Need help choosing LED

Mars are for people who don't know any better....or won't review "evidence"..."Green" wavelengths are just as if not more important than just the Blurple wavelenghts and why we see better results with "white" full spectrum light.

Mars weren't even that great when they were introduced almost 6-7 years ago and they haven't changed much, while LED diode tech has changed leaps and bounds? why is that?

The Vero's are 40% + efficient especially that Vero 120 from Optics...The mars is LESS than 20%, about what you would get from a CFL and 200 watts of CFL doesn't cost $300.

I think I'd trust cob LEDs over clustered LEDs easily. Streetlights and industrial flood lamps are the few applications of cobs, without a doubt I'd buy that over LEDs used for flashlights.

Cobs rock huh guys...

Cobs are just basically better clustered LEDs, not dissimilar to the LED modules used in 1/3/5W generic or cheap grow lights, just packaged differently and performs much better. You know, technology actually designed to do what it's supposed to. It's the same with bulbs - you're not going back to incandescents when you know there's CMH/HPS right? That's just counterproductive. Take out the weak link in a design and you eradicate its downsides - clustered LEDs vs cobs. I'm never buying a clustered array of LED modules UNLESS it's a top-end fixture by a respected and transparent manufacturer with LED modules that actually contribute to a plant's growth and health. Again, I don't run my flashlights on AC power.

It's your money, your call. Advice is only good if you heed it.

Need fans for intake, any suggestions? an will the optic do good?

so because i have 3 of the 300's and 2 of the 150's your telling me i dont know any better? thats fucked up. i know what i'm doing, just not spending a shit ton on other fucking led's. you may be a well known memeber here, but the fact that you said people who buy them dont know any better, yeah i dont think so man. i'm more than happy with mine and recommend them to people.

budget, so do you think i can use 2 marshhydro 300w full spect, Just to flower in that cab.. Tryna get things cracking.. Rt

i grew a sativa with just 1 of those and got 5 ounces. i used 2 of them on an auto and it loved it. i'm not totally happy with led and the way they flower though. ive ran it all led, led and hps, hps. i find that the combo is the best for me. but for $130, you can get 2 of those MH led's. not a bad price. definately less heat than an hps for sure

If you can't post what the actual data is for the Mars LED then yeah, going on a generalization, yeah they don't know any better...The argument is tired...Halogen grows too....

Mars again is for people who don't know any better....you can buy a better outputting light for the same cost, spectrum and raw PPF. Show me where I am wrong and I will change my statements.

It was a generalization of all mars customers, grow up, don't take it personally, prove my data wrong or move one, attacking me disrupts from you know, the actual argument.

The advice is good, hope i made the right choice for me..

not all mars customers just "dont know better" god damn man. i cant stand people like you that is just an asshole and ruins shit. worthless

Still haven't changed...thanks for this PM this morning too...

got a real problem dont you. didnt attack you, but the fact that you think you know what the fuck is best is a joke. because YOU dont like it doesnt mean they are garbage. fucking idiot. i was wondering how long it would take for me to find the one asshole on this board...guess i found him. whatever...good luck on your shit. you'll need it

Geez louise who pissed in your cheerios...? huh

I was going to backtrack and explain, but you certainly know it all.....Tell again how the Mars light is producing more PAR and Umol/s than current lights?

I too once, was naive and full of shit....I wanted the Mars for COST purposes...then I realized after learning the #'s, that I could build a far superior DIY light using ACTUAL CREE/Vero LED's.....and it would still cost LESS than the MARS...

Mars $9+ / Par Watt
Cree CXB 3070/3590 never more than $4 / Par Watt


Mars 300 = 20% efficiency @ 170 watts of ACTUAL draw that emits roughly 34 PAR watts [Efficiency x Power dissipated]

while a Cree CXb 3590 @ 56% efficiency @ 100 watt will emits 56 PAR watts!!! [That is with a 58% reduction in Wattage Usage and a 60% increase in umol/s ak PAR watts...]

IT IS ALL ABOUT PHOTON DELIVERY for Growing Cannabis....you can deliver Photons with anything, but if you had a choice and some education....MARS would be left on the shelf

I'd like to add, that marshydro doesn't have the 320-380 UV spectrum. I was going to try one until I seen this. My current LED does have it, and the trichs exploded starting week 3 flower. I know my experience is anecdotal, but god damn, I'm sticking with LED's that have the UV spectrum.

Sorry, but your light would be WAY more expensive if those UV's were actually in the 320-380 range....If you have a datasheet from the LED bin, please share it with us...Otherwise it is the Manufacturer's half truth at best.

Uv's in the that range are still like $50 per watt of Legitimate diodes....I know I am the LED asshole revealing all the truths.....But seriously, read up on it.

Find out what UV actually accomplishes in plants and why growers want it in the 1st place...Then you might decide that it isn't needed either

Go look up Hollandstar. And I can attest that there is UV coming from this light, because as an ex welder, I know wtf arc eye feels like and this bastard gives me scratchy eyes just the same. Also, several diodes appear burnt, but because of the spectrum, you wouldn't see it. Proof enough for me.

They are not those nm's you suggest....they are probably more in the realm of 410-420nm which is just UV-A, a blacklight.....

UV diodes in the 320-380 are hard to produce for any manufacturer, let alone CHEAP LED light companies that only exist to make a buck....

The Good led companies haven't even started playing around with UV photo-biology yet...Because real deal is EXpensive, not Cheap.....and definitely has a datasheet to reveal spectrum characteristics....

You cant physically "see" 320-380 nm with your eyeballs anyways!, they are invisible spectrums...Proof is repeatable data.

I just told you I can't see them, and I already "know" I can't see them. I dabble with lasers and spectrum's. My light hits UVA spectrum's mind you and not the UVB.

320-380 isn't UV-A

We want UV-b though....

Isn't JUST UV-A but is more predominant from my understanding

UV-A takes up about 8% of lights spectrum with UV-B taking up about 0.3 %
Based on the suns output of natural light mind you.
