Led Relative Spectral Power Distribution graphs

[DankaDank]

Can somebody please tell me why there is the absence of various data regarding kelvin ranges of the CXB3590 on relative spectral power distribution graphs, such as the 3500k,6000k,6500k and others.There is probably a good reason for it.

Another point according to this graph is that if i where to buy some 5000 k's for veg it would be retarded because the 4k has the same spectral power (in the blue area) as the 5k, while the 4k is higher from
470 nm's onwards as well.

Just realised while typing this that it would be nice to have a thread with different graphs relative to spectrum of any leds from little 3 watt diodes to 1000watter cobs.
So feel free to post shit !

Probably because cree doesn't manufacture these chips to grow plants...they manufacture them to light warehouses and driveways....the fact they grow plants is just a pleasant side effect of their work.

strain dependent strain dependent....oh sorry carry on, I get verclemt sometimes

not true, multiple graphs have been overlaid relative to each chips peak (100%).
But the peak for each in absolute terms is different.

Thank you very much that makes sense ,i didn't mean for it to sound like a statement, i was hoping for someone to agree or disagree and tell me why.

This is more of an actual comparison. You can see why the 5000K CRI 70 makes a very good veg cob...I have 6 of them myself...and the plants love them.

cutter has spectrums for some not on the datasheet

3500K
