He said this about them a while ago.

Glad the light is working out for you.

The updated version advantages, there's a 13% increase in power draw, and a 35% increase in light intensity. Coverage will increase a little as well, as you'll need an extra few inches of height between it and plant tops.

The housing case will be identical (though I will be changing the color of it eventually, thinking of a brushed aluminum graphite finish), the circuit boards are identical. Upgrading from the 2013 SGS to the 2014 SGS will just be a matter of swapping out the circuit boards with the new LEDs, and swapping a 550mA driver for a 750mA driver (that part is optional). For those that want to upgrade, it'll be fairly inexpensive, compared to buying a whole new panel.

The expandable lights will be fairly costly for just 1 unit, but the prices will decrease as more are purchased. Probably will be about $125 shipped for 1 unit, just because of shipping. But for a set of 16 will be roughly $100 each shipped. These are all just estimations, if I can get the price down some, I will.

and I am pretty sure they are xt-e 4500k. He said his tester was getting amazing results(flower). The WW is taking over. First a little now whole panels. The other multi unit system is what I am waiting to see come out.

Sorry peeps but I don't feel like reading this entire thread. I'm very interested in LEDs but they don't seem to have the coverage. Would I need two panels for a 4x4 tent. What do you guys recommend?

 

[RedCarpetMatches]

Seems like 2 Hans panels for 500$ would be the most bang for your buck. Anyone have better advice?

 

[jimjim2609]

Are they designed for flowering???with straight 4500k xpg........... I wouldn't be too concerned about them, now an all cree xte warm white panel would intrigue me.

That's what I'm building atm. I am adding another 10 cool white cree xte's to the 10 warm white cree xte's and adding a mix of 60° and 80° lenses. Its a pity cree don't do a 660nm led, 10 of them wouldn't go astray either!

I spoke to Jeff at area 51 he reins he hasn't had a bad grow at all with the all white sgs 160 they've pulled half a pound+ from under one of these beasts the 24 extra white LEDs add more red in the spectrum and more photons with all the testing that's been carried out on them he hasn't had a disappointing grow yet

Ah it is an all 4500k xt-e panel then.....And he's charging the same price as the xp-g/xp-e 152w panel with better diodes and more wattage??? you sure ?? yes it's all leaning towards high lumen per watt WW leds being the future...........copying HPS, go figure

Yes best bang for the money especially the latest version with 660nm osram........4x2 FLOWERING coverage with quality emitters for 500 shipped is still hard to beat IMO.

Their is no reason to use cool white leds, when ww have enough blue too keep it manageable(without any 730nm) IMO. I ran the hans panel full blast from seed and they grew nice and bushy with only 4 blue leds out of 28 "reds". We are not growing cannabis for the leaves!lol

good luck with your build Jim

@psuagro what would you recommend for 4x4 coverage? Can I get a link to the latest Hans please or was that the one I was already scoping on his sight. Thnx in advance.

 

[puffenuff]

Area51 site says the new whites are xpg
Power Source 4500k White + Red: 48x Cree XPG Outdoor White + 24x Cree XPE Red
Power Source 4500k: 72x Cree XPG

How much are you willing to spend?? 4x4 flowering coverage with leds gets very expensive. 4 hans panels @ $1000 will do but you must keep the girls short due to the wide led lens angles. His latest panel is the one on his website with the two white leds. to see what 4 panels can do look here http://www.ledgrow.eu/Reviews.html first review looks like amazing results from 260w(hans math excludes the driver).....

But there are other options for more $$$

Area51 site says the new whites are xpg
Power Source 4500k White + Red: 48x Cree XPG Outdoor White + 24x Cree XPE Red
Power Source 4500k: 72x Cree XPG

ah make sense now^^^^^ that they are the same pricing......good catch puff!

 

[Shwagbag]

Those Area51 lights look pretty decent.....

 

[RedCarpetMatches]

Let's see...4 Hans or 2 area 51s. Man I'm on the fence here. Wouldn't I also have to get a heater to raise ambient temps? I know they'd be great in the summer.

I guess it depends on your climate. My boxes are perfect in the winter (Michigan). I have to run AC in the summer. Plug'em and run'em, if you're between 70-80 during daytime and above 50 at night I wouldn't worry. You could adjust your light cycle from 24/0 or 18/6 depending on temps as well.

Keep us posted!

 

[PSUAGRO.]

Yeah what shwag said^^and you also have the option of running autos under a 20/4 light schedule, keeping those temps up for most of the day. See autos do have there place for something lol

 

[RedCarpetMatches]

I'm just trying to think cost effective in the long run. I'm trying CFLs for veg and they are blowing me away. Just hate the efficiency and design of the things. Feels like I'm wasting half the light even if I'm close. LEDs are perfect spectrum, cheap to run, and stealthy. 18/6 is what I run for veg so that wouldn't cost shit with LEDs. I have so many CMHs so think I'll maybe just veg with LEDs and flower with CMH to keep cost down. Thanks for input guys. I'll be ordering LEDs within a month. Just have to decide which ones first.

Hey shwagbag how many squats do you do a day?!

EH was the first person to like my post...not like that is like law, but I thought it meant I was pretty correct. And he said they were to be xt-e's on a few occasions in the past, but things can always change obviously.

xt-e's were designed to replace the xp's with 2x the power for the same price simple as that. The xt-e is probably the most economical chip we(normal people) have access to and it is also one of the best. #1 in WW and #2 in CW imo. So I would actually be a little confused if the price went up. very much.
A quote rom the xt-e page from cree...
"Cree XLamp XT-E White LEDs are the highest-performance white LEDs available. The XT-E LED delivers twice the lumens-per-dollar of previously available LEDs in the popular XP footprint. By leveraging the popular XP footprint, customers can easily incorporate the XT-E LED into existing XP LED designs to shorten design cycle and improve time to market. - See more at: http://www.cree.com/led-components-and-modules/products/xlamp/discrete-directional/xlamp-xte-white#sthash.nlev4tDz.dpuf"

The xt-e has much better thermal performance and higher output. Plus it's spectrum is tighter and slightly better fitted to the plant response curve than the xp-g. All in all the xt-e seems like the better choice imo, and would get me to buy a panel. But the xp-g's obviously work great, just look at dawg, DJ, puff, and about 5 others on here. So EH knows what's up and what works and is going to deliver a panel that will no doubt perform.

 

[Edstonx]

Wow nice wall of info in just a days time. Usually this thread moves slower, I'm always following it because someone is bound to ask a question that I can use the answer to.

Well thankyou everyone who supplied that information. I now am pretty confident that I want to upgrade the light I have, now the only debate I have is if I want 2 more or 5 more of the new 4500k SGS model, or maybe wait for the expandable models that I didn't know about till now.

I must admit until now I didn't know much about XTE vs XPG but I also don't think it's all that important in this case. I've seen enough threads on here with people flowering under Cree bulbs to know that it works. And now based on what I've read here I'm willing to confidently wager that yes this light could pull potentially better yields. With that said if anyone has more information that would prove my assumptions wrong I'd find that incredibly helpful.

Now I will go back to lurking through these threads.

All this info makes me itchy....but I am broke. :0)

Thanks for taking the time.

Are there any new models coming out before I take the leap on area or Hans?

 

[multipass]

Its getting better and cheaper all the time, and at a pretty fast rate.. but I would still say it is a good investment if you got either of those.
