  sounds good to me, but is it?

that would work great,even more better if you know if its a sodium vapor bulb

The bulb life on that was listed at only 1000 hours. That's not very much time, considering most HID bulbs have a rated life of 10 times that. Granted, you have an exponential drop in light intensity as the bulb ages but nonetheless, it doesn't take a rocket scientist to figure out that one of those bulbs you are attempting to buy won't even last an entire grow. Why not make a little extra investment now and get yourself a 400 watt HPS, which will last you 3+ grows?

Just my $.02 though.
