Same here man. 12 years old and I'll drive it till the wheels fall off.

I love seeing that damn Dodge Fanlaef! MOPAR bithces!!!
 
Sorry all I get a lil excited about engines and car talk! Lol
Haha I have a 15 year old truck that I'll also drive the wheels off. Or put her in a wall and not be able to fix her! :(
But I have built and rebuilt this girl over and over. Every time she gets just a lil bit faster! And more expensive lol.
I probably could damn near built me a house for what I've dumped into my baby lol.

I hear that. Rebuilt a jag as my summer car. Pulled the motor, paint, new tranny. Replaced entire suspension.
If I couldn't have done it myself I never would have bought it. It was pristine but neglected in the parts area. 25 years old.
Mostly original parts when I got it.
 
I switched out the 100k pots with 86k and 88k per recommendation. After running then full blast for about 15 minutes this is where I stabilized. Vero 29 SE with 4 per driver. It was said to top out around 218 so I am curious as to wtf is happening lol.

Edit - also wired up the chips with 18 awg 600v wire. Bit the bullet and bought a 500' spool for this project.

Is number 3 turned up all the way?
I ve returned 2 drivers so far because they didn't put out the rated current/watts.

Yup. Just swapped out drivers and it is at 165 watts. Number 4 keeping climbing and hit 188.

Turn the chips all the way down and inspect the COBs for defective diodes. Use your camera or sunglasses to see them clearly. Sometimes screwing them down too hard breaks them.
Other option could be a Bad meter (swap driver to other meter to test). Really bad pot. (Desolder and test with open circuit pwm. )
I've got a 1750 cooking in my tent. Pulls 218 at max. I run it at 178w max. I won't crank it up until the last two weeks of flower when I drop the tent temp to 2-5C for a cold finish.

You are sucking your driver dry arent you? What does that chips voltage run at 1750mA? And why on earth go to an 80k something pot?

There's about 10% dead travel on the 1750 with the SE chips. Reducing the pots ohms gets rid of it.
There's a point where the SE doesn't get any brighter on the 1750. Just hotter.

The very simple answer is that this is absolutely the WRONG driver. This driver runs out of voltage at 143 volts. Vero 29SE at 1750mA HAS TO HAVE roughly 38 volts in order to run at 1750mA. 38V times 4= 152 volts. You simply have the wrong driver my friend.

That driver will only provide 143 divided by 4 =35.75 volts per chip. At 35.73V they run at roughly 1050mA. This proves my point because your voltage available from the driver is 35.75 X your 1050mA= 37.53 Watts per chip! 37.53 X 4 chips= 155W........Your sucking your driver dry bro. Wrong one.

That's because at that point on the dial the driver is out of peak voltage and cannot go higher if it wanted to. That driver will NOT power 4 29SE chips to 1750mA but closer to only 1100mA which is exactly what he is seeing.

It keeps climbing because the driver is trying to catch up but cant. Sorry brotha but bad driver selection.

Well I'm driving the exact setup and I get 1.4a at start up and much higher after the system is hot. 1.67 I think....don't quote me) I'll show you later, day 2 of 12-12 and I don't wanna light them up when they're sleeping.

He's getting 1.55 A on the driver right beside it. I'm assuming it's the same driver and chip setup.

If you want to run 4 chips per driver you need either of these options.

1. HLG-240H-C1400B. This will allow you to run them at roughly 50.6 Watts per chip. 201W @1400mA
2. HLG-320H-C1750B. This will run 4 chips at 1750Ma. This will run at 65 watts per chip. 260 Watts!
3. HLG-320H-C1400B. With this driver you run 6 chips not 4. 50.7 watts per chip X 6 chips = 305 watts

Yes but if you suck one driver dry and another one is being sucked dry right beside it don't mean you get the same result. They are guaranteed to do 143V @ 1750mA. Once you go past those specs (like he is) they will never be the same. At that point they just put out everything they can. 1 driver will be different from another when you operate them out of their advertised specs.

And the fact that he's only getting 1.55 amps on a 1.75 amp driver tells you they are out of voltage. A 1.7 amp driver will always do 1.7 amps when the right chips are hooked to it not requiring more voltage.

If he hooked up 3 chips to that driver he would see it can suddenly drive to 1.7 amps and out of just 3 chips he would get 200watts out of just 3 chips.
 
I'm running 4 29's on a hlg240c1400b. I'm getting max 218 to 220 watts at wall. Haven't tried to calculate anything but figured driver is putting around 200 watts to chips and rest is to operate driver. All my drivers are pulling pretty much same at wall. I have some D.C. Meters I'm going to try to swap out the ac meters. Then use an AC meter in each branch circuit (I have 2 20a breakers feeding drivers), and a third 20a circuit feeding my accessories.
