beautiful work SDS :), Dedication - your commitment has shown nothing but :D. Making dreams reality!

Great looking build there Positivity :). Nice integration of the components in a pro looking package!

ffs sds... last time I read about your LED quest you were disheartened and said you would probably just end up buying another chinese panel if you were to go through it all again... I'm glad you got the fire back for the LED world and you continue to take things to the next level :).

Kandy Kush macro looks lovely mate!

Currently experiencing total ignorance from SOS including the phone being put down on me. Payment cleared on day of order and no updates since... and in fact I am very pissed off with the service they have provided having taken my money and done a runner it seems via BT. Hope they prove me wrong.

Your panel looks like it did a great job mate! :). Can't wait till I can afford to buy some LED's to try. Got some plans laid out but I did discount far reds... though reading recently I am seeing the science in pr/pfr and how adding them at the end of a light cycle could allow for longer...

Pricing for 20 panels 40 * cree cool white XM-L2 U2 1C (CW) 6500K (£3.90 * 40) - £156 XM-L2 U2 cool white is available from illumination supply on copper pad.That is the most efficient LED that has ever hit the market (57% efficient at 700mA 50c)...

Hmmmm... in an effort to try and even things up (although I don't think I really have... :D)... I ended up copying almost identically the Grow Northern Luxeon layout for a 30 led modular setup... I've ended up making a 30 LED panel but I think i'd have to copy the grow northern layout and...

Would you care to stop by my thread SDS sometime and take a look? So much is probably wrong... but is it even feasible? :D.

Arranged somewhat, not exactly sure on what reds to go where yet... hopefully they can be divided up more evenly than the 23 of each cool white and blues :( lol. I had to be creative in figuring out where to put them... out of balance ever so slightly but it will have to do. Could I now...

24*16" Ok so doing some math i've managed to get so many numbers of rows... unfortunately i'm not sure where i'm exactly going to put what wavelengths where but here we go. 368 LED Panel Intense grow area focusing strategy: Aim for deep reds in center blues immediately surrounding in a...

And if we take away say the oslon red and philips lumileds we have a panel suitable for both modes of veg/flower running 174 leds less. The spectrum then also looks very similar to Guod's markaber spectrum with slightly less green and yellows. Although it may be beneficial to run ssl150's...

So my first mockup regarding chips and a general rough overview from what my little diagrams tell me (again may be totally wrong :D). Doesn't look like it'd going to be cheap either haha. I've tried to include the best of all worlds although to replicate some spectrums I've had to go for less...

Todays reading: Well i've been playing more with a spectrum tool (http://www.1023world.net/diy/spectra/) for specific chips and tried to build up a few of the designs on there to compare spectral output at a few levels... also gives us an idea of umols... not sure I got the right chips for the...

Thank you stardustsailor for your input :) and nice tune, sounds like a funky chiptune from an app crack :D lol. I suppose i'll start playing on http://www.1023world.net/diy/spectra/ and see what I can come up with in regards to what quantities of lights I might try!

Lovely looking plants, I've been wanting to see an x5 spectrum grow for a while :D. Subbed up.

Cheers smokey the cat... and thanks because I had meant to of mentioned the makersled fitment here after seeing it last nightand screenshotting it on my phone... Damn I need to sleep soon almost light outside lol. Just reading through another Stardustsailor thread at the moment, time to roll...

I've not etched any PCB's since uni a few years back, thinking it may be time to relearn how :D. Stardustsailor... what are your current thoughts on 660nm/far red LED's? I read a little about pr/pfr and its quite confusing... are they as damaging as first thought?

And here is Supra SPL's kind of equivalent spectral graph... somewhere between these images below... The make up is as below: Check it out here.

I really like your ratio/numbers of LED's on each module, I see a large bump in the deep red ratio compared to other panel arrays whilst still hitting a little of that green and yellow area (from a guess, but not comparison individual chip data :( lol.). I've added it to my thread ish... as much...
