and what we could do. Virtual Sun is something we believe people will get value from, something that can be used all the time.” According to Innerscene’s measurements, Virtual Sun’s UV light component is approximately 0.41µW/cm 2 with 10 000 lux at the surface, which falls off exponentially with distance until it is essentially non-existent. Virtual Sun is also safe to use near sensitive art pieces like paintings, photographs and sculptures, and it falls within the parameters of UV radiation suggested for artefact conservation. “When our team tackled the challenge of matching the sun’s brightness, they started implementing the colour changes in our circadian rhythm setting. We wanted a blue sky and the sun,” explains Clark. “If you measure the colour temperature of the sky without the sun, it’s 40 000K on a clear blue day, but most LEDs don’t go over 6 500K, which is like an overcast day if you had it in a panel format. Once we combined multiple LEDs, it was easy to get any colour temperature we wanted.” The CEO adds that testers “felt” a difference under a blue daytime sky compared to warmer skies of later evening. “It’s amazing to feel what 20 000K or 40 000K feels like compared to 6 500K. It’s like you’ve had an extra cup of coffee that day – it really wakes you up and gets your body going. That is essentially what we wanted with this product. It can be used in any application, from hospitals and factories, to homes and offices. Sunlight is important and Virtual Sun can recreate that where sunlight isn’t possible.”
