Very informative thread
Can't contribute much to the thread other than sharing my experience.
Years ago i purchased my first led light when they became a thing but it was a very bad experience. It was blurple light, had 300W power outdraw, cost me 500 bucks, created a hot spot, wasn't much cooler than using hps with an adjust-a-wing reflector and couldn't compete with it in any way despite the advertising.
So this time i wanted to make it right when investing so much money and did a lot of research before my purchase.
My brand of choice is Spider Farmer. Their SE 5000 model with 480W is what i use for late veg and flowering all year round. Really like the stepless knob for the power draw and that i can put the power supply outside the box in summer and inside again in the winter to blow a fan on it and gain some degrees.
The results are also working for me and that's why i got a Spider Farmer SE 3000 (300W) for my veg/mother room to replace the Viparspectra P1000 (100W) for now and maybe using it for smaller projects in the future.
Is Spider Farmer the best? Probably not and i don't know but i got my money worth.
Hope this helps somebody in any way and maybe i should mention that the Spider Farmer Halloween Sale will end today and that i am in no way connected to them, just a happy customer

What nm is magenta?

Its purple/magenta in your eye, plants are very apt at differentiating between true violet and blue+red mix.

Anyone try the Valoyas? https://www.valoya.com/medical-plants/

They've done tons of research specifically on the effects of different light spectra on Cannabis.

The Effect of Light Spectrum on the Morphology and Cannabinoid Content of Cannabis sativa L.

The morphology, inflorescence yield, and secondary metabolite accumulation in hemp type Cannabis sativa can be influenced by the R:FR ratio or the amount of short wavelength radiation in a spectrum

It's a local company, but I've heard that they've actually declined to sell any gear to our growshops.

I understand their choice in this, though - even our hemp breeders are and hemp processors are constantly being bombarded by the local officials with their bullshit inquiries and awful hysteric decisions.

EDIT: Personally I've used HLG LEDs for about six years now, and I have no complaints. The lights still work 100 %.

Exactly. I'm just poking fun at the spectrums. Red/blue are at opposite ends.

I guess you can say we 'see' it as blurple. Our brains do some funky stuff.

About time somebody bring up Valoya! They seem to do excellent work around spectrum but for all my posting and forum nerding ive not met anyone who uses their full on experimental spectrums.
They are Finnish, right? Hej från en Utlands Svensk, som blev temporärt tvingad tillbaka :/

Ive forgot about them and will review those papers, on initial view they seem really interesting but i can see a few missing details in their approach.

What nm is magenta?

Hear me out, hear me out..

With data on hand...

Should be 428 in a fucked up kind of way ?

Samsung LM301H EVO​

This is the LED diode spider farmer is using in many of the latest 2024 light fixtures
Its arguably the best of the horticultural top class products available at the moment
IMO thats where im at for residential lighting,


Anyone disagree/agree and why ?


Think this would be a educational discussion at this point.
Will add one observation I piked up along the way while this thread ... here it is!!!
There are other producers of LED fixtures who are able to tweak the efficiently numbers, here how
What they are doing is adding a ultra high efficiency red spectrum light for the flowering spectrum

While it does appear the numbers are fudged a little it seems effective and legit.
Adding those extra reds or red bars may be a benefit in flower.

What say you?

Surpassing the capabilities of both the Samsung LM301H and LM301B LEDs, these EVO LEDs redefine plant growth enhancement. With superior light quality and an increased light output per LED, they harness a more potent blue spectrum, all while achieving a level of efficiency unattainable by non-EVO LEDs. Veg footprint is 3 x 3 ft, Flowering footprint is 2 x 2 ft.
