OK, well go ahead how you like. Before I buy an LED, I want to know how many of each type of LED in what spectrum or I'm not interested. There most definitely is a difference between different wattage LEDs. How many people do you know still buying 1w or 2w LEDs? Are you saying no respectable led maker such as cree would want it listed that their LEDs are the ones used on a light??? Are you saying spectrum doesn't matter?!??!?! (also not listed) You're awful defensive of this company are you sure you're not associated with them?
Dude you're way out of line here. I was the one that wrote the post with the link. It was my first post on this forum and I did it to maybe get an open discussion going. I've responded since with other info that you obviously did not see. I'm sorry I chose to post here. You seem like a douche

Why the fuck would I be associated with them?
When I mention "LED", I mean the electronic component, not the fixture as a whole. Now if you read again, you'll see that I specifically mention that spectrum does matter, as well as light output and power consumption. These 3 things matter because the quantity of light at a specific spectrum is what grows the shit and power consumption is what you pay at the end of the month. What DOESN'T matter is how they (or any other manufacturer of course) get there.

Now an example to illustrate how "the higher the wattage, the better" is not always true:
Cree XP-E Red 801 // 140 lumens at 1.6 watts (700mA * 2.25v)
Ledengin LZ1 R100 // 120 lumens at 2.6 watts (1000mA * 2.6v)
As you can see the Cree has a lower "wattage" but outputs MORE light than the ledengin.

Then again, the fixture we talk about could very well be using shitty chips (I DON'T KNOW) as well as not giving the wavelength. This fixture could very well be garbage because I think a PAR of 183µmol/sec is pretty low and I wouldn't be surprised if it happens to be lower than what a blackstar would output. But it is still valuable info and if other companies could list this value in their specifications it would be awesome. Then we would be able to really compare.
What I wanted to say is that you should not be fooled by the Chinese LEDs' "wattage" because that's not how you can objectively compare LEDs and by extent, LED panels/fixtures.

what up matchbox thanks for the compliment , if your in the UK check out viparled for sure they are based out of there i used their panels for that run i posted there and they treated me very very well :D blackstars are good units too a little on the cheaper end of things but they produce for sure and they only offer a 1 year warranty which kinda worries me.
Right it's been a while... I looked up the Vapar LEDs but they all seemed to have 60* lens angles, I need a full 120* spread because my grow space is very short and I've seen what those ridiculously focused 90-60* lenses can do as far as bleaching.

anyway I've been researching my ass off over these bloody things and have found a company called Grow Northern who are UK based and seem very legit, they are releasing a new range of lights that are basically plug and play, so you have the ballast and drivers all there that can support all of their future releases. The point in them is when you want to upgrade all you need to do is buy another module to (set of 15 or whatever, 3-5w+, whatever the future holds, LED lights).

anyway check out their site, I think I'm going to give them a go!

(if I can scrounge a few more quid I want this one XD ^)

let me know how they look to you guys, it would definitely help me with some other opinions :)

Cheers again guys!
 
Those are probably the best lights on the market right now but keep in mind that if you upgrade the 15 LED cluster you have to upgrade the power supply too. Each power supply powers 2 clusters and all of the clusters must be the same for the light to operate properly. Again, great lights but it may not be as upgradeable as you think and a ok price from them too. I know how and where to get a much better price though.

Fair enough thanks for the response, good points! I'm more thinking of just an LED light not worried about upgrading it, that just sounded like a good addition just in case of like for like replacements if a fault happens. Where would you get it cheaper or are you talking about a different brand. I'm still looking at Blackstars for their price.

Blackstars are probably the best bang for the buck. If you go for a more expensive company make sure they will both be around and actually honor their warranties. Over the course of an expensive light's 3 year warranty, i can replace my blackstars if they break for the less than the cost of the expensive lights :) if they don't break after 3 years i saved substantially. I already saved/smoked the cost of the leds in street price bud.

Just been doing some research and a few emails later, into the GrowNorthern 'modular' series, basically it works out that if you want to upgrade, the power etc is supported up to 5w diodes and the rest is just a software driver issue, so what it seems is that each 'module' (array?) is self contained as far as the drivers, heatsinks LED's etc and they just plug into a 'universal' power port that is in the chassis, and all that's needed to make them work is a firmware update sort of thing.

