304 all the way. Eff is what we want.288 or 304 boards?

Diagram would be great.....LOL2 boards in series, and then those 2 "strings" in parallel.
Nope,seeing how people get all hissy about other players posting in there threads look at what ive posted in this thread you will find who it is...So what's the big competition you're talking about? Sun boards?
Thanks for sharing this. I will do a PAR map and get back to you.hey robin have you done any PAR readings with and without the acrylic? it has excellent transmittance on axis but im wondering how it works with such a spread out light source?
looking at the datasheet for lm561:
View attachment 3925393
then the transmittance graph for acrylic:
View attachment 3925395
it looks like about 25% of the light is cast off at above 50 degrees where it would start to reflect off the acrylic. so this would bounce around between the acrylic and the white board
I'd guess the losses might be closer to 10% than the theoretical 8%
4x qb304 with 480h-2100. you have correct wiring in Pic
Is this it?
Dimmer one 100k or 2x50k(one in each leg)?

They even have optics as well.
And they build them in house as well so no out sourcing...
They are a advertiser on here as well..
They are working on proto types now
boards 300x300 first run of 1000 boards cost is tbh.

This is type a. No potentiometer for dimmingHere is my frame. Re purposed an old antennae for some thin wall 1" square tubing, then had to buy 2 sticks 1"x1"x72" aluminum angle.

I was hoping for a way to not have to lower to get to screw.... LOL.This is type a. No potentiometer for dimming
Use scree driver. Details on previous page.
It is a free market for sure. But reputation, reliability and customer support add very real value to a product offering. It’s going to be hard to beat HLG.Nope,seeing how people get all hissy about other players posting in there threads look at what ive posted in this thread you will find who it is...

Yea, I deleted the link. gotta respect the o.g. HLG, I posted it cause recent post were about acrylic and the enclose was just awesome hah. im looking for my QBs to be coming soon too brother!Imitation is the highest form of flattery, I can't fault either HLG or Cutter! They're both great retailers to deal with and I'll happily spend my money with either of them. I bet chilLED is equally as good, as a consumer I want to try products from all of them eventually and competition is ultimately good for the person opening their wallet.
I hope this thread isn't turning into a sledging match, what other companies are doing isn't exactly the same as HLG. Yes they are all using the same samsung diode but that only makes sense seeing as it seems to be the best mid power SMD out at the moment for horticultural applications so that was bound to happen. After all they're all trying to achieve the same thing, delivering photons to plants in the most efficient way possible, there's bound to be plenty of overlap in design and materials used.
It doesn't seem a lot different to every company using the same COB LED's and drivers in light builds. In my eyes what cutter is doing isn't the same scenario as the fellow who got the exact same design out of the same factory HLG is using then posting it here in Robin and Stephen's thread, there was no way that wasn't going to step on toes.
I hope this thread can stay on the topic of Quantum Boards and not be as concerned with what other manufacturers are doing, because when somethings good it's bound to catch on everywhere.
HLG has been fantastic with communicating with me whilst going through the purchasing process and getting them shipped overseas, I very much look forward to using the boards I've purchased!
Lol so reliability,is every time you go to purchase boards they have no stock...It is a free market for sure. But reputation, reliability and customer support add very real value to a product offering. It’s going to be hard to beat HLG.
Gee, would you rather they charged twice as much so they'd always have stock?Lol so reliability,is every time you go to purchase boards they have no stock...
Yer bro,this what got them to where they are now,and trust me its not all the same rules here for everybody...As in advertising.....
Im very for a free market but there are some here that are not....
So you could do better???? Where is everyone elses "stock"? It's an 8-10 week lead time on the LEDs. Did we expect these to be this popular this quickly? We have tried to increase qty with demand and the no stock problem will be a thing of the past soon. Remember we listed these in November and we didn't have a whole lot of interest and sales until around January.... Yeah well it's April and we haven't had that much time to adjust.....Lol so reliability,is every time you go to purchase boards they have no stock...
