Been using Spectrum King lights for years. This new one is the King, Crystal production is much higher than with HPS. Wish I could afford more.
So far, so good, we’re only 2 months into 1st grow with our new lights
I've grow the same strain seed in two different tents using Spectrum King LED SK602 in one and Advanced LED in the other.
The SK602 got the plants growing more rapidly, greener and more buds by far.
I will be buying more of these lights to replace the Advanced LEDs as they die off. I've not been getting any support from Advanced LED for replacement parts so I'm being forced to find other light sources.
Great quality, well built and they work!
Wonderful and super powerful light that produces top quality harvests and with the dimmer it becomes even more versatile.
Have been very impressed with the performance of this light, Have been using with a light rail mover.
