic core design for the ballast. One downer w/ mine is that the cords are fixed in the ballast, they do not unplug, but I get by. Also consider whether or not you want an enclosed AC hood, also pay attention when buying, some come w/ bulbs some don't, which may account for price differences, also keep in mind shipping if buying on line.
8182KSKUSH Reviewed by 8182KSKUSH on . Criteria for 400hps purchase Just a quick google search yields such a variation in price for a 400watt hps light setup. What criteria should one look for when buying his first 400watt hps light? I'm just wondering if the extra price of some is justified or not in a few brands and prices over others. Thanks Rating: 5
