Make sure you check out the true watt output! The 240w blackstars only offer 135w true watts at full power. I did some extensive research on led's over cost and efficiency factors so I went with 2 pro grow 180's from hydro hut. They're around the same price, have 14 bands of light with IR and UV, come with hangers, a 3 year warranty and free worldwide shipping. I sound like a biased salesman... Just trying to help a fellow grower out

. One of those 180 units offer a 150-160w true watt output. Two of them would get your desired 300w+ and some decent spread. Should cost about 560 USD shipped I believe. I've been very happy with them thus far. My nugs are rock hard dense and sugary looking! Let me know what you decide on. Always here to help!
