are arrays of high-performance light emitting diodes (LEDs) that are easily controllable in timing (from microseconds to hours) and intensity (from 1 % to 100 % of total output). If supplemented with the Light Controller LC 100 or Light Studio software, they can operate in multiple regimes: flash, continuous light, harmonically modulated light, or they can work with user-defined modulation. Both the Light Controller LC 100 and Light Studio software offer the possibility to create user-defined protocols with light/dark phases and precise control over the light mode, intensity and timing. Different LED Lights SL 3500 models vary in the panel size that determines illuminated area and in light color (from UVA to IR).
