Our Agile Spectrum® LED Grow Light (ASLEDGL1 – 80) has eight separate, individually controlled channels with 10 LEDs per channel that allow the user to adjust the spectrum of output light to virtually any specific spectrum required. In addition to these multiple channels, the lights can be run in a DC mode or a pulse width modulated (PWM) mode, in which the frequency of modulation is fully adjustable from 1 Hz to well over 1 kHz and from 0 to 100% duty cycle.
