Significant energy and cost savings and operational benefits can be achieved by replacing old and inefficient lighting with T5 and LED solutions.

The issues with inefficient lighting

15% of UK electricity is used for lighting and 70% of lighting is used within the commercial sector. Many buildings, particularly industrial and warehousing, are still using inefficient, original lighting.  The main problems with this are:

  • All lighting is switched on when the first person enters the building and stays on until the last person leaves.
  • The lamps and luminaires are inefficient and inflexible compared to modern fittings.
  • Different areas of the building require different levels of light, but the original systems were designed to provide fixed lighting levels, which leads to additional ‘task’ lighting being installed in ‘design’ areas and store areas being over-lit.
  • Lighting remains on, even if there are good levels of daylight available.
  • Lighting remains on, even though no-one is working in the area.
  • Older lighting operates at low frequency (50Hz) which causes stroboscopic effects with rotating machinery.

In summary, much of the lighting installed in industrial/warehousing environments is highly inefficient, inflexible and produces poor quality and/or incorrect levels of light.

The benefits

Significant energy and cost savings and operational benefits can be achieved by replacing old and inefficient lighting e.g Metal Halide, SON and switch start fluorescents, with T5 and LED solutions (incorporating automatic daylight dimming and occupancy control).

Typically, electricity used for lighting can be reduced by over 60% with energy efficient lighting. For a factory of 5,000m2 operating 24/7, this could equate to savings of £10k/annum, with a simple payback of 2 years.

Key benefits

  • Lighting only operates if someone was working in the area, saving energy.
  • The quality of lighting would be much improved and the high frequency operation is safer, preventing stroboscopic effects.
  • Light levels can be programmed in to each luminaire to match the task requirements.
  • Light levels can be modified if the area’s function changed, providing flexibility.
  • Lighting levels automatically dim down as levels of natural daylight increase.
  • Better colour rendition and vastly improved lamp life, creating better working environments and reducing maintenance costs/disruption.

How can CMR assist?

After an initial review of your lighting installation, if there are opportunities for improvement, we will carry out a detailed lighting survey and produce a written report, highlighting the following:

  • Existing running costs
  • Breakdown, by area, of recommendations
  • Lamp/luminaire type and mode of control
  • Improvements to lighting quality and levels
  • Maintenance requirements (lamp change frequency etc.)
  • Energy, cost and CO2 reductions
  • Project cost, ROI, simple payback and finance options
  • Phasing to minimise operational disruption.

We will then meet with you to agree finance options, timescales and project processes to dovetail in with your existing operational and fiscal policies, procedures and requirements. For more information, please download our information sheet.
