A lot of us DIY are going with quality COBS (either Cree CXAs (like the cxa3070), or Bridgelux Vero).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.
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.How come never run a LED more than 18-20 hours a day? I don't run mine more than 12 hours a day but just wondering.
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....
Cree Inc. is a multinational manufacturer of semiconductor light-emitting diode (LED) materials and devices, headquartered in Durham, North Carolina. Most of its products are based on Silicon carbide. Cree was formed in 1987 by researchers from North Carolina State University.
In 2005, Cree opened a subsidiary, Cree Asia-Pacific Ltd., in Hong Kong.[SUP][3][/SUP][SUP][4][/SUP]
In March 2007, Cree acquired Cotco Luminant Device Ltd of Hong Kong for $200 million.[SUP][5][/SUP] Cotco is a supplier of high brightness LEDs in China.
In 2009, Cree announced an agreement to purchase a 592,000-square-foot (55,000 m[SUP]2[/SUP]) facility in Huizhou, Guangdong Province, China, Cree’s first chip production facility outside of North America.[SUP][6][/SUP] Also in 2009, Cree announced an expansion at its Durham plant.[SUP][7][/SUP]
On February 8, 2012, Cree announced the XLamp XT-E, which they said delivers twice as much light for the same price as older LEDs.[SUP][8][/SUP]
That light is the biggest waste of 400$ you can find. Just throw your money in the trash that is such a junk Chinese light...no warranty for 400 bucks? lol what a waste this petflora guy is clueless about LEDs
You need to chill out man. You seem to be getting ahead of yourself lately.And yes I have researched COB (chip on board) LED lights and they are def not the way the top LED makers are going.

Fuck ya I opened it up...real grade "A" nichia 219b'sthe 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?
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)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.

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.
You going to want something that pulls around 600 true watts.What lights would you guys recommend to effectively flower a 4ft x 8ft tray if I only wanted to use two lights?
This thread makes me laugh at some individuals ignorance.. hahaha.This guy is suggesting these junk lights in this forum and multiple others. I am trying to help someone make the right choice before buying Chinese junk off ebay with unproven results.
