(4 lux), which is significantly less than the 0.
We asked Facility 1 to replace all the missing bulbs, which brought it close to 50 foot-candles
However, because the ceiling absorbs some of this light, it requires more foot-candles
to achieve adequate lighting.
Peter Boyce (Lighting Research Center) presented data that show people don't feel safer at lighting levels of more than 5 foot-candles
, debunking the "more-is-better" myth that pervades nighttime lighting practices.
are only part of the picture, however; the reflectivity of the objects being illuminated must also be considered.
In general, the study found that sites with lighting levels below three foot-candles
were given low security ratings, usually between -4 and 1.
After examining numerous LED products I determined that Seesmart was the one I'd want installed in my buildings as there bulbs provide higher foot-candle
readings at lower wattages compared to the competitors.
In a very short period, we expect to see this trend grow, as the future will be more about sustaining lighting ratios rather than meeting the high total foot-candle
levels of the past.
To date, xenon light remains incomparable in its ability to provide brilliant and dependable 6000[degrees] K, 20,000 foot-candle
illumination to the surgical field.
is equivalent to the illumination produced per square foot by one candle at a distance of one foot.
Before LED lighting fixtures were installed, the foot-candle
reading averaged 40 fc.
With higher quality light, we've more than doubled the foot-candle
readings within our facility," Barney says.
Model XL 150-2 offers bright Quartz Halogen 200 watt illumination, 3600 [degrees] Kelvin color temperature, 4800 foot-candle
output to a fiber optic headlight, world wide power (100/240v - 50/60Hz), and fits most cables.
is a unit of illuminant equal to one lumen per square foot.
Standard Electric supplies all of Timberland's in-store lighting, including the new LED lamps which are more than twice as efficient as the comparative foot-candle
incandescent bulbs being replaced.
