They went out of business and my dimmer crapped out with only one grow. I'm stuck with the light for now because I'd like to get my monies worth. I will have to live with moving the light up and down for now, but it's not ideal.
Hate to see TGSC go but their lights are still great, a little pricy which is why I gave 4 stars instead of 5, probably one of the most expensive 300W lights out there but still had great results.
Incredibly powerful full spectrum LED, so much so you need to be careful with the power level during veg and early flower.
Can't argue with results though, huge yields under this light!
It's a shame this company went out of business 😔
