Emmetts UK Case Study

Emmetts UK

Emmett UK is a privately owned farming business that grows vegetables, salads and flowers for some of the UK’s leading supermarkets. They grow more than 95% of the products that they sell, with farms in Nottinghamshire, Lincolnshire, Wales and Spain. The company were looking to upgrade the current lighting system in place with high quality LED products throughout the site at Spalding, Lincolnshire.

The Requirement:

The client had a mixture of fluorescent tubes, GU10 halogen lamps, metal halide bay lights and sodium floodlights and were looking to reduce their energy consumption throughout the site to reduce their carbon footprint.
They also had on-going issues with the current light levels within their despatch and production areas which was causing picking and packing errors.

In addition to the lighting circuit’s high energy consumption within the temperature controlled areas, there is also more power consumed by the cooling system to maintain the desired temperature.
This is due to the inefficiency of the metal halide lights producing more waste heat that had to be removed by the refrigeration system.

This is often referred to as the coefficient of performance or COP, please see attached datasheet for full explanation.

Maintenance on the current lighting system was a very expensive task as accessibility to the bay lights was some what reduced by production machinery on site. A product with a lifetime increase was required to reduce this as much as possible.

The Solution:

After a site evaluation, the project specification team advised replacing the current lighting system with a highly efficient lighting system throughout.
The lights installed offered an increase in light levels in critical area’s whilst also reducing the total energy consumption on site by more than 70%.
The team over at Emmetts were very pleased with the results.

  • Annual energy saving of £74,954.47
  • Minimised picking and packing errors due to increase in light levels
  • Total energy consumption reduction by more than 70%

The coefficient of performance or COP (sometimes CP) of a heat pump is a ratio of heating or cooling provided to work required. Higher COPs equate to lower operating costs.

Extra Savings For Refrigerated Environments Explained

When LED lights are used to replace less efficient light sources, typically Metal Halide or SON Lighting, there is an additional saving gained when used in refrigerated environments. Download our free PDF with more information.

Polebrook Warehousing Case Study

Polebrook Warehousing

Airfield Warehousing based in Oundle, just outside of Peterborough are a professional warehouse storage, handling and transport that have been running for over 30 years.

Overview:

Their warehouse storage site had been rebuilt in the 1980s and has over 110,000sq ft of purpose-built dry, secure warehousing space together with large areas for outside storage too. They were looking to upgrade the current Fluorescent and Sodium bay lighting system in place wit high quality LED Products.

The Requirement:

The client had on-going issues with the current lighting system that required an energy saving solution, the issues included the following.

  • Exceedingly high energy usage within low traffic warehouse areas
  • Low light levels within warehouse areas creating picking and packing errors
  • External CCTV system was not effective at night time due to poor lighting levels from current sodium lighting units
  • Emergency lighting did not conform to regulations
  • High maintenance costs in comparison to LED alternatives

The requirement from the client were mainly to minimise running costs using Prolite LED lighting products. An increase of light levels throughout the site was required to decrease the picking and packing errors and also increase the clarity of the CCTV system in place at night time. All internal units required the option to include an emergency option to fall in line with current legislation.

The Solution:

After a site evaluation, the project specification team advised replacing the current lighting system with a bespoke LED lighting system. The light levels were all predicted before installation took place by our in-house lighting design team.

This was to ensure that a genuine increase of both LUX levels as well as uniformity of light would be achievable in both internal and external areas. A programmable sensor system was also designed within the fittings to ensure any low traffic areas of the warehouse would not be illuminated whilst no workers were within the area, maximising energy savings for the site as much as physically possible.

Airfield warehouse now have a low energy sustainable lighting system. The warranty period in turn guarantee’s that the energy savings will be made.

PC Howard Case Study

PC Howard LTD

PC Howard LTD are one of the UK’s leading third party logistics providers and were looking to modernise the current lighting systems in place. This was throughout their busy 24 hour depot based in Kings Cliffe, Northamptonshire and included offices, corridors, despatch centre, warehouses and external yard areas.

The Requirement:

The client required a long term, low-energy solution to their on-going issue of picking and packing errors within their despatch, warehouse and external yard areas. The lights needed to offer an increase in light output to reduce these errors, whilst minimising both energy consumption and maintenance costs.

Other areas within the depot included offices and corridors where low energy replacement products were required, whilst maintaining current light levels on site.

The Solution:

After a site evaluation, the project specification team advised replacing the power hungry 400w metal halide bay lights with High Output LED Tray-Bay fittings. Using just 144w’s of energy each, these units were able to increase light levels by more than 30% across the main despatch area’s of the warehouse.

The running costs of the site’s lighting system has now been reduced by more than 70% and also offered a return of investment on materials of just 1.4 years.
