Light Sensitive materials

LED Usage in Museums and Art Galleries

by: Raghuram Petluri; Roger Sexton

Introduction

LEDs provide an energy and maintenance saving alternative to halogen for museum lighting. Previously high Color Temperature single phosphor corrected white LEDs had shortcomings with gaps in the spectrum affecting accurate color discrimination and high outputs / spikes in the blue area affecting color degradation. Recent improvements in LED technology make their usage ideal in all areas, light sensitive and insensitive alike. This paper takes the Artist Series module from Xicato to quantify this statement.
