Wow ! Those are what call great figures ! :clap::clap::clap::clap::clap: You did a fine job takin' care of the cooling ,brother ... Reall fuckin' great job ,indeed ...:hump: Cheers. :peace:

Brother Fran I really like Chip Scale Package LEDs myself ,too ... Although I do have some second thoughts about 'em ..have to admit that .. One of them is the small sized LEs as you 've mentioned already . From my point of view I do not actually see it as an " advantage " .. On the contrary...

That 's the reason I do not use pots anymore ... Instead I use a 6 position rotary switch with 5 resistors .. At the max (rotary switch at 6th /last position ) nothing is connected to the switch and the DIm inputs of the driver... Cheers.

I think Xitanium drivers have a case made of plastic ,ain't that so ? Well ,if the drivers are remote and the driver's output voltage is not higher than 50-60 volts , then no earthing / grounding is quite acceptable . cheers.

RTFR (Read The Fuckin' Report* ) Almost all " 3in1 dimming" LED drivers from MeanWell do output more than the rated output current ... Absolutely normal ,when you run the driver(s) with open (not connected ) the Dim+ / Dim- .... * Top left between "Spec " & "Certificate" at the product...

???? Relative spectral distribution chart with a peak higher than 100% ? What kind of relative is that ? Relative to what ? :-?

Brother Guod ,I wanted to ask something to you ... Is there any evidence that higher green plants ( like mj ,for example ) do have Chlorophylls D & F (far red Chlorophylls ) ? Or they are present only in marine plantae kingdom ,like red algae and cyanobacteria ? Do you have any info / links ?

Well,I did digitize the RSPD of the CXB3590 30006K 90Ra to doublecheck the figures ... So..The BD bin @ Tc=25 C and @ 1.4 A gives these numbers at the spreadsheet : LER : 276 Rad.Efficiency : 51,9% Power Dis. : 48,776 W lm/W : 143,42 PPF : 124,41 umols/sec Mass of CO2 fixed in 12 hours ...

Thanx,bro... I've used values of PCT at 25°C for the CXB3590 ... Still I've one question . The CXB3590 has the same VF for 1.4 and 2 A (being 34.84 V ) ? :P ( @2A isn't it 35.93 V ? ) Anyway ,,I did not expect a PP efficiency of 70% .. I was hopping that it would 've been greater than of the...

@alesh Brother ,'cause right now i'm pretty bored and tired to digitize the RSPD of the CXB3590 3000°K 90-92 Ra ,bin BD ( CXB3590-0000-000N0UBD30x ) I was wondering ... Maybe you can do the dirty job and then supply us with the CO2 fixation results ... ( at 1400 mA & 2000mA ) :P... I can do...

And a comparison ..... Cree CXB 3590 3000°K 80Ra 36V type,bin CB versus Bridgelux Vero 29 version 1.2 (old model ) 3000°K 80Ra . At 2 A driving current ,for 12 hour light duration : Cree CXB 3590 3000°K 80Ra 36V CB Dis.Power : 71.86 W Lm/W : 144.073 CO2 grams fixed : 21.66 Volume of...

Well... I'm not able to go to sleep ,tonight ... So -just for the fun of it- made a new tool ... A spreadsheet that calculates how many grams of CO2 your plant(s) fix per light cycle . How it works : Basically it multiplies the RQE McCree curve with the Cannabis L. Sativa absorptance...

Fran ,it's not just me saying this ... My previous job had something to do with aviation ... (In case of someone asking this : Yes ,I can fly some types of aircrafts ,but not when I'm ...high ! :P ) (...)CPP measurements showed that the presence of Gr and the increase of its content with...

BTW ...I'm not quite sure if this the appropriate thread to post this ,but what the heck ... I'm gonna do it ... Maybe it will be a bit of help for the FCO team .... I've multiplied the McCree curve ( aka "Photosynthesis Action Spectrum ) with the Absorptance curve of Cannabis Sativa species...

Cree uses ceramic material for casing it's COBs. Since ceramic is non electrical conductive , there's no issue about graphite and galvanic corrosion . A copper heat sink can be used with ceramic COBs and graphite TIM . A ceramic heat sink also can be used . But an aluminium heat sink remains...

(...)The use of graphite is limited by its tendency to facilitate pitting corrosion in some stainless steel,[17][18] and to promote galvanic corrosion between dissimilar metals (due to its electrical conductivity). It is also corrosive to aluminium in the presence of moisture. For this reason...

I can't really see " Super incandescent " on the horizon ... What i trust will happen with that new advancement, is the birth of the "thermophotovoltaic" solar cell ...
