The best LED work is going on right here.
it is. that site is literally in the dark ages on information

not sure who's crunching numbers for you @sixstring2112, but anybody who comes to the conclusion that CXBs are nearly 50% more efficient than the competitors simply isn't using the provided data correctly. There's just no way to spin that, its straight up bad information. Also knowing what we know and expecting one brand of phosphor-based cob to act dramatically different than another manufacturer's of the same spectrum is really wishful thinking. photons are photons.

I didnt say anything about cree other than you guys keep quoting the prices at 50 bucks a chip lol.the comparison i referenced was shitizen and the new vero gen 7 and those numbers are here on this site using the same calc all you chipnerdz keep using haha.when's that video of you testing cobs coming ? Ya know with the lab coat and goofy hairnet lol.like i said show us how you use that sphere and I'll think about donating 1 of my dd bins so we can skew the numbers back the other way.nobody in shitizen land wants to see 200lpw @ 35w per cob,they just like the story about how cheap citi is and how great they work on cv drivers ;)

First Logic put me on turtle more for absolutely no reason, then he banned me for the same and invited me to join RIU.

So I did.

30,000 posts later I'm sure he's still regretting whatever 'logic' told him that was a good idea!

The best LED work is going on right here.
I dont think he misses you as much as you think lmao ;)

There's a lot more attitude here but there's also a lot more passion for the plant in all its myriad aspects. I'll take it!

not me. they havent been $50 for over a year now

can you link that? which citizen was used. theres obviously a lot of variables but even the cheapest of the clu048 are only 10% or less down in efficiency at low currents.. at a third to half the price.

when's that video of you testing cobs coming ? Ya know with the lab coat and goofy hairnet lol.like i said show us how you use that sphere
im about to do surgery on it so i can mount large active heatsinks for better data. right now im limited to about 80mm dia heatsink which i dont like

I'll think about donating 1 of my dd bins so we can skew the numbers back the other way.
assuming its 5000k 70cri, i have nothing to compare it with as i dont stock any of the low cri/high lumen/low ppf chips. if its 5000, 5700k, or 6500k 80 cri ill give it a spin

nobody in shitizen land wants to see 200lpw @ 35w per cob
lumens are for humans but im sure there are citi chips in that color that get there, no reason they wouldnt with similar phosphor/spectrum. if you tell us what color it is ill find a comparable citi color to run it against

they just like the story about how cheap citi is and how great they work on cv drivers
they work the same as any other cob on any driver, at half the price. sounds like a win to me

i gotta hand it to you six, you dish it out, and take it just as well. heres your first installment lol

Honestly I don't even need to see any growlogs of whatever new chip/led comes out provided the spectrum is given and close enough to identical colour temps.

I think you can safely trust the datasheets of lumiled/citiled/bridgelux/etc.

Ultimately those chips are all doing the same thing. Some just do it more efficiently and some can take higher temps better.
Spectrum is also pretty much the same so it's just about cost and efficiency

200 lpw at 35w sounds like a 70cri 5000k dd bin.

What would be the efficiency of cxb3590 3000k cb bin 36v running at 1.05 amps, there is no accurate info anywhere in the forum so I guesstimate 55%, is this a good guess. I wish I bought the 3500k cd bin it has 64% efficiency at 1.05 amps should have known the efficiency difference before I ordered them, stupid me.
Ordered mine from Jerry too very helpful and good service.
how much than for 12 cobs?pls tell me

Hey RIU I have been checking in from time to time. Have been keeping plenty busy renovating and had to battle some imported PM which I dare to say is finally eradicated. Still running the 3500K CXB3590s at 10-25W ea. Got a bunch of CD bin and a handful of DB bin going thanks to @REALSTYLES and Kingbrite. Getting 700-800 PPFD and have not needed to run AC except a few days last summer.

Lately I have been focusing on air rather than light though. Improving aeration for the soil mix and improving the circulation and exhaust/carbon fans. My GPW fell way off as the small amount of perlite in my mix eventually broke down and the granular DE was allowing too much water retention. Adding chunky perlite and Growstone GS-2 was an instant improvement in the ladie's health. The newest soil mix is 35-40% aeration and GPW is much better now 1.3 and hoping to get it much higher.

When it comes to fans I have been geeking out on the Sensda 8" DC inline fan on ebay and aliexpress. The Sensda looks identical to the Hyper Fan on the outside but they have different specs. The 8" Hyper fan draws about 80W at maximum (710 CFM) but can be run as low as 6W if your lights are dimmed or if it is winter etc. The 8" Sensda draws 50W at maximum (600 CFM) and can be run as low as 5W although Sensda recommended minimum is 15W.

I confirmed that the Sensda fan is what it says it is, a light weight, dimmable, multi phase EC, DC powered fan motor that kicks ass in terms of efficiency and maxes at about 50W. It is quiet and well balanced. Actually it is better balanced than my Hyper fan so now I know there was something slightly off about my Hyper Fan, but it has been working for more than a year non stop and doing its job using only 10W as @Greengenes707 once mentioned it could.

Since I am running the fans so low I could have just used the 6" or 4" version, but it is nice to know you have the extra cooling power if you need it for heat waves. Also using an oversized fan dimmed down helps keep noise to a minimum so I can study while I am working at night.

So I retired a $115 6" Can Fan Max Fan that was using 60-70W for a $140 8" Sensda using ~10W. I installed the 8" Sensda into a DiY carbon filter and I would like to try the 4" version for the veg/trimming/drying room carbon filter. The Max Fan was awesome but the Sensda DC fans are almost the same price.

For those who are solar powered, neither of the DC fan's power supplies are power factor corrected. Power factor is about .55. The Can Fan Max Fan 6" IS power factor corrected, .95-.97 pf. So if you ran an 8" Hyper Fan at half power (40W) versus a 6" Max Fan at full power (80W) they would draw the same amount of current and move about the same amount of air.

hi supra! good to see you.

im working on healthier roots this run myself

stupid PM! i always treat like i didnt get rid of it for an extra month after i think its gone. ive given up on taking new genetics in. between pm spider and russet mites its just gross out there
Watching GPW plummet and then shoot back up really highlighted for me just how important aeration can be. It made me re-appreciate something as simple as getting 2 zips per bucket LOL

Ya that imported PM was the most expensive lesson of my life but I am glad to have learned it. One thing I discovered during the process is that that H2O2 cannot eradicate PM in a perpetual. I did not think it would but I was hoping for a simple cure. Reluctantly I resorted to Myclobutanil (Immunox at Home Depot AKA Eagle 20) for the clones and 20% milk foliar to suppress it during veg. Havent seen any PM in several months but I will be keeping the 20% milk foliar going for a few more months just in case.

I have been very lucky regarding spider mites. Successfully eradicated them with Dyna Grow Neem oil in 2011-2012 and have not seen them indoors since. I saw Azamax work very well in a friend's setup.
