i just want to say how impressive this thread is..there is no way i want to diy leds so i have got a couple factories

you know where ..to make me bars[lettuce], panels[or fun], and highbay[excited] with several different custom spectrums..so i can

test them first hand..cree, bridgelux, and epi..[yeh i know]...

all i have going now is the epi panel and it is doing good job on my vietnamese clone.

i looked at cobs..maybe next time..

tests with blues reds and whites, various wattages, beam angles

leds are as addictive as sushi

thankyou

oh so let me throw this math out for everybody that just loves to do math. 8- CXB3590 3500K 36v on a HLG-185Hc700 in a 4x4 into PPFD

CXB3590 3500K @ 1.4A = ~49W and 56.3% efficiency
So 8 of them = 392 dissipation W * .563 = 221 PAR W
221 * .85 wall losses = 188 PAR W
188/16ft² = 11.7 PAR W/ft²
11.7 * 4.65umol/s/W * 10.7 = 583 PPFD averaged[/QUOTE]

About half of that... 290ish ppfd

Nice, so you just said about half that cause the quote was 1.4a and i'm using .7a?
That's great cause i'm about to double up that same unit and if it puts me around 500 (just to cover half the tent) then next i'll copy that panel and have ~1000 in a 4x4 to bring me up to PAR (haa oh so punny)

You're going to want more COBs than that for your discs. I'm running 4 CXB3590 at 50W for each 2x3' section of my trellis, for 824 PPfd. Thus, you'd want four of these setups for your area to get the same lighting.

Dividing by 2 is very wrong, if that were right, there wouldn't be any advantage in underdriving ...
In this case there is 10% more light than your guestimate :

@64%
(8 ) CXB3590 3500K CD @ 700mA (23W ea) $380
(1) HLG-185H-C700 $65
184 dissipation W ->66W heat ->

117.8 PAR W covering 16ft² / 1.44m² = ~380 PPFD (not accounting for any losses)

323ppfd using 15% "wall losses", as supra's does ..

Conclusion is similar tho : not enough power, you'll need to double (or more) the amount of cobs to flower in decent conditions in a 4x4 ..

“Buy quality and cry once— buy cheap and cry forever”

You pays your money and you takes your chances. After you get tired of screwing around with the crap, you will eventually end up with Cree COBs.

It is like the Filson Motto – “Might as well have the best”. You screw around and buy second rate trying to save a few bucks and because the stuff is second rate it does not perform up to expectations so then you go ahead and get the good stuff. In the end it costs more, because you bought the junk and the good stuff. It also wastes time and time is the most precious of all, because it cannot be bought or replaced.

If you can use a drill and a screwdriver and follow a cookbook recipe, you can build your own COB light very easily. Read some of SupraSPL's suggestions for a good light, heatsink, fan and driver, LED driver and use a holder to hold the COB down or just use tape like SupraSPL shows, plug that sucker in and light up the world.

Check out Realstyles threads. He knew very little about COBs and LEDs, but he asked SupraSPL what the best stuff was and when he got his answer, he put his light together. Once he had it figured out, he just kept on building one high quality, high output light after another, each a little better than the previous version.

I hope that helps.

well, for an average of only about ten posts a year, he definitely makes 'em count!

as i can not diy, and would prefer to buy a plug n play led,, what would be the recomendation for my 4x6 table? one larger or a few smaller led's?


any thoughts on a couple G8LED 450 WATT
LED Grow Light for Flowering BLOOM with Optimal 8-Band with Increased Red Spectra and Ultraviolet (UV) - 3 Watt Chips

THEY ARE 600.00 A PIECE,,2 should cover my 4x6 table correct??

or

Advanced Platinum Series P300 300w 12-band LED Grow Light - DUAL VEG/FLOWER FULL SPECTRUM
this one is 374.66 a piece once again id need 2 to cover my table..

id like the advanced as it would be cheaper,,,thoughts? recomendations? or a link to a good led at amazon would be really appreciated!!!

Stay away from Pled and G8led cheap quality and lower efficiency, lower than hps.

Some updates from the CXB tents. 46 days of 12/12, canopy air temp during lights on ~75F. Mostly 3500K CXB3590s at 25W ea, ~750 PPFD in every part of the 5'X5'. Definitely some fatties in this batch. This is the last batch of partial no-till. I just loaded each bucket up with EWC during transplanting. Some of them faded early but still looks like it will be a good turnout.

TGA - Qush (Pre 98 Bubba X Querkle)

Cali Connection - Grape OG (Tahoe OG Kush X Romulan Grapefruit reversed) This lady is over 5 feet tall including bucket

There are 3 ladies in this run from TH Seeds - Ultra Sour (Mk-Ultra x East Coast Sour D) They are all very frosty and golf ball style dense nugs, fast finishing they are almost done already. One is very earthy, one is earthy/fuel/flammable and the other is sweet/fuel/flammable. Will get pics of them soon. Looks like another big thumbs up for TH Seeds fem beans.

That proves it, LED lights just cant produce big buds.

No, but really though those look awesome, and 5 yrs ago, I would never have expected that LED lights could produce buds like that!
Those girls look amazing, Great job!!
