I thought they were making the 600s in 6 band now are those a bit older model? seems like they are fuckin destroying

11-15 band is unneccasary its like an hps light and how your plants only use 20% of the spectrum put out same with the 15 band lights. I would say everything in blackstars 7 band is essential since i have seen better results with it than my friends tri band and quad band panels he paid out the ass for.
Well I think a plus about having more is you have a mix of lights that are great for veg, and a mix of lights that are great for flowering. So its like running a MH and an HPS at the same time at all times instead of a light that only has 3-4 lights/colors/peaks/wavelengths. Definitely different operations in cannabis prefer different lights and I'm pretty sure having more than 3 or 4 bands can be of great benefit. But it looks like tri and quads to quite well on their own, so I think its mostly just the pricing.
But don't cannabis plants make great use of more than 3 or 4 peaks in their usable spectrum? There are multiple chlorophyll and other bits that use differen't nm of light, and like you just said a 7 band seems to work better than a 3 or 4 so why couldn't say a 12-15 do even better?*(although I imagine the difference between a 7 and 12 to not be as much as the difference between a 3 or 4 and a 7)

IMO this is my opinion i have not proven it with anything other than the research i have done to convince myself is that those extra spectrums those guys are offering are gimicky Lighthouse even says that the 7 band is not all that much better than their quad bands which is why there are not that many led's of those other spectrums in the panel. Just a few to help supplement just my 2c

You should read what the manufacturers say about different wavelengths. The theories have been put to the test. Concentrating on significantly beneficial bands makes for the best technology, the rest is wasted space.
I got this from an independent LED light builder in England, the guy knows his stuff:
You need 5 different leds to get plant growth equal to a standard metal halide/HPS light. As well a standard red and blue (640 Nm and 460 Nm) you need 660 Nm red to promote flowering, 430 Nm blue for the hard resinous buds (without it you get 'fluffy' buds with no weight) and warm white which provides far red out to about 800 Nm, again for flowering.

was just browsing around ebay.... i understand these are probally ~20w each panel but any opinions on it?

This might interest you, it it also from the man I quoted above regarding his light:
Please Note! Anyone else would rate this as a 108 Watt light!
They would rate it as 108 watts by multiplying the number of leds (36) by their power rating. This is the way all the other leds lights on Ebay (or anywhere else) are rated. I do not do this as it is dishonest. As leds (unlike other types of lighting) require a constant and exact CURRENT (not voltage) in order to make it possible for manufacturers to make standard power supplies it was decided to classify power or lighting class leds as 1 or 3 watts depending on whether they required 350 or 700 mA. No power led actually draws exactly its rated wattage as each color requires a different voltage to achieve its rated CURRENT. As leds have become more efficient, the voltage requirements have dropped so the actual wattage consumed has also dropped even though they are still called 1 or 3 watt leds and are now far brighter than a few years ago. Confusing I know! I rate my lights by the power they consume, not by the number of leds as I consider it more honest.

Those are some of the lights that give led's a bad. If u read the specs it actually says 0.2watt per bulb. Save your cash and find a better light. I have been using a Blackstar 240watt for over 2 weeks now and my girls look amazing. Its almost harvest time and I am currently flushing, check out my signature....

Sorry for the confusion, that quote was regarding a light built by an independent manufacturer in England. He understands LEDs and his info is insightful. I just passed that bit along for what it's worth.
Regarding your panel, I'd avoid. It might work, but there is no beam angle info...and it looks like the generation of Chinese LED lights that gave LEDs a bad name. But don't take my word for it.
I'd rather use a GrowSpot bulb, if I were going to stay within that price range.

i see what u mean with the 0.2watts per bulb...but alot of the leds on ebay dont say the watts per bulb. i know the blackstar panels are great..but dont have that kind of money at this point in time.
no worries...grow spot bulbs as in this? http://cgi.ebay.com/TRIBAND-LED-SPOT-LIGHT-GROW-hydroponic-UFO-FLOOD-USA-/400184303029?pt=LH_DefaultDomain_0&hash=item5d2cd7ddb5
im lookin for the watts per bulb and cannont find it on alot of led's on ebay...any suggestions?

Good, thanks for asking. After a setback from a hot dose of organic nutes I received as a sample, things are back on track and buds are swelling.
I'm just shy of 2 months in, I figure I'm 10 days away from harvest.
(I was just over at another site and I saw this Onyx on day 42, grown under 90w led.)

Tried to find the ebay seller that sold that light but couldn't find it but I found this: http://arcticsunled.com/
also a grow journal, https://www.rollitup.org/grow-journals/395828-platinum-pre98-bubba-purple-kush.html
Looks like GLH 2011,

Well a good sign by looking at 626w photos is that the panel actually uses a HEATSINK compared to blackstars with just a flat piece of metal.
