So what you saying is a "daylight" led in the 5000k range would not be as effective as a "warm" light in the 2500k range? I love the LEDs so I'd like to stay with them but if they aren't doing any good I'll have to rethink that. I've got 9 layers and have been getting 2-4 eggs a day
Many types, including LEDs and CPFs produce "warm white" in this spectrum.
I use nothing but LEDs, even in my home.
They now come in all spectrums, essentially mimicking the incandescent bulb light most have become accustomed to.
