Show me an LED that actually yields what it promises

[toohighmf]

its all in the title.. show me an LED that is less than half of a 1000w that actually yields similar to a 1000w. sick of the hype and no proof. someone please show 1+ pound per 400w unit! I can't afford to gamble on a federal crime.

So far all I have seen is poor yields. I'm a commercial kinda guy, and no one has even come close to impressing me on a commercial level. If you are killing it with LEDs, pease let me see the proof! if you could, I would really appreciate the brand and wattage as well as spectrum (nm) and your Gram per watt estimate. I would really appreciate it.

yeah,i dont believe they will yield anywhere near an h.i.d. the light intensity is just not there. you can mix as many spectrums as you want,talk about micromoles,and say lumens dont count cause plants dont see em.

Im sure it may be a good veg light,but i love the t-5s. When it comes down to it,its hard to beat the light intensity of a 1000 watter for fat -ass buds.

I recently saw some leds in a 4ft t-8 array , 22 w each, mixed spectrum . Fixture was cheap , but the bulbs $82 each!!!!..........
SOme were both led and t-5 50%/50% . Looked promising , but like you guys said lacks the intensity 2 feet away from the light.

I pulled a pound in a drip hydroponic system with large plants in coir/hydroton grown under a Lumigrow ES that uses 330 watts per light & I have posted about it several times and have plenty of pics in my gallery. I did use some small T5 striplights (6500k) around the perimeter of the tent and canopy for some added side lighting and far red spectra. The big strong plants shown in my Swt #4 IBL project thread were all grown under 2 of these Lumigrow lights in a growlab tent and all the seeds were produced with them as well and were very big and healthy. They are very rich in the blue & deep red spectrum along with some white led's in there too for good measure so it's much more complete than say a HPS spectrum alone. It grows very sturdy strong plants that are very dark green with big healthy root systems. If cost is a non issue I would roll with the Lumigrow ES.

I would say it's a realistic comparison that one of these can replace a 400 to 600 watt HID. They are very well built, very bright, and they are not cheap but if you call them directly I think they will take a few hundred bucks off the advertised pricing. Hope this info helps and in closing they are very quality lights or I would not use them.

1rst dont listen to the claims
Only osram , philips, n cree work on par with hps
Will cost you a hp for a 1k equiv
Most leds that are efficiant hv only been out 9 moths guna be hard to find a grow.

This is a cree light

Damn, you really narrowed it down to master growers only. I believe once you get to that gram/watt, you have no reason to experiment with led because you are rocking.

Using LEDs require a even and short canopy like scrog. They just do not have the penetration of HPS. The few benefits i have noticed in my grows is the LED produces fatter and heavier colas. With HPS, some strains stretch an too much.

Go look at my plants and grow under Lumigrow lights, they have 5 watt led's and they penetrate down very well even on 3 or 4 foot plants and with proper reflection on the sides (mylar) and some minimal supplemental lighting (HO T5 striplights) you can get amazing results that can rival that of HPS grown buds in the same timeframe. Plus with LED there is no infrared and the potency & resin production is higher from what I have seen. Same goes for aroma & taste, better with LED. I am of course talking about high power LED growlights like the Lumigrow not the cheap shitty chinese ones on ebay. Go look at the lumigrow website last time I was on there I think they even had something about a money back guarantee on performance.

No offense but the 3 year old limigrows use Old philips 5 watt chips that only put out 20 percent more light than the 1 watt philips luxons that came out this year.

Don't buy old tech

Leds are like cpus they keep getting better

I don't believe this is correct information but would you care to cite your source for this info? Are you referring to the red, blue, or white chips?

Also, this % figure you randomly gave that I don't think is true would not really disprove anything relative to their excellent performance or the fact that they have industry leading technology like their top of the class drivers for instance along with being the highest quality LED light made right now in the growlight business.

The United States Department of Agriculture (USDA) uses these Lumigrow lights!

Thanks.

While I agree about buying old tech, I was wondering where you got this information - I thought that the previous model used Phillips Luxeons and the current model was using another manufacturer's chips. Can you point me to a link?

*edit* Here is a quote from Lumigrow that I found - "We no longer use Philips Luxeon LED's. We now use a US made LED's that have over 70% more optical power than our previous Philips Luxeon LED's".

