So am I better off buying a panel dedicated to veg and then another panel dedicated to flowering? I was thinking of going with the Magnum and then having the convenience of just switching from veg to flower, but now I am doubting that route.

I'm running a multi stage system so I have a light that is constantly in use for veg. For me it makes sense to have a light with a spectrum tailored just for veg. If I was not running a perpetual harvest I'd have no problem using the flowering LED's for veg as the plants certainly veg very well under them. The ones that do have the selectability are nice as you can turn off the red spectrum and leave them in blue mode to promote more side branching if you are trying to get them to fill out. It is certainly not a major concern though.

I have hydroponics hut lights... pro grow 260

I had the pro grow 550 and a whole row of LEDs went out... and not the whole light

Not sure how each manufacturer wires their LEDs but I would put money almost all are the same/similar and same thing would happen... you would just lose that individual row of LEDs

ISIS and Magnum are wired so just the individual LED goes out and Spectra advertise on their site that they are wired that way also.

im not no fucking spammer i wanna know what you think of this light if i should buy it or not its cut and copy from site wtf are you dumb

uhhhh how much$

Dude! You post like two pages of info and your question gets lost at the bottom. The only reason I didn't think you were a spammer was number of posts but other than that sure as hell looked like it....

....anyway.

At first glance sounds great. 150 3w LED's so actual draw probably about 230-250 watts for $489. Yee haw!

First major issue is if its a US based company or ANY competent company advertising in English......why can't they spell!!!!

Second HUGE issues 120 DEGREE LENS ANGLE. More output is going sideways than down. Will have absolutely NO fucking penetration. You will have to wrap the grow area in Mylar to get refractive penetration and there's huge loss on that.

Next.......

Oh man I didn't even notice the lens angle, I was actually considering this light for a moment! Yeah 120 is absolutely totally freaking lame, unless you like growing lettuce or the kind of grass growing on most peoples lawns. I wouldn't go with anything besides 60 or 90 (even 60 seems kinda high to me, but GLH says they found cannabis grew best with LED with around 90degree lens). Also since the light clearly won't run at 450 and probably more about half that, there is no way in hell it will grow as well as 1000w HID, maybe a 400wHID at best

I think 60 and 90 are the only two usable angles. 60 for taller plants and 90 for scrog style or something that is more area and less penetration. You could definatley hang a 90 degree LED panel over taller plants and use mylar to concentrate the effort but you lose a good chunk of output any time you reflect or refract the light so it would be a slightly less efficient way of doing things. On the counter point a 60 degree panel can always be hung higher to increase the coverage area for scrog grows and would suffer some minor atmospheric loss because of the distance but not as bad as loss due to reflection.

Nice find, here's a different one from same site:
http://www.ledstores.net/apps/webstore/products/show/1887177
There is one with 5 bands, including a far-red, which might touch nicely with figure 4 from the link a couple pages back. The coverage note at the bottom is funny (for the initial height and coverage listed) and informative. Love the prices on that site, and with triple warranty (which means little), and if the chips are all 3W Cree/BL sweet. Spelling is better on that link, but still suspicious, like their reviews/reviewers. "trust this company" -- lol! Either way not bad, Gotham had some shadiness to them as well. Given the price its probably one of their offshoots, heh.

The 120 degree angle on those will cause faster blending of light and should be good for scrog. On the Blackstar, they have a mix of 120/90/60 according to Shawn (which is where the blending info came from), and I think you can sort of see this as some shine as distinct colors at distance , which seems as though they haven't blended well, so I assume these are the 60. Because of this, I think it might be best suited to have all chips in panels the same angle so as to mix all evenly. Does it make sense that a 120 would have twice the coverage while the 60 would have twice the strength at any given height, comparatively? ( of course 60 goes deeper, like divers)

Because area has an exponential relationship to radius a 120 degree lens would result in 9 times the coverage area and 1/9th the intensity of a 60 degree. 90 degree will result in 3 times the coverage and 1/3 the intensity of a 60 degree lens angle.

That's why I don't get the mixing of lens angles in the same panel especially as far apart as 60 and 120. What's the point. They don't compliment each other at all.

