The Mont-Mégantic International Dark Sky Reserve is a world leader in the use of nocturnal environment-respecting lighting technology.

While many cities across the world have converted their lighting to high luminosity white LEDs, resulting in greater repercussions of nocturnal light, the Preserve has fostered the development and installation of amber LEDs, for both street lighting and the high power lighting sometimes necessary for commercial and industrial use.

​

While more and more low color temperature LED lighting has become available in recent times, most of the market remains in the 3000K to 5000K range. Even at 3000K, the level of power commonly used results in a high amount of light pollution.

Luckily, more lighting manufacturers and retailers now offer LED luminaires with the Amber, 1800K PC-Amber and 2200K LED options.

Also, even if they are becoming less frequent, High Pressure Sodium lamps emit between 8% and 10% blue light and remain an acceptable choice.
