I wanted to try out the new Gavita 1700e or the Growers Choice 680 LED but my tent is only 4×4 and those fixtures would be a tight fit so my friend recommended this fixture. Similar design, no moving parts or fans, just passive colling and great even coverage. Low heat and overall a great product. I will probably be buying more when I expand to a 8×8 or 10×10 tent. I highly suggest giving this light a chance
