Hi everybody! Long time lurker, first time posting. I've got a little something to show you guys! I've just built my first batch of prototypes and hope to be selling these as complete luminaires very soon. Each board has 320 LM561C S6 diodes on it for that mad diode density! I performed loads of PP...

I'm quite confused with these chinese shipping costs. I was always used to getting free shipping from China. Slow but free, and quite reliable. Even in Europe digikey has free deliveries for orders over 50e. I ended up with bridgelux as a budget solution, and I'm quite satisfied with the price comp...

Again, thanks for the input everyone. Lurked long enough but definitely been productive actually voicing some questions and concerns. So I've got in touch with meijiu and my total for 3 boards shipped to me would be 352 us (457 CDN). If I do take this route (I'm currently trying to get in touch with...

I'm also in Canada. just about finished my veg light build. once you factor in aluminum and thermal tape and what not. it's not so cheap anymore. so I think what I'm going to do for my 4x4 flower light is 4 atreum 288.2 boards as they come with the heatsink and then get a driver from digikey. shipp...

Running 3 of these boards at 200 watts each with no heat-sinks may still come out as a good viable option in all reality. An HLG-600h-48A Would allow me to run 3 boards at a nominal 200 watts each and that's also higher wattage and a nice even distribution amongst a remarkable amount of diodes. And ...

@jolly_green_giant Thanks for the arrow recommendation! I checked before and their eb strips are currently more than digikey after the conversion. However that hlg driver is a fair bit cheaper so definitely a good find. And has anybody tried those 800 boards out? Im curious everytime I see them but ...

Here in canada our dollar is garbage and shipping costs are horrific. Hence the penny pinching mentality and weighing of pros and cons that I am doing constantly. I've got carts filled with every part i'd need to complete either of these light set ups but I'd definitely like some input on which you ...

That seems like a far more likely amount, but now i'm off to count the diodes by eye to make sure. Thanks a lot, definitely helped out!

Hi all! I've crawled data sheets, delved the forum, and deep dove the googlesphere but I can't seem to come across something that seems like a basic piece of information. How many diodes are on the bridgelux 4 foot strips? Arrow advertises that there is 33 on them but I can't see there only being 33...
