Hey there, I did something similar recently, ditched my old 1000w HPS in favor of a new LED full spectrum bar light that pulls either 600 or 640w from the wall (I forget which!). What I did was search out the manufacturers that produce the name brand LED bars for the US based middle men, and was able to find several on Alibaba. I ordered directly thru the manufacturer instead of the middle man, the only difference on the light is that it doesn't have their logo on it. The big difference? The price. The exact same lights are selling on Amazon for $600-1000+ all day. Mine is going for right around $1000. I paid $430 including shipping. It shipped to my house from Hong Kong in 3 days, less time than it takes for Amazon to ship some packages from inside my state. Product quality is on point. Blinding. My plants absolutely love it, and the savings on electricity and reduction in heat are a big plus too. Mine has the Samsung LM301B/H chips, and a meanwell driver. These are the more desirable options in these types of lights, as opposed to cheap light chips of lower quality. I love how evenly it distributes light across the entire 4x4' footprint of my tent. It would absolutely cover a 5x5' as well, and is advertised for that size. There was very little assembly involved, simply plug each bar in and you're up and running! It does produce some heat but nothing close to what the HPS put off! My friend runs more than 10 of these chained together, and his finished product is phenomenal. He has done very well on weight with these as well. I just flipped my 1st run under these to flower a few days ago, and so far everything is fantastic. I know there are some stigmas attached to certain sellers on Alibaba, but as long as you choose a reputable one that's been in business multiple years and has positive ratings, you should be in good shape. Also, choose one with multiple seller "badges". This is the avenue I went, and I have no doubt this post will be valuable information for others. I will attach a pic of the light running so you know I'm not just "blowing smoke" hope this points you in a helpful direction. Happy growing!
