The light you have linked will be good for about 2 plants for full veg state...
Maybe 3.....if you can keep them short.

Those housing reflectors generate much back radiant heat which can prohibit getting them close enuff to do the job.

Get three of those 200W lights, without the silly housing units.

You can do 6 - 9 plants with three of those...for about 2.5 years.

Also do not buy their mogul base sockets. They are charging 43.00 and you can get them for 15.00 from insidesun.
