Still no independent review of the GeekBeast Pro???

Tell me why the LM301h chips are more expensive than the LM301b chips, what is the difference between them?
 
The B and the H are identical for all purposes but for the H they only chose top bin chips.
The sulfur protection exists on both chips, but is marketed on the H line. Its just a case of marketing and a slight difference in how they measure light output and bin them.

Check it out in the samsung webpage/datasheet. I think SK is top flux bin in 3000k.
There is also a voltage bin. The best diode has top flux bin and lowest voltage bin: more light for less watts. If you got it on alibaba there is very little you can do re actually confirming that it really is top bin.

So buying on the USA site will not give you LM301h
But on aliexpress there is a choice

With geekbeast, meijiu, kb etc youre gonna get what youre getting, i dont see there being any real difference in this case. Its the same diode, and of undeterminable bin as from an ali/china supplier so id say its the same.

Okay, but for some reason they (chips) are $38 more expensive.

Seems more likely, but not guaranteed, that youll get top bin buying the H. On the other hand i dont think it matters that much. A well distributed growlight should be able to handle a 4x4 at 600w no matter bin.

Yes, you are right, but if there is a selection of chips on the site, you can try to take it at a higher price, it won't get any worse :D
