- CUSTOMIZED DIMMING DESIGN: Upgraded SF series growing lights have a dimming knob and light switch. A single light can be adjusted to the light intensity at liberty. Multi-light Connection with unified dimming is especially beneficial for large areas of indoor growing and commercial planting.
- IDEAL FOR ALL GROWTH STAGES: Excellent full-spectrum- white, blue, red, and IR (3000K, 5000K, 660nm, and IR 760nm). 3000K diodes provide more reddish light and 5000K provides more blueish.

So I run a perpetual harvest as a caregiver and we harvest every week. We are currently using HPS in our flowering rooms and dual spectrum in our veg T fives over clones. I purchased a 10 x 10 tent and to SF 4000 spider farmer lights. So far I am pretty happy I’m only going to run them on half the 10th feeling that I need to have another two to be able to cover the other half of the tent properly. I only gave it four stars because when I’m boxing the first package both of my Meanwell ballasts I had been knocked off the back of the board and had to be re-screwed back on but I believe that had more to do with shipping then spider farmer as their packaging was very nice. The lights are significantly brighter than I thought they would be and I am a little skeptical on how many plants you can put under one of these lights so I will be placing one plant under one light and five plants under the other as soon as I can afford it I will be ordering two more lights really hoping to be able to replace my large room with these LEDs when it’s all said and done. I am also looking forward to ordering the control board I currently use something similar with my HPS system and nanolux
