Temporal light modulation (TLM) is defined by the International Commission on Illumination (CIE) as fluctuation in luminous quantity or spectral distribution of light with respect to time.[1] The effect is typically connected to lighting products such as lamps and luminaires where the light is modulated in order to provide some functionality, such as dimming or color change. TLM can cause temporal light artifacts (TLA) such as the stroboscopic effect or phantom array effect. TLM has been linked to headache and migraine, and in rare cases epileptic seizures. [2]
