10 Days with a Lightmeter: A Light Level Journal
Lighting Design Alliance principals present educational seminar at Lightfair 2010 in Las Vegas
Light level calculations and photometric studies are an essential part of the lighting design profession. But how do these studies relate to our everyday experiences with light? What do the common IES design levels of 1, 5, and 30 footcandles really feel like? In an attempt to gain a more intuitive understanding of footcandles, we spent 10 days and nights with a lightmeter at our sides 24/7. We took light level readings at various times of day in many different locations, and kept an “illuminance journal” to note our impressions. Join us we share our insightful (and sometimes comical) observations.
• Gain an intuitive sense of light levels. What does a certain light level feel like in various situations?
• We are often asked if there will be enough light. Can we define enough?
• How do perceived lighting levels change with environment and locale?
• Can we make do with less light than is typically recommended? Can we use less light, feel comfortable and promote sustainability? Appreciate the human eye.
