And yes I have researched COB (chip on board) LED lights and they are def not the way the top LED makers are going. EXAMPLE: Area 51's new LED will feature REAL CREE LED chips , just like blackstars new ion 8 series featuring REAL CREE LED chips, I also see ALL DIY LIGHTS USING CREE CHIPS. Why go with crap COB tech when EVERYONE uses the bigger, better, more efficient CREE diodes? Sounds like just throwing money in a trash can to me. 3 year warranty? Hodge Podge this just is smoke blown right up your ass.

A lot of us DIY are going with quality COBS (either Cree CXAs (like the cxa3070), or Bridgelux Vero).

This is the main problem with LEDs people buy the wrong ones, then they think LEDs are shit because some guy on a forum told him to buy some Chinese crap LED and now you have some HID fanboy that comes on our LED forums and starts shit. Lets inform people trying to buy LEDs to buy the right ones and not Chinese junk off ebay....

some LEDs don't like being left ON continually. I did that to mine and fried some of the LEDs.
..had to replace the LEDs, burned out the whites and IRs first, followed by UV. Red and Blue seem a little tougher.

the funny thing is the American Made LED growlights are filled with parts Made In China, including the LEDs. Ironic?
my "Chinese piece of trash" has 3w Cree LEDs, if you are saying these are trash? ..lol.. because most LED grow lights use 3w Cree chips.
have you ever opened a $1200 LED light and see where they get their LEDs?

You need to chill out man. You seem to be getting ahead of yourself lately.
1)Pet flora knows plenty about led...his suggestion(that I don't agree with it) is a little off his normal path....but the man is educated in LED's and has been around since the beginning. Learn some respect.
2)Blacksatr is the last company to be quoting using real crees...even if they are cree(I personally doubt that) what bin?? And they are still out claiming their actual wattage by a fuck ton.
3) When a light is too close and causes whiting or discoloration in a bad way that is BLEACHING...not hash tips. Hash tips are good symptom of optimal conditions and lighting where peak resin/oil production occurs. It happens only towards the end of flower like leaves fade. Hash tips are impossible during veg just FYI.
Bleaching is from either too saturated spectrum or too intensity. Either way it is a negative and is stressing the plant. Completely different than hash tips.

Fuck ya I opened it up...real grade "A" nichia 219b's
The major part about things being american made that really comes into effect is the actual build and assembly. Parts should come from where the best are...no matter where that is.
There is a difference in chip performance for sure too but it's a lower performing chip will still grow something if it works...an out circuit or internal problem gets you nothing.
Many of the best parts in the industry are not american...but it is the quality and precision that true american builders put into their lights that sets them so far apart. I chinese factory could get all the real top components and still have major issues with failures...because it is their cheap and unskilled workman ship that fucks things up.
The best drivers are from tiawan...why wouldn't you use the best???
Do you think apache could't use/afford crees...cree tries to get AT to down grade to thm all the time. Nichia is there pick because it is superior, so that is what AT uses. When the cree guy says "our XT-E is the closest(not better) thing to what your implementing now" you know your on the right track whether american or not.
Source it all directly form the manufacturers and use the american brains and business to put it all together and make a quality light.
So are you saying that all 3x chips are the same...hit the books bro and learn something. A watt from one company is not the same as a w from a different. I have units with all 1w chips that will blow the pants off nearly any 3-5w maker still today.

While I don't disagree that there's a lot of garbage chinese knock-off's out there. I don't agree with your blanket put down of anything chinese being garbage. Look around and everything you own probably has something made or assembled in china, get over it. There are some that can be had for much lower pricing and perform just fine for someone growing in a small area for personal use or hobby. Not everyone needs or can afford the $500 - $2,0000 top tier lights but may have very good reasons to want to utilize the benefits of LED's. Recommending the big brands is easy, not very helpful though for those on a budget or wanting to get their feet wet with indoor or LED's. Nor will everyone want to go through the hassle or have the skills to build one (DIY). Put another way, not can everyone afford to drive a Benz C65 AMG, that's why they make north american cars, so the rest can drive something and still get from A-->B (that's a jab btw, I'm sure there are perfectly good north american cars, I'd just never drive one)

What lights would you guys recommend to effectively flower a 4ft x 8ft tray if I only wanted to use two lights?

Wow, this thread has gone off the tracks. The OP asked how much distance from light to plant, in case anyone remembers. I made the mistake of running our A51 XGS too close to our two young plants. Moved it out to one foot (still on the lowest 65W setting) and they seem happier.
It's very easy to succumb to the temptation to shove the light right in the plants' faces. Don't do it.

You going to want something that pulls around 600 true watts.
Apache at600 is my choice. I love mine. Some other lights like CLW880 or blackdog 750u come to mind as big units.

How many inches away from the canopy do you keep your AT600?

This thread makes me laugh at some individuals ignorance.. hahaha
.I personally only grow with ebay chinese led's and they have proven to surpass my expectations.. There is crap in anything you buy but just because you have a personal negative view of chinese industry doesn't mean you should express it unless you can prove it. Go buy one on ebay use it fail then talk. But you won't do that cause your mind is made up.. thats okay personal preference i guess just cut the propaganda.
To make my opinion valid here is an image of a plant i harvested using only "ONE" 180W LED CHINESE FACTORY LED OFF EBAY. Its not flawless but if chinese leds were as bad as you say this 180w 90 actual could produce these results.
To me I think its not a bad Idea to use Chinese led's. As a beginner to led's having a cheap option to begin experimentation seems justified. When a novice gets into a hobby does he have the same equipment as a professional no he learns the ropes masters his skills and as he progresses so does his equipment. One day i might order one of those Ferrari type lights but as of now my Toyota Corolla gets me from point A to point B comfortably lol!
