Replacing older style lanterns 1:1 is usually an inaccurate strategy for retrofitting a commercial space – particularly in high bay areas. It’s also crucial to use luminaires which have been designed with your working environment in mind; vibration, prolonged use and atmospheric dust can all significantly reduce the functionality and life expectancy of generic LED luminaires.

​

Floor space, function, ceiling height, frequency of use, and the position and placement of static and moving fixtures and assets all affect the design of a lighting scheme. A layout which worked with high pressure sodium or halogen lanterns typically doesn’t work effectively with high quality LED luminaires, as light intensity, distribution and directionality are usually very different.

​

When retrofitting a facility with a pre-existing lighting scheme, we’re often able to remove 20 to 30% of the light fitting points originally required to fully illuminate the space below. That means that you’ve removed redundant luminaires from your lighting layout which on a 1:1 replacement would have been consuming energy without providing any benefit.

​

A properly designed lighting layout also helps to eliminate areas of shadow – particularly in spaces with high-sided shelving and machinery – and control glare, which is amplified by reflective surfaces and needs to be managed with the correct choice of optical lens.

​

Your outcomes:
 

• An increase of light levels by typically double at floor level, at a suitable colour temperature
   

• Better colour rendering, making yellow and white safety / guidance markings far more visible and delineated (correct use of delineated?)
   

• Elimination of areas of shadow, light pooling and glare, providing even illumination and comfort for employees working below
   

• Maximum possible energy and carbon efficiency, typically with savings in excess of 80%, and a rapid payback period facilitated through reduced lighting energy overheads
   

• Correctly deployed emergency lighting, where required
