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.
Received the light within a few days of ordering and had a pleasant experience with LEDgrowlightsdepot(I had to change because I forgot to add dimmer which was very easy(caught this almost instantly), I also received follow-up from what seemed like a real person in addition to the contact over dimmer). Back to the light - packaging is sufficient, wouldn't expect to see many issues doa due to S&H. Light is in a 4x4 tent and appears to be filling the space very well. The light design wise is definitely more commercial which I like. Cooling is rather efficient as it runs much cooler to the touch than my 100w cob single fixtures. Temperatures on surfaces your hand could come in contact to are running 10-15 degrees cooler than my cob fixtures(rep brand). ***Get the dimmer if you aren't sure or if it's your first light***
Accessories for hanging amounted to an "S" hook(it fits :)). Something in me felt disappointed by that.
I believe item showed up in mfg packaging - if that matters to you. I also received a white "GH" unit even though I was expecting black, not an issue for me and didn't spend anytime trying to figure out how. If this matters to you maybe email or call ledgrowlightsdepot upon ordering.
