This light has proven its value for me over the last year. I started growing with this as my primary overhead light. I then upgraded to a more powerful spider farmer EVO. But I found I had under powered my purchase, so I thought that if I use my sf600 as a side light it might solve my problem. It is working great for me, so much that I just bought another 600 for the same purpose.

Used to germinate and for seedlings. Excellent light and great for the cost. Been running 18hrs a day for a few weeks with no issues so far.
