footcandles delivered are more important than lumens produced.
Two major terms are often used in the process of defining the brightness of a light fixture:
The amount of lumens produced at a source does not directly correspond with the amount of footcandles delivered.
how bright it is at the source. Visible light emitted at the source. (Glare) Lumens does not accurately reflect the amount of light that actually reaches the eye of an observer.
how much light falls a certain distance away as usable light on the intended surface. The amount of working light perceived at the work surface.
As lighting technology has evolved, it is more important to understand a fixture's footcandle output rather than its lumen output.
Every lighting fixture design has unique light distribution characteristics. The distinction between footcandles delivered and lumens produced is especially important with LED fixtures, which are capable of delivering more directed light than legacy sources.
Fixture efficacy was traditionally defined as lumens/watt. How many lumens of light were produced for each watt consumed.
However! Lumens per watt CAN NOT give us the overall effectiveness of a fixture to deliver usable light in a specific application.
What customers are seeking in a successful lighting project is simply to maximize the amount of visible light that falls on a surface as usable light (footcandles delivered).
energybank fixtures feature patent-pending optimized optics to achieve greater footcandles of usable light delivered with maximum Visual Comfort Probability.
The innovative designs of energybank will always prioritize the optimization of the light engine as a system that delivers maximum footcandles without compromising performance or longevity.
energybank optics control/focus the energy produced with proprietary optics, delivering light uniformly to the work surface for superior visual comfort.
BRAND X FIXTURE
The Occupational Safety & Health Administration (OSHA) of the US Department of Labor has specific lighting standards for business.
The minimum lighting requirements of OSHA 1926.56 [Illumination | Worksite Lighting] are expressed in footcandles.
