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.
LED grow light depot is everything you would come expect when purchasing a light ! The SK402 came in perfect working order with everything you need was just flipped to 12/12 and we will see what spectrum king has to offer so far so good
I was using a black dog 600 phytomax for my last 3 grows. I honestly was disappointed with the results. Maybe I was using it wrong because I love my 400 watt phytomax. I put this unit over my plants and this is not a joke I am seeing almost double of flower production in my lemon Kush stain. I ordered this 602 unit and it arrived as I expected with no delays and in perfect working order. I would recommend this unit over my 600 watt pytomax actually have one I used for less than a year for sale.
So far wk1-3 outstanding .My light is almost halfway on the dimmer.
