keep in mind even good weed, good growth, great taste, etc is subjective right?

@Ryante55
you mad bro? spent so much on useless lights? over and over? hoping for the power and heat save?....
Never used viperspectretes sorry--you take a negative review personal like you're a seller of
led lights thats weird

I wasted money on led then i got smart an learned how to use them an what to buy. Who cares about power savings? Most spaces I've grown have a limit to the power. You will get higher gram per watt numbers with led if used correctly that is a fact. If you have a warehouse sure hps
is cool but 4x8 or smaller and it's just stupid to buy hps. I'm sorry you can't seem to turn your brain on long enough to figure out how to use led. No I'm not mad got a bunch of led grown nug how can it be mad with a full jar.

When I researched it only Phillips made the bulb... What other manufacturers are manufacturing the CMH bulb now? The picture in the advertisement you posted to this thread uses the Phillips CMH bulb... The Phillips CMH bulb has come down alot in price but still seems to be more than double the price of an HPS with equivalent wattage.

GE, Ushio and other Chinese suppliers make CMH bulbs.
Below is a SunPlix double ended 630W CMH bulb and fixture.

That is different... You are running 6000 watts of LED?

If you and the trolls that seem to be jumping on my posts want to have a serious engineering discussion about lighting and yields I am all for that... From what I've seen so far, that isn't the case. I've been so interested in the topic I've bought three generations of LEDs and run them in flower. They are inferior to any HPS I've tried. If better specs made better yields everyone would be using LEDs. Specifications matter less than results... but, I guess if you only have specifications... Best of luck!

And these 3 lights are?

Color temp? CRI? Wattage? Any details at all?

I'm not sure what input you provided but I sensed multiple posters (trolls) trying to "amplify" your message. I find trolls to be as useful as lighting manufacturers these days. (Not at all.) When lighting manufacturers need to come up with a new specification that there are no scientific references for, no wonder average growers get confused. It doesn't help when snotty know-it-alls quote these specifications without realizing what a load of crap they are... Let me know when you want to start the engineering discussion... I won't respond to trolls...

No they’re several I started building a bit ago. Current ones in use are citizen 1818’s those are made up of 80 and 90 cri 3k spectrum. I built them to pull 600 a piece. It’s the reason they’re getting replaced with the quantum boards from hlgs 600h kit. They pull 640ish from the wall plus the price on them to build them versus having them built was little so I had them come pre built and tested.

Was talking to the "engineer"

Not sure why you'd test 3 generations, assuming the first two are blurple inferior lighting. Just curious what LED's were used for this testing.

This has been very informative for me reading these post @sparkygeek how would one go about building such lights and where is a good place to start?

I've been ripped off for the LED lights i purchased and would need to know wheres a good place to start in building my own

That’s what I wanted to know? What brand and such. Sure plenty of folks can knock the ole purple bandits. It there’s really good technology and it’s only getting better. What turns most people off is initial investment and don’t look at the roi which is important. Power cost and heating and cooling are only part of the equation. You have to take into account the lifespan of the light how many bulbs you’d have to buy in that span of time. Once a cob goes out they’re cheap to replace and bam you get another 50k+ hours on it.

In my post COB stands for Chip on Board... I'm not sure what you are talking about when you use the word COB but, I assure you, The LEDs are mounted on a "chip"... The manufacturer calls it a COB but maybe they don't know as much as you... I typically don't feed the trolls but they are clearly hungry...

Easy, guy. Goosfraba.

I'm just saying that no "real" COB producer is going to advertise their lights as being equivalent to double their output. It's not realistic, not yet. The most efficient current tech on the market are the Samsung and Bridgelux mid-power diodes, and even with those, it takes about six to seven hundred watts to equal an SE 1000.

Calm down, dude - for real. I read a couple of your other posts in which you were also seemingly unhinged about supposed "trolls". Perhaps people are just trying to set you straight???

Well yah it should throw a red flag when you see 1800watts and only pulling 300. Using 600 Watts to get comparable results or better than 1000 watter plus less heat is a win to me. Plus it’ll only get better. Also I agree the Samsung boards look nice I’ve been eyeballing some of those bridgelux strips though for a side project.

"They want to know what 3 lights I supposedly tested, must be trolls!"

Makes sense. Who would ever want to know the variables of said test that supposedly puts the proof in the pudding that LED just can't keep up.
