Why would I do that? IT WAS A TEST! No, I was not concerned with the current level, IT WAS A TEST!
Just curious as to which driver you used?
All I knew about the CoB is it was a Citi 1212. But that did not matter, I presumed that the proper diver was chosen for which ever 1212 Vf. I did not realize that you guys did not know how to choose the proper driver.
The reason I had even mentioned the 1800ma was just hypothetical because someone a few pages back was insinuation that a CC driver can not over power a led. And when I say "power" I am referencing watts. I thought CC drivers could overpower leds hence the whole reason most people advise against parallel wiring because if something happens to one COB or led than the others will have to share the additional load.
Absolutely nothing wrong with using the HLG-600H-36B to drive a bunch of citizen 1212s in parallel. The driver will limit the voltage to around 36 - 38 volts and the cobs will run just fine without risk of runaway. The current will be around 1800 to 2000 ma.
Good spin, spoken like a true politician.
I didn't say I use a 36v HLG. While a 36v driver will not push a 1212 gen5 to it's absolute maximum current, most run them close to nominal current.
With no doubt the 42v. Just by looking at the graph in my previous post it is obvious the 36v is inadequate to operate the CoB over its full range.
How was I to know the wrong driver was being used? I did not have the CoB part number. "Citi 1212" has 4 different Vfs.
Seems so. Not necessarily true. Certainly can be. Often misunderstood.
A driver should be able to operate over the full operating characteristics of the CoB. This usually means the driver can over power and burn the CoB. The datasheets are only typical values. Getting the values for yuor specific application is not a trivial task. You must consider how the current and temperature affect the forward voltage.
See, now I don't even know!
Little late to the party. That was never a secret. But guess what? I still have no fucks to give. Some how I always thought you were old enough to understand me. But no, you don't get it. You seem too grouchy. Still I like how you do things here. You know what you are doing. Many others here do not. I especially liked your experiments with the Décor 1750K.
I started with "likely" it would burn.
good god dude you just can't admit that you are wrongI started with "likely" it would burn.
Carefully chosen because I did not have all the necessary information. Now it's should have burned. It would if the proper driver was chosen. You can use whatever driver you want. I do not care. I'm only saying the 42v is the far superior choice to the 36v. Take it for what YOU think it is worth. I do not care. I'm just the messenger.
bullshit
The min to max Vf of this CoB fits much better in the 42v HLG. the 36v is not the correct selection for this CoB.
Do as you please. Just letting you know the 42v is a much better choice. Do with that tidbit as you please.
Absolutely nothing is taking it a bit too far. The 36v does not operate within the full capabilities of the CoB. The 42v does. If you'd rather be a cripple, be a cripple.
Yes I can. But only when I am. Is the 42v a better choice? Or is the 36v a better choice? Answer 42v. Facts are facts. Are you too blind to see or are you just brushing up on your ignorance?
