This data uses candlepower, reflector type and fixture type, at the light source to project the number of footcandles
of illumination at a target.
In the study, bright lights averaged 60 footcandles
and the dimmer lights 25 footcandles
For the open offices, 25 footcandles
(fc) [269 lux] and a 4:1 maximum-to-minimum illuminance ratio were selected as the ambient workplane illuminance and uniformity criteria.
Company's 49 or 89 Enviroguard tube with Vision+ optics increases footcandles
Most interior plants require a minimum of 80 footcandles
to 150 footcandles
to thrive and grow.
Most areas of concern, except compliance with the National Fire Protection Association (NFPA) Life Safety Code, call for general illumination above 10 footcandles
Under fluorescent lighting, the Mall achieved around 12 footcandles
at 30 inches above the floor.
To make the mannequins in the window pop, the team used LED track heads with 350 footcandles
These values are minimum average maintained footcandles
The specially engineered reflectors also minimize glare and deliver a substantially higher percentage of usable footcandles
on key work areas than traditional HID and fluorescent fixtures.
, requiring four poles in the main yard, each holding four Venture 400-watt pulse start lamps.
3) Generally, a lighting system with deep-cell parabolic louvers will provide about 50 footcandles
of light if installed in an 8[inches] by 10[inches] office.
