Low Energy Lighting
VMI are always following trends in technologies of TV production techniques and the field of lighting hire is no exception.
BBC Low Energy Lighting Guidelines - © 2011 BBC
The BBC is excited to launch a unique “one‑stop shop” Guide to Low Energy Lighting (LEL) for TV production. It is a comprehensive Guide on LEL, which will be useful for Lighting Directors, Studio Managers and Production Teams.
Up to 80% of the energy consumption in a production is from studio lighting. There are many advantages to be gained from using LEL – not least the reduction in energy consumption and carbon footprint. There are maintenance savings, as lamps last longer. There are more effective studio operations: for example, LEL can offer more flexible and dynamic ways to change light colour.
This Guide answers questions. What are the advantages and disadvantages of using low lighting equipment? How to introduce energy efficiency into your lighting design? And how to manage your production to reduce its energy consumption?
The Guide is a useful resource for TV Lighting Directors. It outlines the latest thinking on the colour rendition as well as the impact of accessories on overall luminaire efficacy.

There is a useful matrix in section 4, which explains the various characteristics of LEL equipment.
Section 10 summarises actual measurement results – lux levels and colour rendition in a studio environment for currently available LEL equipment.
There are examples of TV productions which have switched to LEL, proving that it is possible to achieve a lighting solution that is wonderfully lit, cost effective and sustainable.
