The Ayrton Series LED high bay has been developed to provide a robust lighting system to illuminate challenging environments.

The Ayrton Series provides a solution for elevated or awkward mounting positions and projects requiring high target lux levels.

The Ayrton Series has over 30 optic and light control variants (including super-low glare 10° beam angles and glare shields). Combining the light distribution and mounting options, the Ayrton high bay lighting series can be tailored to suit a vast array of industrial environments including aircraft hangars.

Also available with DALI2, 3hr emergency and wireless controls, the Ayrton Series can be easily integrated into a larger project.

Polar: solid green C0–C180, dashed blue C90–C270, dotted amber the plane through the brightest direction when it lies between them; rings at 25% steps of the peak. Isolux: the footprint on the floor with the fitting aimed straight down, contours at 50%, 25% and 10% of the brightest point, grid in mounting heights (H). Both are drawn from the first measured file for that optic.

DESIGN FEATURES

High Bay lights designed for PURPOSE

The Ayrton Series modular design incorporates CREE XPG-3 LED chips and Philips Xitanium drivers as standard. This, alongside 10kV Surge Protection (or optional 20kV) and IK08 impact resistance results in a low maintenance fitting. High power, narrow beam angle options provide an excellent solution for extreme mounting heights such as hangars and mega-structure fabrication facilities. Modular Design - IP67 conformance is ensured by individually pressure testing each LED module prior to assembly with the light's chassis. LED module spacing was assessed to maximise air convection through the fitting; improving thermal management and the product's lifespan. Product Finish - The light comes with the choice of Grey, Black or White colour finishes. The standard AkzoNobel polyester powder coat can be upgraded for increased salt corrosion resistance. Surge Protection - The PCB has TVS (Transient Voltage Suppressors) to protect the LED chip from voltage transients induced by lightning. Combining this with independent SPDs provides a surge protection of 20kV/10kA as per ANSI/IEEE C62.41.2-2002. Optics - 14 varied optics are available which include: 5 asymmetric, 7 symmetric, backspill guard and frosted diffuser (to reduce glare).