But yeah properly upgradeable or not... I've done some maths and decided to stick to my guns on this one, mainly because I like the Idea of the removable lenses and all that crap but as a test for the LED community in finding another good UK supplier (and the additional 30w on top of the 240w blackstar) is worth the extra £90 for the sake of experimentation.

And like Senseimilla says, they pay for themselves, only need to get, what 1.5oz with how much street price bud is these days and they've paid for themselves :)

Hey Matchbox Have You Considered Area-51's Led They Have A Life Time Warranty.http://area51lighting.com//index.php?main_page=index&cPath=2&zenid=6dd03c8da8467df3a333af4e7528ada3

Hi,

I am new to this thread and just started with LED about 2 months ago. I have 1 bloomberg UFO that I bought on Amazon, 1 prosource penetrator and 2 led panels from bonsai hero at http://www.ledgrow.eu/. So far the panels from hero seem the best performing. They cover around 2 sq ft per panel and cost 240 each. I am just in late flowering using these but they seem to at least match the badboy T5 setup I also use.

Got any pics with Han's panel?????.............and how high above the canopy do you keep the panels during your late flowering????...........thanks

for anyone thats interested i just started another LED grow running 2 vipar A300's again but this round im gonna scrog and only have one HUGE plant gonna be lots of fun and learning for me :D the link is in my sig cheers all
 
So I have some info some should find interesting. I set up a led light array on a 6 ft light rail. The array is made up of 3 - 90 watt UFOs with 20 - 9watt 3 led spots. The 9w spots are mostly white. Warm and cool.They are regular E27 base made up of the parts off a few bathroom mirror bar lamps. They clip onto the ufos easily and can be bent to point forward and widen the pattern of the array. i really think these white lights help a lot. I see that some manufacturers are adding more white. The way I have done it is cheap. The UFOs were about $75 each on ebay and the 9w bulbs about $4 each on ebay. The whole thing is about 450 watts for $300. Before I was using a 600 watt HID on the same light rail. It worked OK but so far this grow looks better with the Leds. I am still in veg for another couple of weeks but the plants are more compact than before. I am hoping that they flower fine. I still have the 600 watt HID so I can accessorize if I think it is needed. The space is 4.5 by 8. The array is hung off a bar and attached with hangers to another bar attached to the light rail 3.5. It has to be properly balanced. The whole thing is 1.5 ft across by 4 ft wide. I feel like that this rig would work fine for a 4.5 by 4.5 space (on a tracker) but it is stretching it to do 4.5 by 8 ft. I am thinking of adding a dolly on the rail and doubling the array. That would be 900 watts and hopefully would perform better than a 1000 w hid. The most interesting info is that regular 9 watt spot bulbs can be made to work well. If you add them to the red/blue ufos they significantly improve the growth rate. The ufos I have are kinda the no-name brand but seem to be working fine though may run hotter than some other models. The UfOs have 1 watt chips. The tracker helps a bunch but there is a question of how far you can push it so that the opposite side of the light does not go cold. I may also add some fixed spots to the ends to act as a fill to stop the plant processes from going cold until the light passes again. There probably is a Arcadian rhythm to all this. I got spectacular results in a smaller veg room with a 2 light array in a 3x3 tent and a tracker with 10 spots. As soon as I added the white spots and the tracker the whole thing came together and grew very fast and bushy. Even in crowded conditions. So now I am trying out a 3 light array with 20 spots in a larger room and hope that it will flower successfully. If not I will switch the center UFO to a 600 watt HID or double the 3 light array with a dolly so the tracker will only move about 3 feet, in two sections. What do you think? So far it looks great for a soil grow.

I am not affiliated with this with this LED company other than I use their products in my own very first grow. I have found the most educational youtube video that I have duplicated on a much smaller scale. Forget the named product if you wish. Again, I am buyer of this company's products only. Watch Brians youtube video. Please, I think you will be seriously impressed. Brian does not represent this company either. He is only a customer. please check it out.

