Watts are not all created equal. 50w at 90 lpw is only ~ 66% of 50 w @ 140 lpw, as well as how they are being driven.

50w of low quality china-made emitters cannot be compared to Cree, Luxeon,...

It ain't about watts, it's about umols/m*/sec of quality spectrum developed specifically for mj.

Put the same 'wattage' of badly developed spectrum emitters over one plant v quality emitters over another. Do you really think they are the same?

How are we going to unconfuse the potential buyers, when we confuse the 411?

I like A51 use of umol charts, especially 2ft down and 3 x 3. Pretty impressive


I know, but 28.8w/sqft. is pushing it for a light with no secondary lens. The reflectors machining quality do look impressive in spirit of all hans & grans products, but it's not going to make up for the lack of secondary lens by a long shot. This is more like a 12" x 12" with plants no more than 24" otherwise you're gonna get airy buds deal to me. I ran a pair of BD700's at 18" for a total of 1400w and even then only got about 18" of actual penetration meaning the buds were fully develop and the rest were small filler buds. One must consider even sunlight can only penetrate an honest 24-36" because leaves are specially designed to be very effective solar panels. This seem to be the max. because if you've ever grown a Humboldt size 9ft.+ outdoor tree, the branches pretty much max out at this length due to the sun's penetration limit because these monster will probably get bigger if it could penetrate any deeper. Hold up a leaf under the sun and examine the see how dark that shadow is and it will give u an idea how effective it is, leaving mostly weak deflected and diffused light left for the undergrowth. Plants rely more on the sun's movement to change the angle of penetration to enable direct light contact with the inner and some of the lower growth.

I'm not aware of any Chinese lights that can do it at 28.8w per square foot.

I've never used them, but 28.8w/sqft. it's 36% less than the recommended 45w/sqft. If these were secondary lens equipped, I would be much more convinced that 28.8W might do it, but they're not. I also notice u guys recommend the 190's for a 3x3', which would put u at only 21.11W/sqft. as this is less than half of the recommended 45W. Even if this was true, my standard workhorse testers 100x3w pulling 220w running my white spec. will put 55w/sqft into a 2x2" for $149 shipped. And yes, this factory offers the same Crees they install a well know brand and I trust them because everything checked out as spec'd on my other panels but I chose not to go with Crees because the small difference I can more than make up with sheer wattage without incurring extra costs. I realize that the Crees are more efficient, but not by 3x if you compare price performance and cost-effectiveness. Hey, I'm just a messenger but this stagecoach's armed. lol.



45w per square foot, sí.

Whenever you have blogs recommending "the best" per se, it digresses into a subjective shooting match as ubiquitous bloggers proffer their opinions disguise as objective facts. The same happens whether the product are pianos, tennis racquets, LED TVs or in this case LED lights. I applaud you monkeychief and Eraserhead on cutting through the hype and bs and shedding some "light" on the subject matter. As a consumer with limited funds and as most blog readers are in the same boat, we are more interested in the affordable and effective LED light where marginal utility balances with marginal cost. Of course Lamborghinis are desirable and quite nice, however a Hyundai Elantra will get you there and back effectively as well. Advancedledlights are fine but are they really worth more than 2 times the cost of similar Eshine LEDs with the same 3 year warranty and the same power draws? I would rather buy 2 EShine LEDS than one Advanced LED and have money left over for nutrients. Advanced LED doesn't talk to anybody and they operate out of a strip shopping rural area in Podunk, Arkansas. I would surmise that there are no botanists, fabrication labs, etc. on site. They in fact started out selling pet furniture on the internet who jump on the LED craze. Who's to says that they don't coop Chinese designs with minor cosmetic changes perhaps like Kind and Growace. One thing's for sure as monkeychief noted, you will be paying much more from any U.S. seller vs. the ubiquitous Chinese panels. In certain cases you may know but in most cases, you certainly have no clue who makes for whom in the nascent LED market and what parts they are using. We are growing weeds right, not rare orchids for crissakes. Just my $0.02.
Thanks E7,

I couldn't have said it better myself as this is precisely why I'm often misunderstood and labeled as a promoter of cheap factory directs. Reality is that not everyone's made of money and is in this for business. I can easily recommend high-quality/price makes and make myself look good but that's not going to do the majority of the people any good since most of the time, generics will always be a much bigger market share vs. brand-name.The reason being is this whole industry is a total rip-off cause they're basing on the finished product's extremely high market value so we growers tend to overlook the costs. Our meds are 1/3 the value of gold that can be produced every 2 months making it the new green gold and they know is therefore; on average we pay bout a 40% premium on canna-specific products.

