@end_of_the_tunnel yeah, i can paly a bit with the air distribution.
its not soo uneaven atm and shouldnt cause problems but can be, idk.
but again this plant looked strange from the beginning.
@Bignutes
youre right a higher temparature would help.
its just winter here and i am not willing to heat with electricity.
a warmer seanson will solve this problem.
to which thermal youre refering? from which version.
i guess youre refering to V1 where the outer strip is laying on a t-slot over its whole lenght while the others arent.
your interpretaion is probably wrong you need to consider where the frame interacts as heatsink, where is more material and where it dont, where is more airflow etc.
i eaxamined my thermals regarding this closely and took many life readings as i checked the radiation uniformity with the spectromaster.
if youre right you would be able to see 4 groups behaving similar.
would assume ill have a more uneaven load distribution if using more in parallel, simply the nature of the beast.
consider that the load is very low also, 525mA, in real world now 300mA.
i can see if can do a a more clear thermal for you.
yes below 60v is low voltage, there is CE on the strip so they better write that when selling a bare board.
the solder stop can take, as any other at least 1KV, connector n cables are rated accoridngly, am using a extra GFCI etc.
anyone to his liking.
i have my driver remote and dont wanna loose so many watts on the cabling.
also when i concepted it there where no xlg line out as the new AB driver versions.
i took also nylon wahsers, which you should do anyway.
consider that the load is very low.
below attached 2 screens of what a trace needs to be for 525mA, 0,06mm and its for sure thicker on the eb3 strips.
also 2 voltage drop calcs for 153 and 44V, well it isnt a world.
did strip layout logarithmic, as good i can to avoid the hotspot, there are real world limitations, especially the size of my custom strips who should fit in between the EB3´s.
there is always room for tweaking, but the spread is dam good.
i payed 28$ for 6x 780mm and 2x 800mm t-slot bars, incl. precise cut, no shipping, no mounting material.
ill pay 8.80$ in my next homedepot for 2m suqare 20x20 aluminium, no cut, no shipping, no mounting material.
buying regular aluminium online puts me in a similar region as the t-slot.
in the end i safe on tools and nerves, have no metal workshop at hand.
why should i bother for alternatives?
edit: first i understood you, i ,should look for a alternative, could be you edited this part.
"threaded rod thru aluminum angle " is for sure a usefull searchterm, i would investigate if i need to for sure, good hint!
i ve read some about positive effect of using 365 and 730 together, ill may try that.
i just wont be able to interpret anything if i change too much at once now.
only fear i have there is that the 730nm will reach below the canopy while the UV wont.
