Yo Guys
has anyone ever bought LED grow lights from Ali Express or any of those fong kong places?
are they legit when it comes to true wattage and full spectrum? 
REALLY wanna move to LED"s
 
Stay away from that. Get yourself a 400w HPS setup to start off

Go Alibaba route, either R2T or Meiju. Good quality quantum board clones, with legit diodes. I've been running my 4 of their 800 diode boards for close to a year with zero issues. Stay away from companies like NaLite and Ono. The lights look pretty, but the quality is garbage. I just replaced a popped power supply in mine this weekend. Thankfully I had a spare power unit so i have 10 backs ups, but i'll most likely be rebuilding this light and rip out their shit drivers and stick in two mean wells.

I'm personally running the R2T QB288 v2 boards from Alibaba, love them and would happily purchase them again.

 

There are a lot of over-rated LED lights out there, claiming that it is a 600W yet draws far less power from the wall. With the QB's you check the voltage and amps which are being sent to them and therefore you get an accurate and true watt value.

I also suggest you look at growopz.com which is a local guy in cape town as well as atreumlighting.com I bought myself strips from Atreum and I'm very happy. 

 

Atreum has some boards available on amazon too. 

 

All these boards are made in the same place in China.

Thanks @Dr. Green

Yeah if you don't mind a bit of risk, China has some great deals. 

I ordered one from Meijiu to test, because it did seem to be a better deal than my own lights :P

But the sales lady marked the wrong price, and customs stopped it, and charged me R4500 penalty, and it took 4 weeks to get it released, and now it will take 90 days until they reply to my appeal, (and customs has always rejected my appeals).  So there is risk. Customs is a bitch. 
It ended up costing a lot more than advertised, and two of my lights would have been much better deals, in this case. 

But if all goes smoothly, it'll take about 2 weeks, and you can save about R1500 over equivalent local lights by buying direct from China.    

My criticisms with the light, compared to my own lights, is the heatsink temperature, and the footprint hotspot.  After half an hour, my infrared thermometer measured the hottest at 58 degrees C, which is pretty toasty, and the PAR measurements have a big spike in the middle, and trail off quickly.  The datasheet shows that the 30 degree temperature difference reduces efficiency by about 4%, which is fairly substantial.   The longevity probably suffers a bit too, but LEDs are pretty hardy.  If anything, it's like they'll last 13 years instead of 14 years.

I'm not particularly interested in reselling Chinese lights, but I'll see what the local market does.  There's a couple of local competitors offering these 240W Chinese lights at R5999 (one on a stainless steel heatsink?! , and one has no information on theirs).  

Overall conclusion:  Not a bad option.  Bit risky.

      LARGE BIRDWING REFLECTOR ADJUSTABLE
      High quality Adjust-a-wing reflector made from 95% reflective aluminum. The spread of the reflector can be adjusted, narrow and wide settings are possible to adjust the reflector to your grow area. Two sheets of aluminium are gently folded by adjustable wires to change the angle of reflection. To reduce intensity and increase area they can be tightened to decrease the width of the reflector.

      This is how I built an overpowered light worth $2500+ on the market for only $850. All currency is CAD.

      *BEFORE STARTING*
      Watch the 6 part growmau5 series to learn the wiring:
       
      For the grounding plug:
       
      Technical:

      4x Hlg 185H 700ma in series drivers (i suggest you buy the newer 240H model) $250

      40x 5000K $350

      7x 3000K $25
      (You can use less I used way too many)

      All are bridgelux Gen 3/ C3 (Make sure theyre all plug in only dont mess around with the solder ones unless you have 100+hours experience in soldering)
      The 3000k ones I used were soulder onlys. Lost a couple due to human error

      Total Cost (TC): $575

      Frame:
      (Choose a better material for frame, I used wood composite because I was lazy) (I would think aluminum would be the best material but all have their pros and cons)

      Wood composite 2x2ft v

      Matching plastic 2x2ft (painting frame) $50?

      Thermal tape (sized to the width of the led bars) $20

      TC: $70-100

      Electric:

      100’ length 20guage solid core wire $60

      50 pack 2 wire wagos 221 $25

      4x plastic junction boxes 4inch x 4inch x 3inch (make sure it comes with something to plug up the holes and hold the wire)$40

      500 assorted pack heatshrink tubing $20 (good to help fit in junction box)

      4x Leviton 515PV 15Amp 125Volt grounding plug $20

      25’ 16guage wire (for the grounding plug) $20

      TC:$165-Everything is super flexible here just make sure your amps and volt calculations are solid.
      -Dedicated extra fans (required): With 2 medium fans running on the light, and another 2 small fans running on the drivers everything is 20C-25C.

      SETTING UP THE DIMMERS

      (Very easy if you do it like i did in these pictures)

      All you need is:
      •100k potentiometers (maybe an ohm meter if you want to make sure ur dimmers go all the way to 100, most dont they go to like 92 or 97)

      •20 guage wire (same as the led strips)

      •Plastic junction box (make sure its got rubber wire holders that you cut a hole through with scissors and put the wire/ potentiometer through)

      •211 Wago wire connector

      •soldering machine (temperature is dependant on what kind of solder you use) $25

      • silver solder (find a lower temp soldering machine ~360f for silver) $20
      (This light is truly 800w if you use the exact parts, if you use more or less drivers and led strips or different brands then the wattage can vary from 600-1000, materials are very flexible just try to make sure volt/amp calculations are correct) (Always be cautious with electricity, build this whole thing without being plugged in to any wall outlet/power source⚠️⚡️)

      The Nova 420W – 1000mm produces a large amount of light(47248 Lumens), making this light ideal for larger grow operations where the fixture can be placed further away from the canopy. The light spectrum and intensity produced by this fixture are both suitable for the vegetative and flowering stage (inclusive of Far-Red chips) of growth. IP 44 standard.

      These are my DIY QB lights
      I can run them full power with no issues. Quite expensive to build, but I like the reliability of passive cooling.
