A TS 1000 is good for a 2' x 2' area. It's great for doing a single plant; especially SCROG Style. A TSL 2000 is god for a 2' x 4' area. A TSW 2000 is good for a 3' x 3' area & a TS3000 is good for a 4' x 4' area.
Mars makes great lights. The best part is the Drivers are detachable with long cords. You are able to mount them outside your tent, which eliminates some of the heat. I've tried at least 12 different brands of lights. I started with Mars & switched to other brands several times. I'm back to using Mars again. My yields decreased by nearly 1.5 oz. per plant with the other lights. I was pulling 8 oz. per plant the first time I used Mars. So I went back to Mars & wah-La ! Pulling 7-9 oz. again right away. So my opinion is it's the best light for your money.
