I cannot for the life of me find the spectrum for this chip at this Kelvin. I had 4x citizen clu 048 1212's 80 cri being driven at 60 watts a piece I know the cxb3590 90 cri 3000k chips are heavier in red then most but don't know if their a straight up swap for my citizen 1212s And I can't find the ...

Perhaps Tekniks comment on the comments was a little exxagarrated. There are videos advising on how to avoid fake reviewed products on alibaba, and there is no shortage of dishonest reviews. This does not mean that alibaba would have any interest in stopping real reviews. The final product is neith...

You'll know after you have spent a year buying shit from aliexpress/alibaba ;) Some sellers go to great lengths to have positive reviews. I bought plenty things that I'm happy with, but teknik is not wrong. If all the buyers of some of these lights were forced to review it 1.5 years later, you migh...

https://www.rollitup.org/t/wasted-my-money-with-kingbrite-heres-why-you-should-buy-from-digikey-instead.997255/ That MMED grower is full of shit. I ordered 2x360 watt kingbrite qbs 2021 versions and when they arrived 2 of the panels had rows of diodes that didn't work. They sent me 2 brand new pane...

Brand new here with a big question. So I've got an HPS, CMH, COB\blurple, and a KINGBRITE QB with lm301h diodes all in the same tent This is my first grow and im trying to educate myself as much as I can my first time OK, I'm going to ask the question that no-one else has: How on earth did you end ...

Not sure why you trust any Alibaba reviews as they are not real. I almost agreed with you until I wrote my own review and it was published immediately Screenshot_20190927-171150_Alibabacom.jpg So that means they have 5 out of 5 stars on 300+ reviews, and their real. Definately a worthy supplier to ...

@MackMuurder Without going into too much detail regarding color binning, if you read the data sheet properly you will see they have 3 brightness values for 3000K, they also have 3 voltage values. 1,000,000 ÷3 = 333,333 333,333÷3 = 111,111 That's before the MacAdam ellipse binning which HLG would pr...

I belive that Samsung can not produce enough top bins and HLG take them all, so anyone claiming to be using the top bins is full of shit. Out of a production run of 1 million LEDs there are usually only about 80,000 top bins. HLG would be ordering over 5million LEDs from Samsung per order so that d...

Decent knocks off grow really well, HLG pays extra to make sure they have the most electrically efficient LEDs, Bins can make a difference of upto 15%. With Samsung mid powers it is about 10%. Not sure why you trust any Alibaba reviews as they are not real. Your choice what you buy but you will oft...