I tried not to disclose who makes who as a professional courtesy, but this is what I've been talkin bout. There's no need to pay a so-called more cause they're so-called brand-name companies that claim to have their proprietary spec. that they've developed when most of the time it's just one of the 4-15band red spec. that's tried and trued by some real pioneer like Mike and his GLH Spectra's. 6 yrs. ago when there's only a handful of us based companies, Mike's panel was the first one that worked finally had the yield and density that was acceptable. Almost all other brands were still much farther behind in terms of spectral tuning and performance.

Back to the future.. Try these monkey steps that will hopefully help u avoid some bad experiences.

- Try to stay away from companies based in Hong Kong. Reason being that almost if all factories are based in Shenzhen a town within an hour from HK in China where most if not all of our grow lights are made. The ones based in HK are mostly brokers that buy direct from the factory and resell them via alibaba and the likes.

- First and foremost ask them for the actual draw wattage, par at 30/60cm, any secondary lens(nice but if not, ok as long as there's enough wattage). Make sure to take notice of the manner and willingness to provide the requested info. Any hesitant or excuses is a def. red-flag. U will find this on the current 5watters with the exception of A51 because they get it regarding the design and shortcomings of the 5w chip itself.

- Warranty and replacement/repairs of course.

- first time order Paypal if possible or similar merchant services.

- Try to stick to these factories and u should be fine. CT, E-shine. Evergrow, GEHL, and LG(TopLED). Others I can't comment. Please note that some of these are better than others but I rather name a few to be ethical.

Again, we should applaud EH for verifying what I've been saying. This shows his honesty and professionalism that this and many other industry lack that a person would say something on behalf of the customers even realizing it might ultimately hurt his business. As with any product and services, there will always be different levels and budgets, it's up to us to select the best option for our application. I don't get about these brand names patronizing thing. I always thought you're not supposed to be talkin or even remotely referring to your hobbie for security reasons. This is especially true these days when those professional grow jackers might be anywhere and accidentally overhears about the latest panel u just installed. At the end of the day most of the info u need is only a keystroke again but the problem is there's so much bs, biased, or just plain ignorant spin that u have to invest the time to be better informed.

I agree, but how are u going to get the par without the wattage? If u notice on my posts, I like to go all the way to 3ft. The spectrum is a given because without it the growth would be whacked. Umoles is everything but how are u going to deliver it? I've always had my doubts bout the cob regardless of makes except Illumitex.

Some great advice and obvious that you've done some homework on this. It's a huge playing field and there are many vendors more than willing to take your money and run, caveat emptor (buyer beware). That said, there are some respectable lights out there for the money and as Edge said, we are growing weeds, it doesn't have to be complicated, nor do you have to be a brain surgeon to grow them. Personally I've bought some of the LG's and for the money I'm happy with them, but I'd have no problem calling a spade a spade and moving on if they didn't work. I have 2 of those (crap) panels as well... live and learn.

No, of course not, but if you're talking about the performance difference between say Cree and Epstar, it's not proportionate to the price difference. Regarding the quality and reliability difference, I've personally can't tell the difference since I think 2 of my brand-name makes are supposed to have Crees. Apache is a sure thing, but the others I don't know as with most people I never bother to look since it's not easy to verify and I don't have a spectroradiometer to verify the wear and tear. I never doubt Cree are the best because they are. I'm just saying for the people who do mind paying more or on a budget just can just opt for the standard brands as long as they stay away from the real cheap leds. This goes back to selection process, u just have to be as careful as possible and do your homework. Like E7 said, a Lambo's nice but a Hyundai will also get u there and back.

How are we going to unconfuse the potential buyers, when we confuse the 411?

