we shall see if these are just good for side lighting,im betting they are better than that.oh and mix it up is my middle name lol
sneak peek,4 x qb and 5 x cree cxb3590,should be around 770w when im done or if i ever find time to fuck with this :eyesmoke:
On paper it should be better than a gavita :hump:

FYI if you are using sheet or plate aluminum, you might be saving yourself some money on those bulky heatsinks by just mounting your LEDs (coBs, strips, whatever) to the aluminum. If the aluminum isn't enough, you can easily bolt on additional cheap heatsinks or fans to increase dissipation. What I have found best for my requirements is that the heatsink temps stay within 2-3c of ambient temps.

Saves on weight and complexity as well. Aluminum plate isn't all that expensive either, I think I paid $14 for a 12x12 1/8th" thick at a local metal supplier. And they will cut as required so you can get all fancy if you want.

CPU heatsinks are designed to absorb quick spikes in temperature which while they work for CoBs, are pretty much overkill unless you drive them hard. Good area to save money on if you need to.

ya thats only $448.00 per sheet haha.i paid a lil less than that @robincnn @Stephenj37826 or anyone else have a link to a quality dimmer pot in the 50k or 33k ? im thinking of tieing all 3 drivers to one pot,will this be ok if 2 of them are 240-1050ma and 1 is a 240-1400ma or 320-1750ma ? all 3 will be meanwells,or should they all be the same if they are on the same dimmer?

That's canuck cash, so like 43 cents yankee doodle.

For your panel, try mounting a couple LEDs just to see how it handles them. It might surprise you.

Digikey and few other distributors have PDB181 and PDB 241 BOURNS Pro Audio Potentiometer.
Parts numbers a little complicated. Let me know if u need want me to look for a part number.
They have 20K ohm and then straight 50K ohm
Coolest thing is that they have detent option available. So far I have found only center detent once. Center detent gives a click at center position.
They also have a 10 detent model but not a stock part.
Rated 15000 cycles

detent would be cool.do i need a 33k for 3 drivers though? and what are your thoughts on running 3 drivers off the same potentiometer if 2 are 1050ma and 1 is 1750ma ? or do they all need to be the same amps output ?

Drivers don't have to be same current. You can even dim hlg240 and HLG 120 together
Potentiometer value = 100K ohm / number of meanwell drivers.

You may be able to find a 30K ohm on the link dawg shared. With BOURNS you will need to use 20K ohm and add a 18.7k ohm or something to total 33+
I will share part number in an hour

Yes 4 boards will cover a 5X5. If you get type A HLG 240 and the slate 2 heatsinks you can crank them up to 300 watts each driver. 2 HLG 240 will and 4 boards will do the job in this way.

  • HLG-240H-C2100 with 2 or 3 or 4 boards for 250 Watts
Would running more boards be more beneficial? Say 3 boards on a 240H-C2100A each?

If I am able to push the drivers to roughly 300 watts, is it around 100 watts per board if I run 3 on each driver vs 150 watts on 2 boards per driver? With the 3 board per driver, I would get more light and better spread, would there be other benefits like better efficiency?



Thank you again, I am still trying to grasp everything :)

Day 31 ( blue dream ) - Single QB panel grow.

Looks like she is starting to get bulky like oprah in a jersey.
Sugar buildup is definitely noticeable. I still cant wrap my head around that i am running a simple 50 Watts and getting around 184 Lm/w with plants looking this good. I planned to add a Deep Red G8 for bloom but it doesn't need it .....

So my initial " TRIAL RUN " with this tech is a eye opening win. My original test was to see how well my plants would do with this panel. All plants grew large and i had to pull the Bubble Bomb out because it was getting too big for space and is now in another room under a separate Fluro light.

The GG #4 next to this plant just preflowered and will stay in here so i can see how this panel works for her.

Note : As far as using this spectrum ( 3000k/3500k) for vegging it has proven to grow new seedlings and young plants just fine. So i will not jump on the 5000k panels soon to be available ....... just yet.
