So basically in 3-6 months you have the same light? Is that what your sayin or do he lower grade deteriorate as wellSorry, I'm chiming in between drives.
As an example, normal lm301b specs are:
Luminous Flux: 39.3 lm @ 65 mA
Top bin would be 40 or 41 lm.
Anything under 35 wouldn't pass QC. Thus wouldn't be sold.
Even if you have actual top bin, you're talking the difference of less than 5% if not more like 2%. And that vanishes after about a month of use.
This is how I understand it. Been working with LEDs for years.

your not JOKING at All... I'm Sure you guys are trying to see whats up............. I'm sure 100% Mar's Does Care about them and there place in the Led Market......... If not you should be cause they put out GOOD Stuff.........Sorry, That's just a joke. We have no plans to research other Chinese LED companies products, our R&D department is busy on the new products, no time
Actually, no other community growers mentioned them except on here, so we don't pay much attention to them so far... Thanks for your concerns, we will keep eyes on themyour not JOKING at All... I'm Sure you guys are trying to see whats up............. I'm sure 100% Mar's Does Care about them and there place in the Led Market.........

I'll be watching........>>>>>>>>Can't say much yet, stay tuned!
Where did you learn this? Would be nice to have a source.
I wonder if they are still making the 301b's, and since everyone is going with the 301h's..except the knockoffs..who gets what?IM struggling to find my source. It was based off what I believed to be true, but just waking up I’m completely blurred. It was an article on how different vendors get different quality diodes based on their place in order line or something. But it came down to the fact that some vendors where buying lower quality , and not stating it. In manufacturing its common to produce several quality forms on the same line and only after basic testing is the actual quality stamp given

yes I Need More Light's and Can't afford to buy any right now...... so I would run a Mar's light at this point.......
The builders in the riu threads say that they are exactly the same diodes. I dont know what is true as i have not researched myself but the guys saying this run hlg and other led companies.
They seem to be the same diodes.
The h is just mostly marketing, but also added specs in the data sheet for horticulture use.
If you read over the data sheets you will see:
Lm301b
Tech Spec
Wattage0.2 W Forward Voltage2.7 VLuminous Flux39.3 lm Luminous Efficacy223 lm/WCondition5000K, 65 mA, 25°C
Lm301h
Tech Spec
Wattage0.2 W Forward Voltage2.7 VPPF0.55 μmol/s PPE3.10 μmol/JCondition65 mA, 5000K, CRI 80
Wattage is the same, forward voltage the same. Conditions are the same so we can compare them directly. If you run the numbers through a lumen to par calculator 39.3 lumens = 0.55 μmol at 5000k
So as far as I can tell, they are the exact same chip. The H designation is so the datasheets have the required information for the horticulture guys.
That's how I see it. I'm sure Samsung would answer if we asked them.
Come on they will give you a 3% discount!!! If ya buy one !!! LmaoFREEEEEEEEEEEEEEEEEEEEEEEE.......................................
I'm not Buying a light from Mar's
I'll Pass on that Deal ty Very Much....Come on they will give you a 3% discount!!! If ya buy one !!! Lmao
