I do not know why it is so lame for you. Maybe since different language. Look in my albums, in my profile.
Be well!!
Would running 8x Vero 29s via 2x HLG 240H @1400mA be too much for 2x4? Looking to replace the 400W HPS I have with COBs to give me super even spread over my area.
I'm trying to find a good compromise between canopy penetration and spread especially since I don't have much height available. My HPS stays 12-14" from canopy with no heat issues but I'm worried COBs can't be that close. Open to suggestions!
I am just an idiot, but 4 of those, run at 90 watts each would be overkill. These new Vero's are state of the art, and best value.
I plan on replacing 2 X 600 HPS for 4' X 8' tent. Will be 8 X 90 watt, which the new Vero's can do. So 4 for your's is overkill, and will need to be dimmed, which is built into most power supplies.
Those kits were 416 US dollars or 600 Australian dollars, and were running at 90 watts each. Is that still a bad deal? Shipping is a bit high. $211 for 4 kits to USA. Thanks for the reply!!
yeah i know, I'm talking australian dollars, so about 30% cheaper as per my suggestion.
Dion thanks for the great thread
I need to add sum prob vero 18's about 4 of em? and dimmable driver prob will be that guy and run em alil hard for awhile and in a month or 2 if possible add sum more cobbs. but could use a hand finding the right cobbs and driver/ drivers. Will be to used for a flower time boost more then likely later again with bigger cobbs
there are decent 25xx chips etc etc but idk one ya get the holders n shit n trying to get mostly at one place to save shipping gets harder etc may consider even a setup of less chips of bigger series ... but this is a lumen hunt at the moment not a efficiency hunt
On another thread, someone said LED's were no good because they lack UVB. How many watts of UVB per square foot, would be needed to supplement an LED light????
What a great thread. Made for very interesting reading. Really making the decision between the 315 cmh and a cob array very difficult. I've been very impressed with how far LED's have come in the last few years.

yes thats exactly why you should run them in parallel.
I usually have about 5 convos going here, in other forums and via inbox so pls forgive me i have no idea what size ur garden is.
last time i looked at the data sheet for the vero 18 gen 7 i was not very impressed....cant remember exactly, i think that they just were not too efficient and by the time i added the price of the extras(TIM, holders, reflectors ect) it didn't make financial sense to use them
for the lumen hunt the vero29 is what you want... absolute cheap cheap way use the 'A' version of any HLG 36volt driver. The A version means no external dimming, but it also gives u extra volts to play with which will cover the 37-39v that the vero 29 need.
so you rig em up in parallel and the current of the driver is divided by the number of chips, more chips you use less current to each one, becomes more and more efficient as you add cobs onto the driver.
you could even start running them at 100w each and put a pc fan on the heatsink, then add a few more until you get to around 80w each, and in this case dont need the fan.
at this point im just looking to get a few small cobs for sum extra supplemental lighting. I do plan on cooling em have a buncha fans and coolers already pretty much everything other than cobs, drivers or much to spend. Reason i was looking at veros more over like a 25xx is so i didn't need to get holders and wasnt to worried about reflectors either, but the wire connectors looks like a nice option. I havea 40"x40" and a plant next to it each could use alil more light another reason im looking at more 10$ cobs v a couple 20$ cobs with the very limited budget at the moment for this supplemental lighy build.
by spring i prob will be reorganizing, splitting things up and adding a nice size cobb sys.
trying to explain best I can, I often have a hard time getting my thoughts out thru these head injuries and constant migraines. I'm Trying to get the most out of these ladys as they help more then anything else! last round has been gone this time there way larger which is good but the lights just arent enough nor getting the penetration good ladys need
