SDS, I want to incorporate an EMI/RFI filter into my control box which will house 2 Meanwell HLG-185H-C1050As, and a Meanwell RS-25 12V DC PSU. I am not sure which parameters are important, or if there are any brands to avoid. I would imagine I am looking for a low leakage current. If you...

If it has to be meanwell, then the H LG -6 0 H - C350. It will run 8 of those. This is the only low power, high voltage meanwell option that I know of. A version for internal pot adjustment (210 - 350ma) B version for PWM/10V dimming Inventronics offers some larger wattage options with...

The clarification is mucho appreciated! Have you had a run before without the complete line and just the base nutrients? Has the complexity and added cost been worth it in your grows? I personally aim to keep things as simple as possible, but then again, you're the one pulling 1.1 g/w! :weed:

Correct, the Nova products do have the all the trace elements in them already so there is no need for a micro. They do have a 1 year best before date however. That, coupled with the intense mixing required (think a really thick fudge sauce like quality), precipitated the switch for me. The...

Curious about this as well as I am going to be switching over to perlite and promix bx in 5 gallon hempys to make my life easier. Your results are hard to argue with! I also use the 3 part gh flora series. As I understand it, both these media a basically inert. If you don't mind, what are...

500W emanating from 13 cm2 would be quite the sight... at least for the fraction of a second before your retina explodes. :lol: Wow, what a beast! :clap:

This is likely very true, not because of the hoops you jump through, but due to my novice gardening skills. We've all seen those girls of yours :bigjoint: I'll likely be running into the 8 kwh/g barrier come harvest in the next week or two, but I knew this would happen - it was just a single...

Right before you posted the reply above I had the "Ahhhhhaaaa!" moment. I was under the belief that umol/s were independent of the radiometric efficiency which is why I was applying a correction factor. Your last post reinforced my understanding of the concepts at play and set me straight, so...

Sorry Supra, I deleted my post because I replied before your edit. Hmmm, I definitely have some more reading to do then! It would appear that my reasoning was incorrect, although I don't completely understand why. Off to wiki! Sincerely appreciate the replies, as I'm sure many others will.

That is such a fantastic improvement. I'm sure you'll bust right throw the 1 g/w on your next run! Super impressed! What is your g/kwh looking like?

This is a very interesting question. Mr Flux posted this; CXA 3000K Power in : 3.8 W Luminous flux : 423 lumen Efficacy : 111 lumen/W LER : 344 lumen/W Radiometric eff.: 32.3% Radiant flux : 1.23 W Photon flux : 5.98 umol/s Blue : 10% power, 8% flux Red : 24% power, 27% flux My interpretation...

Thanks I did manage to find that after some more digging, I was just heading back here to edit my post. I'm still a bit confused as they list a zhaga 3 holder for the cxa3070, which is spec'd for a maximum diameter LES of 23mm (which matches the cree), but cree lists 25mm to the edges of the...

Looks very promising for an off the shelf solution. If only they published the tapped hole spacing options. I'm not particularly interested in going through the spec sheets of all the compatible cobs in order to see if there are any holes spaced at 35mm that would fit the ideal cxa 30XX cob...

grnlife - nice to have you here answering questions. If I may - There seems to be some confusion on the specs of your products according to the product sheets http://innoledinc.com/product-sheets/ and the descriptions listed on other pages. Can you provide us with the correct specs of your...

For 10 cxa3070 3000k z4 in a 4x4 I get; - 707.24 PPFD @ 1.05A - 817.54 PPFD @ 1.40A When deciding what multiple to run, it's best to start at the driver level IMO. If you will run individual drivers for each COB then this is a moot point. The highest efficiency choice that's been tested in...

I would personally go with a Meanwell NES or RS 15/25 12V. If you do use the PC power supply, and 12V is too loud, and 5V is too soft, you can get 7V (12, 5), 8.7 (12, 3.3) or 10V (5, 5) out of a PC power supply very easily. Not that you'd want it for a fan, but you can even get 17V or 24V out...

You don't need to 'cap' it; it's a constant current driver. The LED will only take the voltage it needs dependent on its temperature at 1400 ma. Why not go 3070 though? 3590 just doesn't seem worth it given the current pricing and lack of suitable drivers IMO.

That point in time is already here. Quality LEDs and the associated build components are currently cheap enough while hydro prices are forecast to rise 200% over the next decade or so. You simply refuse to understand the merits of maximizing system efficiency through using quality gear to...

I may be wrong but I believe Pet mentioned somewhere that the website hasn't been updated with the new bin parameters and it is effecting the projected efficiency.

Bucks need a higher voltage than the conversion by about 3V. You wouldn't be able to run a buck for a Cree off a 12V PSU. I'm not familiar with the vf of the chinese COBs you mentioned wanting to use. I doubt they are under 9.8 volts though (average PC PSU seems to be about 12.8 volts). If...
