The Arctic Beam Remote Lighting Control System enables ski operators to monitor, switch and dim Arctic Beams individually or in groups. The control system is easy to install, deploy, operate and maintain. The system was specifically tested in misty conditions and hilly surroundings. The Arctic Beam Remote Lighting Control System software can be accessed through a web browser that supports Microsoft Silverlight on a Windows or Mac computer, and through any tablet, Ipad or smartphone with the use of the Slope Lighting Solutions app. With the remote Lighting Control System and a smart phone at their disposal ski slope operators can create a lighting experience that is unprecedented on ski slopes.
HIGGER EFFECTIVE ILLUMINATION
The Arctic Beam generates more useful lumens to the eye than other lamps. The reason is that the human eye is more sensitive to the wavelengths emitted by the Arctic Beam than
to the wavelengths emitted by gas discharge lamps.
There are two light sensitive components in the retina of the eye, rods and cones. Rods give us our night vision capability (scotopic) vision, while cones give us our daylight (photopic) vision. The chart shows clearly that the light emitted by the
Arctic Beam falls within the scotopic sensitivity of the eye – most of the light emitted by gas discharge lamps (SONT(t) spectrum) falls outside of the scotopic sensitivity.
The ratio of scotopic luminance (or lumens) versus photopic luminance in a lamp is called the S/P ratio, which is a multiplier that determines the apparent visual brightness of a light source
as well as how much light a lamp emits that is useful to the human eye, referred to as visually effective lumens (VELs). So to get the visually effective lumens of a light source we need to
multiply its specified lumens with the multiplier for that light source. The S/P ratio for LED is 2,1, for low pressure sodium 0,38, for high pressure sodium 0,58 and for HID metal halide 1,49. A higher S/P ratio provides higher visual brightness
and sharper vision.
BETTER COLOUR APPEARANCE
With a minimum colour rendering index (CRI) of 70, the Arctic Beam makes colourful ski outfits and gear appear natural on the slope. Gas discharge lamps - with the exception of metalhalide lamps – have a very poor CRI which causes objects to lose their natural colour andbrightness.
NO TOXIC ELEMENTS
The Arctic Beam contains no hazardous chemicals as opposed to Gas discharge lamps that contain mercury which is toxic when released into the environment. To dispose of mercury requires special care and precautions.
DIFFERENT COLOUR TEMPERATURES
The Arctic Beam has two standard Colour Temperatures: 4000K and 6000K. 6000K is preferred because of higher efficiency and higher brightness and visibility. However there is scientific evidence that bright light with a colour temperature well above 4000K can have negative effects on animal nightlife, such as disturbed rest periods, disorientation and a restricted radius of action. This is why in some countries and areas guidelines and laws have been formulated that restrict the colour temperature of luminaires for nighttime illumination to 4000K or lower.
