I received an email from Invisible Sun UK led this morning.
It's New' super efficient led chips they are touting.
LM301H EVO, also a new LH351H V3 Deep Red.
Anyone heard this was in the pipeline?

I know hlg touted a sphere report of the next upcoming scorpion with about 75% radiant efficiency. But I don't remember the spectrum being that different.

Exactly. They actually do have an agreement with Samsung even though some people don't want to accept that.

So do many other light companies who sell quadruple the amount as a tiny little company like HLG. Pull your head out of their b hole long enough to see this princess.

i think its probs fair to say hlg have an agreement with samsung that they samsung only supply the best bin diodes for use in thier boards, but they dont buy all the best bined diodes that samsung produce...
if samsung can only produce enough top bin diodes to supply hlg and only hlg they have got massive production problems or their top bin grouping is unrealistic...

Is shitshow-n-tell over? There is a few things to note on these new diodes re the photon pump being moved to 435nm:
- doing this, and getting par/watt up is quite an achievement; amount of photons contained in one radiant watt of light (or a par watt for those who prefer that) is dependant on the wave length. The lower the wavelength the more energetic the photons the fewer there are to a watt of light. So if you maintained the same electrical efficiency in a chip, but move the wavelength down to lower you automatically get a decrease in PPF/w, even though you maintain electrical efficiency. This is one of the reasons that you tend to never see n-uva or UV in serious growlights; it lowers the photon efficiency (even if radiant or electric efficiency is the same) so it's a bad move since this is the new measure for how good a growlight is; it will make your product look worse next to standard 4000k + as much 660 red as possible. Shout out to Teknik for explaining this and making light with UV even if it hurts the bottom line.

So the extra few photons were getting out of this diode actually means even more efficiency if looked at for electrical or radiant efficiency rather than photon efficiency. So double good.

435nm for horticulture: this is very interesting since it would cover more of the par region but also since 420-440 is a really interesting region in the action spectrum, it carries peaks of chlorophyll and peaks of for the stomata aperture which means you could expect plants to drink a bit better under these diodes.

A few years ago 50% board efficiency was a big deal, now we are getting closer to 75% which means getting 50% more light per watt on your cannopy.
Personally I'd like to see these new Evo combined with regular diodes in order to get a wider bluepeak.

Hlg would get the best bins of newest Samsung diodes but for every top bin diode there's plenty of lower bin diodes that gotta go to someone's

HLG gets the same product everyone else does. Anyone can buy the same diodes. Maybe not directly from Samsung but HLG more than likely goes through a wholesaler rather directly from Samsung. They don't have any special agreement.

The LM301H EVO will be available to anyone that wants to buy it. It's not exclusive to Invisible Sun. The way the supply chain works these lighting companies are buying from bulk wholesalers and not directly from Samsung.
