About a single 1,32 Watt fan per driver ...Oh that is sick, could run the fans on that 12V! Not sure how many you could power with only 110mA though.
Fine for most 140 mm fans ..

The helvar looks a lot like the meanwell lcm.....lots of crossover parts it seems. Meanwell a reseller? I thought they were designing these drivers themselves until I saw the lsdpower resemblance.More fine ,high -quality driver options at 1.4 A .

Build a light that is superior to HPS to be able to get your return on that investment. So Vero 29. I use 3500k.@stardustsailor @Positivity @SupraSPL @churchhaze i sourced an inventronics quad-channel 160w 1.05a driver. I want to do 4 cobs on a 24" x 4.75" heatsink with 2 120mm fans. Having a hard time deciding between vero 18 and 29. Was thinking of doing 3500k or 4000k. What would you guys do?
These are Supra's numbers, for the V1.2 though: https://www.rollitup.org/attachments/vero-18-29-final-efficiency-png.3296413/At 1.05a i'm thinking the lumen output would be similar between v18 and v29, that's kind of what has me stumped. Not sure if the cost difference would be worth it.
Edit: U-ti-liz-ied.
Just gotta think about how those lights will be spread. V18/V13's really spread the light (and heat) nicely over the canopy, with V29's you may notice a difference in the buds directly under each light, and the heat can be intense directly under them.At 1.05a i'm thinking the lumen output would be similar between v18 and v29, that's kind of what has me stumped.

@Don Petro
The cost for the Vero 18 is lower, maybe averaging as much $.50 per PAR W less than a V29...but at a lower efficiency averaging around 4% difference...
Myself I am always drawn to efficiency due to my circumstances, but it would be tough to argue that amount of savings, for not much of a penalty in efficiency
Go for the V18's unless you want to run 3amps in the future ala the V29.....
Thanks guys! I was thinking that the 18's would be more forgiveable when it comes to canopy distance and spread. I really liked the 4000k on the last 4 panels but i'm thinking 3500k for this one. Plus it seems 4000k is tough to be had these days looking at stock numbers on digikey.Just gotta think about how those lights will be spread.

I have some Vero13 2.0's driven at 350mA and my strawberries don't seem to mind being a few inches away.
Good luck panta..when do we get to see the light?
Thank you and perhaps soonerGood luck panta..when do we get to see the light?
Nevermind...found it on the site. Second week of june..
Yeah I think I'm going to copy that setup. I was looking at Cree's CXB3070 but the price difference for the vero's and that driver is super tempting at 1/4 priceThanks guys!

If your going to build a Vero, mine as well Use a Vero, everyone likes Cree because we have more. Grows using them and that is all how this obsession started (thx supra) but from every page I read and specs, the Vero cobs are better at running high w(75), so it's more up to how many watts you want to run.Yeah I think I'm going to copy that setup.

I can always use the vero bar for a veg. light later and build a cree one.
I'm so pissed! LOL jkSuper cool Panta... ROFLd at the song choice/title.
I just built a bar of 4x v2 Vero18s dimmable from 1050mA down to 525mA.
I made sure to get 90CRI versions (3000k,4000k) just to piss those select few people off~ Need my connectors so I can fire it up already...
All leftover aluminum/fans from other various projects... Frankenlight~~
I think a lot of it has to do with efficiency also. 3590 gets up to 50% efficiency when run soft, which blows HPS/MH out of the water, which is what a lot of people are trying to achieve. So if you are aiming for the highest efficiency possible a Cree chip driven soft is the way to go.If your going to build a Vero, mine as well Use a Vero, everyone likes Cree because we have more.
