Best driver (current) for 3 Vero 29???

Wondering if hlg185-20 will run 3 Vero 29, or do I need a 240???

right, so is this a series or parallel connection you want?

20? 2100mA

Do you know how to calculate your Voltage Forward @2100 mA? If in series just add your voltage for each cob...if it is less than what the Meanwell 185 puts outs in voltage, it will work.

Although this chart seems to be wrong. The HLG-120H-C1400 will not fit 3 Vero 29's since at 1400ma the Vero is using about 37v per cob or 111V total, over the maximum of 108 the driver gives you.

Series, but I've looked at the data sheets. For a Vero 29 and for a hlg 185, where does it say how many volts does a Vero 29 but out. I find vf of a Vero29@ different currents. But how does one find out how many vf a certain hlg 185 has at different currents? That file isn't working. Thanks.

Ok f-in awesome!

You can find the individual spec's for each cob HERE

But watts do come into play?

Driver info is available HERE

Look in the 'Description' column and you'll see the drivers state (as an example) HLG-120H-C700B and under the description column it says 107-215V. So 215V is the maximum for that driver. The Vero 29 running at 700ma uses 35.6V so if you added 6 Vero 29's to that driver you'd be at 213.6V or under it's maximum.

Watts = volts x milliamps/1000
for example 36vdc (cree3590) at 1400mA = 50.4 watts at the LED.

Drivers??
for example Pick the hg-185-c1400 is rated at being able to give LEDs up to 200 watts total. From chart above Max voltage = 143 volt. How many 36 Vf LED can this drive? Same chart says 4.1 cxb3590 cob COBS.

The hlg-185-c1400 will output 200 watts at 1400ma to 4 cxb3590.... 150 watts to 3 cxb3590,....100 watts to 2 cxb3590...see the pattern?

Thank you unfortunately I have to buy veros. $$$. But I you have been very helpful. That chart seems a little dated though. Any idea where I can find a newer one. To me it seems like Vero lend themselves to a higher drive current.

It seems like running 3 Vero 29 on hlg 240-2100 is about the best way to go. Any idea how many vf a 320 holds.

I use 3 vero 29 3000k on a hlg 185h c1400b running at 51w per cob. There is some spare voltage but oh well

Are you running the HLG 185h at full current. Ie. potentiometer turned up full?

Look at my post in February. That's Gen 6. Now use HLG 240h-c1750 with GEN 7. 2 50V (4000k) on outside, with 1 37v (3000k) in middle.

Just put one up today in my facility, can't believe I don't have pic. How about 2 Vero 68v @1400 ma.

Same driver more effective. That's open to much debate.
HLG185H-C1400B

Fuck, I change my mind. 50V's & 1 37v.

I'm using 3 BXRC-40E10K0-L-73 36.8V 2.1A chips on 140mm fin pin heatsinks. I bought them in June, they became obsolete in September. Lol. I'm running the HLG-240H-C2100.
2.1A chip-2.1A Driver. Costs a little more but worth it I think. I figure I can always buy the Gen7 D-73 for $30 each or what ever comes out next when I blow these chips from overdriving them for 6 weeks in bud. Lol.

I'm with your thinking. GEN 7 can be done @ 1750 and probably 2100 on the 4.6. I'm working on a 75in bar with with 2 HLG 320-1400 on it. 6 4000k 69v.
No pic with drivers

Often I find myself chasing my tail with some of the advice I get here.
No fan of pinned as well. Plus this store is down the block
