Advance your knowledge of lighting Successful lighting professionals must be able to incorporate into their work many new technological and scientific developments. Examples: solid state lighting sources; humans' perception of light as they age, sustainability and the integration of daylighting with electric lighting; the effects of light on human health; to name a few. Clients rely on and, indeed, expect lighting practitioners to know their specialties and to make well-informed decisions and recommendations on the client's behalf. That is why the 10th edition of the new IES Lighting Handbook is an essential knowledge reference for anyone in lighting.
