Buying knock offs, copies, or simply any "unbranded" led lights for 70-80% price of branded lights is plain stupid.
I first dont have money and cannot afford high end lights and prices but still.....
If i can buy something similar to kessil, red sea, radions, prime, philips.... For 20%-30% of price, then it is worth to consider this product, it may be not great product, but it will work, i need to adapt my expectations and all good.
But, between 250-300$ unbranded, and 400$ branded, that is no brainer, 100$ may be serious amount of money, for me it is, but, i learned in hard way, its not worth. Rather buy slightly weaker light (50w instead of 90, 90 instead 120w), but, even weaker, branded light will be better, provide better coverage, better spectrum and overall better light.
I am for cheap alternatives, love black box, love my rs90,i'm totaly for diy, dont need fancy app, but, lets be real, it's all sub 100$ lights.
So, any light below 100$ is great light, i can survive all flaws, cutting corners here and there, poor quality, give it to me.... But, paying almost full price, really not worth....
Dont mean to be rude, but all of those lights, no need to list all of them, is simply 100$ max units. Not 200, not 250, not 300$... Below 100$.....
