We are really looking forward to the 2017 AGM, Presidential Address and Awards, starting at 6pm on 25 May at The Royal Society in London. We hope that many of you will be able to join us to celebrate with our award winners and, of course, hear the presidential address from incoming president Richard Caple. It promises to be a varied and enjoyable evening, and is always a great opportunity to catch up with fellow members. Many thanks to all of the 13 teams who joined us for Ready Steady Light 2017 at Rose Bruford College, in Sidcup (see p5). This year’s event was very enjoyable with the sun shining and highly enthusiastic competitors. Congratulations to all the winners: Future Designs who took the Peer Prize, WSP Parsons Brinkerhoff who lifted the Technical Prize and Light Bureau who won the Artistic Prize, supported by the IALD. Many thanks to our partner, Rose Bruford College, their students who delivered the event, and this year’s sponsors who provided the indispensable lighting equipment: Philips, Whitelight, Lee Filters and Erco. The technical and publications committee have been busy (they are always busy, of course) and we now have Lighting Guide 0, together with the new Factfile 12 available on the website, both free to download by members and non-members alike. LG0 is an introduction to lighting so if you know of people who could benefit from the guide please do pass on the links. Factfile 12 tells you all you need to know about thermoplastic diffusers in luminaires and fire safety. You will find all of the Factfiles very useful in your dayto-day design work. The next Lighting Guide, LG15 on Transportation, is imminent. Another upcoming publication is Factfile 9 which details the 2016
update to the Building Regulations and all the relevant documents in England, Scotland and Wales. We approach the last Masterclass of the 2016-2017 season at St Martinin-the-Fields on 18 May. The Knowledge Series: Human Responses to Light has been very popular and we thank all those who have attended over the series. We also thank our supporters: Holophane, Thorn, Trilux and Xicato for their input. Many thanks to all who have renewed their annual subscriptions and those who have contacted us regarding upgrading their membership to Associate (AMSLL) and Member (MSLL). We have been happy to assist with your membership upgrade process. As the deadline date for 2017 subscriptions looms we encourage those who have not renewed their membership to do so or contact
