The last setting, relax, is a cosy 3,000k and is meant to mimic the light at sunset. However, it dominated our laptop screen’s brightness, which probably isn’t ideal. We were dubious about this, but we did find it made us feel a bit more alert and focused when we used it while working. The active mode is a warmer 5,000k, and is designed to help you concentrate. We can attest this feels very brilliant and definitely made us feel, well, sunnier after using it. This mimics midday light, and the lamp is meant to be placed about 20cm from you for best results. Looking first at the therapy mode, which is what we’re really here for, the brightness is a cool white light that is about 6,500 kelvins (k) – kelvins relate to the temperature of the light, if you’re interested.

Whether your symptoms are moderate or severe, SAD lamps can help manage them by providing you with a blast of light. The severity of this reaction can vary, and that can lead to a diagnosis of seasonal affective disorder (SAD).
