TECHNOLOGY IN ACTION
Scott Safety cuts its lighting energy consumption by 81% S
COTT Safety, a leading provider of life safety protection products and services, is now also leading the way in reducing energy consumption.
With the help of award-winning lighting manufacturer MHA Lighting, Scott
Safety, a Tyco Company, is set to cut its lighting energy consumption by 81% at its Skelmersdale site.
With its award-winning low energy luminaires and ability to design bespoke precision lighting solutions, MHA Lighting was chosen to replace all the existing T5 fluorescent fittings in both the Warehouse and on the Shop Floor.
After trialling various fittings to find the optimal light colour, MHA Lighting’s
TiLites were chosen that supplied 80CRI and 4000 kelvin colour temperature. This combination can significantly enhance the working environment which will also aid precision working and contribute to a greater feeling of wellbeing amongst the staff.
The project saw a total of 281 MHA lighting LED luminaires with 23 sensors installed – this included 113 award winning High Bay TiLite 70 fitting (82 watts including ballast) and nine TiLite 30/120 (45 watts including ballast) installed above the shop floor and 46 Oval High Bay 150watt fittings in the warehouse.
This reduced annual lighting energy consumption from 263,907kW/h (annual
cost of £26,391) to just 51,730Kw/H. Annual energy bills have therefore been reduced to just £5,173.
Through their low-energy LED Luminaires MHA Lighting was also able to achieve a reduction in Co2 production of 84% in the shop floor area and 64% for the warehouse. This equates to product lifetime Co2 savings of 2,003 Tonnes (115 Tonnes per year).
Pete Osborne, Production Engineering and Facilities Manager for Scott Safety, said:
“Not only are we seeing real cost savings on our energy bills but the light
colour, output and uniformity provided by MHA is superb and our staff are benefiting from the improved lighting.
“With the integration of various intelligent controls we have made further reductions on our energy usage and given that the units will run maintenance free for seven years we will also decrease our maintenance costs.

At current operating hours the fittings offer a useful lifetime of 16 and 25 years for the shop floor and warehouse respectively. Throughout life they require no maintenance saving Scott Safety a further £51,905 in maintenance costs during product lifetime.
This takes overall lifetime savings for this project to £419,953. Tom Harrison, MHA Lighting MD, said: “MHA Lighting ran a series of trials at Scott Safety before the customer
selected the light colour that they felt provided the ideal working environment for their employees.
“Because of the high quality sky lights in the factory we were able to utilise ambient day light sensors so that during day light hours the fittings will burn at a fraction of their total output thus maximising energy savings further.”

AD9364 Wideband RF Transceiver
programmable RF transceiver from Analog Devices. The new AD9364 operates from 70MHz to 6.0GHz and targets point to point communications systems, cellular base stations, and general purpose radio systems. It is ideal for 3G and 4G base station applications and requires only a 1.3V power supply. The receiver section supports independent automatic gain control (AGC), DC offset correction, quadrature correction, and digital filtering. This improves reception by boosting weak signals and reducing interference. The transmitter is designed for high output signal accuracy with an emphasis on minimizing noise. On-board low power Phase Lock loops (PLLs) generate precision frequencies for both transmitter and receiver. A voltage controlled oscillator (VCO) and loop filter are also on chip. The AD9364 is controlled by a standard SPI port and four input control pins. In addition, four GPIO pins can be used to either control external peripherals or function as slaves for internal control of the AD9364.
