Is that a Maui standard outdoor light?
Many won't realise, but Maui, in Hawaii, have implemented outdoor lighting regs, that limit blue content to 2%. We can expect to see this in other places soon. The blue is keeping us and nature awake, and is the main cause of the glow in the night sky from lighting. This is leading to lights 2000K and warmer being developed. Which I welcome, as a car owner, who wants street lighting and car lighting, to be different colours, again.
I know we have some pretty good LEDs for this job, but have not seen any that offer over 185lm/w. Which is a bit like a very good 3000K with the blue lowered, but no extra output of the other colours. This leads to little net difference in flower weight, as the 11% blue reduction, increases yield by a similar percentage (I have not done the exact maths, but I think 15%, giving 4% more bud weight)
What we need is less blue, to lead to more green. That will help them with colour temperature, while helping us with yield. Green seems to only be 5% less use to cannabis than red, so we could work with that.
This is a bit academic right now. A better area to pursue, is far red. Where adding 1w of FR to the main lighting, is like turning your lights down 3w. Presuming we grow cannabis.
No, It's just a regular outdoors Samsung LED , I just come from a time when 2000K was determinant of bud density and resin richness, and I simply applied the same concept to LED after analysing their spectra.
EDIT: I used that specific Samsung LED because it was the only 2000K white LED that was commercially affordable for me.

I have not seen a 2000K white LED, except in prototypes. At the moment, filtered fittings are being used. Perhaps your light predates these regs, and has a touch more than 2% blue.
Here is a Philips 1900K with 1.8% blue. Made for retrofit, though I can't get one..
They do 3030 and 5050 sizes, in these nightscape offerings.
Other manufacturers will be gearing up for production, as more places adapt the new regs. I'm not sure I will see them in the UK though, as it's the cri of LED street lighting, that's taking us towards net zero
Perhaps they are of use to you, as their must be something we can get (by now)

I don't think you are off topic, though I might not of been clear. These lights don't apear to meet the 2% blue requirement I was talking about, and linking to. I did acknowledge you have a 2000K light, but that it probably doesn't meet the bill either. Though initially I thought you may of found one, which sparked my interest.EVOLEC 50W LED FLOOD 4200LM C/W PHOTOCELL, 2000K SON EFFECT | TG40-50W/2K/PC

New Law Will Make Maui Turn Down The Outdoor Lights To Protect Wildlife
The ordinance was passed due to concerns that bright, onshore lighting confuses seabirds and endangered sea turtles.

oh , shit, sorry, I really misunderstood you there
because I didn't read the whole message,
please find it in your heart to forgive my brain fart
Yes, [EDIT]: mine are cheap 2000k, they are in the CRI 80Ra (and even lower likely) range and very likely like you say
EDIT: for all i know I might have acquired a scam, but it does have the "reddest" white in my LED lamp collection.
sorry [EDIT 2:] and it might actually be because of the extra blue coming out that my buds have been getting foxtails....

Those lights are huge, what's there dimensions?
@cfl...KING Same size as the Cheap LED we have. 6 or 8 bar LEDs are that size.
That's one of the things I like about the hlg diablo it's only 3x3' can fit them in with a mix of hps easier
