And you should see a doctor. They might be able to help that little sociopathic problem you have.

Projection as it pertains to psychology, have a nice read. Then go back to my previous post and follow that advice.
Very little faith in that you being a 'gro bro' will be able to work your way through that. So the running side bet is how many 'gro bros' would it take to figure it out.

Thanks to everyone for the input. Any recommended suppliers on 90 CRI rather than 97 CRI? Or 60 LED vs 120 LED density? I'd rather run strips every inch with lower density, than every two or four inches.
nfhiggs - 44" is a frustrating length for a 48"x96" fixture. Waveform lighting was helpful, but $99/16 ft strip is a steep price point when I need 12-24 strips per unit. That sale price actually beats most of their wholesale cost breaks, 10+ reels = $107.10, 30+ reels = $101 ..
Purplebuz - Attempted to contact Yuji calling a disconnected phone # and sending an email that came back undeliverable.
dabby duck - I'll take your recommendation on the flat bar if I choose strips.

44" Seems to me to be the perfect length - leaves two inches at each end for the frame. $99 for 16 feet is pretty competitive compared to Samsung strips, which are $27 each for the 44".

you could almost get away with running a strip of quantum boards between 44" strips but that would equal 97 inches because the qb boards are 9" wide one way.
on alibaba they make custom pcbs with the samsung diodes i have seen 800-900 count.
Or make the led panel 4x8

Not sure where your at with this project or the physics of it would even work but have your thought about using something like a thick piece of acrylic with High CRI small cobs or strips around the perimeter pointing in to the edge to make diffused even light?
I have some of these ceiling lights and the light quality is beautiful coming out of the frosted plastic with reflective surface behind it.

How many "gro bro's" does it take to change an led light bulb?
answer:.they never get it done... because they can't agree on how to water cool it
or which red's to add to "initiate flowering" or whether they are fake lm 561's
i know y'all can do better..[it's not 420 here yet and i went to Woodstock]<---nuff said
hint: it helps to use the word "troll" or even better "hater"
ps.my next one will use the word "sinner panel"

Nice project, but it seams like you haven't really thought about color quality which is VERY important for your case!
Xicato has some good papers on that topic.
High color quality LED series that I have tested: Xicato Vibrant V95 (3000K, just perfect), Xicato Beauty Series (2700K, perfect if you want a warmer atmosphere), Bridgelux Decor Ultra CRI97 (2700K, not much tested but first impression was... too yellow), Bridgelux Decor Class A (tested in 3500K, very good, too bad Digikey doesn't really stock them
), Citizen BBL CRI90 (3000K, also surprisingly good and cheap), Citizen Vivid Series Brilliant Type (3000K, just lighted up once, needs further testing), Lumileds 2835 with CrispColor (2700K - VERY good!).So for your case (mid power LEDs for stripes) I would recommend:
Xicato Linear Tape (with their Artist spectrum): http://www.xicato.com/sites/default/files/documents/DS XLT Artist Series 180202.pdf
Bridgelux EB Gen2 Series with Class A spectrum, don't know if they are available.
Custom made stripes with Lumileds CrispColor LEDs..... maybe Cutter has PCBs for 2835 LEDs and could reflow Lumileds to them...
that's too bad i guess they aren't doing so well
@AwkwardSeating - hi, lurker here...can you point me to the waveform product you refer to that's $99 per LED reel? I'm also looking into making a similar panel light with high CRI. I tried a similar project before and had some trouble with voltage drop. I'm hoping these "premium" versions have enough copper in them to withstand the high current levels.

Cut into 4' or short lengths and do not connect end to end to prevent voltage drop, instead use a distribution block.

For growing I am using Samsung F strips.
