I purchased two (2) SPF2000 when they were first made available. I only grow 4-5 plants at a time & needed to upgrade & replace my purple light emitting units. I had always considered the 'open' type LED light fixtures as 'Professional' & not suitable to my needs. I was wrong. They are good for everyone. Once you think about it, the 'open' type, makes more sense. More light penetrates to inner buds better. After germinating, I placed 5 seedlings, one each in a 5 gallon cloth container, under these two light units along with my Sonlipo SPB2000 (No longer available) purchased a year ago to control the lights. My seedlings look very happy & I am too. The price was very appealing, no 'purple light' washing room, no fan-no noise, much less heat. Features include off/on, one each veg & bloom off/on switches. The one thing I don't like is no UV diodes. I have read where some claim this is not important or needed, but I like UV. Even so, I am definitely a happy fun filled Sonlipo customer. I had several times emailed Sonlipo for some help & they are happy to respond. I had found a 'Congratulations - You are a winner!' card in the box when I received my lights. Sonlipo sent me a beautiful 'smoking set' worth @ $40.00! Give them a try. Grab some SPF2000's before prices go up as inflation right now is terrible. Good luck & have fun! UPDATE: I just received my 3rd SPF2000 LED light unit. My plants look so good this time I felt another unit will produce bigger buds. Sonlipo is producing high quality LED light units for a very reasonable price. Check them out. Sept.2022 - Just had a real nice grow with my Sonlipo SPF2000 LED light units. I am very happy with the results of my 5 different strains. These lights work very well for nice tight big buds. The original cost & the operating costs were much lower than other 'high priced' LED units the same size. Happy growing!

These lights have all the choices!! I have other grow lights and these ones are definitely heavy duty in comparison! If you are a serious grower these lights are for you! I would say they are a bit bulky for my needs, but again I think these are very high quality.
