You have selected the £ Custom membership level.
We are delighted that you would like to join us. Before completing the registration form please consider how much you are able to give to support us. We have kept the membership subscription low in order to make it possible for everyone. However if you are able to include a donation on top of your membership subscription so that you contribute £5, £10 or £20 per month, this will help us engage with government across a wider range of lighting issues, offer more practical support to light-sensitive individuals, and increase public awareness of emerging research on lighting and health.
