Wicketanswered grow question a year ago i got the xs1500 and its fine, but it's also not as good as advertised. the coverage area is smaller then they say, you need to get closer to the plants to get the numbers they say. so if you want to use it on a area smaller then 60x60 you will be fine. if you got the money get the xs1500 pro instead, its pretty much the same but the lenses got improved so the light coverage is a little bit better and more uniform.
but it all depends on the room you want to use it in. also from where you are, in europe the price is not as good as in usa so there might be other cheaper or better options.