 

[meharmon]

I can't recall if I brought this up back when either, but has anyone seen the SolarOasis Grow-bar or grobar thing? looks nice but the cost is crazy.
Here's a link with a comment post (3rd down, Burton Rosenburger) that puts out some nice reading material regarding these, especially from a site called candlepower.us: http://aquaponicscommunity.com/group/artificiallighting/forum/topics/led-ligths-not-for-growing?xg_source=activity

I bring it up because they have a patent on the design of LED which shows the spectrum used, and includes an orange and a far-red which according to one of their charts "induces flowering". Less than 80 watts for $1700, anyone wanna volunteer to test? http://www.groworganic.com/solaroasis-pro-5-ruby-gro-bar-eight-bar-package.html
Or just build your own using their design, ha! check out the abstract for this other model, their first patent that explains the orange is original model. This link has 15 and 30 degree lenses: http://www.google.com/patents?id=S22fAAAAEBAJ&printsec=abstract&zoom=4#v=onepage&q&f=false

Ah, that makes sense, thanks! Agreed on the mixing, again just based on observation of BS240. A purple dot is better than a blue dot.
Here's a new video of a ~50W shootoff in progress, peppers: http://urbanhydro.org/2011/02/50w-penetrator-vs-glow-panel-45-start/

 

[littleshroomie]

But remember it isn;t 500w, probably about 250w really. Yeah I really think the 2 best options are blackstar and spectra, blackstar for the smaller grows and spectra for those that can afford it. Could I trouble you for a link to that 500w Blackstar? I might be interested in getting one as way to save some money because I could get by with a light half as powerful as my 395w. It could be a better deal...

well aware it might be around 50-60% claimed wattage.
however I read that the 500W is brighter than the other models so, could be rated higher (just me speculating)
http://cgi.ebay.com/New-500w-Blackstar-LED-Grow-light-3w-Flowering-LEDs-/290544137393?pt=LH_DefaultDomain_0&hash=item43a5c7b4b1 500W
http://cgi.ebay.com/New-600w-Lighthouse-Blackstar-LED-Grow-light-2w-LEDs-/270718318830?pt=LH_DefaultDomain_0&hash=item3f0811b8ee 600W
lets say its half, 500W(250W) going for 550$, 600W (might be higher, but still lets say half 300W) 630$

spectra 180W is 500$, 290W is 700$.

with blackstar you can get more panels, getting more coverage for the money running.

and as dunit mentioned, gravy is doing a grow with the "240" panel vs spectra 240W. for the big (for me) money difference, it aint that huge gap between the plants.
spectra is about double the output of blackstar so, really keeping an eye on that grow

although , "Originally Posted by supergravy http://forum.bubbleponics.com/forum/showthread.php?p=77025#post77025 Well, it appears this journal is a ------ exclusive now. I was just removed from the other forum, as was my grow journal. I had just done an update today and was keeping my nose extra clean. Really classy of them.

Oh well, I can truly say my experience here on this forum has been much better anyway."

 

[Cereall]

Might not be huge difference in plants now,

But that spectra should be able to grow double the space even though the comparison is only a few plants.
I'm site that spectra would be growing all of the plants under those test lights while I have a hard time believing the blackstar could do that

Blackstar seems great for the money and people gripe great meds with them do I'm not knocking therm... Just saying not a huge price difference when you consider you would need 2 to fill coverage area of the spectra which is obviously quote a bit more money

 

[ledgrowing]

so 120deg angle is no good where does it say the blackstar is not 120?

 

[littleshroomie]

2x blackstar 240W (around 120-150W) goes for around 540$, which is 40more than one spectra 180W, so more coverage, slightly more or similar wattage.
one thing I do like about spectra is great warranty and has proven grows.

still waiting for the result of gravy and other blackstar users.

no one is using stealth grow LEDs eh??

uhh if you look at the grow i did there was penty of penetration with 120 degree diodes growth so thick even using 1w diodes airfow got restricted and mold started growing aint use no mylar either and almost hit a gram per watt tho if that old ecogroled panel i returned was pulling maybe 45-60w then i popped way over my gram per watt desire since i dropped 86g from a single plant no mylar no co2 no nada but plain jane gh nutes

 

[kush groove]

kush you're pretty bandwagon for a dude whos only flowered with the Blackstar for the last 3 weeks of a grow. I only point it out because you ironically commented on someone else falling for a sales pitch. You and gravy are the sole hopes for the Blackstars vs ISIS, Spectra, and Magnum though so keep up the good growing. Ive been following your LED only, bummer about the little setback but better now than 4 weeks in right?

im not riding the bandwagon im driving it...............i just see no purpose in paying two to three times as much for something that is equivalent............and led's are not rocket science.........the real scientist have already laid out what spectrums are required for plant growth.............if u guys havent noticed all the led panels are working fine except for the super crappy ones on ebay.............and oh yeah i wear vans because there never over 50 bucks

p.s. blackstar, isis, magnum and the other led's all come from china...........we are just purchasing from the middlemen