Sorry, it wasn't my intention to do so.

haha potential buyer here... far from unconfused since subbing to this thread. the amount of info in your heads on the subject is impressive. i have three 4x8 footprints that i would potentially transition over a year or so from t5/HPS combo to an all LED setup. sounds like there are many options varying in price by the thousands. think ill wait a bit longer till i feel more confident in a move. ill definitely stick to this thread n read all the info as it comes :)

When someone mentioned Lamborghinis, monkeychief (Post #2367) said he owned one at one time.

When someone mentioned ApacheTech, monkeychief said he owned one of those (Post #2369).

When someone mentioned being to China, monkeychief said he's been there often, running his construction and granite business (Post #2377).

When EH mentioned visiting Chinese LED factories, monkeychief said he'd been to CT, E-Shine, Bysen, Topline, and Cidly (Post #2383).

Amazing how monkey's been to all these places and done all these things.

I've known a couple of guys over the years who've done everything and been everywhere. Most of what they said was made up.

No, I apologize for the confusion as I didn't go back to reference the specs. so I simply divided the total rated wattage into the actual draw wattage to reference the actual in relationship to the rated wattage.
16w total divided by 11wactual = .689
Gotcha thanks for clarifying. So 11W power input - 15% for driver losses, we can call it 9.35W of dissipation in the LED. At 30% efficiency we get 2.8 PAR Watts.

What's the top led for around $550? Any hands on experience with Lush Lighting? I saw subcool using. Im really close to buying and need a real good yielding light. Or two less expensive lights. I would like to do a 2x3 scrog. Maybe Six 3 gallon pots. Going led to avoid heat issues. My closet grow room is too hot with 600W hps. Too much cooling power. I'm asking a lot for a first post, but I really need good advice

Hi, guys. I have one of these, have not tested it yet. What do you think about it? I know that it is from China, but if parameters are as they are written, then it should work? Shouldnt it?

When i plugged it in to socked it was bright as 500-600w hps. Leds look kinda good as well.
When I connected it to a "power meter" it showed that lamp takes 100w +-, as they told me.

I also hate and have no patience for bs as those who know me, I like documentation since I question everything including myself. This is why I've always stated my posts are actual hands-on experience to inform potential new buyers in spirit of the thread's name.

I question the wanna-be led cartels in the leds business and my credibility gets immediately questioned. Well, do I also need to disclose my blood type to participate here now?

oooh....monkeychief, beautiful grow brotha man. Do you know which factory makes the green light on the left? Have you ever tested the #'s between the different switches [modes] before? I have looked at these in the past and I like the setup, especially with reflectors and NOT lenses, kudos!

Would be interesting to know some of the intimate specs that are usually NOT provided with that particular type of light. Epistar's maybe in these too?

Thanks. It's one of my veg. test with 16 different strains under red and my white test spec.. Yes, the switches are more of a marketing pitch rather than an actual useful option and also goes against the kiss principle. Besides, I don't see the point in reducing the wattage in vegging since our leds is nowhere near the intensity of sunlight as this is the reason why u see the Humboldt guys grow those 10ft monster tress pulling almost 10lbs. I understand efficiency is always important, but as with everything, the difference has to justify it's added premium. This is similar with the small-bore high-compression/efficient motor vs. the good ol' big-bore inefficient but makes up with brute power and displacement. Efficiency has it's premiums, but the problem is greed takes over and most of the times in ends up in their favor not us end-users. An inconvenient truth, but is what it is.

The green one is a LG reflector model 144x3w running epstars and bridgelux I think. It's been running 18hrs/day for almost 3yrs. without a single glitch. THe reflector helps but nowhere near the lens though. A well design secondary lens can dramatically enhance the par numbers. THe other is a standard GEHL 100x3w, my main workhorse, simple and extremely cost-effective at 149 shipped. I use these for my spectral testing/tuning. They pull 782umoles at 30cm which is very hard to beat for the money. If u wnt a no-frills most band for the buck, period. U can pretty find these everywhere but some of those might be the bad ones from some of the ebay vendors. I can attest for these from personal experience. The others, "caveat emptor" cause again, greed has no ethnic or national preference.

Yelp. Another nice thing bout going factory direct is most of the time, you can get custom spectrum request at no additional costs. Something most of us americans are accustomed to paying a "special order" fee. Again, greed has no boundaries.
