LED Grow Light Review & Comparison

[smowstack]

Another interesting finding in the study is that light quality is much less important than light quantity. While light quality will govern certain aspects of plant metabolism, it has a small effect onphotosynthesis, which is the most important driving factor in plant development. While this goes against what many LED grow light manufacturers have to say about their products and the wavelengths they put out but, the fact remains that HPS lights are still the workhorse of the indoor cannabis industry, and for good reason.

yes, we all know that. We are looking for something better. That old 600w is the best pot growing work horse they ever invented. So that is what we are kind of comparing to. Everybody knows you can grow top shelf pot with a 600. But it's heat and expensive to run, so we are just looking for something better. Is it possible? I don't know. They claim it is.

Grow rooms with highly spaced benches will benefit from LED lighting because it provides a more focused beam. On the other hand, grow rooms with more of a “sea of green” would benefit from HPS because less light would be lost to the floor or walls in its wider beam. LED’s have the advantage of being cooler to the touch and they can be used right in between the plants where 100% of light emitted gets captured. The precision delivery of light in LED fixtures also makes them ideal for supplemental lighting
with efficiency the only real thing going for LED and only thing they use as a fight towards HPS the truth really hurts when double ended bulbs being the best option for higher wattage fixtures, say 1150 - 1215 watts For larger scale operations, a careful layout of the garden and its lighting is essential and can save a grower thousands in electric bills. Specially for the real cash croppers

Notice how the title of this thread is "LED Grow Light review and comparison." Fuck off. You don't even know wtf everyone here is talking about. You sound like a complete asshole talking to himself.

For the last time... HPS generates less heat than the garbage lamps you're trying to convince yourself produce less heat. HPS is more efficient than the particular LEDs you are using. That means it takes more power dissipation to get the same amount of power in light as you'd get from HPS. Stop trying to justify your poor decision using pseudo physics.

Edit: I didn't realize the light you were using advertised top bin osram LEDs. I thought you were talking about KIND

 

[smowstack]

LOL go back a few pages, there were at least 3 different COB companies mentioned. Apparently you need to go back and get your GED and you better brush up on your reading comprehension while you're there.

I checked out spider, and optics, not sure what the other ones were. Nothing clicked. They were talking to nerds who like lights, not farmers who like to grow pot. That's how I ended up with CLW. They presented their product in a way I could understand. "Here's a $439 light which will cover 2x2 and should be as good as a 400w mh."

 

[HiloReign]

Yes because the greater majority of people on here don't grow weed amirite? It's like talking to a retarded persons friend whom they call "retarded".

Here's another good COB company

I don't doubt you, there is no free lunch.. Not sure what an osram is. Not trying to justify my clw. I just know I enjoy it more than those old hot energy eating hids.

lol Church you knee jerker you yeah i do i would place bets 2 MArs 1600 watter will kick the shit out of 2 346 watt COBS any day of the week including Sundays
Yu guys put cobs like that make belief Jesus or the so called God you jerk to and pray for false hopes same fucking thing folk lore fairy tale i can post T5 grows that make cobs
look silly
So with that said best bang for LED in my books would be Mars in a heartbeat its affordable you get discounts
But i know its Chinese junk right lol 99 percent of that Cob DiY builds are probably china / japan parts with that made in usa sticker to market BS Don't fucking fool yourself ....
when Seymour duncan needed chips for his super computor he had to order it from japan lmao what makes this any different same shit made same place oh put together in USA in someones shed makes it made in usa right ???
We know who can fuck off with them thoughts preacher haha
everyone is worried about efficiency wasted power HEAT yeah fucking knuckle head Heat is also the driving force in plants and therefore needed with every 10 degree in heat will increase c02 up take and is really the driving force of any plant
Have run lots of grows with only fresh air coming in the dead of summer heat but guess what them 90 degree temps were also leaving my room in turn 80 degree temps coming back in from outside

Church whats the efficiency of them mars 1600 watters ??? compared to Cobs ???? and i stand my ground that 2 - 1600 watter will in fact kick the shit out of 2 300 or 346 watt cob units and for half the price life span 50,000 hrs also what tests have been done on cobs for light effciency after 10,000 hrs ?? probably not fucking one right

Im not sure what your talking about but my Kind LED doesnt need to be air cooled I get as much yield as I did with a 600 HPS if not better and it uses 40% less electricity.

