There are white 3watt diodes you know, it doesn't have to be just about blurples.
Fun facts.There are HID bulbs designed specifically for growing plants, and those are the bulbs that are mainly used. So ya, there's that pesky science thing again.
HOLY SHIT STARDUST IT'S GOOD TO SEE YOU!Simply because most (not all ...see : Valoya ... ) "major" LED grow light manufacturers are designing and manufacturing their fixtures as complementary lights and not as sole sources of light for plant growth .
You see, the sole (main ) sources of light that ALL the greenhouses use ,already provide good amounts of the "green" wavelength portion of visible light ,being the sun itself or plenty of MH/HPS lamps -mainly in colder climates.
Complementary ,is the key word ...
Most often overlooked and/or neglected ,by many-if not all- "blurple" hardcore fans ...
FGS ,even NASA has "revisited" the "solid state white light for plant growth " thingy ....
Still ,you should trust and believe your own eyes and not the industry's "trend" ...
As the latter is prone to constant change ,while what you experience as "it-does-the-job-fine" is not ...
" Watt for Watt ,have I seen/experienced a blurple light outperform a white light ? "
That's the right question you should be asking yourself .
As simple as that ....
Cheers.
And osram "revisited" too......... good to see you, hope everything is going well!Simply because most (not all ...see : Valoya ... ) "major" LED grow light manufacturers are designing and manufacturing their fixtures as complementary lights and not as sole sources of light for plant growth .

the cobs have pretty astonishing lumen maintenance, and we run them even softer than that. really they are obsolete before you need to replace themThey do degrade over time a chip puts out less light
I'm not here to post facts, only what's commonly known and my opinion, that's it. If you have a problem with my opinion, then I think you have to ask yourself why that is.Fun facts.
1. People ran HID's long before horticultural bulbs existed.
2. Many growers don't use horticultural bulbs.
3. Growers that do use horticultural bulbs often do it because they last longer, not because of the "enhanced" spectrum.
You can throw the science word around all you like, but you've yet to post any actual science, or even facts for that matter.
Do you cut the silicone off chips ever ? I see people doing that and I think they must get more light but then it must mean dirt and moisture can damage your cob ? also if you touch the chip when its on with no silicone over it you must get a bit of a burn or a little zap off it ?the cobs have pretty astonishing lumen maintenance, and we run them even softer than that. really they are obsolete before you need to replace them
The germans got " derailed " from their "rock-solid" POV ? !!!And osram "revisited" too......... good to see you, hope everything is going well!
My last post was about HID, you know, the post you just quoted.We don't have to defend cobs to the death you know... I doubt cree is sending you any royalty checks.
You used HID as an excuse to defend the fact that cobs weren't designed for horticulture. Let's not be coy here.We know perfectly well why you even referenced HID in the first place.My last post was about HID, you know, the post you just quoted.
It was referenced because your statement was borderline special.You used HID as an excuse to defend the fact that cobs weren't designed for horticulture. Let's not be coy here.We know perfectly well why you even referenced HID in the first place.
It was referenced because you for some reason felt the need to come to cob lighting defense... Just like always a few rabid fan boys have to jump in to defend cobs to the death. And just like usual they don't stop to think why they feel the need to do that.It was referenced because your statement was borderline special.
But feel free to science us at any time.
Because a 5W diode costs like less than $0.10 and a good COB it costs anywhere from $12-$45 Its all about how much they can sell it to you and about profit margins.I don't think those are the reasons, but an interesting point of view nonetheless.
Sadly alot of people dont understand this graph that are not in the COB scene.View attachment 3776910
the gt3838-164 was done on my less accurate power supply as it is a 100V cob. and makes the low current data look screwy. the rest were done on my good precision 60V power supply and are pretty nice curves
Watt to watt you say??? Thats an easy challenge.Simply because most (not all ...see : Valoya ... ) "major" LED grow light manufacturers are designing and manufacturing their fixtures as complementary lights and not as sole sources of light for plant growth .

" Watt" is used as a unit to measure both electric power and radiant light power ...Watt to watt you say??? Thats an easy challenge.
For sure Im following, But Ive see what people get and Im just not impressed with the blurple is all." Watt" is used as a unit to measure both electric power and radiant light power ...
Easy challenge ?
It depends ...
Whether you want to compare which fixture is more efficient at turning electricity into light ,
or whether you want to compare which fixture is more efficient at turning electricity into buds ...
