Chinese -Leds

Lets break this apart.
China, means from China, aka Made in China. Where are Cree LEDs made? China. that isn't retarded, that is fact.
LED, means light emitting diode. Check there too.

So Cree LEDs are factually and correctly Chinese LEDs.
Crees are desgined and overseen by creeUSA. That is why their product is consisstantly ahead and leading the pack no matter where they decide to MANUFACTURE...but they are not "china lights". Learn the context of the term. If you had been around longer than dec 6th 2014 you might actually know what it means in context.
Once again you show you education...or lack of.
I wish someone would do a fair side by side. Anyone want to borrow me a 1000w Cree setup for a few months?

I would love to do 1200w of my epistar leds up against 1000w of crees.
Sack up and do it your self or shut the fuck up. You think your right??...prove it by your self big boy...no mommies holding your hands.

Real quality companies have no need to show up a piece of shit light...the numbers do that.
The only concern for a real quality company is HPS...the reigning king and what EVERYONE IS TRYING TO REPLACE. There are not warehouses full of apollos they are trying to get the facility to replace...they are trying to get them to take down 1k hps...and that is the gaol to beat. And what the few side by sides have been Or top products vs top product like capts a51 vs onyx.

I don't run a big operation so it's not the best example, but I hardly see a change in my electric bill running MH / HPS, and I'm fairly certain any comparable LED would be outside of my comfort zone budget wise so the increase in 'efficiency' wouldn't negate that additional cost up front in my situation...the 'cheap chinese LEDs' probably can't compare so I'ma just stick with MH / HPS for now...got a cheap LED panel in my clone tent but I could prolly get by w/ a cheap T5 fixture as well. BTW I'm pretty sure all of this shit is made in China lol. I think a bigger factor than being manufactured in China would be which company is outsourcing it to China ;)

You guys need to separate two things in your mind. The LEDs themselves and the assembly/electronics. Most of the quality issues are not with the LEDs, they are with the assembly quality/electronics. That is what gives the epistars a bad name. I don't recommend anyone buy LED fixtures that aren't getting good reviews, or LED fixtures at all really. I only support LEDs on a DIY basis (or LED bulbs as a CFL alternative for single plant newb grows.) Non-DIY LED is a ripoff for the price regardless of the LEDs used.

See that's why I stay away from em...Just from a speculative perspective, everyone I've seen that's having good results with LED is either running a DIY system or spent too much lol. I don't want to do either. Don't have the time to become an electrician, n I waste enough money as it is.

I think @az2000 hit a good point tho - the generic led panels are gonna be a lot more bang for your buck than the generic panels with a logo slapped on them lol.

Hgrow may have been beating a dead horse...but it was a real horse at least. And he knew what he was fighting against regardless of his antics and redundancy of it...when it was just educated growers around here it was annoying...now days this thread seems it could have some use...

Everything fails in the cheap units...drivers, fans and DIODES...

More bang for the buck in terms of short-term costs. Long-term, no. In a taller grow they won't produce as much. Won't last as long. Will consume more electricity. At $200 that's not a lot to put at risk. (The rebranded epi-whatever fixtures are a different matter. They seem predatory.).

Check out the LED "lightbulbs." That might be a good way to scale into LEDs without spending a lot up front, and without going the cheap epi-whatever route. They're in the 100 lm/w range, slightly better than T5HO.

It almost never comes down to the diodes failing for no reason. If they fail it's usually still a driver issue or they weren't connected to a heat sink properly (assembly issues).

And you should really stop with the baseless insults and accusations BTW.

Give it another year or two and none of this will matter anymore

Cree already has a lot of nice commercial lighting..their just a few steps away from having a drop in HID replacement that runs cool enough in a enclosed space

For example..

That is the best advice, if you can't DIY, wait a couple of years before going LED. They are getting close to where they need to be, add a few more advances and some time for the prices to drop and they will be the best/only option for growing, right now, they are a sucky option short of DIY or vertically short spaces.

You are yet to show or prove anything. You chime into every thread and spew shit as if you have ever used it. You say we haven't used crap units...well most of us have.
You on the other hand have yet to use quality and are talking out your ass.

Well, I guess I'm not stupid enough to buy a crap unit, so sue me. I don't have pics of the 1200w setup running at the old place. The best I can show you is what I posted here: https://www.rollitup.org/t/if-you-are-new-to-led-and-want-help-choosing-what-to-buy-post-here.633304/page-236

I'm sure you will have some snide comment, but they are doing quite well under my epistars.

I still want to see PAR comparisons. I think a lot of people say LED is worse because they're comparing a 600 watt hps to a 600 watt LED that only draws 250. I also don't buy the white LED theory, yes I understand in sunlight that green is used up much more than a photosynthesis chart shows because it continuously reflects off the surfaces... But LEDs don't have that kind of power to travel those distances. Ditto with the carotenoids absorbing green behind the chlorophyll and passing excess energy to the plant.

You can get more penetration with 5watt LEDs but they're less efficient so only worth the cost in large scale grows. Just go 3 Watt and do a scrog or sog, probably still need a/c but you can get them closer than hps and get better light distribution.

If you're all so worried about efficiency why the hell are a majority of the diy led grows in dirt? Don't tell me it tastes different, all the plant uses is atoms that are made of elements which are ultimately the same from salts as from molasses or poop, you just need to get the ratio right.

If you want to compare quality of lights run the same watts in the same room with mylar reflectors between lights with co2 and the same techniques in hydro on clones from the same mother, you gotta look at veg time too. No fair trying to grow large trees cause hps will win if you're looking for efficiency then flower clones from root in a sog.

I already saw you little autos...I actually research before opening my mouth.
Not bad for autos and/or a guy in the middle of no safe access(illegal closet grow)...but sure not winning any cups or in high demand from a dispensary. Or going to make me shit myself an want to convert my op to those lights.

Even without pics or documentation...you got an average g/w...or for you since you don't like that...g/sqft???What were your yields...what strain(s)...space...setup...
What were you doing that should/would make others see that your lights are the best or are at least as good as cxa's???

Testing same watts against same watts is a test of efficiency and target spectrum. If you want to test just quality/output you need to size both systems to ideal output, input shouldn't be considered.

Nothing. I haven't seen anything showing Cree are better from anyone either though. We need a side by side. So either a Cree user has to bite the bullet to backup their claims or I have to buy a cree system to backup mine by your logic. Well it's a cheaper investment for you to buy an epistar system, so get to it if you want to talk shit like you are.

Guys, come on, let's just pray to God to give us the answer and ultimate lighting system. Ask and you shall receive, in Jesus name, amen. </sarcasm>

The way I see it is you've got to pick a side and just have faith in the spirits of your lighting system, because as of now the evidence you're presenting is about as compelling as the Holy trinity.

It tastes different...:-P

Not to mention zero runoff.
Have you done a side by side? I haven't done one with soil vs hydro on weed yet, but last summer I did one with a burpee "patio" type pair of tomato plants. They taste almost identical, if anything the hydro (maxigro/maxibloom nutes) had a slight edge. Once the new room is up and running I'm going to do 2 soil plants right inside the door to compare with the rest being hydro.
