About Us

Paul Metcalfe International Ltd (t/w PM International and Light Symphony) has been designing and manufacturing high quality electronic parts for over 30 years.

The company started in Hemel Hempstead in 1992 building and installing bespoke industrial control equipment to the international newspaper industry. This equipment is expected to last 10-20 years so quality and reliability are paramount. Today we work in partnership with international companies like Bosch, Panasonic and Siemens to supply motors, drives and controls to major news-print organisations around the world, while still supporting our original products. 

Light Symphony shares much of this technology and has been developed in-house to provide a robust, reliable and expandable solution for professional outdoor lighting control. Light Symphony began in 2000 as a 'wired' system, uniquely providing control over wide-area lighting schemes. 

The new wireless Light Symphony system has been designed to exploit the latest in long-range radio technology, reducing costs while increasing flexibility.  On a number of projects the reduction in labour from trenching and running armoured cabling has meant that Light Symphony even paid for itself!

The modular system gives our installers and users the flexibility to work on anything from small garden plots to large commercial projects with the same products that they are used to using growing with them.  Easy to expand, even easy to re-configure once installed, our controls allow for even the most indecisive client to be effortlessly accommodated. 

We understand the limitations of many other control systems and set out to eliminate all of them in creating Light Symphony.  If you need advice on how our products do this in detail and cannot find the answers on our web site, then please do call us or when viewing a product use the "Ask a question about this product" for further information. We are even happy to help you through your specific options, if you email or fax us your current project plan and known details and we'll help get you started - TODAY!!

Light Symphony is run by a strong team with a focus on good customer service and backed up with good technical knowledge. We take pride in the products we build to ensure they provide a long and reliable service. We don't hide behind any anonymous web sites, re-sellers or distributors. We like to hear from you, whether it's about planning your project, after sales care or just feedback on our products - please get in touch.
