Books are still my favorite source for professional development. I am busy in recent years also in tunnel lighting. I read many books, articles over past several years. I think this article is one of the best I read. IEEE is very much professional organization. I hope ITA will be like IEEE one day.

This article is from 1982. This is like wine. I read it in August this year. I thought it was printed in 2023. Very interesting and useful.
