Would you consider buying a VERO after reading through some of the posts?

They probably would have caught on sooner or later. $400 is a bunch of money for any company (well some).

I don't know how to scan COBs; I'm sure I'll pick up on it sooner than later but please share with what you find out Abiqua.

I had paid cash and if I had never gone back, I would have be fine....... but yes somebody noticed I am sure....and I might have saved a job by bringing it back :)

I thought I had paid for it originally. So I didn't even realize it hadn't been charged, unitl I returned the item.....

I'm curious of what is the best driver for Vero 29's and which Mean Well driver should I use. Preferably multiple per driver and perform with high efficiency

Another thing to think about Real, something that StarDustSailor brought up....these Vero's are different beasts than the 3070's. For one they can handle more current and are usually more efficient than Cree's when ran above 1.4 amps....plus they have a big slug of copper for a base vs the cree ceramics. Not better, but bigger.....so the Vero's can be ran in excess of 2 amps each and I believe max is 4 amps!

With that in mind, the HLG's you are already using, are your best bet for multiple cobs. The Vero's run a volt or two higher than the Cree's at the same current, so that is an easy comparison, for determining how many cob's you need.

There are also the HLP 42's....open version's of the HLG, but rated 42v's @ 1.95 amps, although SDS reports these will go up to 2.2 amps....these would be a nice driver for getting tons of light overhead even though efficiency is decreased....:peace:

Got it loaded and I am also using my webcam [for the 1st time ever]......command prompt shows up and initially it took one still and now I can't get it to take another still and cannot type in the command line either to access Help....still working out the kinks.....:peace:

Salmo......about to try again, using W8, ugg, dug out the command line prompt

[[[ [suspiciously, it "auto-loaded" it on the front end and worked the camera, but wouldn't accept commands or take an actuall still shot, weird????....]]]]],

adjusting my lighting and trying again and going to read those discussions as well, [was poking around earlier in there....hadn't found anything substantiative, so thank you!]

@salmotenin
thanks again for your reply, I edited for this thread....

Zbar has been shit for Windows 8. Finally figured it out, but I will have to go into the forums again, because the camera is not being recognized.
I am having problems all over the place with it...One more try, just unistalled/ reinstalled and then I am restarting comp, after this message and trying it again.
:peace:

One other thing, big THANK YOU to Digikey. They responded promptly and are sending my original 5k Vero's, first thing in the morning.

I now have 2x 2700k Vero 13's to play with, not much but for this microgrower, this is phenomenal....I now have or will be testing all Vero spectrums [although not all CRI's] except for the 4000k's,,,,soon soon

Do I need PWM drivers for an Arduino to shut them off? Not necessarily dim, just turn on/off. Or a PWM relay, if such a thing even exists?

Want to pick up an Ard UNO this week..:) and start pushing buttons! bongsmilie

I can send you some code for controlling them from an arduino. You'll have to do a little extra as they use 0-10 for pwm and the arduino only does 0-5.

I'm trying to cool 4 vero29s with the alpine 11 plus cpu coolers. i have no idea what kind of driver i need to power 4 of them at the same time. could anyone point me in the right direction?

Scroll up to the top of the page (21) and check out that link I included, as well as the comments that ensue afterwards.

The HLG series is hard to beat (~90% efficiency and up + PWM control) for multiple COBs in series.

I was told running multiple COBs in series was a bad idea because they have a tendency to draw differing amounts of power and this can lead to thermal run away.

Plus the LPF-90-42 are not to expensive... They were like $42 a piece when I ordered 10, and I can get them for $36 if I order more then 25 of them... 90% efficient, plus if any of them malfunction for any reason you can replace them individually.

You could use an LPV-20-12 to run the fans for the Vero 29, they are $10.

Either you or I are misconstrued with what we heard. Actually, I run my infrared stars in series and they work fine.

I think it's running LEDs/COBs in parallel that is strongly opposed but then again, I see people occasionally doing it. I run my fans in parallel with a single PSU (no issues yet).

We could probably use a new thread that discusses this subject in further depth, although I don't object to someone(s) posting their wisdom on it.

Have you used the LPF-90-42's yet or?

They say not to run them in Parallel they actually recommend Series in the data sheets. Not running LED in series is pretty old info it was useful when production techniques produced led's that had a wide Vf ranges out of the same production batch. It is not really relevant with quality COB LED Arrays these days .
But if i was going to run vero 29's i would go with the LPF-90-42 to run them at test specs 2.1 amps. Bad thing about the hlg series is 1400mA is the highest you can go and you can only power two Vero 29's off one of those.

Damn I have 6 HLG-185H-C700A's so I'll have to get different drivers to run Vero 29's but fuck it.
