Soraa Launches Blue-free, Sleep-friendly LED Lamps

Lamps combine an engineered mix of green and red phosphors to produce a spectrum with a wide gap in the blue range

Soraa, best known for its full-spectrum LED technology, is now introducing a series of lamps that emphasise health and well-being with the world's first completely blue-free LED lamp portfolio dubbed Soraa HEALTHY.

Soraa HEALTHY products feature patented Zeroblue technology, which means they emit a blue-free spectrum reducing melanopic lumens by ~40 percent compared to conventional LEDs - and without suffering from the yellow cast of other sleep-friendly LEDs.

Soraa says that when used in conjunction with its violet LEDs, the HEALTHY products combine an engineered mix of green and red phosphors to produce a spectrum with a wide gap in the blue range, removing blue completely while retaining a high quality of light, resulting in vibrant, natural white light and colour rendering.

The sun emits blue light naturally in the morning, supporting productivity and alertness. As the day progresses, daylight naturally carries less and less blue, prompting the body to prepare for sleep. However, people are increasingly spending most of their waking hours indoors and under artificial light, running the risk of blue light overexposure during evening hours that can inhibit restful sleep.

Soraa HEALTHY lamps help the body better recognise that the day is ending, thus aiding the natural steps of a healthy sleep cycle.

“We know blue radiation wakes you up in the morning, getting you ready for the day, but it can be problematic at night as it interferes with our circadian rhythms and inhibits sleep - a common side effect of too much artificial blue light exposure,” said Soraa chief scientist Aurelien David,.

“At Soraa, we believe light has a strong impact on our everyday life, and we cannot compromise the quality of light,” David said. “We developed blue-free products to provide a light source that is healthy at night and respectful of your sleep cycle without sacrificing colour quality.”

Soraa co-founder and board member Shuji Nakamura, who received a Nobel Prize in Physics for inventing efficient blue LEDs, advised the creation of Soraa HEALTHY LED lamps.

“We are entering a new era of healthy lighting options,” Nakamura said. “With the introduction of Soraa HEALTHY products, a first of its kind, we're now able to more directly and positively impact the support of proper circadian health. Soraa's introduction of blue-free lamps will transform the way people think about light and the impact it has on our daily lives,” Nakamura continued. “Blue-free solutions are just the beginning as we continue to develop advanced, dynamic lighting solutions that most closely match light found only in nature.”

Soraa HEALTHY 120V A19, MR16, and GU10 lamp shapes are now available.

Soraa HEALTHY luminaires are expected to sample in late 2019, providing even more opportunities to introduce the benefits of blue-free light to a wider variety of commercial interiors.
