$229 for 800w LED.....how bad can it be?

[Rocket Soul]

Lol..I had noticed the AOKAIRUISI lights...the diode count leads me to believe they are overdriving them to get the par, but just buy bigger than needed and run it at 75%....interesting light. The Wantye did ok at veg...it's a better flower light though...for the money it's well worth it.

The other issue is amount of bars: the one you use has 8 bars while the aokairuisi runs 6: not only will the diodes run harder but also the sinking is going to be hotter which makes environment harder to control but also makes the light more likely to fail sooner.
There are many ways to save a few bucks but generally you get what you pay for. Maybe not worth it going for the absolute cheapest option, unless youre going to underdrive it considerably, as you said.

Little over $200 for a 700w light....I have a 500w from them that works fantastic.

End week 5 on Blue Dreams. 5 gallon BD ahead 7 gallon by at least week but smaller buds. C99s in front at the start of week 3. I just unscrogged due to them trying take over whole tent, lol.

 

[UGDoCV]

Start week 8. Smaller gallon BD ahead of larger one. These sure do smell funky and different.

 

[UGDoCV]

Trich shots for BD mid week 8. Could probably chop the smaller one at this point, but.... no hurry.

Dude them are frosty as hell!

2nd, BD. Gonna chop when dries out a bit more. Will be 11 weeks flower.

Overall pleased with light and results. It's ran nonstop since purchase and for now everything is harvested. Gonna shut down till after holidays if I can wait that long, lol. Tents gonna get a thorough clean, then gonna play with some autos under this light. Had add a pic of something, lol. Finishing up cold extraction today.

Same here....several grows under it now with auto's and photo vegging and no complaints at all. I did add the Mars uv45 bars to mine and very pleased with them also.

All who got the 800w LED from the 1st post is it still 100% working..
Mine is still 100% ..

Mine never gets above 75%...usually runs lower around 550w. Coverage is pretty good...not as good as my new fc8000..but pretty damn good.
All diodes still work and still draws 815w on 100%

 

[Hammerhead]

Is your light still working 100% with no defects is what I meant.

 

[driver77]

I didn't mean how much power was used.. Is your light still working 100% with no defects?.

yep...like I said at end of last post...all diodes still working and still draws 814w on 100%.
Only issue I had was the hinges letting the light bow up...stuck some folded up paper in between and good to go.

 

[Hammerhead]

Thast 2 of us.. Anyone else?. I'm curious about the defect rate vs price. I was expecting to see diodes fail or other issues with such a cheap product.

 

[UGDoCV]

Mine is same outside of what I listed early on. I did shut down for Holiday but ran continuously since purchase with no dropoff. Will start back up January.

Looks like these were a good buy, and perhaps one that won't be repeated.

A bit like the latest cpu or phone, buying the best LED isn't cheap. We can only do so, when we look at the power saving over the life of the light. If we want instant gratification, then buying the best LED isn't the way. We could never sell a domestic lamp with an LM301 inside. There is always a much cheaper option, from a lesser known brand that's just a year or two behind. Our problem is, that we don't recognise the wheat from the chaff, unless it's the top brands. It seems these were the wheat.
It's not just the LED, but the driver where there can be big price differences. In theory, stringing about 50 3v LEDs in series, yuo could run almost directly off the 120v mains. The driver, would cost cents. On the other hand a good one is over $50, and one that just works, $10. However, the $50 one spent $40 on not knocking out the local internet. It's not a saving worth making. Yet, you may never know the difference, unless you are unlucky.

It looks like you did well here, and I feel almost jealous I didn't snag one myself. Though it would of been as a gift, after checking for those spurious emissions, that cheap electronic ballasts are known for. Especially if you were to start extending cables.

A variety of haze and Kush hybrids.

I need new LED setup, what are the best full spectrum LED’s available today? Last time I grew, few years ago, it was COB’s that were the best. CREE something or other, still have them but looking to upgrade.

SAMSUNG DIODES
I have 6 COBS CREE 3590 ??? id like to dump JUST REWORKED THEM AND THE DRIVERS IN A NEW GRID
Mars hydro is nice $$$ triple digits but you prob save that in electric

SHOULD HAVE GOT THE 730 WATT
THE 480 was in my price range currently and its decent so I cant complain
and ask @Mars Hydro Led see if he can send you a ICfam discount code
