Dark Sky LED lighting.
Making the stars shine brighter for you.

Why Dark Sky?

If you look up at the sky late at night, the chances are, you won’t be able to see that breathtaking view of myriad brightly shimmering stars scattered across the endless void of the cosmos. Maybe some intently glimmering ones, but that’s about it.

The culprit responsible for that shocking theft of aesthetic pleasure is lighting pollution.

Vastly present in big cities, light pollution causes more negative implications than it might seem. Besides hiding away the beauty of the night sky, it also interferes with the work of observatories, and negatively impacts the wildlife.

Best of Both Worlds

A range of our products is available with a Dark Sky option: the Dark Sky compliant products are optimized to preserve the night sky without affecting the light quality on the ground.

These fittings are equipped with a special hood or a banner around each LED plate, minimizing scattering of the light and focusing it on the ground where you need it.

Colour temperature

In addition to the special hood, the Dark Sky fittings feature optimized CRI.  For example, below are the recommendation currently active in Chile, one of the world's leading Dark Sky advocators :

  • No more than 15% emission between spectrum 300 to 380 nanometres ; (Ultraviolet)
  • No more than 15% emission between spectrum 380 to 499 nanometres; (CWT – blue)
  • No more than 50% emission between spectrum 781 to 1.000 nanometres. (Infrared)

Always consult your local laws and regulations to improve your practice and ensure full legal compliance.

Installation and proper optics

Installation is very important for Dark Sky compliance - the angle of installation must be 90 degrees facing the ground. To focus the lumens where we need them to, asymmetric optics BW1, BW3 are preferable and the AS4 optic is ideal.
