Dark skies are defined by the Oxford English Dictionary as:
“Places where the darkness of the night sky is relatively free of interference from artificial light."

From 1993 to 2000, light pollution in England rose by 24%. As a result, fewer than 10% of the UK population can currently see our galaxy, the Milky Way.

What Are Dark Skies?

Artificial light can greatly disrupt the ecology and behaviour of nocturnal animals, affecting their natural rhythms, diet, and sleep patterns. This disruption is especially harmful to endangered or threatened species.

Therefore, it’s crucial to design lighting that minimises negative effects on wildlife, ensuring their survival and preserving their natural habits.

Biodiversity and Dark Sky

Our luminaires lead the way in reducing light pollution. Carefully designed to minimise upward illumination and glare, they protect local wildlife and preserve the environment.

With Dark Sky lighting, Tamlite is committed to creating ideal outdoor spaces, promoting responsible lighting choices for a brighter, greener future and a balanced night sky.

Reducing Light Pollution

Dark Sky International (Formerly The International Dark-Sky Association) is the leading authority on dark skies and light pollution, spearheading global efforts to combat light pollution since 1988.

As the foremost organisation in this field, Dark Sky advocates for solutions that enable people to enjoy the beauty of dark, starry skies while benefiting from responsible outdoor lighting.

The Five Principles for Responsible Outdoor Lighting

dark sky icon 1 Useful All light should have a clear purpose. Consider how the light will impact the area. dark sky icon 2 Targetted Use shielding and careful aiming to target the direction of the light beam. dark sky icon 5 low level Use the lowest light level required. Be mindful of surface conditions and reflections. dark sky icon 3 controlled Use controls, like our Vision Air, to ensure that light is available when it is needed. dark sky icon 4 warm coloured Limit the amount of shorter wavelength light to the least amount needed.

What is Light Pollution?

We often think about pollution in terms of air, water, and land, but light can also be a source of pollution.

The excessive or misdirected use of artificial light, commonly referred to as light pollution, has far-reaching impacts on the environment, affecting humans, wildlife, and even the climate. Sources of light pollution include lighting on buildings, billboards, businesses, offices, factories, streetlights, and illuminated sports facilities.

Sadly, much of the artificial light used at night (ALAN) is overly bright, misdirected, poorly shielded, and often unnecessary. This light, along with the energy consumed to produce it, is wasted as it escapes into the sky rather than illuminating the areas where it’s actually needed. There are four main components of light pollution that are Dark Sky recognised. GLARE | SKYGLOW | NUISANCE | CLUTTER
street light glare on road

Glare This is the uncomfortable brightness of a light source when viewed against a contrasting darker background. In less densely populated rural areas, glare will seem relatively more intense than in urban areas. This is particularly noticeable when looking from raised viewpoints into the darker landscape below. SKYGLOW This is the brightening of the night sky which can be seen emanating from the horizon, originating mostly in built-up areas. It is caused by badly directed light sent above the horizontal and scattered by aerosols and particles in the air. It can also be reflecting from surfaces. Light that travels near the horizontal is the most damaging as it travels furthest through the lower, denser atmosphere. This can be avoided by ensuring that lights are directed downwards where the light is needed. nuisance street light shining on houses in street NUISANCE Sometimes called 'light trespass or intrusion,' this involves light spilling beyond the property or area being lit. Although this pollution generally relates to windows and intrusion into private property, the term 'light intrusion' also applies to natural habitats and areas of high species interest. light clutter for dark skies CLUTTER A fourth consideration - Even if a lighting scheme were designed that avoided sky glow, intrusion, and glare, there still exists the possibility of significant impact on dark and sensitive landscapes and wildlife due to the mere presence of the lights. When the presence of lighting itself creates negative impacts, alternatives and re-siting should be considered.

Precise Optical Control

Our Dark Sky approved fixtures are designed to shield the light source, preventing light from escaping above the horizontal plane. This ensures that light is directed solely to the intended task or area, minimising unwanted upward light spill. Through precise optical control, we can manage the beam distribution to reduce glare and light spill. By using optics such as micro-prismatic diffusers and asymmetric distribution lenses, Tamlite's Dark Sky-approved solutions provide optimal light output while maintaining strict control over beam angles. This is especially crucial for street lighting, where uniformity and comfort are essential. Integration With Smart Controls Integrating smart control systems such as Tamlite Vision or motion sensors can further optimise energy usage and reduce light pollution. These systems allow lighting to adjust based on ambient conditions, occupancy, or time of day, ensuring that only the required amount of light is used at any given moment.

Bats & Artificial Light

As of August 2023, GN08 has been updated to include guidelines for modern LED light sources and their environmental impact, particularly on wildlife.

It introduces a "mitigation hierarchy" for lighting in areas where bats may be present, focusing on avoidance, minimisation, remediation, and compensation strategies to manage these impacts.

The update aims to balance the need for effective lighting with the protection of vulnerable species and their habitats. Artificial Lighting Guidance

Tips to Reduce Light Pollution

Dark sky off icon Turn off unnecessary lights and limit lighting to where it is truly needed.

Use motion sensors and timers and ensure lights are only on when they are required.

Dark sky dimmer icon Opt for dimmers and reduce brightness to limit excess light.
