I've been using the mega 1000 in a 78 inch by 78 inch by 78 inch tent for a couple of years now,With two sp250 led lights from Mars hydro,And two 200 watt Cobb lights and pulling a couple of pounds every 50 days.
I bought two and they came packaged very securely and arrived in perfect condition. I just hung them up and it was so easy which is important to me because I am older and these were light and easy to handle by myself. The light they emit is amazing! My plants love them and so do I. I plan to buy more in the future. The warranty is also great!
