Which LED for 4x4 tent

check on aliexpress for a light producer that is called "yxo" and look for the 480w samsung led light (Samsung LM301H 3000k + 660nm). You will not regret it!

Futur vert are killer LED’s . They just started to sell them in the uk is ur instagram I can probably get u a discount code

450 pounds is very close to the Telos 0010 which I use for a 1.25mx1.25mx2m this is my largest tent of 3 and I use it for flowering. It has never done me wrong and the upgraded version with the better panels which is 150 pounds for the panels but you can buy the pro version with them already installed from GN. Have a look at my flower tent and see what you think I'm sure the light is in frame a few times. Fortunately for me I knew the people that own the grow shop personally so I got mine as a show piece so it was considerably cheaper but I could not recommend them enough very low running temp is completely silent and ip 68 water proof too so perfect for pushing your humidity without worrying. Comes with a 10 year warrantee I believe too so that's always good :) Take a look the make is GN and the product is Telos 0010 :) Hope this helps I do use a cheaper light in my veg tent the mars hydro ts1000. Now these flat panel designs are very fragile if you accidently knock it you can damage your light. I think the more robust the better in my personal opinion. I only switched from HPS through the summer and now I find myself using the LED instead of the HPS for cost effectiveness and efficacy along with the environmental control too. its going pretty good :)

If you are going to spend that much money, I'd look away from Spider Farmer and Mars Hydro, and start looking on Alibaba. You can get a Meijiu Lighting or a Geek Light that is 2x as powerful as the spider or mars for about half the price. https://meijiuled.en.alibaba.com/ https://geeklight.en.alibaba.com/