I have no idea how you claim that equates to being hotter and less efficient.

Why are we even talking about HPS?

 

[robincnn]

Kind LED posted this comparison of all the major LED lights.

I've been wanting to get my hands on a K5 after my results with the K3.

What do you guys think? I would guess the results are legit, because anyone could reproduce this test.

The guy in the video is high on some burple crap.

Sorry I did not watch the whole video.legit...wth... It's like Apple giving reviews on major smartphones. Or hyuandai giving reviews on major car makers.

burple mutiny has been conspiring for last 1 week here. Hope they get tried soon or they buy a par meter to enlighten themselves to reality.

BTW that kind led would look nice with a spider sticker

a 600W HPS lamp has an efficiency of about 36% fresh. That's why. That's very high efficiency. If your kind can't beat it (it can't), there's no point in playing.

HPS produces more power in light per watt (about 0.36W PAR per 1W of dissipated power) dissipated than the epistars in your kind lamp can.

By contrast, my cxb2530 3000k u2 bins are 49% efficient. That means for every 1W of power dissipated, it outputs 0.49W of PAR. That type of efficiency justifies upgrading from HPS. It's a gavita killer. A fresh 1000W de puts out about 0.42W of PAR for every 1W of dissipated power. That's very hard to compete with, and you won't do it with your blurples.

Who cares. Why does that matter if HPS produces the same yield but needs to be air cooled and uses more electricity?

 

[churchhaze]

I also never said that being hotter equates to being less efficient. I in fact said the 2 are not correlated. Temperature is not the same thing as heat.

 

[churchhaze]

HPS doesn't use more electricity, it uses less. That's what efficiency means. I never said anything about "yield more". You simply decided to come up with your own definition of the word efficiency.

Efficiency = power out / power in

When something is less efficiency (like kind led), it means it takes more power in to get the same amount of power out. That means more heat. (it has nothing to do with temperature.).

This is a very stupid bet to make. You're comparing a lamp that can't even beat HPS to a lamp that wipes the floor with HPS. Why would you buy a mars after insisting LEDs are shit? We're telling you the mars is shit. If you buy the mars and conclude that it's shit, you'd learn nothing new... yet with your dense attitude, you'd likely use it to confirm your bias.

Don't be a prick. Get the fucking lamp we're telling you to get if you're going to be making a comparison, not the one we're warning noobs against.

WTF! My Kind runs at about 400w...it produces the same yield as a 600w HPS...Are you trying to tell me a 600w HPS runs at less than 600w, or better yet, less than 400w. Because that would be news to me.

Who cares about power in/power out, if it doesn't directly correlate to more yield per watt of electricity used.

How many grams are you getting from your 400W, and in what area? I pulled over 1.1g/W my last grow, and I considered it a weak run. Over 240g from a 240W lamp (80cri 3500k vero 18 at 700mA), in a 2x4.

I don't believe you can pull better results with your 400W kind than you can with a 600W hps. I'm calling BS.

 

[smowstack]

grams? who cares about grams? We already have all the grams we can smoke. Now we are talking about quality.

and that is why your pot and my pot is better than anything you can buy

It's getting to where you can tell the difference between factory pot and home grown pot.

I can tell you, this pot I am stoned on right now is better than any pot I ever bought. Could be just genetics. But it was grown in just some dirt with a light. And a light many experts who know more than me don't like. Who knows how good my pot would be if I started growing under the lights they like?

that's not a very good argument considering how old that technology is and that's why so many have moved on
