Research into human response to LED lighting

As Government promotes use of this energy efficient lighting, SLL looks to provide evidence on when LEDs are truly better and how they affect the public.

The use of LED light sources for all forms of lighting applications is escalating at a rapid rate. The implementations are fuelled by political pressure on lighting energy savings and by the claims of higher efficiency characteristics of LED sources. However, some LEDs are made and supplied by companies that understand electronics, but may not understand lighting and the human response to light so well. This means that some inappropriate products may be on the market and some that are OK may not be supported by suitable or correct information to permit appropriate application of the products.

The initial phase of the SLL research will focus on the LED lighting characteristics affecting humans.

•  Measurement of flicker of LEDs currently available on the market

•  Assessment of the impact of flicker on users

•  Measurement of colour of LEDs currently available on the market

•  Assessment of the role of derived colour metrics