Must be why they grow such big fat juicy frosty Sweet Tooth plants & seeds

 

[FreedomGrower]

I didn't say leds don't work

Apparentlythe old 330 used Philips
Now they don't state what brand they use

You show me the specs of a red 5 watt putting out 500 or more lums and I will shut up

Till then i only recommend efficient 1 watt chips

Ill try n call lumigrow tomorrow and find out more info

So if it puts out 70 percent more than the 130 lm philips thats 220 lm or 45 lm a watt still only half as efficient as the best chips

I wonder the motivation of ever defending a manufacture who doesn't even make the leds

 

[SOTF420]

Even if a 1 watt chip was "more efficient" is still does not have the intensity, output, and penetration of a 5 watt and I believe the LED's in the Lumigrow are fully driven as well to full output because of the superior heat management which allows them to do so without affecting the lifespan of the emitter. 1 watt chips are not driven to full output anyways so they are not really even a true 1 watt technically speaking although they may have the capability the shortfalls lie in the inferior other units and the run of the mill drivers (power supplies for the LED chips) most of them use which in the case of Lumigrow they actually built theirs from the ground up using only the best components and have many years of experience in the lighting industry plus some models before this newest & latest ES model. All the reasons why I got these instead of any others and trust me I can get any of them.

They are very bright, SAFE, and the 5 year warranty does not hurt their street cred either. Plus on top of all these excellent attributes they produced the very high quality Sweet Tooth #4 IBL generation of seeds like champs so for that alone they will always be legendary & epic LED growlights in my book.

Keep it Grapefruity!

give me a 600 unit that pulls like a 600 w no heat hat lasts 5 years and i'm sold.

 

[rives]

You show me the specs of a red 5 watt putting out 500 or more lums n i will shut up

If by "lums", you are referring to mw of radiant flux, check these out. I think that these are a very recent release, but I had been wondering if LEDEngin was the supplier to Lumigrow - there aren't many US made LED's. These look pretty similar to the units that Weezard used in his fixture that have been unavailable for quite a while.

http://www.ledengin.com/files/products/LZ1/LZ1-00R200.pdf

*edit* After further thought, it seems that Weezard used 15 watt chips from LEDEngin.

 

[SOTF420]

toohighmf - I'll take some of those as well! Who wouldn't right?

But they all make some heat and they have multiple fans running to remove it from the unit itself which they are very good at. How much heat? Well not nearly as much as HID of course and the unit itself only gets warm not hot.

The ones that don't produce much heat generally are not very high powered lights output wise when it comes to LED as some heat is going to be generated no matter what because no light production is 100% efficient and the byproduct of this is heat. I would say a 330 watt Lumigrow ES produces about 25% or so of the ambient heat a 600 watt HPS would and way less than a 1k HID. Plus their is no infrared light being made, only PAR light which plants can use to grow.

Last year they were running a sale on them during Halloween or maybe Thanksgiving I think it was for $999 each. A friend of mine called them up recently and paid $1200 I believe for one. I'm guessing if someone wanted to buy a few and called them directly you could make a deal since they are a private company. Okay rant over, Lumigrow kicks ass FTW!

lol What a bunch of crock 1 watts can't penetrate; that's why my custom osram penetrates more than my HPS

I also have my custom array set up so I can control how many watts my leds get ... they are bright from .8 watts; and I can drive them up to 3 watts and they do not even get luke warm ... I wonder why some leds run so hot?

... they are putting out half the lums of the 5 watt chip of course there guna penetrate + you can have 5 times as many of them and the array uses the same amount of wattage..

5 watt led engine 600MA flux MAX
1 watt osram 330MA @ 1 watt (1-3 watt chip)

radiant flux is another way of measuring lums; converted looks like about the 220lm I stated

350ma of radiant flux is the same as 100lums; they measure it in radiant flux by default for the red spectrum

Cree puts out about 60lms a watt
Philips & Osram 90-110lms a watt

These are the osram led lights I really want ... water cooled bad mofos

I made mine because I have zero trust in led manufactures. I may have used older ballast parts lol but I had a Masters in electrical engineering design my light correctly ...

If I can get over 2grams a watt with them I will them look into the commercial units

 

[FreedomGrower]

And since I got my first ever negative rep in 5 years online (beside dusty lol); I will now end this conversation and help people with intelligence on the private site I belong to.

... and bold the light that is the best on the market and I still wont promote over a hps (due to cost) ... since he can't read my post and see the alternative I listed ...

Show me where the lumigrow puts out more than 20k par lums

Converted how (or why)? From the Osram spec that you put up, they appear to be the same thing to me.

*edit* Ah, found your edited answer - kind of hard to follow when you stick the answer up there. When you talk about driving the Osram at 3 watts, are you using the LH W5AM chips?
