modular overkill led striplight build

[cobshopgrow]

@Rocket Soul , hey man, hope you enjoy your holliday
just meassured with a ruler
the spectromaster in the picture above should be about 11" away from the light.

regarding light green, yes thats tricky.
uv could be always a factor, but i use much less then nachooo, 8w, 3h, "just" UVA, should be on the safe side.
toke allready said some phenos are light green, dinafem wirte also, light green.
but can imagine you saw more criticals then me.

660nm, that could really be that it bleaches more, i cant tell you, its efficient taken as we all know.
the spectrum have a 660nm peak, but all in all its just 20w, wall, on 9 sqare feet and included in the 200w total.

without knowing it really,i say, yes, they simply have enough photons for what they can manage in this enviroment.

114/93 incredible high mg.

He gives em a lotta light and Co2...and i think thats why his numbers are high, well compared to mine anyways.

GreenGenes has also compiled a list of ratios of big brands...i cant remember where it is...but its great...i'll look for that too.

Day 17 flower.

the plant got burned in the past and is riding the edge to take all the light avaiable.

looks like theyre not stretching that much anymore and will stay pretty small.

beside the bleaching, the buds develop quite well.


bleaching is mostly on older growth.
it looks and behave pretty much like describd here.

flower day 24.

well ,leaves arent that nice, but but, the buds, pretty ok, at least there are lots of them.

still giving just about 200w wall watts to the 3x3 area with the mainlight and have no problem having my 900+ at the tops, even in the edges.
still some hours uva and far red, 8 and 6W each.

i try to stay below 1000ppfd, i burned too much allready.

could be nutirents werent on point either, had to flush a small salt buildup, while seems to be ok now.
runoff is atm lower then in, 1.7 in 1-6 out.

otherise its hard to diagnose for me whats wrong if any is wrong other then too much photons and/or not the right enviroment for it.

D24




no algae in the missused clear airtubes so far, will change them when it shows up, have some black at hand now.

Don't wait til algae shows up. Just swap for black before its a problem, buddy.

@cobshopgrow these 56 gen3 EB 2' strips are they 12V? Closer to 10.8 at such low current of 525?

 

[Airwalker16]

Never.and I see now these are 10.9V strips and are 390mm. Very cool. Super price drop at 100.
Can't believe they can Max at 1,700ma. Probably almost 2A if you had it on a beefy heatsinkusa extrusion.

 

[cobshopgrow]

thanks,i will probalby change the tubing soon, just busy with setting up another light.

looks like youve found the datasheet allready, there is nice curve which can be really worked with.

havent tested really high mA so far, my guess is/was 700mA are fine without any cooling.
i dont even use the 525mA, shouldnt be more then 300mA in real i am using.

 

[Airwalker16]

How come we never see bridgeluxs big dawg chip making its way onto anything but these Vesta and EB Strips?

 

[cobshopgrow]

i can not tell, i dont even know which diode they use.
would think if someone want to buy them from bridgelux, they would sell it.

Saying that, on paper the lm301b/h looks better,you would need to use quite some of the bridgelux to get in the ballpark of the lm301b.
while you would also need quite some lm301b to make it comparable to the bridgelux, a few hundred shouldnt be enough.

well, am sure you know the numbers.

below 500mA there isnt much efficiency gain with these eb3 leds, if the datasheet is right (they may didnt evalauted this region well, idk).

 

[cobshopgrow]

some more special strips for a new build.
650-670nm 96pcs 3w led on a HLG 60w (dont plan to use more then 30w tbh)
730nm 12pcs 3w led on a 8w driver (should draw 6w)
360-370nm 12pcs and 390-400nm 12pcs combined on a XLG 25

so far the plan.

I think the efficiency gain on low current is tied to the lower voltage which might not be reflected on the datasheet graph.

Very nice! Are those from cutter?

 

[cobshopgrow]

theyre homebrew
wanted to have some in the same form factor as the eb3 slim to make it a bit easier.

i think cutter have some similar sized ones and a nice colletion of leds beside of it, but i think theres dont have the halfholes i wanted.

 

[cobshopgrow]

@Rocket Soul
true, there could be some gain hidden.
well, cant change it anyway.
the bridgelux chips perform nicely if you take a lot, no question there

some progress

Thats a beautiful build. I especially like how you could easily make it cover more, separating the two halves a bit, with a few perpendicular strips in between. Maybe it would give more even cover as you would have a hole in the middle sorta. Maybe i did the wrong thing ordering the 2 footers.

So those xlg-25-a drivers are to run what? They're only 0.7a. I'm assuming the red 3 diode boards?

 

[Airwalker16]

I'm a total noob to t slot. What's the screws being threaded into? Is there a rail you inserted that runs the whole length with even spaced holes threaded for the holding screws?

thanks
ah, you did well for sure ordering the 2 footers.
you probably bought max diodes for least money for your config.
the 340mm ones fited my plans quite ok for the given options.
combined with the 100 pricebreak, decission made.

i made the gap in the middle a little wider this time as the tent will be slightly bigger.
the middle is a bit hotspotty anyway.

..ill may finally do a par map in the 1mx1m, just dont want to spend a whole weekend on it, may 16 measuremt point max 2 heights, no nice presentation of the data.
would be interested in that too.

.

the XLG25 will drive the UVA section, but youre right it could be used for the 730nm too (while i would use more 730nm diodes then).

4 strips @ 3 leds in series, and same in parallel, so 8 strips in total.
you can push the xlg by the screw to 1.05A, but i dont plan that.
i am more looking for 500mA or less, that gives 250mA (combined series parallel) on the UVA leds (absolute max i am looking for).
