Lighting spaces that feel good, optimize performance and save money
Common Complaints from poor lighting
difficulty seeing document or screen (too much light or glare, or too little light or shadows),
dry burning eyes, and headaches
The Cause of poor lighting
- Fluorescent bulbs produce UV light, which is only partially converted to light in the visible spectrum.
- In addition to UV light, the visible radiation emitted by fluorescent light sources consists of three spikes (magenta, yellow-green, and orange), with minimal if any other wavelengths contributing to the output.
- People with sensitive vision, particularly in the scotopic (low-lit) range, and low-spectrum lighting can experience dizziness, headaches and nausea caused by the spikes and gaps in fluorescent light output.
LED LIGHTING SOLUTION
- Unlike their fluorescent counterparts, LEDs are 100% visually efficient; that is, they only produce radiation in the visible range, with virtually no harmful UV or wasted infrared.
LED bulbs contain no mercury or hazardous waste, and are 100% recyclable
The smooth curve and constant irradiance across the full spectrum of visible wavelengths results in more saturated, vivid, discriminable color rendering and effortless visual acuity
- Fully directional down-lighting also provides more illumination on working surfaces, rather than the diffuse glow produced by the gas-filled fluorescent tubes.
- The correlated color temperature, color rendering, and luminous efficacy of LED lights combine to improve visibility to create a better learning or working environment.
- Our bodies’ roughly 24-hour cycle is governed by hormonal responses that are triggered by full-spectrum light – light provided by sunlight and LED, but not fluorescent.
- When the light needed to trigger circadian responses is provided, alertness, attention and participation increase. We have all experienced the relief of leaving a fluorescent-lit classroom or office and stepping outside for a break on a sunny day. The spectral output of fluorescent lights is to blame.
- In the bleak winter months, many people are diagnosed with Seasonal Affective Disorder (SAD), while many more self-diagnose their yearly “winter blues.” LED lighting is used in the treatment of SAD, and also has been shown to improve mood, decrease stress, and create a generally healthier and happier environment – all because the lighting spectrum mimics that of natural sunlight.
