In this video I'm taking a look at my new toy, the Mars II 400w LED Grow Light from Mars Hydro. I picked it up from www.mars-hydro.com/
It's a good value unit with a power draw of around 185W, it uses 80 x 5w LED's in 6 different light spectrums. 430~440nm, 450~475nm 620~630nm, 650~660nm, IR 730nm , and white 5500k (full spectrum daylight).
The light output compared with the 270w DIY CFL grow light I built in a previous video is substantially more intense. You can check out that video here: • 270w DIY CFL Grow Ligh...
Also compared to the 96W DIY LED Grow Light I built in this video: • 96w DIY LED Grow Light... it has a better spectrum and more intense light.
It's a serious piece of kit and I'm looking forward to growing with this light over winter.
