Here are some links for those interested in lighting. I have checked them out and believe they are useful. Sadly there is so much stuff out there which is frankly awful.
Please use the comments below if you find the links useful and to add any resources you have found and recommend.
Although every care has been taken by SCDA in the recommendation of these resources, they exist on external servers outwith the control of SCDA and they have not been subject to detailed evaluation. Accordingly no guarantee is given by SCDA as to their suitability. SCDA shall not be responsible or liable for any loss or damage whatsoever arising by virtue of accessing these links.
