Ok, it seems to me that we look at this from wrong angle...
We all talk original vs copy, but....
Lets start from beginning.... When manufactured, any led light, no matter where is produced, by who, is 50$ product. (don't quote me on exact value/cost, this is for illustrative purpose)...
So, 50$.... where in hell they find 500+$ value?
Simple..... As soon as this product is put into some fancy box, and on it someone print label "radion", "philips", "ati", "whocareswhat".... all of sudden, it's 200$ product.
In that difference, you pay a) name, b)warranty c)marketing. Another 100$ goes to software, aka app to run that unit.
So, here we are at 300$.... add taxes, add profit for someone who sells it in retail, and voila 500+$ light.
You pay for name, you pay for any possible future problems, warranty, replacements, no matter will u ever need it or not, someone will, companies don't replace units because they are good in heart, that replacement cost is already calculated in cost that end user pay.
One thing is also calculated - marketing, promotion, free samples to reefers, youtubers, celebrity, who will, then, spread the word around world, preaching gospel about "some company some product" superiority.
Chinese, or any other company simply don't do that..... They are requesting leap of faith from buyers, to cash out some more or less serious money, and try for themselves that product.
Is the product good? Is it better than "some company some product"? Is it total garbage? Nobody knows, there is no serious amount of happy or unhappy customers, no trustworthy source to tell the world about this or that product.
Even if it's a copy, rip off, it still can be better 10 times, cheaper 10 times than "some company some product". Why not? Really, there is no reason.
But again, who would trust me, or some random internet dude, who claims that this is superior and cheap product?
On the other hand, all u need is one "reputable" person, who newer seen or use such product to say "hey, its Chinese copy".... and, public opinion in second swings to "garbage" end of scale....
If some Chinese company, or any other small manufactures goes this route, and give 10,20,50,100 units to some random people on forums, YouTube, to do honest review, test, and when reports of these people are available, then we will know, at some degree of certainty is this product good, bad, or just ugly
One, two or three people who take leap of faith and purchase some product simply don't have credibility versus army of "some company some product" fans/users.... for waste majority of reefers, that is...
Of course, some random manufacturer will not take this route, they goal isn't to sell gazillions of units, or even produce that number, they are happy with 10,20, 50 units that they advertise on ebay, alibaba, or some similar site... when, and if all of them is sold, they will make another 10,20,50 units, and they are happy....
