Fashioning an efficient solution

Hi-Max and Skylux LED fittings combined with LED downlighters and KNX lighting controls system were installed in the 15,000m2 cross-dock property in Warrington’s Omega North Business Park. Hi-Max LED is a range of luminaires for mounting at height, and is developed especially for production facilities and high warehouse racking.

Luxonic was charged with the task of providing lighting schemes for both the main warehouse and the 1486m2 of office space that achieved the desired lux levels whilst reducing energy usage. Minimising the amount of maintenance required was also vital in designing a system that keeps running costs as low as possible for Hermes. 

 

The Hi-Max LED is a high-power suspended luminaire designed to be mounted at heights of up to 18m and is applied in the main warehouse to achieve the necessary lux levels for the large open space. The lighting scheme uses fewer fittings than the original concept design and therefore reduces both power usage and future maintenance costs for the client.

The luminaires use high output Cree XP-E LEDs, and they operate in the ambient thermal range of –30 to 30°C. The Hi-Max fittings can either be suspended or surface mounted, and are said to be highly efficient, with the option of integral dimmable control gear which contributes to energy savings and a reduction in CO2 emissions.

Luxonic significantly increases the life expectancy and reduces the maintenance costs of the luminaires through the protection of the LED array by the optic, minimising environmental damage. A presence detector, suitable for mounting heights in excess of 15m, means that the fitting can be set to switch between full output when the warehouse space is occupied and a dimmed light output when unoccupied. The luminaires can be programmed to turn off after a period of inactivity, or if there is sufficient daylight to light the space. The flexibility of the HI-MAX LED luminaires through programming options and customisable optics means that they can be suited to the individual preferences of the user, whilst reducing energy costs. 

Adam Leach, estates manager, Hermes, said: "Our distribution and handling centres require a high level of lighting to meet health and safety criteria and ensure a pleasant working environment is provided. It is vital that these lighting systems are as energy efficient as possible to reduce our carbon footprint and energy use. The Luxonic luminaires, together with the specially programmed lighting controls, look to keep energy wastage to an absolute minimum while the quality of lighting in the property is uncompromised.”

The Hermes warehouse also benefits from a site-wide KNX lighting controls system as well as the constant monitoring of the luminaires via DALI to reduce energy consumption where possible. Presence detection and daylight linking increase efficiency further, as they allow lighting to be on only when someone is present and automatically adjust the luminaire’s output, and therefore energy use, when monitoring the amount of natural light contributing to the lighting levels. 

The lighting scheme also comprises downlighters from Luxonic’s V-LED100 and 200 ranges. The V-LED100 is a high efficiency low wattage fixed, recessed LED luminaire with very wide, medium and narrow reflector options. 

The V-LED200 downlighter is a newly-developed light engine and optical system integrated into a die-cast aluminium heat sink resulting in a luminaire that Luxonic says is twice the efficiency of a compact fluorescent with a minimum 70% lumen maintenance. Luxonic has designed its downlighters to be energy efficient and comfortable for users by controlling brightness in conjunction with a white reflector, as opposed to a specular reflector. They are suitable for corridors, toilets and open-area lighting.
