Proper lighting is critical for a productive work environment. It is important that the system provides effective illumination for workers and pays attention to the relationship between optimal lighting levels and task completion. Here are some helpful tips on lighting:
1.Most offices should
strive for an illumination level near 35 foot-candles; higher for paper
document activities and a little lower for computer-only tasks.
and manufacturing plants should keep lighting levels between 25 and 50
foot-candles. The more a facility relies on machinery and equipment to complete
tasks, the higher that number should be.
use of indirect lighting fixtures. Distributing light upwards and using
shielded light fixtures (diffusers, lenses, louvers, etc...) are effective in
minimizing screen glare.
lighting can have a variety of colors and will affect the mood of occupants. A
low-glare environment is visually comforting and it augments employee
productivity and satisfaction. A bulb rated at 3200-3500 Kelvin degrees (K) is
considered a “soft white” color that also decreases glare. Avoid using fluorescent
lamps that exceed 5000K for offices.
facilities have installed high bay fixtures that use 250-1000 watt metal halide
HID lamps. These lamps lose lumens (light output) over time.
Have a replacement
schedule in place to ensure proper lighting on a continual basis.
conditions paired with glare and frequent and/or lengthy stretches of computer
work can create a multitude of physical problems that negatively impact
workers. Workers in this environment can experience eye discomfort,
blurred vision, headaches, and pain in the upper back, neck, and shoulders.
Consider improving your environment in the following ways:
monitor closer or change the angle and/or height of the monitor to a position
that is most comfortable and minimizes screen glare. Adjust contrast and
brightness on the computer if necessary.
font being used on computer documents. A font of 12 or higher is recommended
for most people.
from sitting in one spot or staring in one location for too long.
eyes checked out by a licensed eye care professional. They may be able to
diagnose a condition before it becomes severe or suggest ways to minimize its
5.Check the light levels
at your desk. Consider replacing old lamps, installing light controls, removing
light obstructions (i.e. filing cabinets, trays, adornments, etc…), and adding
supplemental lighting such as a desk light. Any of these changes can
improve vision performance.
