On board sure.
We will. Issue is we go on show and run out of boards...... We will have even more haters . Lol

Thanks @Growmau5
Let me find all my cool heatsinks and projects. @Stephenj37826 and I will reachout to plan something.

make sure if and when you guys do this we all have notice.saturdays are good for me lol,i have a hell of a time trying to watch the roundtable on friday because im always out slingin nugz to my patients.hey bro,running out of shit is a good problem,beats sitting on inventory that is outdated right ? :bigjoint:

Just a question, but what is the predicted failure pattern of the individual LED's expected to be. Will it be a single dead LED and the remaining stay lit, or will a string of them go out (and how many to a string)?

So far hard to comment on failure rate and none of failed during use. Few failed as my driver cable touched wrong spot on board.
You lose 1 row if u lose a diode.
1 row is 38 diodes.
There are 8 rows so 38x8 = 304 diodes

Its on!!!! Ill take 100 of each :hump:












Kidding, need to give all the newer members a shot at these.robin,hit me up when the dust settles in a few days and if theres still stock left on qb and slate 1 we will figure it out.or i will wait till next order if needed as im still building shit here anyhow :)

Hey Guys, i'm completly new here and also relatively new to the whole LED stuff.
I Wanna build a DIY with those sexy Quantum Boards! Currently i'm running with 16 Nichia 108 COBs,
so i know the basics. But what i dont get exactly is this:

chrome_2017-02-02_12-49-05.png

So - for me - it seems like, if you're running those boards in Daisy Chain, they'd all consume 108.3V to 112.5V (depending on the board itself) EACH. But The HLG-240H-C2100 can only provide 59 ~ 119V.

When i build my Nichia108 light, i knew that every COB will consume a certain amount of Valtage, and as long as the driver offers enough Voltage for all COBs, the lights would switch on.

So before i order the whole stuff, i wanna make sure it'll work (I live in germany, so the whole process of ordering will take much longer :)

So my question after all this is :
Why is a HLG-240H-C2100 driver is capable of running 4 Qunatum Boards in series (althought they consume about 440V together)?

I'm thankful for every answer!
Peace

The picture above is parallel wired not series.

When in parallel the voltage doesn't "add up". When in series it does. Parallel the current is divided amongst the boards. I.E. 2100 ma between 4 boards would be 525ma driver current to each board. You can add as many boards as you want in parallel as long as the voltage matches. So you could start at 4 boards and add more later to further underdrive them.

So with 2 boards ordered I am looking at this as the best option for me;

HLG-120H1050B X 2

Reason being is I need to spend 100 to get free shipping. So going this route only cost a few dollars more than one

This way I can run each board independently.

This will allow me to in theory root/clone/Veg in one small area and allow me to manage heat.

If I did my math correctly I will get around 110 watts per board?

Or I save $20 and get the HLG-240H-2100B and get another 30 watts bust would have too dim as a whole.

Im torn between Cost/watt and the ability to run independently.
