Low Light Pollution Observatory Zone High Mast Light

Basic Info

The Selux Miro Linear series is for areas with strict requirements for sky darkness, such as around observatories, dark sky parks, and entrance roads to nature reserves. Its design philosophy is "light the ground, not the sky." Through precise optics and full cutoff design, it strives to contain all light below the horizontal plane, minimizing upward scattered light to protect the night sky environment.

Customer reviews

Thomas Jensen · Chain Supermarket Property Director

After installing high mast lights in our large parking lot,surveillance footage clarity improved noticeably,strengthening security for vehicles and pedestrians.The even,shadow-free lighting has received positive customer feedback for feeling safer at night.The well-designed pole height and angle effectively prevent light intrusion into surrounding residential buildings.

Michael Brown · Petrochemical Park Safety Director

The explosion-proof high mast lights for oil & gas fully comply with ATEX Zone 2 standards. Their specialized heat dissipation and flameproof joint designs eliminate ignition risk. Internal components remain dry after routine high-pressure washing, and the anti-corrosion coating is intact in the corrosive atmosphere.

Mohammed Ali · Large Logistics Center Operations Manager

The high mast lights in the logistics center parking and aisels are highly reliable.Paired with motion sensors for'light-on-approach,dim-on-departure'operation,energy savings are substantial.The high CRI lighting facilitates nighttime goods sorting and verification.The rugged construction withstands daily impacts with minimal maintenance required.

Product Description

Features

The luminaire uses special baffles and lenses to create a sharp"cutoff line,"where light is rapidly attenuated near the horizontal angle.Optional amber(PC-amber)or narrow-band LEDs can be specified;these spectrums tend to be less disruptive to astronomical observations and are more wildlife-friendly.Housing surfaces are dark and matte to reduce secondary reflections.Brightness is often dimmable,with further reduction possible late at night.

Specifications

Must comply with International Dark-Sky Association(IDA)or similar"Full Cutoff"certification standards.The Upward Light Ratio(ULR)requirement is 0%.CCT is typically limited to 3000K or below,with 2200K amber being recommended.Mounting height and spacing are carefully calculated based on the minimum safety requirements,not high brightness.

Applications

Installed within controlled zones(several to tens of kilometers)around astronomical observation facilities.Also used for access roads in"Dark Sky Communities"or national parks that promote astro-tourism.Here,lighting is not for display but to humbly serve basic safety guidance while receding into the background,giving way to the stars.

Frequently Asked Questions (FAQ)

Q：What are the key optical control metrics for these high masts?

A：The core is strictly controlling the Upward Light Ratio(ULR≤0%),i.e.,full cutoff.Also limit luminaire intensity distribution at all vertical angles to ensure light only reaches intended surfaces.

Q：What are the restrictions on allowable light source color temperature,and why?

A：Strictly limit high-CCT white light(e.g.,>3000K).Prioritize amber(~1800K)or narrow-spectrum amber LEDs because short-wavelength blue light contributes more to skyglow and interferes more with astronomy.

Q：What are the special design requirements for luminaire mounting height and angle?

A：Mounting height should be as low as possible while meeting needs.Vertical aiming angle must be precisely calculated and adjusted on-site to ensure the main beam is below the horizontal line and away from the observatory.

Q：How to achieve necessary while minimizing skyglow?

A：Use asymmetric optics to direct light precisely onto road/task surfaces.Implement smart dimming to maintenance levels after midnight.Combine with motion sensors for presence-based lighting.

Q：Does lighting within the require special approval and periodic testing?

A：Yes.Lighting plans typically require submission and approval by relevant authorities.Post-installation photometric measurements with professional equipment are needed for compliance,followed by periodic re-inspections.

Q：Besides luminaires,what other measures reduce light pollution?

A：Use dark pavement materials to increase reflectance.Design for shading.Turn off non-essential lighting during hours.Strictly control architectural facade lighting.
