If you are talking about hlg ppfd maps they pay for outside testing. Its accurate. Most everyone elses is not.

Yup... why you need the real data... can usually find someone testing on you tube.

So, back to the point I was getting at, is that a balanced spectrum with relatively equal blue and red spikes is where the current high performance LEDs are at (and, yes, far red supplementation).
Like aqua said, blue will make them short but so too will red, come flowering... when we want to minimize stretch and also get that nicely packed bud structure.
The big issue with LEDs (except COBs) is intensity and penetration, so, generally, the shorter the plant, the better.

Funny how it comes back to that. Thats the reason i use MH in Veg and HPS in flower, among a couple other reasons.
Although penetration has never been an issue with 1K HID Lamps. Its about the only thing they have left going for them it seems.

I am learning about Spectral Analysis now for a few Years and how Cannabis behaves Blue Light for Short internode Distance Squat and Bushy plants
+ High in Red --> Induces flowering (in combination with 10h uninteruppted Sleep + 2h activation PTR + longer elongation more leaf less Budzones
Far Red makes the Plant sleep faster as well as accelerate Photosynthesis overall (about 1/6 or even 1/10) Far Red To Red Emmerson Effect
IN my mind that spectral Graph is to good to be true with that last one Bump at 660nm which is very important and LEDs drop off faster :) (Phosphor Coating is not perfect)
I would Recommend lets say 400W Scalable System = 180W 8000K LED + 180W 2700K(something (HIGH RED) LED + 20W Far Red LED + 20W UVB CFL
If links are allowed if i would build my own a new lamp with least hassle possible :)
Nichia NFDWJ130B-V2 Chip on Board Modul, 6780lm, 2200K, CRI 80
Thats what i would use + 8000K or 6400K equivalent
that chip would cost me 14€ for 44W of nichia led which is optimized for growing too :)

No idea how I would even begin to do that.

Ya that's where I found the data for the viparspectra xs and p. Which according to that is way better than the hlg ones.

You have to be really careful with shit like You Tubers. If you get the chance ask them if they are sponsored by the who ever they are reviewing. You have to really do your homework specifically with lightning. A couple months ago some newbie came on here with some POS China light and I straight up asked him if he was sponsored by the manufacturer. After receiving a few F bombs from the guy he never came back. I can only assume he was sponsored.

Independent YouTube? Can ya link because the new HLG diablos are by FAR the most efficient on the market... absolutely kill everyone else including gavita.

I bet they are testing different wattage fixtures.

Or don't have a clue what they are doing and mismatching fixtures.

Always co pare on a watt to watt bases

It's really hard to choose a good light because I have such a small tent, the actually good ones are much too bright and are made for much bigger spaces. But the cheap ones have a bad spectrum and aren't as efficient but somehow much more expensive for what you're getting.

My Recommendation would be some kind of active Cooling (As i am a PC Hardware nerd too :D i use my PC fans from Akasa Viper can keep everything cooled down with pressure or verry silent still efficent.
i would use in your scenerio leds without lenses so you dont burn em by concentrating light and throwing it in the small room which is verry efficient :D
If you go mad go for some good COB lights both high and low Kelvin some pc CPU cooler on the back and DONT ADD FAR red for groth control as well as lots of Blue and UV for Resin an terps :D
you could as well use the walls as added lightsource like strips of 660nm and 630nm Red +440-470nm Blue less power less burning but bedder illumination and less larf buds

I would not trust the information provided by that website. If you take a look at the lights he is testing they are all coming from china from a quick glance. Growers Choice are Chinese but an American Company. I only know that because I had to get a replacement light after 6 months of use. That is the challenge with grow lights today. There is so much bad information. Just go with HLG and you will get happy. And for the record I do not own nor am I sponsored by HLG.

after seeing @sshz get 3 pounds the first time with the new gavita i am not defending hps with you any longer. ;-)

Lets say get 8x Intel Stock coolers with copper core (preferebly)
+some power supply 12V is good cool louder 9V optimum
/ +or Bedder a fan controler with a "volume turner" optimal sound to cooling
+ get 4x 2200k chips and 6500k chips
+ Arctic silver thermal glue (wear gloves sticky silver lol)
+Power supply should be a Constant Current Device in this example 44Watts / 39Volts is = 1.13Amps
i would recommend using something like Constant Current with (Little cooler more longlivity) 1000ma = 1A and 39x8 = 400 Volts of capability range of power supply
My first led i have mady by hand with costom color 5W Star Chips and costom made cooler looks frankenstein + copper :D
Wear Electrical protective gloves never work on powered curcuits and keep the protected constant current power supply :)
ps check out Apogee Instruments Bruce Bugbee Light Spectrum about of 40min of dank information :D

Hell i would grow with any of those Chinese fixtures... I just wouldn't spend my money on them because I feel there are better options. Exaggerated or not I lose some efficacy and life of product would be a concern... but I would absolutely be able to grow just as good of a product.... maybe have to run em closer and more for coverage but they will absolutely work. Its just the absolute lying and misinfo that pisses me off. But use a par or lux meter and just adjust to the intensity needed... the plants won't know the difference.

its migro. He is a light manufacturer and seller that tests everything. But not sphere test. Just hangs a par meter in a cardboard walled square. Does a good review though. Pretty comprehensive.

Same wattage light? He is usually accurate so im betting the wattages were different. Or an older hlg vs the new viparspectra.

@ Aqua Man is there a problem with using a lux meter with Burples?

Why add more power for no more light? A higher efficacy light with a good heatsink. IMO if you need forced cooling for a light I would walk right by it.
