Educate me. The whole reason I’m here. Why will the HLG do better than the Hygrow / kingbrite / alibaba specials. Is it how the boards are wired ? Amount or diodes / LEDS ?
Whether you will see a difference in performance is a good question. I think a few people have done side by side comparisons before and they came out pretty close.
The difference is HLG contracted directly with Samsung, and have their own production facility in the USA where they make the PCB boards. So they are guaranteeing a higher quality product that has passed QC checks, and they are transparent about the manufacturing process, and components used.
The knockoff clone boards are using an exact replica design for board layout, and they *say* they are using the same diodes, but the reality is that you don't know. If you look into 'binning' they could be the same part number, but a lower grade that didn't make the cut. They have to save some $ somewhere, and if they are dishonest enough to use HLG's brand name and marketing to sell their product, I can pretty much guarantee you they are cheapening out elsewhere. If not the chips themselves, the solder, or some other part.
Let me put it this way. Say I bring my motorcycle to you for service. Sure you can use knockoff non OEM parts to save a few $. They might perform just as well. However if I am spending money and don't want to take short cuts, I am willing to pay the premium for the real thing. Especially if it's something I want to take care of and make last a long time. Non OEM parts might last just as long, but chances are they will fail sooner, and in worst case can cause new problems.
I also asked early on, if you had designed some new better motorcycle component, and put years and lots of $$$$ into getting it to market, and came up with a good name like Sickboy Filters or something. Setup a factory to do production in the USA, and all the tooling required to produce them at scale. And then someone from China came along and copied your design, and then started selling copies for 1/2 price using your name and marketing info. Be honest, would you be cool with this? If not, then why is it cool to do to Stephen from HLG?
