I bought meizhi reflector series, same price range as the others you mentioned and so far I like it for what I paid

I've been digging around a ton for different lights this last week and trying to formulate an idea on which is best. Maybe you all can help fill in some blanks or correct things? This is via extensive digging for each on amazon reviews, amazon question answering, forum wandering, and reddit. Some could be wrong.

Disclaimer: I know, cobs cobs cobs, but some of us aren't really willing to dump 500 into a grow for just some personal pot

Here's what I've come up with so far, just comparing 300w:

------------------
Roleandro 300w

Positive:

• High red spectrum = Good for flower
• White light instead of blurple
  
• $70 on Amazon
  
• Galaxy Hydro is the creator, and they are pretty well known
• 2 Year warranty (Middle)
• Company seems desperate to get them out there as the new kid on the block, so great customer service often reported

Negative:

• Runs hot
• Low blue light for veg
• The 2nd gen 300w lights themselves are still pretty unreviewed and new.
  
• 124w actual power
• No daisy chain for multiple lights

-------------------
Viparspectra 300w

Positive:

• High blue for veg
• Daisy chain ability in 300w model
• A lot seem to consider them to be the most reliable right now
• 3 Year Warranty (BEST)
  
• Reflector
• Runs cooler than the others
• Infared LED's are apparently a good thing, can't find much non conflicting info on this

Negative:

• Low on red light for flower
• 136w actual power
• At $90, they are by far the most expensive 300w light.

-------------------
Mars Hydro 300w

Positive

• Relatively equal blue and red spectrum
  
• TONS have been bought thanks to 2packs on eBay and cheap prices, so lots of success stories
• New generation uses 5w leds, bringing it up to par with the other two
• Lots of videos / guides to converting them to a Cob setup when they inevitably die
  
• 2 pack on eBay for $140 matching roleandro

Negative

• Runs hot
  
• I haven't yet seen anyone say a bulb or 8 didn't burn out/die relatively quickly
• 1 year warranty (WORST)
  
• 135w actual power

-------------------
Each company offers these lights in a 600w variant (~240 actual w average)

They, of course, have completely different lights too that are worth noting. Anyone know much about these?

Vipaspectra's 450w (I've seen a ton of positive coverage on this one as a single light for a 3x3 grow)
MARS Hydro Reflector96 (Another I've heard great things on, but it's older)
Roleandro's COB 400w ($99, but they are the cheapest possible COBS. Still, good for electricity bill and $10 more than viparspectra for it?)
Roleandro's CREE Cob 400w (I'm guessing better than the other, but also more pricey at $179)

Newer T5s good choice.

Samsung QB board kit that is easy to connect up for $149 for flower. See the thread under LED lighting. Stephen's company sells the kit. Our friend with the weird golden death mask avatar is kicking ass using just one to flower.

Wal Mart T8 fixture $10.97 2 bulb set up. 2 Bulbs 6500 K $8. You may need two of those for veg. Total cost for veg about $40.

Total cost about $210.

viparspectra. the others use 3w diodes. vipar uses 5w.

a 600w with 3w diodes will have less growth potential than a 300w with 5w diodes.

this is the exact reason why COB are so good. a pair of 50w COB will grow better than any of the 300w-600w china lights.


i actually dont know this as fact and cant pull references without doing back research which i will not do for free. but i will suggest researching it for yourself.
i have read this multiple places and it is one of the main reasons as i understand that COB is so sought after and effective.


i own the 600w viparspectra
