Well im on my way doing something similar. Ordered a cob chip and a driver. But a little changes in life did that i can not justify spending more money on some hobby project so iil put it on Ice for a while but i can still think about how to proceed when im able to order more parts and so on.
I have for the moment
Driver: mean well HLG-240H-C1750A
It is rated 250w. It puts out 1.75A constant curent and should be (i do not know this tecnical words in english, im sorry, I dont know how to express myself in a professional way even though im educated in electrics, but that is in swedish), but yeah anyway.
Output load should be 71-143 V.
And i have a vero 29 also. This one i got is the 50.7v version. 3000k 90 cri.
So this is what i got. My initial plan have been to order another chip like this one i got. Then iil get about 100 v load if I put them in serie. That is going to work, if iil run them at full current they would be like 90w each (88.7w)
But i think im going to also buy another vero 29 chip but the 36.6v version, have it eat those 1.75 Amps aswell and then iil be generating about 240 w effect with those chips.
My driver is that one with built in potentiometer so i can go from 50-100%.
So, initial plan. This is what I have been thinking of. But now ive been introduced to those stripes here and yeah, arrays of smaller leds. So dont know what to do. The cooling is a big thing. It would be expensive to order passive cooling but that would be better. But maybe iil go for cheap and go with active.
Dont even know really what to use this light for
I would be glad if you capt. And also you kmb would post a link or something so i can see what heatsink you use. And also pictures of the things u built would be nice!
As soon as i get my hands on something else with a voltage drop over the component so iil end up in this 71-143v range iil start testing this shit out.
Would be fun to se the growroom of yours with the lamp capt.!
