The LET Diploma in Lighting Design course is fully supported by tutors and mentors: lighting designers and specialists in all subject matters. So, whilst in the first instance, reference to the course notes or to personal research should be your route to greater knowledge and understanding, where you are struggling or frustrated then you should contact the LET project tutors or the LET co-ordinator, who will be able respond with assistance to your problems and queries.
The suggested study time indicated for each module and chapter is intended as a guide, not a target! You may wish to spend considerably more time than suggested; equally, if you already have significant knowledge in some of the chapter subjects you may be able to reduce your study time from that suggested. You are the best person to decide – based upon your previous education, qualifications, employment and other time commitments.
It would also be of great benefit to you to become involved in professional lighting matters by attending seminars, events, and exhibitions. The simplest way to do this is by joining and being active in professional lighting associations. In undertaking the course you qualify for Student Membership of both the Society of Light & Lighting (SLL) and the Institution of Lighting Professionals (ILP) to help you on your way. Please note, although the provision is automatic, you still need to complete the relevant application forms; we encourage you to do this as, in addition to the hard copy SLL Code for Lighting and SLL Lighting Handbook which you will be given, you will also gain free access to the Knowledge Portal with access to hundreds of publications and lighting guides. There is also tremendous benefits to be had by joining the greater lighting community, so please do join.
Please be under no illusion, the LET Diploma in Lighting Design is a huge commitment to progress your education in lighting; the Diploma is an advanced education learning course and its outcome should be one of professional understanding encompassing the three attributes, of knowledge, experience and vision; learning ‘by rote’ at this level is not recommended - the secret is time investment, perseverance, discussion and above all, enjoyment.
