What my good buddy slothy is saying is that the fluorescents that come with that kit on ---- are Normal Output fluorescents. Not Power Compacts or any other type of High Output. They'll give you about 20 watts each. And the 5200 K metal halides will DEFINITELY need to be replaced. I think 6500K is about the minimum K rating that reefers use...and then they supplement with actinics...and NO's are fine just for the color, but you won't get much added light/lumens from them. And without any added fluorescent lights, most people buy 10000K MH's or higher. So...looks like that bid is up to about $140...then add about $70 per bulb to upgrade the MH's...you're back to $280...which actually wouldn't be too bad...if the bidding doesn't go much higher.
