Ditching my HID, but is this LED good for this tent?

I bought an HID but i think i'm going to ditch it and go back to LED. I have a 135w Blackstar lighthouse hydro and i was wondering if its good enough for a tent thats 3ft wide, 2ft deep, and 5 ft tall? of course all mylar reflective inside. I'm only going to do 2-3 grows max in it.

If its not enough should i just supplement it with some cree lights or should i go bigger? after i return the HID i'll have a couple hundred bucks to throw toward another led panel. Maybe a 240w??

That Blackstar fixture is not even close to being big enough for the space. It might grow one small plant. For a 3 x 2 space get one area 51. Sell the blackstar and the HID and put a few more dollars with it and you can get one light that will do very well in your space from veg to flower and cost very little to operate; you won't be replacing bulbs or paying high electric bills for the light and/or to get rid of the heat

You'd probably want about twice as much light. Good rule of thumb, 40-60W/square foot. You can do more or less, it's up to you and you might even get good results depending on the efficiency of the system, but I'm also guessing that that Blackstar isn't 135W at the plug.

I believe it draws around 80-90w. I only have one plant growing right now so i think i can get away with it for this one grow.
