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:
Negative:
Viparspectra 300w
Positive:
Negative:
-------------------
Mars Hydro 300w
Positive
Negative
-------------------
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)

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
