Lights came in good condition no damage and the discount is unbeatable. Highly recommend ledgrowlightsdepot
Purchased A Spectrum King SK-402 LED light last February. I have not one bad thing to say about Spectrum King or Grow Light Depot. The light is beyond all expectations I ever had. I love the fact there are no moving parts. No fans to quit on a guy AND its built rock solid. I know there are folks that consider LED to be inferior. Spectrum King has got it going on. For me this just buries the old Sodium Vapor lights. Less heat and less Juice. win win.
Excellent grow light but be sure to get the dimmer on it. Light is so powerful it has to be set to the placement distance, otherwise it can cook the plants.
I picked up the sk402 with the dimmer option. Simply put this light is badass. If you’re growing in a 4x4 spot this the light you want. Stoked on the purchase. And the company is awesome, happy helpful people. Great in every way.
Definitely a quality product above any Asian LED the spectrum king sk402 with dimmer has out performed any other light I've ever had. My plants love it, my roommate hates it (because of how bright it is) but because it's led, my pocket loves it. The terpene production is awesome on this light too! Definitely looking forward to using the sk602 in the future.
