Not in my experience.Ok so with this setup each is drawing 50 watts of actual power at the wall, so effectively i have 300 watts of led light and probably need 400 watts at least to replace the 600 watt hps right?

Do you passive cool or do you fan cool.I ran 4 at 50W each to cover a 2 x 3' spot.
No and no. They run super cooooool...Do you passive cool or do you fan cool.
How hot do they run
Do you use heat sinks at all?No and no. They run super cooooool...
They just be chillin'
You may need to invest in better ventilation rather than downgrade light in that space. 400 watts of cobs definitely should put off less heat initially than 400 watts of hps, but if you're area isn't properly exhausted/ventilated, 400 watts of heat is 400 watts of heat, and 300 will be less, but not by much.
What version of the hlg drivers do you have? You may just be able to dim them in the drivers. If not you could always add a pot to each panel to dim the current to the cobs.
This would be your cheapest bet.

No pins, no fins. But I do run one. And it's COLD. 50-55F.Do you use heat sinks at all?
I have dealt with a number of sellers on Ali-express/baba. I have alkso run my own small business where I had to process international shipments on a regular basis. The lower listed price on the invoice is what US customs cares about. it is the amount you will have to pay in duty and taxes for standard shipping. If you pay for the expedited (DHL) shipping then DHL handles all customs brokerage on your behalf. As well the "shipping" costs usually also include DHL's brokerage fee for the transaction. This is not all ways true be sure to check with DHL and your seller for exact details.For some reason they seem to prefer using DHL, maybe they feel insecure using China Post because they cannot guarantee the shipment. China Post shipments are still arriving quickly but as the holiday shopping increases I expect it will get slower and slower. The price on the invoice was not his cost it was marked that way for your benefit.
Hi Supra, I'm sorry to revive such an old post but I just started a run using 4 CXB 3590s CD bins in a 2x2x6 grow tent starting from seed (unknowns). They seem to love the light and I'm running @ 23w around 20" from the plants top.I am using diy reflectors in the veg room because the distance to canopy is greater ~10-12" and it made a noticeable improvement. I have a few diy reflectors and lenses in the flowering tents around the edges of the canopy but still experimenting with it and no clear idea the best approach for 23W COBs with such a short distance to canopy. Definitely on my to-do list.
Supra is loooooong gone, buddy.Hi Supra, I'm sorry to revive such an old post but I just started a run using 4 CXB 3590s CD bins in a 2x2x6 grow tent starting from seed (unknowns). They seem to love the light and I'm running @ 23w around 20" from the plants top.
I have 4 plants going, 1 is like 2 or 3 day seedling and the other are week-2 weeks old, I'm using bare cobs with no lenses.
Questions is, am I running too low a distance from the plants at this stage? I have an oscillating fan and they're all hooked to a Alpine Pro Rev. 2s with 120mm fans on top of them since I couldn't wire the CPU fans with the annoying PWM thing.
The driver is 1400A and is dimmed to its lowest ATM which if I understood correctly is 700ma so ~23w.
I first had them like 10" from the top, but raised them to Will's recommendation. I'm running 24/0 and wanted to see if there's anything I can do to maximize growth potential. The quickest bean to pop is around 11 days old (from sprout) 4" tall but has very tight internode length and is quite bushy compared to it being very short so I'm guessing she's liking it.. anyways, I'd love to hear your take on this..
Always good to know someone absent isnt for bad reasons!Supra is fine and just busy with life,I'm sure at some point he will pop in again from time to time,just chatted with him the other day.
Cap- Whatever happened with that GG girl you had flowering? I haven't seen that thread or update on it in a minute........?Supra is fine and just busy with life,I'm sure at some point he will pop in again from time to time,just chatted with him the other day.
Been very busy and a little tired of the trolls so I don't post much these days.Cap- Whatever happened with that GG girl you had flowering? I haven't seen that thread or update on it in a minute........?
I hear you on both accounts. Well I hope it turned out OK I was looking forward to those results. Just built my first DIY light and waiting on parts for 2 more.Been very busy and a little tired of the trolls so I don't post much these days.
Pics or it didn't happen lolPlants are kicking ass, running some new stuff along with the GG#4. The Sunshine #3 turned out great, just as powerful as GG#4 but only yields about 2/3 of what GG#4 does. Running some SeedPac stuff now, Chaos BX2,Chaos 4x4 and CunFusion.
Looks very happy and a lovely shade of greenChaos BX2 pic from Monday, day 22 of flower under 3590's. Plant went into flower about a foot tall.