In the youtube task bar enter the following: Growing MMJ Using Prosource Worldwide LED Grow Lights. And please count me in on this thread. Am very excited to be here and will share everything about my grow. I copied Brian to the "T".

I have mostly had success with ebay. I know many people believe there are different quality in lights that have the same spectrum and strength. I would be interested in proof of this. I see a lot of marketing here and I can assure everyone I am marketing nothing except the cheapest way to make it work well.

I have had great success with 9Watt led spots which you can now get for about $3 each on ebay if you buy 10 at a time (from China). That's .33 a watt. They also have the advantage of being able to point them places. I have added them to a array with 90 watt UFOs. 90 spots with 3 UFOs. I point some of them forward (in each direction) because there is a tracker and it seems to help the plants not go cold when the light is at the opposite side. I use old bathroom bar lights, salvaging the sockets with wires and some have metal tabs that can be slid into the frame of the UFOs. I solder all connections, tape and shield with plastic auto wire covering then solder a plug on these strings of 6 to 10 sockets which hold the spots. They look funky but are safe and work. The spots are just standard E27 sockets with 3- 3 watt leds. I use both warm and cool. I also use some reds and blues. They are now selling small spots with the red and blues of the Ufos. They are a bit over $1 a watt.

I have had great success with using white spots in a cloner. It is an ebb and flow with rockwool type and cost less than $20 to make. I make 45 clones in a small space (8x11 inches). Basically the plastic drawer to a Walmart sock drawer. At first I thought I would not work and be too crowded but it does and even seems to work better crowded with clones. Not sure why or if it is really true but I do get clones in about 2 to 3 weeks at about 90% or better. So I did a led vs cfl cloner test. I made 2 pretty identical cloners. On one with I used 2 - 40 watt CFLs and one with 4 - 9 watt leds. 2 warm, 2 cool. The LED tray did far better and the ones right under the leds did best of all. It was not scientific as there were other variables but showed to me that Leds work great for this and since that test have made 2 batches with success.

I also have excellent results in a small 3x3 tent Vegging with a tracker and 2-90watt UFOs with 10 spots. It only moved about 2 ft on the light rail but it seemed to help a lot. This room was stuffed with 36 plants from clones for a month. They grew well and remained bushy and healthy. They were in soil bags I make out of landscape fabric. (6x6x12 inches) These are the plants that are now in the 4x8 room.

I have read many post about the comparison between LEDs and HIDs. It seems that many have an almost religious zealotry for their preferred technology. I have never flowered plants with LEDs but will attempt it soon. I am not convinced that HIDs will be needed but am considering running a test in my 4x8 tent. In 1/2 the tent I'll use my 3 - 90watt UFOS (450 watts total) with spots and the other side a 600 watt HPS. At present I am vegging with just the UFO array on a tracker. It's coverage is not adequate for flowering but it is doing a good job at present with almost the full 4x8 in veg. So in 1/2 the UFOs and the other 1/2 the 600 watt HPS. They can be on the same tracker with a add a light kit. Not bought but made from crap lying around the metal pile out back. So they will both move about 3 feet on the tracker. That will cover the 4x4 of each area. I think that UFO array might be able to do 4x6 on it's own but then there would be no test against the HPS.

Not sure I want to risk this and end up with a low yield. The safest way would be to just add a 600 watt HPS to the LED array, removing the center UFO and putting in the HPS. It is more complicated cause you got to use a cool tube and then track the whole room (7 ft). I designed this system but have not tried to set it up. You know how it is. Roll one up then come up with all sorts of crazy ideas. But some of them are right on so?

I am a bit surprised I have not seem a direct comparison with 2 identical rooms. One with LEDs and one with HPS for flowering. It must have been done but maybe nobody's saying for some reason the results. You read claims but then the next sentence is "Buy my product".

What you Stoners think?

HID isn't needed - I did full LED last flower and it came out like any other crop some plants dense, some less. I got solid yields (avg 3.5 oz/plant, one over 4). I'm doing HPS + LED this time just to see what kind of difference/extra yield I see, though it won't be a solid comparison since i'm growing vertical this round too.
