DIY with Quantum Boards

If my quantum board is flashing, is it most likely a driver problem? If so, meanwell is weak crap.

It is mass manufactured by the thousands like everything else, there will always be failures every so often. Retooling to make those things bombproof would significantly impact the price.

PS Stephen please ignore the minty guy... the rest of us all do

No problem guys, it's a QB96 board with a GSC40E-1400 driver, the driver is recommended on HLG's website. I bought the driver and board separately so HLG is in no way responsible. I also had to chop off the tip of the driver's cable and soldered the cable to the board, so there goes the driver's warranty. I have 8 of the boards and drivers that have been in use for almost 2 months, one of them started flashing today. They aren't in a sealed place, but the ambient temperature in the room is about 34 celsius.

I'll remove the cable tommorow at work and test the board with another PSU. If it's a problem with the board I'll let you know.

The driver is still covered... They will replace it.

Actually one of my Delta drivers is also flickering slightly... been working OK for months in the veg room now, so I'll just let it do its flicker thing.

Ok, does sound like a driver. stuff happens. And I believe your DC plug will work with this female adapter, save you from cutting up your PS.

Shoot us an email.... Whatever the problem rest assured we will take care of you.

Any thoughts on QB 120's or 132 with LM301 diodes ?

The future looks good...

Hey tty! How you doing? You growing again yet? I miss your thread, it was stellar!

Hey buddy!

Still fighting the fight.

Thanks for the kind words, brother!

PM me sometime.

HLG got some pre prod samples of Samsung new LH351B Red

Put them in an oven to make a 11 LED strip for testing. Test Report

Osram SSL, SSL Square and LH351B Red

Want to send any testers out

Is 1/16 inch thick angled aluminum strong enough for qb120/132s? Or is it necessary to get 1/8 in thick sections?

It depends on what all you're trying to put together, the longer you make it the more it will flex and the more hangers youll need on it.
What size are you looking to make your frames?
I used 1/4x1/4x1/8 for mine and wish I would have used much larger stuff.

I wonder if our armchair engineer tested his Chinese boards this way.........

Can't wait for these! Hey stephen, I haven't hear much about the QB324. Can you clue me in one how these differ from your other boards and how they may be better or worse or how they can be taken advantage of?

QB 288 V2 is the most efficient board as it Level 2 by Samsung and gets the best Voltage and flux bins of 301B

QB324 is Less efficient, much lower cost, can be run 2ce as hard, optics compatible for better light control, 80CRI 2700K + 90 CRI 3000K for more deep red in spectrum

https://en.wikipedia.org/wiki/AC_power
Types of Power consumption of a lamp. They all seem complex but it is not too bad
Active/Real power, P
Reactive power, Q
Complex power, S
Apparent power, |S|

HLG 550 V2 test report
https://cdn.shopify.com/s/files/1/1538/8585/files/L051802301.pdf?13084313055403839388
Voltage 220.00VAC
Current 2.19A
Power you calculated =220x2.19= 481.8watts
If you 1178.05 PPF/ 481.8= 2.445 PPF/W, but this not correct
This is because the power you calculated is Apparent power. Apparent means Apparent

But report shows 472.90 watts
That is because driver is not purely resistor. I think it is inductive
Active or Real power= Voltage x current x power factor
=220x2.19 x0.98= 472.164 watts

power factor= the ratio of the actual electrical power dissipated by an AC circuit to the product of the r.m.s. values of current and voltage.

So if you see a company claim 2A at 240V. don't divide PPF/2x240 to get PPF/W as it is not accurate.
Look for Actual power consumption as it is mostly likely less than Voltage x Current

I’ll have to look into this! Thanks for sharing. You guys having a booth setup or what?

Was going to make a 42 inch x 12 inch frame essentially with 1 inch angled aluminum 1/16 or 1/8 thick. Running 4 qb 132 on a hlg240h-c1750. Driver also will be on the frame.
