so you think the califonia ss880 is no goodHas anyone independently confirmed those PAR readings?
Based on the BS which permeates the LED market (HydroGrowLED claiming to use Osrams when they don't, California Lightworks's "adjusted PAR", and SpectrumKing calling COBs a "myth"), and Platinum's demonstrated willingness to hijack a reputable company's reputation.... it seems reasonable to be suspicious of epi-whatever diodes outperforming COBs.
That doesn't necessarily prove epi-whatever diodes outperform COB. Not to be insensitive, but it sounds like the special olympics. Sketchy, name-ripoff Platinum won. You have a lot to be proud of.
My impression was that it's an overpriced epi-whatever light primarily because they didn't say what diodes they use. I.e., if the diodes were something to brag about, I'm sure they would have bragged about it (considering the way they fabricated some PAR numbers, and they're pretty heavily marketing oriented). But, unlike the other high-markup epi-whatever fixtures, they did put some creativity into their case (at least). I.e., it's not a direct rebrand of an epi-whatever light.
However, I thought I read a few months ago that they CLW began using Osram diodes in their new lights. That kind of proves the point that they would have mentioned the diodes in the past (if they were anything worth mentioning).
$2,100 for 650w seems pretty steep considering the alternatives. Over $3 per watt when more efficient COBs are available for $2 (with longer warranty). For that kind of money, a 2-year warranty sounds like a disposable light.

yeah i got there new one with the osram diodes .but i dont know much about all these names there like another language to me..what kind of light do you use...
I know. It's a big learning curve -- and a great deal of predatory sellers. I use Area51 for larger space. Cree lightbulbs for a small space.
Your CLW should work well. I think you said you had some T5HO to supplement with if you find it's insufficient in mid/late flower.

In my opinion, Bella, the lights will work and grow just fine. You'll have a better spectrum than HPS, but that's where the advantages end. You're not getting much efficiency relief, and you're paying out the ass for it, meaning your ROI is over two years out.

yea i got 4ft 6 tube from argobright also ..which was thinking of using towards end if the t8's don't cut it ..you have a link for area51 heard few people say stuff about them and i found one site but it said it was sold ou

You're not in a hurry to buy, are you? Tasty, Johnson, Gogreenleds are often recommended by the knowledgeable people here.

no i just bought ss880 like 2 months ago and like 3 weeks ago the t5.but def within next 3-4 months

When I said more power I meant it to mean more PAR, I did`nt expect anyone would think it would mean to waste more power, obviously more intense light is the key to getting a deeper layer of big top bud, but actually a thin layer of bud is more efficient but the most limiting factor most inside grows have is the space of the flowering area, so people try to get more per sq M not the most efficient w per g as most people don`t have the space to SOG with .25w leds it takes up a lot of space to grow using the most efficient lighting methods, so right off the bat most growers are compromising yield per w
Mars Hydro growers tend to think in terms of "adding another light." When you see 90w/sq ft grows (on an autoflower, no less!) and referred to as "results, not rhetoric" it makes me want to define terms.

Hmm auto`s are tricky you have to gauge them as some are so tiny you`ll never get over 7 grams off them no matter what you do
but the bigger ones I normally use around 100w per plant, don`t often see an auto get over 100 grams but some people can get them well over 300 grams, I normally see them using 300w to 600w per plant when getting that kinda yield with autos

I'll never really understand why people still grow ruderalis strains.

There very hardy and sex fast I mean some of them sex 4 days after they pop
Plus if your veg area is kinda big or your running veg for a long time like 16 to 20 hours of light a day and you still want to crop something well run some autos and you`ll get something to toke on by the time your ready to flip the big bitches to flower
Plus outside somewhere with long days autos will still flower in 50 to 120 days where as normal plants may take forever to even show sex

i am in no way a mars fan, but have one i've been using mostly because i can't afford to buy an a51 or even diy my own at this point. however, i am in my 3rd week of flower in a 2x2x6 tent (my plant is approximately 2 feet tall because of scrog) with the old old style mars 100x3 and have a couple questions.Mars Hydro growers tend to think in terms of "adding another light." When you see 90w/sq ft grows (on an autoflower, no less!) and referred to as "results, not rhetoric" it makes me want to define terms.
1 - how far away can i get this piece of shit from her without bleaching her (if bleaching is even possible?) I removed the glass, btw because it kept fogging up and it actually runs cooler without it.
2 - do you recommend any led's for additional lighting to finish out this cycle with a halfway decent yield?
And don't worry, if i use this mars 100x3 again, it will be with the old drivers/fans/heatsink/case running 4 x CXA or CXB3590 or 3070 @ 72(77)v version

I'd say you can hang it within 8" ... if I can run the so called 400W Mars that close in flower then no problem with the 300W you have....
the only problem will be light spread from only 8" won't be very good...
When it comes to upgrade time you may want to research how many cobs will actually run on the drivers from that light, and light spread will be an issue packing 4 cobs into those fixtures isn't worth it in my view, maybe 2 per light.

CLW used ledengin before, now it's osram ssl.............no group/bin #s given though
it was Lumigrow that exaggerated their par #s (lumipar, guod caught it and ruined our parade
) on the pro series back in the day

The scrog isn't completely full and i think spread from that far away may actually work, upon closer inspection i'm only taking up 1.5x1.5.
I've actually checked into it and 4 will work fine as long as i use 72v version. I had a thread where i started out asking opinions and want to document it, but have to wait until this is finished and i can afford the cobs/holders/etc, hence the questions. I will work out the case problems later, and may just end up scrapping the whole thing - but have to give credit to Growmau5 for the idea and Rahz for the help on deciding on proper cobs for the old piece of shit.
California Lightworks played games with theirs too. (They may still. I haven't looked.). In their literature they give PAR as "adjusted PAR" with a footnote explaining how it's been adjusted.
