Another great video. I would have to say the only real problem I had from the last video was understanding how to calculate heat watts for a specific cob at a specific current. I would say that reading the brake downs on each cob on the rollitup forums took me awhile to fully understand. I am not sure if any one elsa had that problem but it might help to show a brake down and walk them through each column. I just built a 300watt light and it is just amazing and I owe that all to you. Thank you very much for your generosity and expertise. I only found your channel a little over a month ago and I already have a light up and running. It would have taken months more of research to realize this cob light without this channel. Thanks again..

Most DIY basic videos here on youtube always either brush pass the technical understanding aspect (theory) of the subject or they jump straight into their "model" of the project, again, not touching the technical stuff. So, for those people looking for "just show me how to make one by the end" type of video..then this aint for you. But if you trying to understand the basics of the technology from a common man avergage joe point of view. then this is it. Great job bruh!!!!

The most important thing to understand about LEDs is their typical NTC characteristic. The higher the self-heating, the lower the electrical resistance. If the LED were operated at a constant voltage, it would convert an ever-increasing amount of power as it warmed up. This would lead to thermal self-destruction. To prevent this, the current is regulated. The voltage across the LED drops as the temperature rises (see Ohm's law). This stabilizes the system and automatically reduces the output when it gets hot. This could have been emphasized in the video. Otherwise very well explained.

Good video very informative as you were explaining efficiency I realize you were talking about Ohm's law. Basically the higher the voltage you run the amperage will drop down automatically and the watts stay the same. Using higher voltage with anything is more efficient. And since you have to match LED voltage with driver output you're also spreading the load and the heat will be lower due to view material in between the LEDs.

Just out of curiosity...Why does it seem that manufacturers always run numerous LEDs in series rather than parallel? Or, why is it more common to use high voltage and low current, rather than low voltage at high current? I would rather see one LED die and not take out the entire fixture, but for some reason that's just not the way I'm seeing things designed.

Awesome video! I know you needed to keep the explanations simple, but I would explain why current accounts for brightness because we are dealing with setting up our own system after all. In reality, power output in watts determines overall brightness. P=V*I which means that power is dependent on voltage and current (and resistance). We could hold current, at a fixed value and increase the supply voltage and change the resistance to maintain the same power output (or even keep current and voltage fixed and change the resistance etc...). However, in this case we would be talking about a completely different bulb because the filament (resistor) in the bulb is fixed (unless a variable resistor allows for dimming), and at the same time, the wires connecting the bulb and the power supply keep the voltage fixed. So we can vary the draw of current and therefore change the power output (brightness) of the bulb through current. (*Note I'm no electrician, but simply needed clarification after you mentioned current was everything. Please correct me If I'm completely wrong. Been I while since I "physics'd")

Dude, you have professor level teaching skills; articulate, clear and to the point. This however, almost seems to be backwards (for lack of better explanation due to my ignorance) compared to how I've understood electronics for computers, household and automotive, where the voltage output on the power supply, amplifier, breaker panel, etc, will remain stagnant with only very slight fluctuations, depending on stress or load and of course operating temperatures, but the amperage or current draw increases with load or more devices added. I'm assuming this is because the COBs are running in _Series_ ? With car speakers we typically run in _Parallel_ to drop the Ohms, thereby reducing resistance and increasing current flow or draw for more power output and I know if you run it in Series it would have the opposite effect of raising the impedance or Ohms, increasing electrical resistance, thus decreasing power output

Thanks a lot! Your videos actually made me decide to build my own LED instead of buying a premade one. One thing I´m just pretty confused about is the Output V of the driver. The driver you showed in the video says 286V, yet if you look at the PDF from Mean Well it says " 143V ~ 286V ". I´m not sure if I would be able to use 4x COBs with 36V each now on that driver - since that that would be 144V together, but since It´s 700a it would probably be around 142-143V. My question is basicly if it says 143V ~ 286V on a driver if 143V is the minimum V I can run on it.
