Whats the best LED grow lights?

check out my topic it has alot of good led lights and i bought mine a week ago and already got them and there perfect there 3watt ones and there the same ones your looking at just from a different person  but mine took 16 hours to arrive

I just ordered mine yesterday, got 2x vipar v400's got very good reviews for a mid range product, shipping is extremely fast aswell mine are due tomorrow according to the tracking info, very excited ha.

Here's the link

Sooner or later im going to have to break down and start buying some LED's. Like a pallet load.

 

Got my cabnit and my gosh it is pretty huge it can fot quite alot of autos

3 watt if you have a small vertical space, 5 watts if you have a taller space.  The 5 watt need to be about 12-18 inches away to avoid bleaching, while the 3 watters can be within 6 inches.  I personally run a bunch of the mars II's and have been happy with them and previous to that I had various 3 watt lights (blackdog's, stealthgrow, and a few random ebay lights).  

In terms of growth I noticed no difference between my cheap ebay lights and the name brand ones.  I also noticed a substantial difference in penetration when switching from 3w to 5w LEDs.   

 

I Have been planning  on buying a 600w HPS cool tube set up. The ballast, bulb, tube, ducting and a fan are going to cost a few quid so I'm thinking of paying a little extra and getting this 1200 watt LED panel http://pages.ebay.com/link/?nav=item.view&id=321370534949&alt=web  it draws about 600 watts so pretty comparable to the HPS and I'm thinking it would run cooler. In the summer my house can get to 30'c so a cooler system would be a big advantage. Has anyone on here tried one of these out? And do you think yields could be comparable to a 600w HPS? 

 

IMO, the best LED light is the cheapest.  You can use that as a paperweight, while growing gorillas with an HPS.
 
Honestly, there are some good HPS out there, but those are the expensive ones.   The ONLY benefit of LED  (in flower) that I've experienced is that they tend to coax plants to begin flowering sooner than HPS.  My assumption is the abundance of focused red spectrum helps trigger the flowering stage sooner than standard HPS.
 
I think the blue spectrum LED are great for veg growth, but based on my experience with LED in flower, I prefer HPS. 

 

Oh yeah, good to see you Gold!

 

I did a lot of research and decided that two of these will do just nicely

My first harvest was 6 oz off of three plants in my 4x4x7 tent. Now that I know what I had been doing wrong I feel like this harvest will be atleast 1/2 lb

Wow man that is some crazy price. 6oz of over 600watts is pretty terrible. I might stick to HPS, you can get 20oz with 600w HPS

 

just as long as you're keeping an eye the future. . look at the incredible factors like extremely low heat. I can keep my hand on the light indefinitely. There is also the low cost to run vs hps/mh

So basically the led lights cost way less in the long range.

On average the yield is 10-20% lower than with mh/hps but everyone is always telling my my quality is incredible.


If you go with led lights try to go American. My lights are made and assembled in the u.s. (if you're not American then use whatever you'd like ). All just my opinion.

I don't want to sound argumentative but that's just not true, yield isn't 10-20% lower, the difference between 6 and 20 is about 340% lower. 20 is over 3 times more than 6. 
 
The cost to run depends on how much electricity it uses and if it draws about 600 watts then it draws about 600 watts. It doesn't matter if it's LED or HPS, only how much electricity it uses.
 
Even if the units are assembled in America you can bet your ass all the components were made in China anyway. I'm in the UK, I don't mind buying from the Chinese.
 
The heat is something I can't comment on. I'd love to compare the heat that comes off a 1200w LED and a 600w HPS because they use about the same amount of electricity. Not just compare the heat directed at the plants, but all of the heat, as most of the heat from the LED comes out of the back of the unit but still contributes to the heating of the grow area. 
 
I am tempted to try LED out but they are so costly to buy. A 1200w mars2 LED costs about £370 and a 600w HPS costs about £80 so that's quite a bit of a difference. A new bulb for an HPS costs about £15 and will need replacing after a year. The whole LED unit will need replacing after around 6 years so again, very expensive.
 
I want to try one but it's a huge gamble really

 

And the cost to cool the room from the HPS?  For reference I have nearly 3kw leds in my room and one exhaust fan with temps solid at 72.

 

That's a fair point but one I can't really have an opinion on, as I said I have never used LEDs so don't know how much heat they throw out. People often say they don't give off much heat but usually they are comparing an LED that draws about 90 watts to an HPS that draws 450 watts.

I have seen people have the same daft comparison with CFLs and HPS. CFLs are well known to give off less heat than HPS but I have run two set ups side by side 3x 125w CFLs against one 250w HPS. The CFLs use 90 watts each so they total at 270 watts combined. The HPS bulb and ballast use a total of 270 watts also and I find both systems when ventilated at the same rate actually run pretty much at the same temperature. Furthermore the lumen output is almost the same too.

My point is getting a fair comparison seems to be uncommon when people compare lamp types.

So you have LED lights totalling at 3000 watts? Do you know how much do they draw? What size is your grow area and what ventilation do you have in place? What yield figures do you get from that? And could you put up a photo of your set up? I am very interested in LED grows and I think it's the future especially when better diods are brought out and the price drops. Even in the last 5 years the price and efficiency of LEDs have come a long way. I wonder what they will be like in another 5 years

 

I started with HID and went from 400 to 600w to LED (SS800 CLW).
 
PRO: More uniform light distribution.
          At least a 5 year lull between light (i.e.. bulb) changes.
          The light doesn't degrade over time (like during the grow).
         More light generated for the same power HID requires.
 
CON: Weight (more then a HID with a steel hood).
          Heat (my application required a heat manifold)
 
My yields and potency are great, I am never going back to HID unless it is an emergency.

 

What sort of yield per watt are you getting @[member="jollyrancher1"] ? 

 

My record is over 18 oz.
 
Usually between 12-14 oz.
 
I give away a lot of stuff I just don't want to deal with.
 
I am very happy with the yields and potency.

 

 
I take it that's an 800w LED panel? Do you know what wattage it actually draws? Would you say it produces less heat than the 400 HPS?
