some details on the lights would help
"2 1800 W cob leds" means nothing and im gonna go out on a limb and assume that you have a pair of cheap 300W lights sitting there

320 per light
with the efficiency of the epistar chips they mention youre probably looking at covering a 2'x3' per light so youd need at least 6 of those lights for your tent
dont feel dumb, the majority of the people on this forum (myself included) bought crappy LEDs at some point before coming here

if you cant return them for cash see if he will give you credit towards DE HPS or CMH, at least they will work for you - you want 4x315 CMH or 2 x 750 or 1000 DE HPS for that space
assuming he doesnt have any decent LEDs (or understanding of such) if those are the LEDs hes pushing
Most hydro shop owners put profit and margin ahead of happy customers and too many of them have zero knowledge of the products they rep.

From my perspective LEDs are confusing. To much technical talk for those of us that just want a light. Outlandish claims by most LED manufacturers and re sellers does not help. There really needs to be a standard set and agreed to.
People who work in hydro stores are generally under trained and under paid and have at best a basic understanding (no offence for those who are professional at their job) of everything, from lights to medium. Take anything they say with a healthy dose of salt.
GL with your set up.

there is.
every fixture can easily be quantified by two numbers
-Actual input watts
-PPF delivered
if your fixture manufacturer cant provide these, they are not worthy of your money

ahh.. I don't think a 300 w fixture should be sold as a 1800 w fixture or even marketed as a 1800 w fixture. The industry should set a standard.
if I'm looking at a 1000w HID..there all 1000w HID (give or take a few Watts).

those guys are crooks they give no shits about furthering the industry only making a quick buck
get a double ended not a single ended (30% more efficient and longer bulb life)
single ended HPS are obsolete
double ended HPS are almost obsolete

well once you guys get your act together and a set of standards then maybe they will be obsolete.
Some LEDs with heat would be nice for winter in my case......
LED tech has a way to go that's for sure and everything on the market today will be old hat in 24 months time.

my act as a supplier of well-characterized parts of known spec is together
reputable fixture manufacturers both on and off this site have their act together
unscrupulous companies who will gladly take your money and sell you equipment that will not do what they say, have always, and will always be around. In their minds, people still give them money, so act=together.
as far as HPS on an efficiency and cost of ownership as of today they cant compete with (high quality) LEDs and are losing more ground every year
LEDs with heat are called HPS
yes its always advancing. its already the best value on the market and only getting better and cheaper, and all of the HQ rigs build and sold from 2014-now will still be humming along at close to their original (better than HID) efficiency many years from now

You seem to be assuming I'm anti LED. I'm not at all.
I'm merely pointing out that the LED industry needs a standard so owners of them like the OP, and lets face it we see a thread like this every day get and understand what they are paying for.
I'm not sure why this puts you onto the old HID VS LED debate. Just for the record I agree LED are superior to HID in most applications. I'm waiting for some strips to arrive so I can build a veg light. I will be looking at a summer flower LED light in the future. Some interesting new fixtures becoming available soon like the Hortilux 240R.
But ill say it again, its time the LED industry developed and stuck by a standard like the HID industry has.

there is a standard as i explained
unscrupulous vendors will never use it because facts make their lights look bad.
its really that simple. you cant force those companies to be ethical, they dont care.
the only reason they have is because of bulb availability. the majority of the bulbs used from the 70s up until at least 2000 were garden variety high bay bulbs by philips, etc. Even hortilux had to make sure they were standard to fit all the fixtures out there
LED = no bulb replacement = no need for standard equipment
again watts and ppf is all you need
just like with hps, watts and lumens were what was specd (but all 1000W just happened to be similar because they used the same bulbs)
with LED, depending on what the manufacturer selects for emitters and how hard they are driven, you can literally have a 1000W fixture that is twice as efficient as another.
LED industry tried to use the "equivalent to HPS" wattage, which was a disaster. Example: OP's lights.
PPF is PPF and if its real its a good yardstick
"HPS equivalent wattage"
"PPFD at xx inches"
"covers xx square feet"
are pretty much all bullshit useless arbitrary measurements

Yes and we will keep seeing those thread for years just because of the price of those cheap led. They are very attractive to new grower without much experience/knowledge. When you search forums and articles for best LED you find tons of sites stating That Mars hydro is very good or bestva or wtv name they can have are the best leds on the market.. this is also the reason why most "older" hps grower fears so much the LED because of all the false claims we heard in the past few years.. we are seeing more and more companies using real cree/vero cob or lm561c led or strips on their light which is a good sign for the industry but they are priced 3-4-5-6 or more times than other chinese blurple led light at the same "advertised wattage".. its easy to get confuse for anyone who hasnt made research on a forum like this one..
And finally in 2 yrs from now i dont expect current systems to be obsolete.. we know that samsung is already producing a better efficient led than the lm561c but beyond that I didnt heard anything coming up. We know for sure that some led manufacturer are able to create more efficient led in labotary condition but will take time before they can produce such unit for consumer use - and also at what price point and how more efficient will they be. I dont think companies like samsung are limited in terms of fundings but it also goes hand in hand with demand and home or even commercial grower arent necessarly the target consumer of those LED. It is most often then not big offices. So when big building in big cities will move more and more towards led (many still use fluorescent light) it should drive the price down as well a new innovation up.. we will see cant predict the future but id say I think it will take a good 3-5 years at least before we see a new led that will be worth to switch from the current available good quality and efficient led. But thats just my opinion lol
