Sun Systems LEC 315 - Reviews?

How many 315's in veg and how many in flower? I'm guessing one in veg 4x5, and two in flower 4x8?
I have separate veg areas and use blurple panels for veg. In flower I was running 2x Sun Systems 315's side by side covering up to 3.5 x 7' for quite a while. Running multiple 315's gives them a little more coverage, like 3.5 x 3.5'.

Running a single 3x4' with the Tasty LED's 3x 100w T2-1400's right now and just received 2x newer T3-1400's that run 3 COBs at 50w each to fill the remaining space. 600w should cover the room well, grabbed another 3x3 tent for veg to feed it :)

Like my 315's but going to get cob real soon. Two different setups require different lights to get them dialed in. Who knew there could be so much difference?
 
That guy is a pathetic grower, I could harvest everything he harvested under 1 gavita and he used like 10 lights, just look how shitty those plants look super small and spindly, I wouldn't bother even paying attention to those noobs until they learn to grow.
Agreed it doesn't look very good. The only thing I took from the videos was the difference in terps and thc. As long as it's the same guy growing in the same conditions be it good or bad it is a fair comparison. I was curious what the difference between the two would be I never watched the whole thing just skimmed through.

Have you phased out the 315's in favor of the Tasty LED modules? Notice any differences in growth, yield, quality?
Not sure if you were asking me, in my case I'll be using both but favouring the COBs right now due to the terps and weather conditions, easier to keep the temps in check during fall/spring using the COBs. I'm good summer and winter and will likely use a combo through the middle of winter as the COBs may not provide enough heat for me in my setup.

yeah and you can't tell from a video, his shit might be great despite the looks of it.

That's interesting. With the cobs you are dropping your total wattage a little, but a lot less heat? Is it a lot brighter in there now, compared to the LEC's? Do you notice big differences in plant growth and shape, or time to maturation?

Not a huge difference but 2-3F per 315 which during the period in between seasons is a huge difference for me. I mentioned a few things in my thread while comparing the COB runs vs. CMH. One very noticeable observation is when running the CMH the plants pray almost straight up, under the COBs the leaves are more flat/straight out (not that it made much difference just an observation). They also mature slower to get the first buds and that seems to hold true throughout the cycle, adding somewhere between 4-7 days per cycle under the COBs vs. under CMH. The 315's are also pretty intense directly under them so I noticed that the top layer of leaves don't bleach where under the CMH unless I'm running them higher than 20" I'll see some bleaching. When I was running the CMH on one side and COBs on the other, the light coming off the CMH actually looks brighter but that's to our eyes. Likely more due to the spectrum being 3100k vs. 3500k for the COBs than anything else.

valuable perspective, I'll check out your thread. btw you said you added some new T3-1400's, do you mean T3-2100's?

Yeah the models are kind of confusing meant to mention that to @Rahz. The newest T2-1400's should be called T3-1400's. First T2-1400's I bought were 2x 3590's driven at 1400ma, total 100w per bar. These one's are 3x 3590's driven at 1400ma, total 150w per bar.

it makes sense when you know the nomenclature, but my initial assumption was that t2 and t3 were different revisions, mainly cuz there were no t3-1400 on the website

The T2 is an 18" lamp and T3 is a 30" lamp. Originally there was a T3-1400 30" lamp but I restricted the product line to the 2100 series and ended up bringing back the T3-1400 in a smaller package to be a 2x2 high output option and renamed it the T2-1400. There was a 100w T2-1400 when the business first started. :) It is a bit confusing but things will go back to making more sense after the next product revision since there will only be 1 series of 4 lamps.

In the future the standard T2 will have 3 emitters, T3 will have 4 emitters and the T4 will have 6.

T1-V196: 12" Vero based, 196 PPF
T2-V362: 18" " 362 PPF
T3-V483: 30" " 483 PPF
T4-V725: 36" " 725 PPF

The PPF, being the actual amount of light being emitted, seems like the best adjunct to the model indicator. If Cree get's their stuff together there could be T1-Cs etc. but I think after the next revision there will be no need to run two different series at the same time.

Or, I will give them names, Tasty Junior, Tasty Mini Monster, Tasty Illuminator, and Tasty Extreminator Pro... to avoid confusion :)

Yeah all the T series naming is consistent in the 2100 line, this one's an odd ball. I'm liking the 1.4A divers, little heat, lots of photons :)

Now you just need to make a light that can cover a non-tent grow. Need something that can cover a whole lot more than those offer.

btw what is the scoop with Cree? When are they going to give us moar, better, cheaper... ie when's the new models on the street yo whatwhat
 
Sorry one more question for you guys. I'm about to pull the trigger on 3 sun system lec 315 units but at grower house they have the built in ballast one for $485 or something and they sell the remote reflector for $118 and the sun system galaxy 120v ballast for use with it for $175 and I'd need need a bulb for $75 which works out quite quite a bit cheaper but i noticed the remote reflector is quite a bit different then the original one with with the built in ballast. Less mirror like. Does any one have any opinions on the remote reflector? Does the built in ballast reflector use a Phillips ballast or the same sun system galaxy 315w ballast? Thanks to anyone that can help.

I would watch all those embedded videos to try and sort it out. Seems like the Galaxy would brag if they had the Phillips electronics.

I was under the impression that you need the Phillips ballast to use the Philips Mastercolor CDM-TP Elite Agro bulb at its top efficiency, but that might not be the case.

Put my ss315 on a light rail to see if it would cover a 24"x 48" scrog screen with 3 plants, and still get good results. This is a week after flipping it to 12/12... 39+ watts a square foot.... My previous pics show the light on a 24"x 30" screen, no light mover.... Be back with another pic in 4-5 weeks...

but can anyone confirm the ceramic science is a square wave? phantom def. is.
There's. A pdf on growers house for it. There's a phone number to contact them at the bottom of the pdf. The ballast is UL listed. I'd imagine it is square wave otherwise they wouldn't have been able to get a UL cert. Getting UL approved is a very lengthy and very expensive process.


I almost have a feeling growers house owns all or owns part of prism lighting science
What does the crowd think about ceramic science ballast and conversion kit?

http://growershouse.com/ceramic-science-315w-cmh-light-conversion-kit
To answer all of your questions, yes, the Prism Lighting Science 315w CMH ballast is a square wave, low frequency ballast optimized to run with the Philips 315w CDM lamp. Since Philips 315w CDM lamps are an industry standard, the ballast was specifically designed to make sure compatibility perfectly matches the Philips lamp bulb specifications.

And a thank you for pointing out that our product pages did not have that information. We have since updated it :)
