GL Hands-on Light Measurement Workshop at LFI 2018 in Chicago

Once again we are inviting all lighting professionals to take part in our light quality control workshop: Hands-on Introduction to Light Measurement & Standards. This time we will welcome you during the Light Fair International 2018 at McCormick Place - Chicago, Illinois USA. You will learn light measurement start to finish, from terminology, equipment and practices to hands-on with commercial measuring tools. You will measure fixtures, produce measurement files and apply these in lighting design software.

This course teaches light measurement principles and practices. We begin with terminology and key CIE and ISO standards, including LED concerns such flicker and photobiological-hazards. We progress to measurement techniques and processes, focusing on best practices. Putting this knowledge into practice, everyone performs hands-on measurements using professional systems. You will measure modules and fixtures, generate IES standardized files, and load these into lighting planning software, seeing the entire process from end to end, learning the real-world, practical aspects of lighting science. Each course module includes an open question and answer session to address specific needs and unique requirements of participants.
