Approximately 55% of all sunlight falls in the 440nm range uv ir to name a couple. Artificial light can not replicate the power at the same frequency cost effectively. Consider the 440nm range as that of solar flares and other high energy solar activities. COB's do not generate energy anywhere near the levels the sun can produce.Hi. I have from my work a calibrated laser power meter, the sensor is an photoelement square 1 cm.
The meter reads directly the Watt of the light.
To measure you must first select the freqency. From 300 to 1000nm you can select any frequency you want.
You can NOT select a range.
When the sun is shining and i go out and measure the power of the sun at selected freqencys
There is so much power in the lower rang. 440 nm is 350mW. 660 it drops to 200mw
If I try to get the same power in the grow tent. I have a bunch of cxa3590
Yes i can simulate the sun. But the the plants will die soon from overlight
Even when I manage to prevent the plants of the the heat.
WHY???
