Heaven Bright Led

I saw a case of parallel failure on RIU too but if I recall correctly, not every light/led being used was of the same make. In other words, it was either various mono led stars, red blue green etc, or various cobs, like a cree and bridgelux mix up. Anyways, don't worry, as I've built many fixtures, most of them being ran in parallel and have yet to have any cobs fail while in parallel. Also, Mean Well approves, the company that makes LED drivers for cobs.

@Federson

When it's your business's namesake and basically your life being put into question, you sort of get angry when individuals try to take cheap shots at ya, especially when it's the same folk

I'd bet that most cob configurations for commercial cob units could handle a fan going out without any adverse affects, like a cob melting down, as they're built pretty tough, especially the Vero but you lose efficiency when Tc goes up.

case I saw was diy cobs all the same cobs, nothing wrong with the basic setup, there was an unfortunate failure of the first cob. forgot why it failed, but not expected.

You should pull it up and show us, maybe I'll reconsider my stance on properly running in parallel, which Mean Well approves of by the way.

Guess what, despite you and your cronies efforts, I'm still gonna be here in the end, and I'm still gonna sell lights and one day I'm going to be at the top of this game laughing at you and the others for all the shit you've tried putting me through.

This sounds a bit paranoid,do you think there are secret weekly meetings where we discuss how to torment you. I have better things to do with my time and I'm sure anyone else on your list of tormentors has better things to do with theirs. We haven't "put you through" anything and any animosity towards you was brought on by your own actions and words.

A lot more to know about cobs than im familiar with. This is the reason I'd rather purchase a light than build one. If I attempted to build a light with minimal knowledge how can I expect success when many bash and criticize lights made by professionals. For now I'll just stick to buying a light rather than building one. Still unsure of when and which I'll choose.

@captainmorgan

What did I ever do to you or whoever else that already didn't deserve it? Can you find another RIU native who went commercial who catches as much flak as me? Can you confirm that my actions and words were what brought on this 'bad blood'? Is this going to be a continual thing or when is enough enough?

Don't let the bickering put you off,this is not the norm around here all tho sometimes it seems that way.

One thing you are ignoring is who cares if Mean Well approves. So the driver suffers no damage and is fine.
What PurpleBuz is saying is one component failing just cost you a whole lot of $ replacing the rest of the cobs that turned into scrambled eggs

Yeah if you don't follow or support, or disrespect the clan, @hotshotisdashit, then they mark you for life. Take me as an example.

@OneHitDone

MeanWell specifically reassured me that the cobs would be fine and that they wouldn't 'turn into scrambled eggs' if ran in parallel and were of the same series. So far all of my experience and building confirms their judgement.

Do you really think I want to upset customers calling me, yelling at me for why their light units unexpectedly died? Come on, dude, I won't make it to the top if that were the case.

lol you forgot something .... meanwell warranties drivers, NOT heatsinks, NOT FANs and absolutely NOT cobs.

@Captain... Yea I know. Lol. Ive been around here for a few years but the led section is brutal compared to other sections. But I do understand that people are serious about their work and beliefs.

I can't speak for others and like I said there are no meetings discussing you. If so many people feel this way towards you,my guess is "your the problem" and not everyone else. I try to live by the old adage that goes something like this "treat people in the same way you would like to be treated". That being said,I also don't believe in always turning the other cheek,what goes around comes around. I don't look to engage in pissing matches with you but I also won't bite my tongue and just ignore things I read here.

@PurpleBuz

Come on guys, just admit that you'd rather go out of your way to tarnish, to belittle my character here, as well as my company, rather than allow me to gain a foothold in this lighting game because you can't stand me due to our differences and past disputes. It has nothing to do with ethics, facts, or none of that, it's that you simply don't like me. Can either one of you go back in the forum postings and pull out one nice or positive comment that you, yourselves, directed at me? Can you? My point exactly.

@PurpleBuz

You really think MeanWell is going to put it's reputation on the line when it's something they specialize in? I'm still waiting on the link to the thread you mentioned or is that just poppycock on your part?

did you ask them what happens if one of the cobs unexpectedly fails?

@AquariusPanta
I don't go out of my way to do anything to you,I read a lot of the threads that are posted and don't respond to most. What you don't seem to understand is,in my opinion all this is self inflicted by you and playing the victim doesn't make you look any better. I'm not attacking your company or products,I even mentioned you might have a good product. I don't know,don't care and won't waste my time to study what you make.

@captainmorgan
@AquariusPanta

But "If so many people feel this way towards you,my guess is "your the problem"....I dont buy that. The tone in LED DIY is very often less than collegial. (im guilty) and there is the nerd bro's, frat boy exclusivity to work around.

There's is plenty of holier than thou, engineering nerd, anal retentive, compulsive momma's boy in the diy. Still I'm very grateful for what i learned.

"I don't know,don't care and won't waste my time to study what you make." see what i mean. That sounds like unnecessarily rude bull shit.

I guess I am the only one that called Bridgelux's tech to question them about the safety of running in parallel? They don't recommend it due to the slight variation in lumen output between COBs. Very few of us run there COBs where if one failed the other would be over powered, at least before the HLG240 and HLG320 started to get used. If you have a 2 COB safety factor, the only COBs that will fail are from you not mounting them right. Every light I have got from China is wired in parallel, not saying they are right, but no fails here.

I can honestly say I fear what product you put on the market because of your lack of critical thinking skills, poor craftsmanship and your lack of respect for the safety of the customer.

Nonetheless I held my tongue on your new mini and mighty mo line until I got a glimpse inside the case. customers deserve the facts and that's what I posted here.

Blah blah blah blah, are you about ready to step off your soap box, darling?

@nevergoodenuf

I'm quite surprised you had any luck getting through to their customer/sales team, as they mostly never are around to take incoming calls. I believe it was @mr.flux who played around with parallel wiring and recommended using same series cobs in the scenario of running cobs in parallel. I also believe he went as far as testing each of the cob's forward voltage but I don't think the cobs mind too much, as I haven't had any issues myself while running same series cobs in parallel.

Your not alone,I've had that very same talk with Supra a couple times. Since Veros are not binned like Cree the variation must be wider,there are some safe guards you can put into place to minimize it but it's not 100% to my understanding.
