any info on the Evolve EV700 available

I find the pink to be quite the eyesore. I certainly wouldn't want to look in my grow space and see that every day.

rather just think pink

yes but easyer to make as theres only 2 types of led (3 colors)
so do you think its a "logharhymical" layout all the way along then or just at the ends

you could replicate these lights with some strips at various spectrum and drivers with dimming allowing you to control spectrum more easily. I designed my GG boards with two channels one of 5000K and one of 3500K so you can mix and dim easier. The same could be done various ways with strips or pcb's. You just need more drivers and more patience. Anyone can do it given time and effort.

I follow these guys on IG and other social media because their style is similar to mine.

Lol!
But it has too much blue for my taste! Half that much 6500°k diodes would have been enough. No question, it's a horny lamp, but it was not only made with regard to cannabis growing, its more for commercial crops.

do you happen to know if in a series parallel setup can i run odd number s of leds and get the same output to all leds ? ie 4/4/4/4/4/7/9 or will some groups be brighter than others ? all leds would be the same type
i didnt think you could ! you know about this type of thing dont you?

having a brain freeze moment lol

dose any one know is nichia does a 660nm red i cant find it on there web site

Nope! You can only use strings with the same voltage to create parallel circuits. Uneven voltage would result in uneven brightness or defect. To use your example it works only with 4/4/4/4/4/4/4/4/4 but there is no reason you could not mount the outer diodes tighter next to another.

You setup your series strings to establish voltage draw. You setup your parallel strings to establish your current draw. Current draw establishes diode current. The driver will establish the relationship between the diode string and the voltage. I like to use lower current drivers such as C1050B MW drivers to establish base current draw. To get 88mA diode draw with a C1050B driver 88mA/1050mA gives you 12 parallel strings. Fewer parallel strings gives you higher amperage or brighter diodes, so you can balance strings to equal current draw or brightness no matter the manufacturer.

on a electronic forum they recon that 124leds are running like "124=14S*8P{112} +1S*12P{12} =15S*2.74V=41V , 572mA max per board. The closer gapped outer LED must run at lower current for thermal reasons" so they recon the groups of clusters at the ends are running at a slightly smaller ma / brightness

There is no need to run the outer diodes lower. If so, the layout would be pointless because the teighter spaced diodes would provide less light which makes no sense. The PCB and heatsinks equalize the heat very well so it is not necessary to drive the outer diodes lower. Only if they get the same current the teighter spaced diodes provides more light to the sides and and optimize the distribution.
